However, since infections often clear up on their own, it is easy to give credit to an alternative therapy when it actually had nothing to do with resolution of the problem.

A new study conducted in the United Kingdom found that the diagnosis of celiac disease (autoimmune reaction to gluten) increased fourfold during the past 20 years. However, the diagnosis of a related skin condition (dermatitis herpetiformis) decreased by more than 50 percent. The researchers speculate that this may be due to earlier diagnosis of celiac disease preventing progression to dermatitis symptoms.

Consuming a gluten-free diet is challenging for those with celiac disease. However, some protection against the damage from unintended gluten consumption may be available in the future. A 6-week study exposed people with celiac disease to daily gluten consumption. Those who consumed a specific gluten-digesting enzyme product together with the gluten-containing meals had no detectable intestinal damage.
Potential new treatment may protect celiac patients from gluten-induced injury

A review of research on vitamin D and mortality pooled the data from 32 studies. Their analysis indicated that greater blood levels of vitamin D were associated with a significant decrease in mortality. The greatest benefit was achieved at blood levels that require a daily intake of about 1,000 IU of vitamin D3. The recommended upper limit for vitamin D is 4,000 IU per day.

Using an obese and insulin resistant mouse model, researchers found that supplementation with retinoic acid (a compound formed in the body from vitamin A) reduced the accumulation of body fat (especially abdominal fat). Retinoic acid also helped to normalize blood sugar levels and improve cardiovascular health. Retinoic acid is toxic at even moderately high doses (like the retinol form of vitamin A), so we have much to learn before this research is applied to humans.

Although less than one percent of the U.S. population has celiac disease that requires a gluten-free diet, there has been a major trend to use "gluten-free" on labeling of foods and meals in restaurants. On the surface, this would seem to make things easier for people with celiac disease. However, this is not the case when those processing or preparing these foods do not carefully exclude any potential source of gluten, including sources as seemingly minor as most soy sauces.

The bacterium Helicobacter pylori (H. pylori) is considered to be responsible for three out of four stomach ulcers, two thirds of all gastric tumors and practically all duodenal tumors. When it causes these problems, the proper antibiotics can cure them. However, more recent research also indicates that the presence of H. pylori in the body may benefit the immune system - as long as it is kept under control.

When well-controlled type 2 diabetics were fed 50 grams of whey protein 30 minutes before consuming a high glycemic index breakfast, their blood glucose response to the breakfast was reduced by 28 percent compared to when they only consumed water prior to the meal. Well-timed protein consumption appears to be important for managing blood glucose levels in diabetics.
In people with diabetes, consuming whey protein before meals could help improve blood glucose control

Omega 3 fatty acids and osteoarthritis: Osteoarthritis is the type of arthritis associated primarily with joint injury and the type of wear that occurs with aging. A study of obese mice that were exposed to arthritis-inducing joint injury found that a diet rich in omega-3 fatty acids significantly reduced arthritis severity compared to a diet higher in saturated fat and omega-6 fatty acids. The degree of obesity in the animals was not associated with severity of the arthritis.

Alcoholic fatty lung: Excess alcohol consumption is known to cause fat to accumulate in the liver and slowly damage it. This is commonly called alcoholic fatty liver disease. Researchers studying rats found that heavy alcohol consumption also led to fat accumulation in the lungs. Since rats are known to differ somewhat from humans in how they metabolically handle fat, it remains to seen if this applies to humans as well.

Vitamin D Supplementation: A large review of multiple studies concluded that vitamin D supplementation, with or without calcium, does not significantly reduce the risk of heart attacks, strokes, cancer, or bone fractures. These results seem to indicate that nutrient adequacy is more important than excess. The Institute of Medicine's Tolerable Upper Intake Level (UL) for vitamin D is 4000 IU (100 micrograms). The Expert Group on Vitamins and Minerals of the Food Standards Agency, United Kingdom recommends that daily intake of vitamin D from supplements not exceed 1000 IU (25 micrograms).

Beef and Blood Pressure: A study of 36 people (ages 30 to 65) with normal health tested the effect of four different diets on blood pressure. The diet with the most lean beef (about 5.5 ounces/day) in the daily fare resulted in the lowest blood pressure. Each diet period lasted for five weeks, so it is not know if this effect would still occur over a longer period of time.

The effects of diet and nutrition on health are typically expected to have an impact only after months and years of making a change. However, people with chronic obstructive pulmonary disease had beneficial changes in lung function when they reported recently consuming fish, grapefruit, bananas or cheese. Exactly what this means is not clear, but it indicates the possibility that some foods may influence lung function within a fairly short span of time.

It has been known for some time that the lower intestinal cells use a small fatty acid produced by bacteria as a major energy source. Known as butyric acid, this fatty acid also has been shown to benefit the immune system and reduce inflammation in the colon. Supplements of butyric acid may benefit those with various types of bowel diseases.

A study conducted with rats found that adding fructose to a high fat diet increased fat accumulation in the liver. Although this may provide a small piece of information related to the causes of non-alcoholic fatty liver disease, the study did not compare fructose to glucose and rats are known to handle sugars and fats differently than humans. So, be careful when trying to apply the results of this type of study to human health problems.

Research volunteers were fed either one or two pounds of cruciferous (cabbage family) vegetables daily for two weeks. The effect of this on systemic inflammation markers was measured. One out of four inflammation markers was reduced, but only in those consuming the two pound dose. Because the cabbage family contains a natural toxin to the thyroid, consuming this amount of cruciferous vegetables on an ongoing basis could damage thyroid function, especially without consuming adequate amounts of iodine (such as iodized salt).

Diabetes and Calcium: Many factors are involved in the development of type 2 diabetes. A new study adds elevated serum calcium levels as a risk factor. However, this is unlikely to be related to calcium intake. Since serum calcium levels are regulated tightly by hormonal mechanisms, elevated serum calcium likely represents maladjusted hormonal changes.

A large study of postmenopausal women found that those with the greatest amount of potassium in their diets had a lower risk of all types of stroke and all-cause mortality. Most people in the U.S. do not reach recommended levels of potassium intake. Some key foods that are high in potassium include bananas, papayas, oranges, prunes, raisins, potatoes, tomatoes, beans, lentils, salmon, milk, yogurt, and coffee.
Potassium-rich foods could lower stroke risk in older women

Sugar and Cardiovascular Disease: High blood sugar levels, as seen in diabetes, are known to increase the risk of cardiovascular disease. New research indicates that some compounds produced from sugar in the body can bind to and modify 'good' cholesterol (HDL), making it 'go bad.' It remains to be understood how significant this effect of sugar may be.

Omega-3 and Epilepsy: Adults with drug-resistant epilepsy experienced a 33 percent reduction in seizure frequency while taking three fish oil capsules per day providing a total intake of 1080 mg of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA). When the dose was twice this amount, seizure frequency increased to the same level as taking a placebo. Although, omega-3 fatty acids are clearly not a 'cure' for epilepsy, the proper level of intake may be an important component of overall treatment of epilepsy.

Hookworm Treatment for Celiac Disease: When hookworm parasites live in the small intestine, they protect themselves from immune system attack by secreting a protein that reduces inflammation. When 20 hookworms were introduced into the small intestines of eight volunteers with celiac disease, they became tolerant of gluten. The researchers hope to identify and isolate the hookworm protein to see if it is possible to use it like a drug and not need to use the live parasite - which, over time, can cause excessive blood loss and iron deficiency.

Vitamin D and Diabetes: Epidemiological studies have reported links between low vitamin D status and diabetes. However, other study designs used to identify cause and effect relationships do not indicate that low vitamin D status causes diabetes. Good vitamin D status is important for good health, but it remains to be seen if it helps to prevent diabetes.

Vitamin C could ease muscle fatigue in COPD patients

October 18, 2014
Fiber and Colon Health: For some time, the consumption of foods that provide dietary fiber has been thought to benefit lower intestinal health. This was thought to be due to the bacterial production of a fat component called butyrate that increases when fiber is consumed. New research confirms that butyrate does help to reduce intestinal inflammation and likely reduce cancer risk. The B-vitamin niacin benefits the colon in a similar fashion.
Findings bolster fiber's role in colon health

Omega-3 and Cardiovascular Risk: A person's omega-3 fatty acid status is assessed by measuring the percentage of total fatty acids in red blood cell membranes that are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) - also called the omega-3 index. An omega-3 index of about 8% is considered to be cardioprotective. The average American has an omega-3 index of 4.3% due to relatively low intake of fish on average.

Wheat and Celiac Disease: Gluten represents only part of the protein in wheat. A new study found that people with celiac disease are more likely than people without the disease to have immune system reactions to several of the non-gluten proteins in wheat. Damage to the intestinal cells seen in celiac disease may increase the risk of allergies to food proteins in general.

Walnuts and Prostate Cancer: Walnuts and walnut oil were shown to reduce prostate tumor growth in a mouse model. However, a control diet with the same fatty acid proportions as walnut oil did not reduce tumor growth. For a human to consume a similar amount of walnuts as fed to the mice, it would require almost 500 calories a day of walnuts. Consequently, future research aims to identify the components of walnuts that have this effect.

December 1, 2014
Dietary Saturated Fat vs Carbohydrate: Although accumulating research indicates that saturated fat in the diet does not increase cardiovascular disease risk as previously thought, higher blood levels of saturated fat do seem to increase risk. A recent controlled study found that increasing dietary saturated fat did not affect blood levels of saturated fat. However, increasing dietary carbohydrate raised the fatty acid blood levels associated with an increased risk of diabetes and heart disease.

Sugar and Blood Pressure: A new review claims that excess added sugar intake contributes to the development of hypertension more than sodium. However, this potential association is complicated by the fact that high sugar intake is associated with excess body weight that, in turn, contributes to increased blood pressure. Stay tuned.
More than salt, sugars may contribute to high blood pressure

December 19, 2014
Glycemic Index and Cardiovascular Risk: Low glycemic index diets have been thought to enhance blood glucose control and reduce cardiovascular disease risk. However, a 5-week controlled feeding study found that a low glycemic index diet was no different than a high glycemic index diet in how it affected insulin sensitivity, lipid levels, or systolic blood pressure. This well controlled study indicates that a lower glycemic index diet does not improve cardiovascular risk factors or insulin resistance.

Selenium and Colorectal Cancer: A European study found that adequate selenium status is associated with a reduced risk of developing colorectal cancer, especially in women. But, be careful with selenium supplements. Selenium has a narrow window between levels that are sub-optimal and those that would be considered toxic. The upper limit for selenium is 400 micrograms per day.

Vitamin D and SAD: Seasonal affective disorder (SAD) is a form of depression that usually begins in the fall and continues throughout the winter months. It has been thought that SAD is caused by reduced sunlight exposure and interference with the body's biological clock. There also is evidence that SAD may be due to a drop in vitamin D status caused by reduced exposure to sunlight during fall and winter months.

Vitamin B12 and Oxidative Stress: It seems logical to measure blood levels of vitamin B12 to evaluate a person's B12 status. However, a better measure, blood levels of methylmalonic acid (MMA), indicates how well a B12-dependent chemical reaction is working. Serum MMA increases in B12 deficiency. A new study found that when markers of oxidative stress are increased, serum B12 can be normal even though serum MMA indicates B12 deficiency.

Exercise and Diabetes: Exercise is commonly recommended as part of the treatment for type 2 diabetes. New research found that resistance exercise (strength training) conducted by type 2 diabetics either before or after eating a meal helped to reduce the blood glucose response to the meal. However, exercise after the meal also reduced plasma triglyceride levels more than exercise before the meal.

Lycopene and Kidney Cancer: Renal cell carcinoma is the eighth leading cancer among women. Typically, it is diagnosed at a more advanced stage, making treatment less effective. A study of over 96,000 older women found that those with the greatest intake of lycopene (mostly from tomatoes) had the lowest risk of renal cell carcinoma. This indicates that lycopene in the diet may contribute to prevention of this type of cancer.

Vitamin D and Depression: Young women with lower vitamin D status were more likely to suffer from depression symptoms. This association raises an interesting question, but it does not prove that low vitamin D causes depression. One complicating factor is that the body's production of the form of vitamin D measured to assess vitamin D status (25-hydroxy vitamin D) is accomplished in the liver by an iron-dependent enzyme. Iron deficiency is a known cause of depression that also could reduce 25-hydroxy vitamin D production in the liver.

Fatty Liver and Intestinal Health: When excessive fat accumulates in the liver, it causes nonalcoholic fatty liver disease (NAFLD) that can progress to a more severe form called nonalcoholic steatohepatitis (NASH). New research indicates that this condition is linked with "leaky gut" or increased intestinal permeability that allows microorganisms to to more readily cross the gut wall into the body. Two key nutrients that help to prevent NAFLD and NASH are choline and protein.

Gum Disease and Heart Disease: A new study using a rabbit model found that treatment of gum disease prevented heart disease. These results support epidemiological studies that show links between periodontal disease and heart disease. It appears that the inflammation caused by the gum disease triggers inflammation in the arteries, making them more susceptible to plaque accumulation.

Menstrual Blood Loss and Iron: A study in Finland of 236 women with heavy menstrual periods found that 27% of the women were anemic and 60% were severely iron deficient based on low ferritin levels. One year after treatment with iron supplementation, the anemic women had a significant increase in energy, along with improved physical and social function, and a decrease in anxiety and depression. It took 5 years to get their iron stores to normal levels.

Protein at Breakfast: Another study indicates that consuming a breakfast with 25 to 30 grams of protein helps to moderate blood sugar levels throughout the morning and even helps to moderate the blood glucose response to lunch. This study was conducted with people with type 2 diabetes. Other studies have reported similar results and even have found that a high protein breakfast helps to reduce food cravings later in the day.

Fibromyalgia Triggers: There is little agreement about what causes the chronic pain condition known as fibromyalgia. However, a new study found that one out of four people with fibromyalgia had some physical trauma or infection associated with the start of symptoms. Many other variables, such as iron deficiency, have been linked to fibromyalgia, but there appears to be multiple factors causing the condition.

Iron Status and Diabetes Diagnosis: Hemoglobin A1c (HbA1c) is considered a good blood test to evaluate chronically elevated blood glucose. However, a new review of 12 studies found that iron deficiency with or without anemia causes a false increase in HbA1c. Consequently, it is important to not rely only on HbA1c values without other measures of blood glucose handling in the body. Measures of iron status also appear to be important.
Anemia distorts regular method of diabetes diagnosis and questions its reliability.

Sugar-sweetened Beverages and Fatty Liver: A study of over 2600 people found that regular sugar-sweetened beverage consumption was associated with greater risk of fatty liver disease, particularly in overweight and obese individuals. However, the study did not account for the effects of physical activity on carbohydrate utilization and did not appear to adjust properly for lower protein intake in those who consumed more sugary beverages. Diet soda intake was not associated with measures of fatty liver disease.

Citrus Fruit and Melanoma: An analysis of data from over 100,000 men and women found that those who consumed the most citrus fruit (especially grapefruit) had an increased risk of getting melanoma (skin cancer). This does not mean we should cut citrus fruits out of our diets. Since just about every food has something in it that is bad for us in excess amounts, this is mainly an argument for eating a wide variety of fruits and vegetables and each in moderation.

Stroke Risk and Fish Oil: Arteries, including those providing blood to the brain, are known to stiffen with age. This is thought to be a major reason why stroke risk increases with age. Many aspects of good nutrition appear to contribute to reduced risk of stroke. A new study indicates that one key nutrient that helps to reduce arterial stiffness in older people is the type of omega-3 fatty acids found in fish and algae oils.

Fat, Diabetes, and Fatty Liver Link: Using a diabetic mouse model, researchers found that when excess fat is consumed, some of the fat is converted to a compound called ceramide. When too much ceramide builds up, it causes insulin resistance and possibly diabetes or nonalcoholic fatty liver disease. This research provides potentially new directions in human research for the prevention and treatment of these increasingly common conditions.

Protein and Cardiovascular Health: Several amino acids from protein foods such as glutamic acid, arginine, glycine, cysteine, and histidine are known to modulate blood levels of nitric oxide which relaxes blood vessels and lowers blood pressure. Consequently, it is not too surprising that a recent UK study of about 2000 female twins found that the intake of protein and specific amino acids was associated with reduced arterial stiffness and lower blood pressure. The researchers stated that this beneficial effect was similar in magnitude to established lifestyle risk factors such as physical activity and not smoking.

Trans Fatty Acids and Cardiovascular Disease: German researchers measured trans fatty acid levels in the red blood cells of people being evaluated for cardiovascular disease in a German hospital. They found that those with the lowest trans fatty acid levels had higher rates of cardiovascular mortality and sudden cardiac death. The German diet is low in trans fatty acids from food processing, so most of their trans fatty acids likely were from natural sources like milk products and beef. Since Americans typically have higher dietary and red blood cell levels of trans fatty acid, the general results of this German study may not apply directly to the U.S.
What? Zero Tolerance on Trans Fatty Acid Intake may be Irrational?

Statins and Aging: Statin drugs are used to treat people with cardiovascular disease. However, the use of these drugs for the prevention of cardiovascular disease in people without the condition may be unwise. New research indicates that statin drugs cause cellular changes that are characteristic of the aging process. This may be what causes the often observed statin side-effects of neurological problems, muscle pain, and increased risk of developing diabetes.

Calcium Needs: A new meta-analysis type of study questions current recommendations for high calcium intake to prevent bone fractures. Their results indicate that higher calcium intake does not prevent bone fractures. Too much calcium has potential negative effects on health. It is important to recognize that adequate intake of calcium along with several other nutrients is important for bone health - protein, vitamin D, vitamin C, magnesium, potassium, etc. How much calcium is adequate? More research is needed.

Calcium, Vitamin D, and Cancer: Some studies indicated the possibility that consuming more dietary calcium and/or vitamin D might reduce the risk of developing colon and rectal cancers. However, a newly published study followed over 2000 people for three to five years and found that daily supplementation with 1200 mg of calcium and or 1000 IU of vitamin D had no effect on the development of colorectal polyps (adenomas).
Despite promise, vitamin D and calcium do not reduce colorectal cancer risk

Diabetes, Diet, and Kidneys: Decline in kidney function often develops in people with type 2 diabetes. A preliminary study that followed over 600 type 2 diabetics for about 10 to 15 years found that those who consumed more potassium (based on urine measures) had a lower risk of renal decline than those consuming low levels of potassium. Indicators of sodium intake, however, showed no correlation with measures of kidney function change over time.

Body Fat and Insulin Function: A study of 116 nondiabetic adults ranging in age from 19 to 78 years were tested for insulin sensitivity, a measure of how well insulin facilitates sugar uptake from the blood. Age did not influence insulin sensitivity, but greater levels of fat around the internal organs (visceral fat) and more fat in the liver were both strongly associated with poor insulin sensitivity. Meeting protein needs and avoiding excess calories, especially from carbohydrate and fat, can help to avoid or reduce high levels of visceral and liver fat.

DASH Diet + Fat: The Dietary Approaches to Stop Hypertension (DASH) dietary pattern is high in fruits, vegetables and low fat dairy foods. The diet significantly lowers blood pressure as well as low-density lipoprotein cholesterol (LDL-C). A new study found that a higher fat version of the DASH diet lowered blood pressure to the same extent as the standard DASH diet, but also reduced triglycerides and did not significantly raise LDL-C.

Butter or Vegetable Oils? Substituting high linoleic acid vegetable oils like corn and safflower for butter in the diet has long been thought to reduce blood cholesterol and reduced death, especially from coronary heart disease. However, analysis of previously unpublished data from 50 years ago showed that replacement of saturated fat in the diet with high linoleic acid vegetable oils lowers serum cholesterol but does not translates to a lower risk of death from coronary heart disease or all causes.
Replacing butter with vegetable oils does not cut heart disease risk

May 9, 2016
Abdominal Fat: Obesity often is associated with a generalized increase in inflammation in the body. New research has identified a regulatory molecule produced mainly by visceral fat (internal abdominal fat) that triggers the increased inflammation associated with metabolic disease, insulin resistance, reduced fat mobilization from fat tissues, and an increased risk of death. The subcutaneous fat tissue (just below the skin) is not associated with these risks.
Why is visceral fat worse than subcutaneous fat?

Sodium and Health: A combined analysis of four studies with more than 130,000 participants (about half with hypertension and half without) raises questions about current recommendations for low sodium intake. They found that those with low sodium intake (below 3000 mg/day) had an increased risk of death, myocardial infarction, stroke, and heart failure compared to those with moderate sodium intake. This occurred both in those with hypertension and those with normal blood pressure. However, high sodium intake (above 6000 mg/day) increased death and disease risk only in those who had hypertension.

Diet and Headache: Although the triggers for headaches can vary from one person to another, research has identified some dietary components that make a difference for some headache sufferers. A common trigger for headaches (including migraines) in some people includes regular coffee drinkers not consuming coffee or drinking too much coffee or other caffeine sources. Also, consuming too much MSG, especially in liquid foods like soups appears to affect some susceptible people. Other dietary triggers are less common, but a good elimination diet can help headache sufferers identify offending foods.

Fat and Diabetes: High levels of body fat are associated with an increased risk of developing type 2 diabetes. However, not all people with high body fat develop diabetes and some people with low body fat develop the condition. New research may be uncovering at least part of the puzzle. Some fats in the body are converted into compounds called ceramides. People with higher levels of ceramides in their fat tissue are more likely to develop type 2 diabetes. Finding a way to prevent the accumulation of ceramides may help to prevent type 2 diabetes.

Prediabetes: A large meta-analysis of 53 prospective cohort studies that totaled over 1.6 million participants found that the diagnosis of prediabetes was associated with increased risk of cardiovascular disease and all cause mortality. However, the researchers emphasized that "prediabetes is not a disease but rather a risk factor for future diabetes and cardiovascular disease, and the findings in our study do not mean that pharmacological treatment is warranted in everyone with prediabetes." Rather, the diagnosis may be a good indicator of the need for lifestyle changes in diet and/or exercise.

Vitamin D and Metabolic Syndrome: Based on a study exploring mechanisms in mice, vitamin D deficiency may be a major contributor to the development of metabolic syndrome and fatty liver. Boosting vitamin D status, in mice fed a high fat diet, promoted the health of the intestines, reduced general inflammation in the body, normalized insulin function, and prevented the development of a fatty liver. Human studies are needed to see if the same mechanisms are active in people.

Vitamin C Chemotherapy: There has been some evidence that boosting blood levels of vitamin C by infusing the vitamin intravenously may help to kill cells in some types of cancerous tumors. New research indicates that much of the vitamin C is converted to hydrogen peroxide which can damage cell components in specific types of cancer cells more than it does in normal cells. This kills cancer cells without killing the normal cells.

Whey protein and hypertension: Whey protein, a byproduct of cheese production, is commonly used as a protein source in high protein beverages and other products. When young adults with high blood pressure added a daily drink containing 28 grams of whey protein to their usual diet, it normalized their blood pressure. The whey protein drink had no effect on those with normal blood pressure.

Resveratrol Inhalation: Studies of oral supplementation with the phytochemical resveratrol have shown some anti-aging benefits. A new study used inhaled resveratrol in mice with a genetic defect that causes rapid lung aging. They found that resveratrol inhaled once per month for three months significantly slowed the rate of lung function decline. Although not ready for human use, it appears that resveratrol inhalation is worth testing in people.

B12 Deficiency or Alzheimer's Disease: Alzheimer's disease is diagnosed primarily by observation of progressive impairment of memory and other cognitive functions. Research often links high homocysteine and low vitamin B-12 status with the development of Alzheimer's disease. Since, however, B-12 deficiency causes direct damage to nerve structure and can impair memory, B-12 deficiency (which is easily treated) could be misdiagnosed as Alzheimer's diseas

Potassium and Blood Pressure: Most of us don't consume enough potassium. More and more research indicates that increasing dietary potassium may be more important for healthful blood pressure than reducing sodium. High potassium foods are mainly vegetables, beans, and many fruits. Potatoes are a good source and even potato chips have more than twice as much potassium as sodium.

Iron deficiency and H. Pylori: About half of us are infected with the bacteria Helicobacter pylori that lives in the stomach lining. Most of us have no obvious symptoms, however, research indicates that children, infected with H. pylori have lower iron levels than children previously treated for this bacteria. Since adequate iron is essential for normal brain development and function, it may become more routine to test children for the presence of H. pylori.

Hypertension Diagnosis: It is estimated that about 20 percent of people being treated for high blood pressure have been misdiagnosed and do not need medication. The Canadian Hypertension Education Program recommends that traditional manual measurement of blood pressure (the usual approach for decades) not be used for diagnosis of hypertension. Rather, they recommend using newer automated blood pressure measurement techniques.

Dairy Foods and Health: A study with 897 Irish adults found that those who consumed more total dairy foods had significantly lower body mass index, percent body fat, waist circumference, and waist-to-hip ratio. The study also reported that blood lipid profiles were less favorable when dairy foods were "eaten as part of a low-fat high-carbohydrate dietary pattern." Due to the cross-sectional design, the researchers stressed that more research is needed to clarify the associations they observed.

Celiac Disease and Anorexia Nervosa: A study that included about 18,000 women with celiac disease found that anorexia nervosa often developed before or after the celiac disease diagnosis. Anorexia causes nutrient deficiency conditions (such as iron deficiency, especially in women) which can damage the intestinal structural integrity and increase the risk of developing allergies and celiac disease. Celiac disease can make eating a negative experience that could feasibly promote disordered eating and an eating disorder like anorexia nervosa.

Potassium and Blood Pressure: For many decades the emphasis has been placed on cutting down on dietary sodium to reduce blood pressure. This recommendation has met with some degree of scientific controversy. However, as emphasized in a recent review article, there is substantial agreement that adequate potassium intake is an important contributor to normal blood pressure. Foods high in potassium (in decreasing order of potassium per common serving) include potatoes, prunes, carrots, most leafy greens, beans, tomato juice and sauces, yogurt, sweet potatoes, orange juice, and bananas. Fun fact: regular potato chips have more than twice as much potassium as sodium.

Diabetes and Renal Health: High blood glucose levels in diabetes are known to contribute to progressive kidney damage (diabetic nephropathy). A recent study of diabetic mice found that a low carbohydrate "ketogenic" diet reversed diabetic nephropathy in two months. The researchers plan to explore how their observations may be tested further in humans.

Oats and Gluten: A new systematic review of 28 studies concluded that pure oats do not cause reactions in people with celiac disease. However, one complication is that oats are easily contaminated with gluten-containing grains such as wheat, rye, or barley at many stages of production, handling, and processing.
Oats appear safe for patients with celiac disease

Coffee and Prostate Cancer: A four-year Italian study of almost 7000 men age 50-plus, found that the risk of prostate cancer was lower in men who consumed more coffee. Although some of the headlines on coverage of this study imply that there is something special about Italian coffee, the researchers followed up their epidemiological study with cell culture research using prostate cancer cell lines and concluded that the main contributor to the reduced risk was caffeine.

Stress and Intestinal Function: In response to four days of intensive military training that was both physically and psychologically demanding and stressful, soldiers experienced an increase in intestinal permeability, inflammation, and a change in the relative amounts of various bacteria in their lower intestine. These changes also may occur in athletes during periods of intensive training and would be expected to increase the risk for a number of problems, including increased susceptibility to illness and infection, and, if chronic, increased disease risk.

Vitamin D and Asthma: Some epidemiological studies found that low vitamin D status is associated with increased rates of asthma. However, a new large study on more than 100,000 individuals identified those with genetic variations associated with vitamin D status and found that there was no significant association between vitamin D status and the incidence of asthma. Though not likely to be a cure for asthma, maintaining good vitamin D status is important for many other health-related reasons.

Statin Use in Older Adults: Researchers analyzed data from 2,867 people, age 65 and older with high blood pressure and no evidence of arterial plaque accumulation. About half of these individuals were taking the statin drug pravastatin. After six years, the results indicated that there was no difference in mortality between those taking the statin drug and those not taking it. Of some concern, among those 75 and older, there was a nonsignificant trend toward increased all-cause mortality in those taking pravastatin.

Vitamin A and Diabetes: New research indicates that a form of vitamin A plays a key role in the process that triggers pancreas beta-cells to release insulin when needed. Although the researchers do not indicate that high dose vitamin A can treat type 2 diabetes (due to toxicity concerns), they do think that their research may lead to the discovery of other, less toxic, chemicals that can trigger the same cell receptors affected by vitamin A.

Type 2 Diabetes and Fatty Liver: Non-alcoholic fatty liver disease (NAFLD) is an abnormal accumulation of fat in the liver that can damage liver structure and function over time. NAFLD is more common in people with type 2 diabetes. Good nutrition can help to prevent or treat NAFLD. Maintaining normal vitamin E and D status may help. Also, adequate intake of protein and choline helps to move fat out of the liver. Eggs are a rich source of choline as well as protein.

Diabetes in Asia: Many people with certain types of Asian ancestry are at increased risk of developing type 2 diabetes. This is often the case for Asians who are not overweight by typical standards, but they have excess body fat - sometimes called normal weight obesity. Consequently, more specific standards are needed for these populations, along with regular screening for diabetes or prediabetes.

Iron Status and Heart Disease: In 1981, the theory was proposed that higher iron status increases the risk for coronary artery disease. A very large new study that accounted for genetics along with iron status found just the opposite - higher iron status reduces coronary artery disease risk. Up until now, less well-designed studies both supported and refuted the theory. This new study is the most conclusive to date and should relegate the 1981 theory to the history books.

Non-anemic Iron Deficiency in Young Women: Young women are often screened for Iron deficiency anemia to assess iron status. However, a recent study found that this may miss almost ten percent of women age 12 to 21 years who have iron deficiency without anemia. The researchers recommend that females be fully evaluated for iron status (not just anemia) at age 16 or approximately three years after the start of menstruation.

Healthy Diet: Many studies have been questioning the long-standing recommendation to reduce dietary fat and especially saturated fat. Newly published research studied the diets and mortality of over 135,000 people across five continents. Based on data from about 7.5 years, the researchers found that a diet with a moderate intake of fat, fruits and vegetables along with avoidance of high carbohydrate intake was associated with lower risk of death. Lower total dietary fat and saturated fat was associated with increased risk of heart attack or death due to cardiovascular disease.

Extremely High HDL: A study conducted in Denmark followed more than 100,000 adults for an average of six years. They found that men with the lowest risk of death had HDL levels at 73 mg/dL and women with the lowest risk had HDL at 93 mg/dL. However, mortality risk increased in those with unusually high HDL levels (over 97 for men and above 135 for women). Since there were few people with such high HDL levels, the researchers suggest that more research is needed to confirm their observations.

Vitamin D and Rheumatoid Arthritis: In addition to pain from joint inflammation, people with rheumatoid arthritis can experience neurological pains not relieved by the medications commonly used for this condition. A new study found that rheumatoid arthritis patients who experienced this neuropathic pain were very likely to have low vitamin D status. Although iron status was not measured, 80 percent of those with this problem were women. It is possible that vitamin D and/or iron supplementation may help to prevent this neuropathic pain associated with rheumatoid arthritis in some people.
