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 disease.

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.

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.

There has been plenty of research supporting light to moderate alcohol consumption having potential health benefits. However, some caution is indicated by a new study that followed 2609 men for about 20 years and found that those who consumed alcohol most frequently (even moderately) had a significantly greater risk of dying from a stroke.

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.

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.

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.

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.

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.

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.

Breakfast and Type 2 Diabetes: When people with type 2 diabetes consumed a 700 calorie breakfast (with over 50 grams of protein), a 600 calorie lunch (40 grams of protein), and a 200 calorie dinner (22 grams of protein), they had much better blood glucose control throughout the day than when they had a 200 calorie breakfast, the same lunch, and a 700 calorie dinner. It appears that a good high protein breakfast works best for diabetics.

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.

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.

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.

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.

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.

Carbohydrate Tolerance: A research study showed that men with a prediabetes glucose tolerance level handled a high carbohydrate meal better early in the day than they did at the end of the day. Results were similar in men with normal glucose tolerance, but these results were not statistically significant.

Gut Microbes: New research questions the applicability of the results of studies transplanting lower intestinal contents from one animal into another animal that was raised in a bacteria-free environment. They found that animals fed normally in a normal environment responded to gut microbiota transplants very differently than bacteria-free mice.

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.

Milk fat and diabetes risk: A study that followed almost 4000 people for 20 years found that those who consumed the greatest amounts of a trans fatty acid (trans-palmitoleate) naturally present in milk fat had better insulin sensitivity and were less likely to develop diabetes. Based on these results, skim milk may not be the best option.

Sugars and Fats: When the diet is high in carbohydrate and calories, the liver converts more sugar to fatty acids. A two-year intervention study that encouraged six to eight year old children to improve their overall diet and increase exercise, found that the children had a decrease in sugar to fat conversion.

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.

Viral Cause of Celiac: A new study makes the case that a major trigger for celiac disease may be the effects of the body's immune response to a normally innocuous virus (reovirus). There is still much to learn about this and how immune health may play a role.

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.

Coffee and Prostate Cancer: An 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.
