Are Vitamin Drinks a Bad Idea?

ID-10020546The vitamins and minerals are in the news again, with all this being related to their addition to sports drinks, water and juices. Scientists suggests that consumers might be ingesting higher than necessary (and sometimes potentially harmful) amounts. When consumed in excess, water-soluble vitamins like B and C are in the urine, but fat soluble-vitamins including A, D, E and K, accumulate in tissues, posing potential risks. Some people (for example, pregnant or lactating women) will require additional vitamins and minerals, but for the majority of the population, these nutrients should be primarily acquired through daily diet. This discussion extends to antioxidants and the lack of information on the long-term supplementation effects. Scientists state that it is impossible to consume too much from foods but the exposure through supplementation may be too great. How do you counsel your patients about healthy diet and vitamin/mineral/antioxidant rich foods? For those who require supplementation, what are your typical recommendations?

How Vitamin D May Fight Colon Cancer

ID-100130112New observational research performed at Dana Farber Cancer Institute, Brigham and Women’s Hospital and Harvard Medical School was just published in the journal Gut.  Researchers have associated higher levels of vitamin D with a reduced risk of colon cancer, stating that the higher the levels in the blood, the less is the likelihood of developing malignant tumors in the colon. The authors discuss how vitamin D boosts immunity in cancer as well as any other type of infection leading to greater number of T cells which target tumor cells and limit their growth. When did you have your vitamin D level check last?

Blueberries May Lower Blood Pressure

ID-10069469In a new study from the Journal of the Academy of Nutrition and Dietetics, researchers found eating a cup of blueberries a day has a moderate effect on lowering blood pressure. In this randomized, double-blind, placebo-controlled study of 40 postmenopausal women, those women who ate a cup of blueberries a day for 8 weeks saw an average decrease in systolic blood pressure by 5.1 % and a 6.3 % decrease in diastolic blood pressure. The levels of nitric oxide, responsible for relaxing blood vessels, were increased in the group who consumed blueberries while there was no significant change in the placebo group.Researchers recommend adding blueberries to your diet to help lower blood pressure. What are some of the reasons and best ways you incorporate blueberries into your daily diet?

Higher-fiber diet linked to lower risk of death

ID-100232441The American Journal of Epidemiology is encouraging individuals to increase their daily dietary fiber intake. Dr. Yang of the Shanghai Cancer Institute in China, collected data from 17 previous studies and reported people who ate the greatest amount of fiber were 16 % less likely to die than those who ate the least amount. The more fiber people ate the less likely they were to die from any cause. Eight of these studies proved increasing dietary fiber by 10 grams a day would decrease risk for any cause of death by 10 %. Researchers say fiber-rich foods lower the risk of chronic diseases by lowering blood pressure, cholesterol, glucose, insulin and reducing inflammation. According to the U.S. Department of Agriculture women should consume 25 grams a day and men about 38 grams a day.It has been reported that the U.S population only consumes half the recommended goal. It is important to remember when increasing your daily fiber intake to do it slowly and drink plenty of water. Fiber-rich foods to add to your daily diet include whole grains, fruits, vegetables and legumes. What are some of your favorite recipes/suggestions that incorporate these foods/ingredients?

In search of a personalised diet

ID-100123942A new study lead by BBC Science and obesity experts explains every person has different eating habits and specific diets are needed for each person based on their hormones, genes,cognitive behavior etc. Instead of following a standard diet it is important to focus on your eating habits first to develop a diet specific for you. Scientists from Oxford and Cambridge followed and observed eating trends of 5 dieters for three months in their homes. The study looked at three types of over eaters, feasters, constant cravers and emotional eaters. The study found diets are based off habits. The feasters, people who have a hard time stopping eating, have a problem with their gut hormone balance. Constant cravers, people that are always hungry, have certain genes that disrupt the signals sent to the brain so they do not know when they are full. Emotional eaters eat when they feel anxious or stressed which is a habit they have developed. Overall, feasters lost the most weight and constant cravers had the hardest time losing weight. Dieters learned what type of eater they were and experts came up with plans to help them change their eating habits and practice the best diet for them. Although personalized diets are a new trend, experts say there is a lot of potential to help people lose more weight once they know more about their own body and how it affects their eating habits. Depending on the type of eater you are determines the type of diet you should try.

Would a personalized diet help people to lose weight?

Tea, citrus products could lower ovarian cancer risk, new research finds

chinese-green-tea-pot-and-cups-100204803According to new study from the Brigham and Women’s Hospital and Harvard Medical School, consuming tea and citrus juices could correspond to a lower risk of developing ovarian cancer. This was the first large-scale study to determine the role of flavanoids on ovarian cancer, and followed 172,000 patients over three decades. The research team found that women who consumed flavonols and flavanones, which are two sub-types of flavanoids, experienced much less of a risk of developing epithelial ovarian cancer. Since these flavanoids are found in tea and citrus juices and fruits, it is fairly easy to incorporate them to get the associated benefits. This was a promising find, as roughly 20,000 women are diagnosed with ovarian cancer in the United States each year and it also happens to be the fifth leading cause of death from cancer among women. What other dietary sources of flavanoids do you recommend to your patients for health benefits?

Food Scores, a New Web Service, Ranks Grocery Items on Ingredients and Nutrition

nutritious-apple-with-health-facts-10055103On Monday, The Environmental Working Group launched a new program known as the Food Scores Database, which encompasses the nutritional values of over 80,000 foods you may find in your local supermarket. Each product has been rated on a scale from 1 to 10, with 1 being the most nutritious. The current push from consumers to know what is in packaged foods or how heavily processed they are, has helped to fuel this project. Also included, is product information from food companies and research conducted by The Environmental Working Group themselves, regarding pesticides, additives, preservatives, and dyes. Food Scores will soon be available as a phone app and allow consumers to scan product bar codes. Thus far, the scoring system has faced ridicule from the Grocery Manufacturers Association, but the founder of the environmental group trusts that the general public will both embrace and utilize this new program. As your patients become more health conscious, how do you teach them to evaluate the quality of their food? What other programs are available at this time to help consumers purchase healthier choices?

Animal Study Shows High-Fat Diet is More Harmful to Males than Females

classic-hamburger-sandwich-100188767Based on a new study published in the journal Cell Reports, the biological response to high-fat diet in male and female brains are not the same. According to the study, the brains of male mice became inflamed and their heart were damaged after given a steady high-fat meals, while nothing of that happened to the female mice. Interestingly, female brains have been found to produce anti-inflammatory chemicals that kept them from getting harmed by high-fat diet. However, further studies are still needed to prove these results on humans. How much do your dietary recommendations vary in men and women? What are your thoughts about this research?

Sugar Accelerates Aging Process as Much as Smoking Does, U.S. Study Says

canned-10080125According to a new study published in the American Journal of Public Health, drinking sodas has been found to be linked to a fast aging process. By analyzing stored DNA from more than 5,300 healthy Americans in the National Health and Nutrition Examination Survey (NHANES) from some 14 years ago, researchers have revealed that drinking a 20-ounce bubbly beverage every day is linked to 4.6 years of additional aging. Interestingly, these results are similar to those that are linked to smoking. However, the cause-effect relationship has not been established yet. The studies regarding to the danger of sodas are continuously growing, what are your thoughts about the best way to decrease their consumption?
