Fruit consumption and risk of type 2 diabetes: results from three prospective longitudinal cohort studies.
A recent study published in the British Medical Journal looked at the diets of more than 187,000 people in the US. People eating three servings of fruit per week, particularly blueberries, apples and grapes had a reduced risk of developing type-2 diabetes. The researchers believe this is because fruits contain high levels of anthocyanins, which have been shown to enhance glucose uptake in mice. However, when researchers looked at the effects of fruit juice consumption, they found a slightly increased risk of type-2 diabetes. The study recommended that replacing weekly fruit juice consumption with whole fruits could bring health benefit. What are your thoughts on this study? What do you recommend as part of a balanced and healthy diet?

Current Biology published a study regarding the best way to store fruits and vegetables to obtain the most benefit. The study found fruits and vegetables follow a 24-hour plant clock. Food crops can alter the internal chemical level throughout the day in order to ward off pests. Storing fruits and vegetables under the light-dark cycles helps them to preserve more nutrients. Glucosinates, a chemical with anti-cancer property is produced by cabbage in the day; refrigerated cabbage on the opposite produced less glucosinates. Further tests revealed many other crops (e.g., lettuce, spinach, courgettes, sweet potatoes, carrots and blueberries) also follow the same light-dark cycle. Please share your thoughts on the result of this study. How do you typically store your fruits or vegetables?

A recent publication in the Journal of the Science of Food and Agriculture evaluated the amount and nutritional value of canned vs. frozen produce, concluding that it is almost the same, if not better. Canned food can lose some of its nutrients, specially water-soluble vitamins such as vitamin B and C. However, being protected from oxygen,it retains nutrient stability.Fresh fruit and vegetables, although starting with higher vitamin and nutrient content, tend to lose some during shipping and processing.
What are your thoughts about these findings? How often do you chose fresh fruits over canned ones? How often does your fresh produce travel long distance to get to you?

A study published in the Nutrition Journal concluded that patients consuming a diet of two or less pieces of fruit daily showed no difference in weight loss or HbA1C versus those who did not restrict their fruit intake. The study consisted of 63 patients who were newly diagnosed with type 2 diabetes and wanted to see how fruit restriction affected glycemic control. Patients were randomized to a high-fruit or low-fruit diet in this parallel design, open-label trial. What dietary changes do you recommend in patients with type 2 diabetes?

A clinical report published in the journal Pediatrics discusses the health and environmental advantages and disadvantages of organic foods. Itdefines the term “organic”, reviews food-labeling standards and farming practices, discusses environmental implications of conventional vs. organic techniques. The reportstates that eating organic fruits and vegetables do not provide additional nutrition in comparison with the conventionally grown foods, butcontain fewer pesticides related to a variety of illnesses. The report recommends that parents should aim to provide their families a diet rich in fruits and vegetables. What are your thoughtsand recommendations on organic/local/sustainably grown foods?

A recent study from Boston University found that eating two or three servings of cherries reduced the risk of gout attacks. Extra benefit was not seen with further consumption. Cherries have been suggested to be natural inhibitors of enzymes which cause inflammation. What foods do you currently recommend for your patients with gout?

Could apples help you keep your blood sugar in check? A new study published in PLoS ONE, found a compound called ursolic acid, which is naturally found in apples, helped mice to gain less weight and to keep their blood sugar levels more stable. What dietary and lifestyle recommendations do you make to your patients to help them maintain a healthy weight and blood sugar?
