Fruit form affects glycemic response after meals

Health Care Comments Off

The beneficial effects of fruits and vegetables on health are well-established. Reiterating this, a new study from Singapore published February 15, 2017 in the Journal of Nutrition Health and Aging, the journal of the European Union Geriatric Medicine Society says that fruits are a valuable source of nutrient regardless of the form of delivery in elderly and young adults.

The study evaluated the effect of two fruits, guava and papaya in two different forms i.e. bite size and puree on glycemic response (GR) in 19 healthy participants comprising of nine elderly and 10 young adults. The study subjects consumed glucose (reference food) on three occasions and test fruits (guava bites, guava puree, papaya bites, and papaya puree) on one occasion each. All fruit forms and types studied were found to be low glycemic index (GI) (guava bites: 29; papaya bites: 38; papaya puree: 42; guava puree: 47). The glycemic response was significantly greater in the elderly compared to that observed in the young participants

The study concluded that fruit form influences glycemic response in the elderly and young adults; however, all fruit types and forms studied were found to be low GI.

The American Heart Association (AHA) recommends filling at least half your plate with fruits and veggies in order to make it to the recommended 4-5 servings of each per day. The American Diabetes Association (ADA) also encourages patients with diabetes to choose a variety of fiber-containing foods, such as fruits, vegetables and whole grains. Fruits and vegetables contain vitamins, minerals, phytochemicals, and antioxidants and are low in calories. Those with the most color – dark green, red, yellow, and orange – have the most nutrients. All seven colors and six tastes should be included in diet.
