Do Vegetables and Fruits Prevent Disease?

Switching to the paleo diet often leads to increased vegetable and fruit consumption

Switching to the paleo diet often leads to increased vegetable and fruit consumption

Potential answers are in the American Journal of Clinical Nutrition (2012).  I quote:

For hypertension, coronary heart disease, and stroke, there is convincing evidence that increasing the consumption of vegetables and fruit reduces the risk of disease. There is probable evidence that the risk of cancer in general is inversely associated with the consumption of vegetables and fruit. In addition, there is possible evidence that an increased consumption of vegetables and fruit may prevent body weight gain. As overweight is the most important risk factor for type 2 diabetes mellitus, an increased consumption of vegetables and fruit therefore might indirectly reduces the incidence of type 2 diabetes mellitus. Independent of overweight, there is probable evidence that there is no influence of increased consumption on the risk of type 2 diabetes mellitus. There is possible evidence that increasing the consumption of vegetables and fruit lowers the risk of certain eye diseases, dementia and the risk of osteoporosis. Likewise, current data on asthma, chronic obstructive pulmonary disease, and rheumatoid arthritis indicate that an increase in vegetable and fruit consumption may contribute to the prevention of these diseases. For inflammatory bowel disease, glaucoma, and diabetic retinopathy, there was insufficient evidence regarding an association with the consumption of vegetables and fruit.

It bothers me that vegetables and fruits are lumped together: they’re not the same.

The paleo diet is unfairly characterized as meat-centric. It can certainly provide beaucoup vegetables and fruits. Diabetics should be careful which ones they choose, to avoid spikes in blood sugar.

New Type 2 Diabetics Not Hurt With Moderate Fruit Consumption

Brian’s Berry Breakfast: simply strawberries and walnuts

…according to an article in Nutrition Journal. (BTW, Shelby Hughes,with Type 1 diabetes, mentioned in a recent interview that she eats a fair amount of fruit.) The Nutrition Journal study participants were newly diagnosed type 2 diabetics. This is interesting research because we’ve often assumed that the sugar in fruits would raise blood sugar too high, leading to recommendations to avoid fruits, or at least limit them to one piece daily.

Of course, fruit in an integral component of most paleo diets.

The Well blog at the New York Times covered the story.  You’ll likely find the comments illuminating.  Also see this Diabetes Self-Managment article. I’ll read the original research report when time allows.

Fruit May Not Sabotage Control of Type 2 Diabetes

…according to an article in Nutrition Journal.  Fruit is a prominent component of the paleo diet.  It can be good for us, containing phytonutrients, fiber, etc.  But fruit has the potential to increase blood sugars, too, which may be harmful over the long run.  So whadda you do?

Researchers took newly diagnosed type 2 diabetics and split them into two groups. One group was told to eat at least two pieces of fruit daily, the other was told to eat no more than two pieces.

The researchers conclusions: 

A recommendation to reduce fruit intake as part of standard medical nutrition therapy in overweight patients with newly diagnosed type 2 diabetes resulted in eating less fruit. It had however no effect on HbA1c, weight loss or waist circumference. We recommend that the intake of fruit should not be restricted in patients with type 2 diabetes.
