The bottom line was that eating a high plant diet, based around the healthy Mediterranean vegetarian patterns, was very beneficial for diabetics.
“The diet quality findings weren’t any surprise, ‘but isn’t it great to have more science to prove what we think makes a lot of sense?”
Dr Melinda Maryniuk, RD, director of clinical education programs at Joslin Diabetes Center in Boston, June 2014.
The data reviews of the Nurses’ Health Study I and II/Health Professionals Follow-up Study (148,479 people) found:
- Regardless of body size or exercise, improving the diet was linked with lower levels of diabetes
- Increasing fruit, vegetable, nuts, good quality oils showed a 9% lower risk of diabetes incidence
- Dropping the quality of the diet showed an 18% increase in risk
- Extra servings of extra-virgin olive oil lowered cardiovascular risk (on the Framingham risk score)
“Such whole-grain diets have invariably been associated with a reduced risk of diabetes and cardiovascular disease in cohort studies… Olive oil has the evidence to put it in the ‘healthy’ category, from trials such as PREDIMED, which found a 30% cardiovascular risk reduction and 40% diabetes risk reduction with extra olive oil in a Mediterranean diet compared with a low-fat diet… these are foods that, I think, displace foods which are not so healthy, the saturated fat foods, the animal products, and the highly refined carbohydrates”
