Vegetables, fruits, and disease

Cardiovascular disease

There is an evidence that a diet rich with fruit and vegetable can lower danger of heart condition as well as stroke.

A meta-analysis of 469551 persons found that a high intake of fruit and vegetable is associated with a reduced death risk from cardiovascular disease, with an average reduction in risk of 4% for each extra serving per day of fruit and vegetable.

The largest and longest and biggest study till date, done as part of the Harvard based Nurses’ Health Study and Health Professional Follow up Study, included around 110,000 men and women whose health and dietary pattern were followed for 14 years.

Blood pressure

The Dietary Approaches to prevent Hypertension (DASH) study examined the effect on vital sign of a diet that was rich in fruits, vegetables, and low-fat dairy products which restricted the amount of saturated and total fat. The researchers and doctors found that people with high blood pressure who followed this diet reduced their systolic blood pressure (the upper number of a blood pressure reading) by around 11 mm Hg and their diastolic vital sign (the lower number) by aroung 6 torr —as very much like medications are able to do.

A randomized trial referred to as the Optimal Macronutrient Intake Trial for Heart Health (OmniHeart) showed that this fruit and vegetable-rich diet lowered vital sign even more when a number of the carbohydrate was changed with healthy unsaturated protein or fat.

In 2014 a meta-analysis of clinical trials and observational studies found that consumption of a vegetarian diet was related to lower vital sign.


Numerous early studies revealed what seemed to be a robust link between eating fruits and vegetables and protection against cancer. Unlike case control studies, cohort studies, which follow big group of initially healthy individuals for years, generally provide more reliable information than case-control studies because they don’t rely on information from the past. And, in general, data from historic studies have not consistently shown that a diet rich in fruits and vegetables prevents cancer.

For example, over a 14-year period within the Nurses’ Health Study and therefore the Health Professionals Follow-up Study, men and ladies with the very best intake of fruits and vegetables (8+ serving a day) were just as likely to have developed cancer as those who ate the less daily servings.


Some research looks specifically at whether individual fruits are related to risk of type 2 diabetes. While there is not an plenty of research into this area yet, preliminary results are compelling.

A study of 65000 women in the Nurses’ Health Study, 85104 women from the Nurses’ Health Study II, and 36173 men from the Health Professionals Follow-up Study—who were free of major chronic diseases—found that greater consumption of whole fruits—especially blueberries, grapes, and apples—was related to a lower risk of type 2 diabetes. Another important finding was that greater consumption of fruit crush was related to a better risk of type 2 diabetes.

Additionally a study of over 70,000 female nurses aged 38-63 years, who were freed from disorder , cancer, and diabetes, showed that consumption of green leafy vegetables and fruit was associated with a lower risk of diabetes. Research also indicated that intake of fruit juices could also be related to an increased risk among women.

A study of over 2,300 Finnish men showed that vegetables and fruits, especially berries, may reduce the danger of type 2 diabetes.


Result from the Nurses’ Health Study and the Health Professional’s Follow-up studies shows that women and men who increased their intakes of vegetables and fruits over 24-year period were more likely to have weight lost than those who ate the same amount or those who decreased their intake.

cauliflower, Berries, soy, pears and apples were associated with weight loss while starchier vegetables like peas, corn, and potatoes were linked with weight gain. However, confine mind that adding more produce into the diet won’t necessarily help with weight loss unless it replaces another food, like refined carbohydrates of light bread and crackers.


Eating vegetables and fruits can also keep your eyes healthy and clean, and may help prevent two common aging-related eye diseases cataracts and macular degeneration which afflict millions of Americans over age 65. zeaxanthin and Lutein, in particular, seem to reduce risk of cataracts.
