Vegetables and fruits are an important part of a healthy diet, and variety is as important as quantity.
No single fruit or vegetable provides all of the nutrients you need to be healthy. Eat plenty everyday
A diet rich in vegetables and fruits can lower blood pressure, reduce risk of heart disease and stroke, prevent some types of cancer, lower risk of eye and digestive problems, and have a positive effect upon blood sugar which can help keep appetite in check.
Eat a variety of types and colors of produce in order to give your body the mix of nutrients it needs. Try dark leafy greens; brightly colored red, yellow and orange vegetables and fruits; and cooked tomatoes.
Eat more vegetables and fruits each day

1. Keep fruit where you can see it. That way you’ll be more likely to eat it.
2. Explore the produce aisle and choose something new. Variety is the key to a healthy diet.
3. Skip the potatoes. Choose other vegetables that are packed with more nutrients and more slowly digested carbohydrates.
4. Make it a meal. Try cooking new recipes that include more vegetables. Salads and stir fries are two ideas for getting tasty vegetables on your plate.

Vegetables, fruits, and disease

Cardiovascular disease
There is compelling evidence that a diet rich in fruits and vegetables can lower the risk of heart disease and stroke. The largest and longest study to date, done as part of the Harvard-based Nurses’ Health Study and Health Professionals Follow-up Study, included almost 110,000 men and women whose health and dietary habits were followed for 14 years.
The higher the average daily intake of fruits and vegetables, the lower the chances of developing cardiovascular disease. Compared with those in the lowest category of fruit and vegetable intake (less than 1.5 servings a day), those who averaged 8 or more servings a day were 30 percent less likely to have had a heart attack or stroke.

Although all fruits and vegetables likely contribute to this benefit, green leafy vegetables such as lettuce, spinach, Swiss chard, and mustard greens; cruciferous vegetables such as broccoli, cauliflower, cabbage, Brussels sprouts, bok choy, and kale; and citrus fruits such as oranges, lemons, limes, and grapefruit (and their juices) make important contributions.
When researchers combined findings from the Harvard studies with several other long-term studies in the U.S. and Europe, and looked at coronary heart disease and stroke separately, they found a similar protective effect: Individuals who ate more than 5 servings of fruits and vegetables per had roughly a 20 percent lower risk of coronary heart disease and stroke, compared with individuals who ate less than 3 servings per day.

Blood pressure
The Dietary Approaches to Stop Hypertension (DASH) study (4) examined the effect on blood pressure of a diet that was rich in fruits, vegetables, and low-fat dairy products and that restricted the amount of saturated and total fat. The researchers 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 about 11 mm Hg and their diastolic blood pressure (the lower number) by almost 6 mm Hg—as much as medications can achieve.
A randomized trial known as the Optimal Macronutrient Intake Trial for Heart Health (OmniHeart) showed that this fruit and vegetable-rich diet lowered blood pressure even more when some of the carbohydrate was replaced with healthy unsaturated fat or protein.
