Healthy Fruits – Healthy Vegetables:Brooke Douglas RD Tells All

Brooke Douglas RD is back with her first of the month post, this time telling us about healthy fruits and healthy vegetables.  Don’t miss a word.

Almost Everything You Ever Wanted to Know About Fruits and Vegetables

Research shows that people who eat even 2½ cups of fruits and vegetables a day have only half the cancer risk of those who eat less than one cup a day.  Hundreds of studies show that increased fruit and vegetable consumption may also help prevent heart disease, stroke, hypertension, birth defects, cataracts, diabetes, obesity and other serious conditions.

Healthy Fruits and vegetables are nutritional powerhouses which:

  • Are excellent sources of vitamins and minerals and contain disease fighting fiber
  • Contain antioxidants and phytochemicals
  • Are virtually fat-free (exceptions: coconut, olives & avocado) and cholesterol-free
  • Are helpful in weight management, due to their high-fiber, high-water, and low-fat content

Vitamins and minerals: Are essential in maintaining the health of the brain, heart, bones, teeth and nerves; making/repairing red blood cells; regulating body’s balance of fluids; and in other vital functions.

Many healthy fruits and vegetables are particularly good sources of vitamins A, C, E and K, some B vitamins, and many important minerals needed for healthy bodies.  Beta-carotene and related compounds called carotenoids are converted by the body to Vitamin A. Carotenoids are found in high concentrations in carrots and other orange and yellow vegetables and fruits such as winter squash and cantaloupes.  Dark green, leafy vegetables, such as spinach, kale, broccoli, and other members of the cabbage family, also contain high concentrations of carotenoids.

Dark green vegetables are also excellent sources of folic acid (a B vitamin needed during pregnancy to reduce the risk of neural defects in the fetus), Vitamins E and K, and minerals such as calcium, magnesium, manganese, iron, and potassium.  Many fruits are also a good source of minerals, such as chromium (grapes), iron (cherries), manganese (pineapple), and potassium (apricots, bananas, orange juice, peaches and prunes).

Citrus fruits are good sources of Vitamin C, as is the family of plants that includes tomatoes, red and green peppers, potatoes, and eggplant.  Other good sources of Vitamin C include papayas, strawberries, kiwis, cantaloupe, and the cabbage family, including broccoli, cauliflower and Brussels sprouts.

While there is overlap in the vitamins/minerals supplied by fruits and vegetables, you need a wide variety of colorful healthy fruits and vegetables to fully benefit from the various nutrients they contain.

Antioxidants: Disease-fighting compounds found in many foods, especially healthy fruits and vegetables. Antioxidants neutralize free radicals (compounds that damage cells and lead to cardiovascular disease, cancer, cataracts, premature aging, and impaired immunity.)  Antioxidants include vitamins A, C, and E; beta carotene, minerals (selenium, copper, zinc, and manganese) and some of the phytochemicals.

 

Phytochemicals: From plants, “plant chemicals” are recognized as powerful disease-fighting compounds. Fruits and vegetables contain thousands of different phytochemical compounds. Categorized as carotenoids, flavenoids (compounds that give flavor/colors to fruit/veg), and other compounds, such as allicin, indoles, lycopenes, lutein, and phenols.  Scientists studying phytochemicals are finding an impressive range of health benefits.

Color & Examples Phytochemical Examples Potential Benefits
Red: apples, cherries, strawberries, watermelon, beets, red peppers, radicchio, tomatoes Lycopene, anthocyanins Maintain memory function, heart health urinary tract health; reduce blood pressure, fight infections, and reduce risk of some cancers
Orange/yellow: apricots, mangos, oranges, peaches, pineapple, cantaloupe, carrots, corn, winter squash Carotenoids, bioflavonoids Maintain health of heart, eyes, and immune system, slow aging, and reduce risk of some cancers
Green: leafy greens, asparagus, broccoli, green beans, peas, spinach, honeydew, kiwi, avocados Lutein, indoles, carotenoids Improve vision, strengthen bones and teeth, and reduce risk of some cancers
Blue/purple: blueberries, blackberries, purple grapes, plums, eggplant, purple cabbage Anthocyanins, phenolics, resveratrol Facilitate healthier aging, enhance memory function, urinary tract health and cardiovascular health and reduce risk of some cancers
White/tan/brown: onions, garlic, cauliflower, turnips, mushrooms, potatoes, bananas, pears, dates Allicin, quercetin, sulphoraphane Improve heart health, maintain healthy cholesterol levels, and reduce risk of some cancers

 

Not all foods listed above, even within the same group, have the same health benefits.  Foods with the same phytochemicals may contain different concentrations of the phytochemicals, and the compounds may be absorbed differently.  Even different varieties of foods within the same category (such as different varieties of apples or lettuce) may contain widely varying concentrations and kinds of phytochemicals.  However, those darker in color usually contain higher concentrations.  So think “more color and more variety” in making your selections!
