The nutrients found in the above fruits and vegetables have a significant impact on our health.
Quercetin, which is found in apples, onions and other citrus fruits, not only prevents LDL cholesterol oxidation, but also helps the body cope with allergens and other lung and breathing problems.
Ellagic acid, which is mainly found in raspberries, strawberries, pomegranates, and walnuts, has been proven in many clinical studies to act as an antioxidant and anticarcinogens in the gastrointestinal tract. This nutrient also has been proven to have an anti-proliferative effect on cancer cells, because it decreases their ATP production.
The best-known of the carotenoids, beta-carotene, is converted into vitamin A upon entering the liver. Although being known for its positive effects on eyesight, it has also been proven to decrease cholesterol levels in the liver.
Clinical studies have proven that lycopene, mainly found in tomatoes, may decrease the risk of prostate cancer, as well as protect against heart disease. Lutein, which is found in blueberries and members of the squash family, is important for healthy eyes. However, it does support your heart too, helping to prevent against coronary artery disease.
Along with the above stated nutrients, there are even more nutrients found in fruits and vegetables that provide a great deal of support to our body. Almost everyone has heard of vitamin C, which keeps our immune system strong; speeds wound healing, and promote strong muscles and joints. This nutrient is scattered throughout the spectrum of fruits, but commonly associated with oranges and other citrus fruits. Potassium, which is the nutrient most Americans are deficient in, does great things for our hearts, and lowers blood pressure.
Another good food component many people don't get enough of if fiber, found in fruits, vegetables, and whole grains.
Flavonoids, which include anthocyanins, flavones, isoflavones, proantocyanidins, quercetin and more, are found almost everywhere. They are responsible for the colors in the skins of fruits and vegetables and help to stop the growth of tumor cells and potent antioxidants. They also can reduce inflammation.
Beta-glucan, found in mushrooms, stabilizes and balances the body's immune system by supporting white blood cells. EGCG is found in tea and has been shown to reduce the risk of colon and breast cancer. It boosts the immune system and encourages T-cell formation, which defends our body against sickness and disease.
Bioflavonoids, which are found in citrus fruits, are considered a companion to vitamin C because they extend the value of it in the body. These nutrients have the capabilities to lower cholesterol levels and support joint collagen in arthritis cases.
The number one excuse for not eating the required five servings of fruits and vegetables each day is they are too expensive. However, as compared to the amount of money spent on prepackaged, processed, and fast foods, most fruits and vegetables (with the exception of those that are not in season) are not all that expensive.
Because frozen fruits and vegetables retain the majority of their nutritional value, they can be an excellent alternative when certain foods are out of season.
Someone who is not able to eat five servings of fruits and vegetables each day can also drink fruit and vegetable drinks in their place. Although this shouldn't become a habit, fruit and vegetable drink mixes can be an excellent substitute when you're rushed or traveling.
The need for fruits and vegetables in our diet is growing rapidly with the type 2 diabetes, heart disease, and high cholesterol, hypertension that result from the "Typical American Diet" of fatty meats, processed sugars, and refined grains.
