Folk wisdom has always singled out fruits and vegetables as being indispensable for health, but it has only been within the last thirty years that we know why. Science and technology have isolated compounds in plants and vegetables that have literally been our life-savers. These are phytonutrients which all fruits and vegetables produce because their means of survival in the environment is through the release of disease-fighting phytochemicals.
Phytochemicals stimulate the production of protective self-repairing cells in plants. They also produce the same kinds of responses in humans. For example, they release protective enzymes that inhibit cancer-producing substances, thus reducing our susceptibility to disease. It makes sense for us to harness the powers of plants in our diets. Four sources of phytonutrients that cannot be ignored if we want to remain healthy and cancer free are berries, cruciferous and dark, leafy vegetables, soy and red wine.
Soy products contain genestein, which has been shown to have strong anti-cancer properties. It contains as well phytoestrogen, which has been shown to reduce the risk and spread of prostate cancer. Researchers suggest that the phytonutrient isoflavones, like phytoestrogen, may reduce the risk of breast cancer. Another isoflavone compound in soy called daidzein has also been found to improve cholesterol and triglyceride levels in women.
A study conducted at the Cedars-Sinai Medical Center in Los Angeles has uncovered evidence that this estrogen-like compound is the main reason for soy's healthy effects. Women with low estrogen levels seemed to have benefited most from daidzein, which reduced LDL cholesterol and total cholesterol levels, leading researchers to recommend that women include soy food products as part of their cardiovascular risk reduction strategies.
The phytonutrient, resveratrol, found in red wine, that literally makes wine drinking a cancer-fighting measure. Resveratrol is present in the leaves, twigs and bark of the grape vines. And red wine, which is fermented from grape skins, seeds and twigs tends to have large quantities of these cancer-fighting substances. Resveratrol has also been demonstrated to be a potent antioxidant (more potent than vitamin C alone) which can act synergistically with vitamin C, thus enhancing the effects of each. It also prevents the formation of blood clots and promotes the formation of new dendrites in the brain.
Fruits and fresh vegetables that we buy in the supermarket are not as nutritious as they should be due to the marketing practices of today. Green harvesting is the norm so that the fresh vegetables will make it through the long trip from field to market. When you grow your own fresh vegetables, you can allow them to ripen fully so that they are enriched with the vitamins, minerals, and antioxidants that our bodies need.
Phytonutrient supplements have inherent advantages over certain fruits and vegetables, such as carrots, which can excessively elevate one's blood sugar levels. Because phytonutrient supplements are only the extract of the pigments -- where the nutrients are especially concentrated -- they are a superior way to derive the best "essence" of fruits and vegetables, without consuming the excess sugars and calories.
