Phytochemicals

Question: Do u agree that foods, not supplements, are the best and safest source of phytochemicals or nutrients? Can u defend the statement in the "Controversy" that foods, not supplements, are the best and safest source of phytochemicals.

Answer: Foods are the best and safest source of our nutrients including vitamins, minerals and phytochemicals. If a person is not getting a good variety of foods, then they may not be receiving all of what hey need and a supplement is an insurance. The more colorful the fruit and vegetable the better. The fresher the better. The least cooked the better. The more variety the better. The more servings the better. Avoid processed foods.(Those that are boxed or canned and already made for you) Avoid many restaurant foods. Know where your foods came from and what chemicals might have been used on them.

Question: Do you agree that foods, not supplements, are the best and safest source of phytochemicals? How can you defend the statement in the "Controversy" that foods, not supplements, are the best and safest source of phytochemicals.

Answer: Foods are safer: It is rare to have a toxic overdose from a food. Foods are natural, and unlike a supplement, food is unlikely to have dangerous or unknown impurities or additives, which could occur with man-made supplements. Foods are better: Studies that show the benefit of a phytochemical are usually based on food consumption, not supplements. Taking the phytochemical apart from the food does not guarantee that you get the same result. Some things work in combination.

Question: What are phytochemicals and what is their function? hey what do phytochemicals do? and what are they? Please Help

Answer: The term "phytochemicals" refers to a wide variety of compounds produced by plants. They are found in fruits, vegetables, beans, grains, and other plants. Scientists have identified thousands of phytochemicals, although only a small fraction have been studied closely. Some of the more commonly known phytochemicals include beta carotene, ascorbic acid (vitamin C), folic acid, and vitamin E. http://cancer.org/docroot/ETO/content/ETO_5_3X_Phytochemicals.asp?...

Question: What are the differences between phytochemicals, flavonals, and antioxidants? I need a clear explanation

Answer: Phytochemicals are plant or fruit derived chemical compounds. The term flavonoid refers to a class of plant secondary metabolites. An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules. ..

Question: What are the best kind of foods that have high levels of calcium, iron, and phytochemicals?

Answer: leafy greens like spinach, kale, collard greens.... just don't over cook 'em cuz you lose all the good stuff.

Question: How do antioxidants and phytochemicals defend against free radical damage.?

Answer: Free radicals steal electrons from your body. Antioxidants give up electrons. So if you take antioxidant food into your diet, the free radicals will attack the antioxidant electrons saving the electrons in your body. I have been doing some research and you can find some great information on a fruit that tops the lists of food that contain antioxidant power. Blueberries,yum!!!

Question: Why is color important when choosing foods with phytochemicals? ok i need help with this question

Answer: Beecause some of the phytochemicals are the same chemicals which give the plants their specific colors. Carotene is what produces orange color of carrots, xanthophyll provides yellows, while anthocyanins can appear red, purple, or blue according to the pH of the plant they are in. So by eating a variety of "colors", you're getting more phytochemicals than if you limited your diet to one color.

Question: What it means by plant secondary metabolites? Why the phytochemicals are known as plant secondary metabolites?

Answer: Secondary metabolites are those chemicals produced in metabolic processes which are not NEEDED for the plant to live. Example: Nicotine Brassica plants do not NEED to produce nicotine to live, but it is a very nice insect repellent. And it attects human physiology (that's evolution for you). Many secondary metabolites are only expressed in respose to some environmental stress. Drought, soil types, other vegetation, pests, disease, herbivores... These chemicals tend to produce some type of reaction- initiation of cascade reactions in nearby plants (plant-to-plant communication), production of chemicals to taste bad to the herbivores, etc.

Question: are phytochemicals inert properties of plants? are phytochemicals inert properties of plants? or plants make them due to the environment? can the same plant species have different phytochemicals?

Answer: The word phytochemical is currently being used to identify the chemical constituents of plants that are not in the usual class of proteins, fats, carbohydrates, vitamins and minerals used as part of our nutritional requirements. Phytochemicals are all the other constituents that may or may not have health-related effects, both positive and negative." Many potential health benefits and functions of phytochemicals have not yet been recognized; in fact, some of the compounds themselves have not been identified. There's a frenzy of epidemiological, animal and human studies, however, and promising results indicate that specific phytochemicals may prevent chronic diseases (including cancer), help manage symptoms of chronic disorders, improve immune response, and even minimize negative effects of aging. Although some of the preliminary results are exciting, information on certain substances is extremely limited, inconclusive or contradictory. In their haste to rush new functional food products to market, some companies overlook the lack of evidence for efficacy of these compounds. Before adding phytochemicals to a food, manufacturers should study the available research, be aware of any federal regulations and recommended doses, and assess whether benefits outweigh any risks. At the very least, added ingredients should do no harm. Researchers are just beginning to quantify phytochemical content of specific ingredients - something of a challenge, since these compounds can vary within a given food.

Question: What plants are rich in ' phytochemicals '?

Answer: Phytochemicals are non-nutritive plant chemicals that have protective or disease preventive properties. There are more than thousand known phytochemicals. It is well-known that plant produce these chemicals to protect itself but recent research demonstrate that they can protect humans against diseases. Some of the well-known phytochemicals are lycopene in tomatoes, isoflavones in soy and flavanoids in fruits. They are not essential nutrients and are not required by the human body for sustaining life. How do phytochemicals work? There are many phytochemicals and each works differently. These are some possible actions: Antioxidant - Most phytochemicals have antioxidant activity and protect our cells against oxidative damage and reduce the risk of developing certain types of cancer. Phytochemicals with antioxidant activity: allyl sulfides (onions, leeks, garlic), carotenoids (fruits, carrots), flavonoids (fruits, vegetables), polyphenols (tea, grapes). Hormonal action - Isoflavones, found in soy, imitate human estrogens and help to reduce menopausal symptoms and osteoporosis. Stimulation of enzymes - Indoles, which are found in cabbages, stimulate enzymes that make the estrogen less effective and could reduce the risk for breast cancer. Other phytochemicals, which interfere with enzymes, are protease inhibitors (soy and beans), terpenes (citrus fruits and cherries). Interference with DNA replication - Saponins found in beans interfere with the replication of cell DNA, thereby preventing the multiplication of cancer cells. Capsaicin, found in hot peppers, protects DNA from carcinogens. Anti-bacterial effect - The phytochemical allicin from garlic has anti-bacterial properties.

Question: E coli and plant phytochemicals? I know alot of the phytochemicals in plants (resveratrol in grapes and falcarinol in carrots for instance) protect them for bacteria, fungi, etc. Is the e coli bacteria harmful to the spinach plant itself and if so doesn't the plant produce chemicals to destroy it? From what I understand the recent outbreak was from contaminated soil and/or water so the bacteria is in the actual plant not on the surface of the leaves.

Answer: E. coli isn't harmful to plants; in fact, there's some evidence it increases photosynthetic output. Regardless, the E. coli survives on the external surface of the leaves, mostly, not inside.
