Evidence-based benefits of phytochemicals -
Phytochemicals are compounds in plants. These substances are found in plant-based foods such as fruits, vegetables, whole grains, nuts, seeds and legumes.
They give plants their color, flavor and aroma. Much of the current evidence on the benefits of phytochemicals has come from observing people who eat mainly plant-based diets. These people have been shown to have significantly lower rates of certain types of cancers and heart disease.
Eating a diet that is mostly plant-based is recommended by the American Institute for Cancer Research. Although currently there is no conclusive evidence that any one specific phytochemical is guaranteed to reduce cancer risk or help eliminate cancer if you have it, promising evidence indicates that phytochemicals may have the potential to:.
Each plant food has many different phytochemicals; there are more than phytochemicals in a carrot alone! All of these phytochemicals have different functions in the body, and many of them complement one another. Evidence shows that taking phytochemicals in supplement form may not provide the same benefits as eating the whole plant foods, because phytochemicals in supplements may not be as easily absorbed by the body as those from food sources.
The fruits and vegetables with deeper and brighter colors or with stronger flavors are often the best sources of phytochemicals. Phytochemicals are foods that contain chlorophyll.

Power of Phytochemicals - Jed Fahey - The Proof Podcast EP 201
Evidence-based benefits of phytochemicals -
What most researchers do agree on is the benefits. But the American Cancer Society recommends eating a diet high in vegetables and fruits. You may have heard of beta-carotene, lycopene, lutein and zeaxanthin. Carotenoids inhibit cancer growth, improve immunity, support vision and promote skin health.
They can be found in broccoli, carrots, cooked tomatoes, leafy greens, sweet potatoes, winter squash, apricots, cantaloupe, oranges and watermelons.
Anthocyanins, quercetin and catechins are all types of flavonoids. They inhibit tumor growth, reduce inflammation and boost immunity. Apples, onions, soybeans, coffee, tea and citrus fruits like oranges and lemons are all sources of flavonoids.
Indoles and glucosinolates, like other phytochemicals, can help lower your cancer risk. They are known to prevent tumor growth and decrease production of cancer-related hormones.
They can be found in broccoli, cabbage, kale, cauliflower and Brussels sprouts. Phytic acid is a type of inositol. Inositols prevent cell damage and can be found in bran from corn, oats, rice, rye and wheat, as well as nuts and soybeans. Like indoles and glucosinolates, isoflavones inhibit tumor growth and limit the production of cancer-related hormones.
Ellagic acid and resveratrol are two types of polyphenols. They can prevent cancer formation and inflammation. When it comes to phytochemicals, the key is to get them from whole foods -- not supplements.

Additionally, the Flaviola Health Study reported that cocoa flavanol intake can improve endothelial function in those with cardiovascular risk factors and disease.
Through this study, intake of cocoa flavanol significantly predicted a lowering of year risk for CHD, heart attack, CVD, and death from CVD or CHD in high risk subjects, as well as the potential to maintain health in low-risk subjects 5.
Critical reviews of studies available in the literature support the concept that diets high in fruits and vegetables reduce the risk of hypertension, CHD, stroke, and other diseases evidenced by dose-response relationships 7.
Several research groups have confirmed the critical role that can be played by phytochemicals in reducing the risk for several diseases such as cancer and inflammatory conditions 8.
For example, recent research has cited various effects of phytochemical consumption on cancer prevention 9 , reduction in stroke risk 10 , and Type 2 Diabetes prevention Proposed mechanisms of action for these findings include inhibition of lipid oxidation, lipid-lowering effects, hypoglycemic- and insulin-lowering effects, antioxidant activity, anti-inflammatory activity, and anti-proliferative or apoptotic cell death activity Plant-based foods like fruits, vegetables, and grains, contain several bioactive phytochemicals which may decrease the risk of chronic diseases.
The health effects attributed to the consumption of phytochemicals are primarily due to the synergistic actions of bioactive dietary components which include micronutrients and phytochemicals. It is largely accepted that the additive effects of the combinations of various phytochemicals in whole plant-based foods are shown to have stronger protective actions than single, isolated phytochemical compounds Quantitative recommendations for the antioxidants Vitamin C, Vitamin E, and selenium are supported by the Panel on Dietary Antioxidants and Related Compounds, Subcommittees on Upper Reference Levels of Nutrients and Interpretation of Uses of DRIs, and the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes within the Institute of Medicine.
Beta-carotene and other carotenoids are discussed, but quantitative recommendations for their intake are not given at this time. Requirements for beta-carotene or other carotenoid intake cannot be established due to lack of understanding of the exact mechanisms of these nutrients and their importance to health.
However, recommendations for increased consumption of carotenoid-rich fruits and vegetables are supported Because it is hypothesized that the beneficial health effects observed from phytochemicals are related to the synergistic mixture of phytochemicals and other nutrients found in whole foods and its components, consumption of variety of plant-based foods is encouraged.
In clinical studies, when phytochemicals are isolated from the food source and taken alone as a supplement, individual compounds studied do not have consistent preventive health effects.
Furthermore, the efficacy and long-term safety of many bio-active compounds as dietary supplements, especially at pharmacologic doses, requires further study Download PDF. Institute of Nutrition Science, University of Giessen, Giessen, Germany. This Site.

Phytochemiclas also have antioxidant and anti-inflammatory properties that can help support a healthy human body. There are thousands of phytonutrients found in plants and related foods.
