The ocean holds about 97 percent of the Earth's water; the remaining three percent is distributed in many different places, including glaciers and ice, below the ground, in rivers and lakes, and in the atmosphere. According to the U.S. Geological Survey, there are over. of water on the planet.
Phytochemicals are compounds that are produced by plants (phyto means plant). They are found in fruits, vegetables, grains, beans, and other plants. Some of these phytochemicals are believed to protect cells from damage that could lead to cancer.
Because these phytochemicals are in the fruits, vegetables, beans, and grains you eat, it's fairly easy to include them in your diet. A carrot, for example, has more than 100 phytochemicals. Nutrition researchers estimate that more than 4,000 phytochemicals have been identified, but only about 150 have been studied in depth. More research is needed to find out which phytochemicals may offer benefits in reducing the risk of cancer.
