Prevent Cancer & Heart Disease with Phytochemicals

Perhaps you have heard of the term phytochemical. However, you may not know what it means or why you need it. Simply put, phytochemicals are naturally present substances found in fruits and vegetables. While these non-nutritive plant chemicals are not essential for our bodies, consumption is very important as they can help ward off certain types of cancers and lower the risk of heart disease.

Food: The Best Source of Phytochemicals

There are more than 1000 phytochemicals found in food sources. These chemicals act as antioxidants, phytoestrogens, enzyme aids, and serve as antibacterial functions. According to both the researchers, it is important to eat whole foods to get the maximum benefit of phytochemicals. Scientists know that phytochemicals work with the vitamins, minerals and fibre in foods to synergistically protect against aging, heart disease, and cancer. Taking a supplement is not recommended to get these powerful chemicals into your body.

Eat 5 to 9 Servings of Fruits and Vegetables Everyday

A recommended daily amount of phytochemicals has not been established. However, the NCI recommends striving for at least 5 to 9 servings of fruits or vegetables a day to get adequate amounts of these important chemicals as well as other vitamins, minerals, and fiber.

Serving sizes for fruits and vegetables include:

• 1 cup of 100% natural fruit or vegetable juice
• 1 cup of cut up fruit or vegetables
• 2 cups of leafy greens
• 1/2 cup of dried fruit.
