How do phytochemcials help prevent heart disease?

Phytochemicals perform many bodily functions that are protections against heart disease. For instance:

• They act as antioxidants, which prevent or repair cell damage, including damage to the innermost layer of the arteries.
• They make small blood vessels stronger and keep their walls healthy.
• They block enzymes that raise blood pressure.
• They prevent platelets from sticking to each other and piling up.
