* Vitamin C : Zucchini serves as a good source of vitamin C. A water-soluble antioxidant, vitamin C dissolves in your body fluids and protects your cells from free radicals, which are highly reactive compounds that oxidize your DNA, lipids and proteins, causing cellular damage. Getting enough vitamin C in your diet also aids in nerve cell communication, helps your body metabolize cholesterol and keeps your tissues strong. A cup of chopped zucchini contains 22 milligrams of vitamin C, which is 24 percent of the recommended daily intake for men and 29 percent for women, set by the Institute of Medicine.

* Lutein and Zeaxanthin : Zucchini also provides you with lutein and zeaxanthin, two phytonutrients that belong to the carotenoid family, which is the same nutrient family that includes beta-carotene, a source of vitamin A. Lutein and zeaxanthin promote healthy eyesight. They filter light rays as they enter your eye, helping to ensure that harmful rays can't damage your eye tissues. While, as of September 2013, the Institute of Medicine has not set a recommended daily intake for lutein and zeaxanthin, the American Optometric Association notes that intakes of at least 6 milligrams per day can reduce your risk for age-related macular degeneration, an eye disease that causes blindness. A cup of chopped zucchini provides 2.6 milligrams of lutein and zeaxanthin, or 43 percent of this intake goal.

* Heart Attack and Stroke Prevention : A one cup serving of zucchini contains over 10% of the RDA of magnesium, a mineral proven to reduce the risk of heart attack and stroke. Zucchini also provides folate, a vitamin needed to break down the dangerous amino acid homocysteine, which - if levels in the body shoot up - can contribute to heart attack and stroke.

*Lower Blood Pressure : Along with magnesium, the potassium found in zucchini helps lower blood pressure. If unchecked, hypertension, or high blood pressure, can lead to arteriosclerosis (blood vessel damage), heart attack, stoke, and many other serious medical conditions. Both the potassium and magnesium in zucchini, however, can help alleviate the stress on the body's circulatory system.
