Eggplant season is from August to October, although it is generally available all year long. Eggplant grows from a vine similar to a tomato and is a member of the nightshade family of plants. Eggplant is low in calorie, with only 35 calories per cup, and high in fiber, vitamins, minerals and antioxidants, according to the USDA National Nutrient Database.
Manganese is a trace mineral. It is needed to help form connective tissue, bones, blood clotting factors and sex hormones, according to the University of Maryland Medical Center. It is also a component of the antioxidant superoxide dismutase. As an antioxidant, superoxide dismutase prevents free radicals from damaging cells and may protect you against aging and some chronic diseases. Adult men need 2.3 milligrams of manganese a day and adult women need 1.8 milligrams. A 1-cup serving of eggplant provides 0.13 milligrams.
Thiamine is a water-soluble B vitamin. As a water-soluble vitamin, it is not stored in the body and without adequate intakes you can become depleted quickly, according to U.S. National Medical Library and National Institutes of Health MedlinePlus. Thiamine is needed for muscle function, flow of electrolytes, carbohydrate metabolism, enzyme function and the production of hydrochloric acid. Adult men need 1.2 milligrams of thiamine a day and adult women need 1.1 milligrams. A 1-cup serving of eggplant provides 0.08 milligrams, according to the USDA National Nutrient Database.
Folate is also a B vitamin. Folate is needed for the production and maintenance of new cells. Folate is especially important during periods of rapid growth, such as infancy and pregnancy, according to the National Institutes of Health Office of Dietary Supplements. Women of childbearing age need 400 micrograms of folate a day to prevent birth defects. Adult men also need 400 micrograms of folate a day. A 1-cup serving of eggplant provides 14.26 micrograms.
Vitamin B-6 is another water-soluble B vitamin. It is needed for the formation of enzymes, protein metabolism, red blood cell metabolism and proper functioning of the immune system, according to the Office of Dietary Supplements. Older Americans may be at risk for vitamin B-6 deficiency, says the Office of Dietary Supplements. Deficiency symptoms include confusion, depression, dermatitis and convulsions. Adult men need 1.7 milligrams of vitamin B-6 a day and adult women need 1.5 milligrams a day. A serving of eggplant provides 0.09 milligrams.
