Grapes are a remarkably healthy food, whether one eats green, red, or purple versions of this popular fruit. They are one such food, and aside from helping you toward your diet goals, grapes provide a significant amount of nutrition to your body. Do not hesitate to make them as a part of your die, but if you have amedical condition, consult with your doctor about taking their seed extract or any other supplements.
One cup of grapes — a standard serving for fresh fruit — has 2 percent of the recommended daily intake for vitamin A and 1 percent for vitamin E. The percentages are based on a 2,000-calorie daily diet. Both nutrients are antioxidants, which help protect your cells from disease-causing molecules called free radicals. They also contain vitamin C, another antioxidant, but in trace amounts. The fruits contain five of the B-complex vitamins. As a group, B vitamins help your metabolism change the foods you eat into energy. This fruit serving provides 17 percent of the RDI for vitamin K, a nutrient that causes your blood to coagulate and prevents hemorrhages.
Fat and Calories
Grapes are made of almost 80 percent water. Because of this, they fill you up and keep you satisfied. They are also low in calories and have no fat, so you can eat an abundance of them without gaining weight. One cup of Catawba or Concord varieties only has about 60 calories. For a diet, choose fresh ones over dried ones in the form of raisins. The water is taken out of raisins, so if you eat the same amount you will take in many more calories. A 1-cup serving has 464 calories.
Grapes and their seed extract contain a variety of antioxidants. Antioxidants protect cells from the damage of unstable molecules and protect against inflammation. Cellular damage and inflammation lay the foundation for all kinds of diseases and accelerate the aging process. Regularly including this fruit in your diet or using a supplement like the seed extract could potentially benefit your overall health. One chemical diethyl malonate(105-53-3) occurs naturally in the fruits as a colourless liquid with an apple-like odour, and is used in perfumes.
Grapes also appear to have compounds which have antimicrobial properties, potentially reducing the risk of viral and bacterial infection in frequent consumers. Compounds known as flavanoids appear to reduce the risk of cancer, while a substance called resveratrol benefits the brain and nervous system. Resveratrol may also slow the aging process, although they will certainly not render anyone immortal.
Blood Vessel Health
The OPCs in grape seed extract appear to improve the condition and functioning of blood vessels. The University of Maryland Medical Center says high-quality research has shown it helps treat chronic venous insufficiency, a condition where blood vessels do not move blood through the body as efficiently. NCCAM says it might also help blood vessel disorders such as diabetic retinopathy and vascular fragility.
