When you explore grapefruit nutrition you will find that a grapefruit and its juice are loaded with vitamins, minerals, and anti-oxidants. White, pink and red grapefruit all have lots of vitamins C and A as well as good amounts of folic acid, fiber, calcium and potassium. Lycopene, which is found only in pink and red varieties of grapefruit is a phytochemical or antioxidant which can prevent certain types of tumors.
The Benefits of Grapefruit Nutrition
Another facet of grapefruit nutrition is that they contain no fat, sodium or cholesterol. That makes them excellent for people who are trying to lower calorie consumption or lose weight. Grapefruit juice can help people lose weight but it is usually short-term because most of the pounds lost are fluids. One-half of a grapefruit has only sixty calories and an eight-ounce glass of juice has less than one hundred calories. Because of their high water content, grapefruit can make you feel full, which can help you eliminate snacks and overeating.
One of the most important aspects of grapefruit nutrition is the amount of antioxidants they contain. Free radicals are chemicals produced in our cells by the body’s natural process of using oxygen. They can also be impacted by air pollution or smoking. Even exercising regularly can produce harmful free radicals. Scientists have linked free radicals to cellular damage that increases the likelihood of contracting a form of cancer or heart disease. Grapefruit have a high content of the antioxidant lycopene, which can prevent certain forms of cancer from developing.
The antioxidant, beta carotene, is also present in grapefruit. In the body, beta carotene is changed into vitamin A, which has positive effects in several areas, including cell division and differentiation, the reproductive process, vision–affecting macular degeneration, and also helping bone growth which is preventative of osteoporosis. Another anti-aging effect of consuming grapefruit is that it produces collagen, which can repair and prevent skin damage.
The immune system benefits both from the grapefruit’s concentration of vitamin C and from its phytochemicals. Vitamin C can also help the human body to absorb iron, which is particularly important for women. Vegetarians also sometimes suffer a lack of iron and can benefit from eating grapefruit as well. In addition, grapefruit nutrition consists of limonoids, monoterpenes and terpenes–which produce enzymes that can help prevent cancers, along with bioflavonoids, which stop other enzymes that make tumors grow. People suffering from a variety of inflammatory diseases, including lupus, can see benefits from eating grapefruit. Usually one a day is recommended.
When picking out which grapefruit to buy, avoid ones with a soft spot on the end that has the stem. This will cause it to spoil. Grapefruit skin need not be perfect and patches of green are meaningless. You should pick out the heaviest fruits because these will have the most juice. You can store a grapefruit at room temperature for up to a week, and they will last for up to three weeks in the refrigerator.
