Health Benefits of Vitamin E
Overview:
Vitamin E is a fat-soluble vitamin which is present in nature in eight different forms. It occurs in various food groups but its best dietary source is edible vegetable oils. This vitamin is of great importance to human health because it plays a crucial role in the management and prevention of various diseases and disorders. Let's have a look at how vitamin E improves health and well-being:
Improves vision:
A positive link is found between adequate dietary vitamin E intake and a reduced risk of developing age-related macular degeneration and cataracts. Vitamin E present in a variety of nuts and fortified cereals protects the eye cells from damage. Free radicals attack the eye cells and tissues and

Vitamin E plays an important role in increasing the bone density. It further reduces the loss of calcium from the bones by neutralizing the dangerous effect of free radicals. Oxidative stress causes damage to the bones and overall skeletal health. Vitamin E is a natural antioxidant that fights oxidative stress, restores bone strength and protects against bone loss. Furthermore, vitamin E inhibits the formation of compounds that accelerate bone resorption and negatively affect bone structure. Getting enough vitamin E boosts bone formation and reduces bone …show more content…
Human brain is highly susceptible to oxidative stress. Therefore, it becomes important to feed your brain with antioxidants such as vitamin E. Studies have reported that high level of vitamin E in the blood is associated with better cognitive performance and delay in the onset and preogression of Alzheimer's disease. Vitamin E inhibits the activity of compounds that cause cognitive decline and inflammation of the brain cells. Supplementation with vitamin E further lowers worsening of Alzheimer's disease symptoms which include confusion, mental decline, disorientation, difficulty in concentrating and forgetfulness.
Vision impairment is inevitable when Vitamin A is lacking in your system. In most cases, the issue of vision impairment abounds in the lives of children and even adults who don’t take foods rich in Vitamin A. When such is the case, the individuals involved will encounter series of vision problems such as night blindness, dry eye and so on. In most cases, mild deficiency of Vitamin causes bitots’ spots or changes in the conjunctiva. When the deficiency is very severe, dry eye will showcase.
...tical in preventing osteoporosis and developing fractures. One of the most important ways to prevent this disease is already taking calcium and vitamin D for building and maintaining healthy bone. With these supplements and following a healthy diet plan can help you gain these and provide you with more helpful nutrients. In following your healthy meal plan, one should take into consideration the amount of alcohol they are drinking because it can damage your bones, a plan in action to quit smoking or stay away from smoking and to get into a routine of daily exercise for yourself. Exercise is one of best ways to improve your health including strengthening your bones, balance and coordination. It can prevent falls and may reduce your risk of fractures. The ability to get some sort of exercise during your daily activities can lessen your chances of getting osteoporosis.
Retinoids can be used as a therapy to prevent Alzheimer’s disease. Vitamin A has an effect on many of the metabolic markers of Alzheimer’s disease. These include inflammation, oxidative stress, and amyloid β in the extracellular. Targeting the receptors for these processes may slow down or reverse Alzheimer’s disease.
Classically, vitamin D deficiency is known for its effects on bone, causing reduced mineralization, rickets and osteomalacia.[1, 3] However, many new roles of vitamin D have recently come to light, with more consequences attributed to its’ deficiency.[1] Vitamin D deficiency is increasingly associated with infectious diseases like tuberculosis, and non communicable diseases such as cancer, cardiovascular diseases, and stroke.[1, 6, 8–11]
...t one has it. Many scientists hypothesize that there is an inflammatory response in the brain when there is an extensive B-42 amassing. To slow or stop this, scientists theorize that the use of anti-inflammatory drugs, such as aspirin, could delay the swelling in the brain. Also, as scientists have known that taking a multi-vitamin tablet each day is good for you, there has been recent research demonstrating that the use of antioxidants may protect neurons, not just the immune system and keeping the body healthy by providing vitamins and minerals. These special supplements protect the neurons from the effects of the accruing B-Amyloid that would likely cause the plaque that causes AD.
Alzheimer's disease is the most common form of dementia, and this terminal, progressive brain disorder has no known cause or cure. Its greatest known risk factor is increasing age which is why is it is infamous for developing in the elderly, typically in ages 65 or over, however for the 5%(1) that develop Alzheimer’s in their 40s or 50s it is known as early Alzheimer’s. Because Alzheimer’s worsens over time, those with it tend to struggle with completing daily tasks especially elderly people. Given that there is no cure for Alzheimer’s, the treatments available slow the worsening of dementia symptoms and improve quality of life for those with Alzheimer’s and their caregivers. It is not known what causes Alzheimer's, however, those with Alzheimer's have been found to have abnormal amounts of protein (amyloid plaques) and fibres.(The amyloid plaques and fibres are found in regions of the brain where problem solving and thinking take place e.g The cerebrum.) Due to the unusual amounts of amyloid plaques and fibres, it reduces the effectiveness of healthy neurons and eventually, destroying them.
SCURVY--caused by a lack of vitamin C--also affects bone tissues. A study in the late 1980s indicated that the mineral boron is nutritionally important, as well. Apparently, it reduces loss of the bone minerals

The 13 well-identified vitamins are classified according to their ability to be absorbed in fat or water. The fat-soluble vitamins-A, D, E, and K-are generally consumed along with fat-containing foods, and because they can be stored in the body's fat, they do not have to be consumed every day. The water-soluble vitamins-the eight B vitamins and vitamin C-cannot be stored and must be consumed frequently, preferably every day (with the exception of some B vitamins, as noted below).
Vitamin E in all its forms, functions predominantly as an antioxidant by protecting cells from free radicals in the body. Vitamin E works as an antioxidant by donating a hydrogen atom from a hydroxyl group to a free radical within the body. Vitamin E also plays a role in immune system function and protects cell membranes and regulation of gene expression. Vitamin E has been studied to uncover other medical usages, including prevention or treatment of many health conditions [1].
Vitamin D is a necessary component for calcium absorption to prevent boss loss. Nutritionally our body can create vitamin D by sun exposure however many factors can prevent our bodies to create vitamin D such as using sunblock or not getting enough sun exposer from daily routine. Vitamin D can be found in many foods that we such as milk including almond milk, eggs yolks, saltwater fish, and liver. Other vitamins that can help prevent bone loss are vitamin A and C. Vitamin C is an antioxidant which helps reduce oxidative stress which can have a negative effect on the cells in the body. This helps protect against inflammation which takes away calcium from the bones. Vitamin C can be found in many foods such as papaya, bell peppers, broccoli, Brussel sprouts, strawberries, pineapples, oranges and kiwifruit and fruit juices have supplement vitamins. Vitamin A is important for bone growth, vision, cell division and cell differentiation. There are two different forms of vitamin A are retinol and beta-carotene. Retinol can be found in meat, poultry, fish and dairy products while beta-carotene can be found in fruits, vegetables and

There is growing evidence that low levels of vitamin E do make you more likely to develop cancer. This is good news because we can do something about low levels of vitamin E – get more, and reduce our cancer risk. The antioxidant effects of vitamin E seem to be what is giving this protection. So far there is evidence of this effect in acting against colon, cervical and breast cancers and possibly lung cancer. Another benefit can come in patients who are receiving radiation therapy for cancer in whom vitamin E appears to help reduce the side effects of treatment.
The human body requires small amounts of nutrients in microgram or milligram quantities in our diet because it cannot synthesize the necessary amounts on its own. These nutrients are considered micronutrients. Micronutrients are a combination of water, vitamins, and minerals. Vitamins are organic compounds that do not provide energy, but are essential to the body in helping “aid in metabolism, as well as the growth, development and maintenance of body tissues” (Byrd-Bredbenner, Moe and Beshgetoor 402). Vitamins are broken down into two groups, water-soluble and fat-soluble. The water-soluble vitamins are the B-vitamins, and vitamin C. The fat-soluble vitamins are A, D, E, and K. Minerals are needed in even smaller amounts, however these inorganic substances are necessary for “cell metabolism, nerve impulse transmission and growth and development” (Byrd-Bredbenner, Moe and Beshgetoor 485). Minerals can be categorized into major or trace minerals. The major minerals include Sodium, Potassium, Chloride, Calcium, Phosphorus, Magnesium, and Sulfur. Trace minerals are Iron, Zinc, Copper, Manganese, Iodine, Selenium, Chromium, Fluoride, Molybdenum and Ultratrace minerals.
Vitamins, a group of organic substances required in our diets in small amounts for growth and nutrition, are usually found in foodstuffs or taken as supplements. Yet vitamins probably present a wider gap between myth and reality in the layman's understanding than almost any other area of our diet. Surveys have found that while a majority of Americans do take vitamin supplements on a regular or occasional basis for reason of health concerns, there exists enormous confusion about the actual purpose and benefits of this practice ("Use of Vitamin and Mineral Supplements in the United States," 1990:161). Most people have a recognition that Vitamin C prevents scurvy, that Vitamin A is found in fish-liver oils, or that Vitamin D is found in dairy products; many people believe that Vitamin E preserves youth and prevents sterility, or that Vitamin C can present colds and cancer. Beyond this, however, there is still considerable ignorance and widespread myth.
