Vision benefits from lutein

With the wide selection of lutein products, some people become skeptical about the effectiveness of these products in various forms. Some sellers make promising claims about their lutein products, but people with poor vision may wonder whether lutein will actually improve vision.

In fact, lutein products can only help patients with bad vision, which is exactly caused by a lutein deficiency. Lutein in the eyes can protect eye tissue from the damage caused by free radicals, which are highly reactive atoms. These free radicals in the eye act on other healthy atoms and damage them, because they require a supply of free electrons. Lutein can effectively fight against these radicals.

In either dry or wet form, age-related macular degeneration is the most common result of these reactive radicals, especially in elderly individuals. And lutein has been found to reverse macular degeneration by combating these radicals and thus improve overall eyesight.

Accounting for 80% of vision defects, dry form of AMD is usually caused by abnormal growth of blood vessels below the retina, which in turn results from reactive chemicals in the tissue. Fortunately, lutein supplements have proven to reverse this condition a lot.

In fact, lutein acts like a neutralizing agent and prevents harmful light rays from damaging the tissue in the macula, which is situated in the center of the retina. As a result, a deficiency of lutein can lead to eye tissue damage.

Lutein is actually only one of the 600 carotenoids in the nature and it is the only one present in the macula of the eye. This lucky carotenoid is available from all the green leafy vegetables consumed by ordinary people every day. A healthy way is to take lutein by eating a nutritious meal every day, including lots of fruits and vegetables.

However, some people have no time to maintain such a balanced diet but they also want to get enough lutein every day. Nutritional supplements are a good choice for those people. It is important to strictly follow the doctor’s instructions on the dosage of these supplements and the way they are administered.

A healthy diet for cataracts prevention

Cataracts have become one of the most significant causes of blindness, so that a large number of studies and researches are focusing on the way to prevent cataracts or slow down their progression. Herbs have been proved to be effective in decreasing the risk of cataracts in mice, but relative researches in human body are rare. You should be cautious about taking herbs as a medicinal remedy. Many more studies are now underway about the influence of a healthy diet on cataracts prevention. Antioxidants and certain vitamins are considered possibly effective to decrease cataracts and slow their advancement.

Exposure to pollution, chemicals, smoking, radiation exposure and unhealthy foods can cause free radicals, which in turn lead to oxidation in human body including eyes. Free radicals in the body have unpaired electrons so that they stole an electron from another molecule. This unpaired molecule in turn tries to get an electron from another molecule. In this way, many healthy cells of organs and other tissues will be damaged. This process is named oxidation, which damages proteins and fats in the eye’s lens and causes cataracts.

Be clear of the principle of oxidation, nutrient experts recommend antioxidants including some vitamins and phytochemicals to reduce oxidation formation so that cataracts can be avoided. Studies have showed that antioxidants such as vitamin C, A and E and lutein have potential effect in preventing cataracts. Antioxidants can be found in foods such as fruits and colorful or dark green vegetables. These vegetables also contain folic acid and calcium, which may also reduce the risk of cataracts.

In this consideration, experts recommend a healthy diet that includes fruits, vegetables and whole grains. Fish are rich in omega-3 essential fatty acids, which may be also effective. An exactly healthy diet should contain nine servings of fruits and vegetables, three serving of 100% whole grains every day and two servings of fish every week. And the daily calories consumption should not exceed the basic need to maintain a healthy weight.

People still have different opinions about the sources of those nutrients, antioxidants and phytochemicals. In the market, dietary supplements are available in many forms. While some experts insist on a healthy diet, others argue that dietary supplements are helpful addition to even a healthy diet.

A healthy diet should avoid unhealthy foods such as fried foods, processed foods, sugary foods, and foods rich in sodium. High consumption of salt and sugary may increase the risk of cataracts. Extra soft drinks, desserts, greasy snack foods and fast foods should also be reduced or stopped. Just enjoy delicious fruits, vegetables and fresh fish.
