Is there a relationship between macular degeneration and fat intake?

A large scale, a detailed medical study, showed a positive correlation between human fat and their macular degeneration level. Macular degeneration occurs when part of the eye is called macula, it deteriorates. This causes many problems such as the loss of the ability to distinguish fine details, night blind and blurred or distorted vision. Because symptoms occur with age, it is very important to determine the causes of macular degeneration so that people can perform preventive care. It has been shown that a fat -rich diet, especially certain types of fat, has a high probability of increasing the risk of this type of eye state.

In twelve years, medical scientists watched at Tufts University nearly 90,000 people aged 50 or older. They watched their detailed fat intake and measured their macular degeneration and published their results in 2001. They generally found that people who were given 42% or More of their fat calories have more often developed macular degeneration. Overall recommended people starFor 50 years, they kept their calories from fat up to 20-25%. However, the study also showed differences in different types of fat intake, such as saturated versus polyunsaturated and trans -tuk to cause a variety of macular degeneration.

This study found that some fats especially "bad". Diet -rich diets such as roast commercial goods, and dairy products were approximately 225% more likely to cause macular degeneration. Surprisingly small parts of these foods proved dangerous. Only one day of things such as ice cream, bacon, fries, whole milk, hot dogs, biscuits, sausage, butter or cake were unhealthy. Uncooked meat, such as steak, lamb or pork, should only be eaten once a week before the risk of macular degeneration of subjects increased by 35%. These meals are examples of polyunsaturated fats that include omega-6 fatty acids.

However, there is no connection between macular degeneration and "good" fat intake, which includes omega-3 fatty acid or "bad" saturated fat. Alternatives of safe fat include fish such as canned tuna or fresh salmon and nuts. They can be consumed almost every day without observable damage to macular health. Scientists do not understand why saturated fat, which is otherwise dangerous for cardiovascular health in other circumstances, has not been associated with macular degeneration. Although this study is strict, nutritionists are still learning what makes some fats beneficial and others harmful.
