High-protein diets, such as the Atkins Diet, work by decreasing the amount of carbohydrates and natural sugars a person consumes so she can lose weight quickly. Unfortunately, the American Heart Association points out that dieters lose out on vital nutrients when carbohydrates are restricted. Certain nutrients that are eliminated even help protect your vision.
Diet Effects
High-protein diets work by reducing the amount of carbs you eat. Carbohydrates are contained in bread, cereal, pasta and rice, as well as fruits and vegetables. According to the American Heart Association, reducing carbohydrates in the body makes you lose water weight. Eating solely protein also decreases your appetite.
Nutrients for Vision
Vitamins A, C and E are antioxidants that may help protect your eyes. AllAboutVision.com explains that consuming these vitamins from fruits and vegetables may help prevent vision problems as you age by fighting free radicals. Two other important nutrients for vision are lutein and zeaxanthin. According to the American Optometric Association, lutein and zeaxanthin act as a filter that prevents blue light from damaging the eye.
Dietary Effects on Vision
High-protein diets deemphasize foods such as fruits, vegetables and whole grains. These foods contain the nutrients that protect eye health. A diet that lacks essential nutrients can cause a variety of diseases, including macular degeneration and cataracts, says the American Optometric Association.
Prevention
The American Optometric Association recommends consuming 2 mg of zeaxanthin a day and 10 mg of lutein. Although these nutrients are best derived from foods, ask your doctor if a supplement is appropriate for you if your diet lacks certain foods. Colorful fruits and dark leafy vegetables contain all of the nutrients that can protect your vision. Opt for oranges, carrots, corn, spinach, collard greens, kale, romaine lettuce and broccoli.
Considerations
Eggs are a choice of foods in high-protein diets, and they also a source of lutein. Keep in mind that eggs are also high in cholesterol. The American Heart Association does not endorse high-protein diets due to the high amounts of fat and lack of nutrients. Such diets increase your risk of heart disease. High-protein diets can result in rapid weight loss, most of which is often gained back quickly. By making low-fat choices over an extended period of time, you will lose weight and be able to better maintain it, and you will not lose out on essential nutrients.
