Macular degeneration and foods: Ones to avoid and meal plans

Doctors recommend that people with macular degeneration avoid simple

Doctors recommend that people with macular degeneration avoid simple carbohydrates and foods high in cholesterol.

The macula is the part of the eyes that controls central vision. Macular degeneration is most common in people after 60 years of age.

According to a 2022 study, it currently affects 196 million people and is estimated to be 288 million by 2040.

Some common symptoms of macular degeneration include:

Health experts have established connections between the consumption of certain foods and the progression of macular degeneration.

This article explores foods to avoid for people with macular degeneration. We also discuss sample meal plans.

Refined carbohydrates are processed forms of natural carbohydrates. Industrial processing removes the nutritional components of carbohydrates, including beneficial fibers, vitamins, and minerals, resulting in a carbohydrate called empty calories.

Empty calories have a high glycemic index, are easily digestible, and can cause rapid spikes in blood glucose levels. The National Institute of Health (NIH) notes that a high glycemic index diet may lead to early-onset and progressive macular degeneration.

A 2020 article that examined the effects of various dietary patterns and carbohydrates on age-related macular degeneration found the following:

Foods with high cholesterol may affect the eyes and increase a person's risk of macular degeneration. This can occur when cholesterol blocks the blood supply to the eye, affecting central vision.

Examples of high cholesterol foods to avoid include:

People with macular degeneration should limit or avoid the same foods that are unhealthy for individuals without the condition. They should also avoid foods that cause considerable blood cholesterol fluctuations.

Older research shows that diets high in cholesterol cause the retina to degenerate, which is relevant to the development of macular degeneration.

A 2020 study associated a higher intake of trans fat — manufactured products that increase levels of cholesterol — with the presence of macular degeneration.

On the other hand, the researchers found potential protective effects against macular degeneration in people who consumed more polyunsaturated and monounsaturated fatty acids.

High cholesterol can affect the eyes in several other ways. This includes:

People need regular checkups with an ophthalmologist to monitor their eye function.

In addition to working with a doctor, it may help to meet with a dietitian who can help a person understand nutrition labels and map out a meal plan.

A 2015 study notes that higher adherence to a Mediterranean diet can lower the progression of macular degeneration.

Some simple ideas for the meal include:

People with macular degeneration need to reduce the number of refined carbohydrates and cholesterol consumed as this can increase the risks of macular degeneration.

Research suggests that a high fiber diet of fruits, vegetables, whole-grain toast, and oats can significantly benefit people with macular degeneration.
