Five worst foods for eye health
Limiting these foods can help control the amount of toxin buildup in your body
How your diet impacts eye health: Foods to avoid for better vision
Having a healthy diet is essential to maintaining your eye health as you age. While it’s always important to add nutrition to your diet through fruits, vegetables and whole grains, it’s also essential to cut out certain foods which may be compromising your eye health over time.
Here are five foods you should try to limit to preserve your visual acuity and keep your eyes healthy.
1. White bread and pasta
Simple carbohydrates like those found in white bread and pasta are easily digested and absorbed, which can spike blood sugar1. These rapid spikes put strain on the pancreas, which tries to keep the body’s blood sugar level steady2. If the pancreas is chronically stressed, then this can impair its ability to keep blood sugar at steady levels, resulting in chronically elevated blood glucose2. In turn, this can result in chronic inflammation and accumulation of toxins, which can harm cells2.
For eye health, the accumulation of toxins can damage cells in the eye responsible for maintaining eye health and visual acuity. As such, degeneration of eye cells can lead to a variety of age-related diseases like age-related macular degeneration (AMD), cataracts and diabetic retinopathy2.
Therefore, it’s important to limit the amount of simple sugars in your diet from foods like white bread and pasta to help your body maintain blood sugar levels and reduce the amount of toxins that your eye cells are exposed to. Whole grain pastas and bread are great substitutes since they’re digested more slowly and don’t cause the same spikes in blood sugar2.
2. Prepackaged foods
Prepackaged foods are loaded with sodium; eating too much processed food can have negative effects that reverberate throughout your body. It’s estimated that in America, as much as 75 per cent of dietary sodium comes from prepackaged and processed foods like soup, tomato sauce and condiments3.
Too much sodium in your diet is associated with high blood pressure, also known as hypertension3. Importantly, hypertension is linked to eye problems like diabetic retinopathy and blood vessel damage that can lead to vision loss1.
Eating less prepackaged food can reduce your chance of developing eye diseases like AMD or diabetic retinopathy1; however, if you do eat prepackaged foods, try to look for those with labels marked “low sodium” to help keep your sodium intake in check3,4.
3. Fried foods
High heat cooking methods used to make fried foods like doughnuts, french fries and eggrolls can increase the production of toxins that can damage the cells in your body and contribute to the development of various health conditions5. Further, frying can increase the amount of trans fats in cooking oils, which can cause inflammation5.
This inflammation can further increase the accumulation of toxins in your body that can damage and kill cells, including the cells in your eyes1,5. As a result, eating lots of fried foods tends to be associated with conditions like AMD and diabetic retinopathy1.
4. Sugary drinks
Drinks like sodas, juice and energy drinks are loaded with sugar1. Consuming all this sugar puts you at risk for health conditions like Type 2 diabetes and heart problems1.
Importantly, these health conditions are associated with eye diseases like AMD and diabetic retinopathy, so it’s important to limit your sugar intake by reducing your consumption of sugary drinks1. Water is the best alternative1.
5. Processed meats
Certain foods including processed meats are notorious for containing high quantities of sodium which can lead to hypertension, and in turn, eye conditions like AMD and diabetic retinopathy4. Some examples of processed meats include bacon, deli meats and hot dogs.
For some brands, just six slices of deli meat can have as much as half of the sodium you should consume in a day4. As such, it’s important to eat minimally processed meats to reduce your sodium intake and decrease your risk of hypertension and associated eye health conditions3,4.
How to protect eye health with your diet
Some foods produce toxins that harm the cells in your eyes and contribute to the development of various eye diseases. Limiting or cutting out these foods—while also eating a variety of fruits and vegetables containing vitamins essential for eye health—can help prevent eye diseases.
