What foods are good for your eyesight?
If you want to protect or even improve your eye health, you should consume vegetables and fruits. A whole food plant-based diet is rich in antioxidants. Your eyes need carotenoids and other antioxidants, such as vitamin C, to function properly. For instance, carotenoids can filter the harmful blue light, protecting eyes.
Beta-carotene, lutein and zeaxanthin are the most important carotenoids. Vegetables and fruits are carotenoid-rich foods. As a rule of thumb, colorful plants are the best sources of carotenoids.
Try to consume many colorful vegetables. Carotenoids are responsible for the color of vegetables. A colorful salad is a great way to boost your carotenoid intake. Spinach, broccoli, or even beet leaves are great options.
Additionally, you can add fruits or seeds. They are rich in nutrients and healthy fats. Moreover, flaxseeds, chia seeds, hemp seeds, and walnuts are good sources of omega-3s. Omega-3 fatty acids are so important for good eyesight. You should consume foods rich in omega-3s daily.
Last, but not least, consider consuming a teaspoon of moringa powder daily. Moringa powder is the best food supplement for good vision. Moringa is particularly rich in beta-carotene, lutein and zeaxanthin. Furthermore, it’s high in antioxidants.
The worst foods for eye health
But, if you really want to protect your eyes you should avoid certain foods, as well.
The worst foods for eye health are fried, sugary, salty, oily foods, or foods high in glycemic index.
Why fried foods are bad for eye health?
You should avoid fried foods.
Great amounts of vegetable oils aren’t good for your health. Vegetable oils are calorie-dense. This means that vegetable oils are low in nutrients, but high in calories.
Furthermore, a percentage of vegetable oils is transformed into trans-fat. A really dangerous for health type of dietary fat.
Moreover, we should avoid the consumption of great amounts of vegetable oils for many other reasons…
Omega-6s to omega-3s ratio
The human body needs omega-3 fatty acids and omega-6 fatty acids to function properly. Preferably, we should consume equal amounts of both types. A diet that contains up to 4 times more omega-6s than omega-3s in considered healthy.
In other worlds, the closer the omega-6s to omega-3s ratio is to 4:1, the better.
Unfortunately, most common vegetable oils are rich in omega-6 fatty acids. So, a standard Western diet is pretty high in omega-6s. This type of diet can provide 20 times more omega-6s than omega-3s.
When the omega-6s to omega-3s ratio is 20:1 many health problems can occur. That’s because excess consumption of omega-6s can cause chronic inflammation. Fatty liver disease, cardiovascular disease, obesity, rheumatoid arthritis, and Alzheimer’s disease are some common diseases that chronic inflammation can cause (1).
Studies have confirmed that high consumption of omega-6s increases the change of age-related macular degeneration (2). Protect your eye health… Increase omega-3s, decrease omega-6s…
Hence, better avoid high consumption of vegetable oils, such as sunflower, as they are high in omega-6s. On the contrary, canola oil and flaxseed oil are high in omega-3s. They should be your first option. In any case, use them in moderation. They are pretty high in calories.
Protect your eye health avoiding foods high in trans-fats
Trans-fats are pretty dangerous. They can cause cardiovascular disease and Alzheimer’s disease (3).

- trans fats are cheap,
- they don’t get oily at room temperature.

Foods rich in sugar & foods with high glycemic index are bad for your vision
Avoid all foods that can cause a blood sugar spike.
Sugar and refined flour are the most common foods that can cause blood sugar spike (5).
Also, avoid sweets, sweetened drinks, energy drinks, sauces, dressings, and every other food that it’s rich in sugar.
Moreover, avoid baked goods. In most cases, refined flour is used. Prefer whole wheat flour.
Finally, fruits are good foods for your eye health, despite the sugar content. Fructose won’t spike blood sugar. Due to the fiber in fruits. Dietary fiber keeps blood sugar levels steady.
Extra salt may be bad for your eye health
