According to WebMD, below are foods old people should eat regularly to prevent blindness:
1. Sunflower Seeds and Nuts
Accordingly to WebMD, Half of the daily value of vitamin E that the USDA advises for adults can be found in only one ounce of these seeds or almonds. Vitamin E, along with other nutrients, has been shown in big research to help delay the progression of age-related macular degeneration (AMD). Furthermore, it has the potential to protect against cataracts. Vitamin E can also be found in abundance in hazelnuts, peanuts (which are technically legumes), and peanut butter.
2. Dark, Leafy Greens
Greens such as kale, spinach, and collards, for instance, have high concentrations of vitamin C and vitamin E. The carotenoid antioxidants lutein and zeaxanthin are also present. Consuming these vitamin A plant sources can help prevent age-related macular degeneration and cataracts. Most Westerners' diets typically lack sufficient amounts of these foods.
3. Salmon
Omega-3 fatty acids DHA and EPA are essential for healthy retinal function. Both can be found in seafood in general, but fatty fish in particular, such as salmon, tuna, and trout. Moreover, omega-3s appear to prevent age-related macular degeneration and glaucoma. Dry eyes have been linked to low levels of these fatty acids.
4. Sweet Potatoes
Beta-carotene, a type of vitamin A that aids with night vision, is abundant in orange fruits and vegetables such as sweet potatoes, carrots, melons, mangos, and apricots. Furthermore, one sweet potato provides almost half of your daily vitamin C and E requirements.
5. Lean Meat and Poultry
The antioxidant pigment melanin is produced from vitamin A, which zinc transports from the liver to the retina. Oysters are the best dietary source of zinc since they contain the highest concentration of zinc per serving. Various cuts of beef, hog, and chicken (including dark and white meat) are all nutritious options.
6. Beans and Legumes
Are you looking for a vegetarian, low-fat, high-fibre solution to maintain nighttime clarity of vision and delay the onset of AMD? In addition to black-eyed peas, kidney beans, and lentils, chickpeas are also a good source of zinc. You can also use a can of baked beans.
