More than half of all adults over 70 have cataracts or have undergone cataract surgery to remove them.
Cataracts are a normal aspect of growing older. Even with the best health, most people will eventually develop cataracts.
What are cataracts?
Cataracts block vision by making the lens of the eye opaque and difficult to look through, causing cloudy vision.
Cataracts are the most common cause of vision loss and blindness in the world.
While there is no non-surgical cure for cataracts, according to studies, several foods and nutritional supplements appear to slow the progression of this sight-threatening eye condition in some people.
What causes cataracts?
The lens inside the eye is made up of proteins. Oxidative stress damages proteins and enzymes in the lens, leading to cataract formation, according to a study published in Nutrients (2019).
Oxidative stress is caused by an imbalance between free radicals, which are atoms that kill cells in your body, and antioxidants, which reduce them. When you don’t have enough antioxidants to neutralize the free radicals in your body, you get oxidative stress
Free radicals can come from a variety of sources, including unhealthy meals. Eating a high-antioxidant diet, according to some optometrists, can help delay the onset of cataracts and even reduce your risk of developing cataracts in the first place.
Foods to avoid for good vision
If you want good vision, you should live a healthy lifestyle, including both exercise and watching the food you eat.
Living healthy includes activities such as exercising, eating a balanced diet, and making well-informed health decisions. Soft drinks, processed or fried foods, and sugary snacks should be avoided to the greatest extent possible.
Unhealthy foods and beverages have been related to a higher incidence of cataracts, even in children.
Furthermore, lowering your sodium intake is a smart idea, as research published in the American Journal of Epidemiology (2000) indicated that a high salt intake increases the risk of cataracts.
