Nutritional choices can play a significant role in maintaining the health of organs, including the eyes. Further, due to the arrangement of vessels behind the eyes, issues with heart health can affect the eyes. So, choosing foods that are not heart-friendly and have low nutritional value can restrict the vessels from transporting vital nutrients and oxygen to the eyes. Such eating habits can degrade eye function, which may lead to problems with vision. Foods to avoid French fries One often enjoys fried items at a fast food joint. But such food can be extremely unhealthy. Many batches of french fries are made using the same oil and reheated multiple times before being served. While this is cost-effective for the fast food joint, the fries undergo molecular changes, which increases the harmful fat content. These fats are known to affect the health of organs, including the heart and eyes. Further, fried foods contain free radicals that cause oxidative stress to the body and subsequently affect eye health. Margarine Margarine is often deemed the healthier version of butter as it is made using vegetable oils. However, margarine is rich in trans fats, which are known to increase bad cholesterol levels in the body.
