Insight into nearsightedness in kids

More U.S. kids than ever are nearsighted — it affected about 25% in the early ’70s and by 2000, it hit 42%. A lot of the blame is placed on screen time. Kids now spend an average of 7.5 hours a day staring at a digital image only a few inches from their faces. No wonder the world seems blurry when they finally look up.

But there might be another culprit staring us right in the eye: Excess saturated fat in kids’ diet and too few omega-3s. A study in the British Journal of Ophthalmology looked at 6 to 8 year olds and found that kids with the highest amount of saturated fats in their diets were the most likely to become nearsighted, those with the highest levels of omega-3 fatty acids were least likely. Why? Over the long term, saturated fats contribute to restricted blood flow, even in the eye, while omega-3s increase it in a vascular layer that delivers nutrients and oxygen to the eye, preventing nearsightedness. Omega-3s are found in salmon, ocean trout, avocados, sardines, anchovies and herring, flaxseed, chia seeds and walnuts.

Other important nutrients for kids’ — and adults’ — eyes: foods rich in vitamins C and E, zinc, lutein and zeaxanthin. They’re in citrus, berries, tomatoes, broccoli, red and green peppers, almonds, leafy green vegetables and colorful fruits.

So do your kids (and yourself) a favor and upgrade your diets to include these healthy, tasty foods, and ditch red and processed red meats, fried foods and saturated fat-loaded sauces. You’ll see the rewards!
