One more reason to take your omega-3s: these essential fatty acids can help prevent dry eye syndrome, a painful condition in which not enough tears are produced to keep the eyes lubricated. Dry eye syndrome affects about eight million Americans, mostly women, and research has demonstrated that a high daily intake of omega-3 fatty acids can protect against its uncomfortable symptoms. To support general eye health, try increasing your intake of oily, cold-water fish such as wild Alaskan salmon, mackerel, herring and black cod, as well as walnuts and freshly ground flaxseed. If you suffer from dry eye syndrome, you may also want to consider supplementing with a high-quality fish oil product.
