Omega-3 may protect against skin cancer

Taking omega-3 fish oils could help to protect against skin cancer. Results of the American Journal of Clinical Nutrition study found that taking a regular dose of fish oils boosted skin immunity to sunlight. Specifically, it also reduced sunlight-induced suppression of the immune system, known as immunosuppression, which affects the body's ability to fight skin cancer and infection. This was the first time the research had been carried out on humans.

Patients who volunteered for the trial took a 4g dose of omega-3, which is about one and a half portions of oily fish, daily and were then exposed to the equivalent of either 8, 15 or 30 minutes of summer midday sun in Manchester using a special light machine. Other patients took a placebo, before being exposed to the light machine. Immunosuppression was 50% lower in people who took the supplement and were exposed to 8 and 15 minutes of sun compared with people who did not take the supplement.
