Here's a quick and easy way to dramatically lower your risk of the top age-related sight disorder... go fishin'!

We've known for years that fish oil plays a key role in eye health, but the latest studies show that omega-3 fatty acids can actually reduce your risk of age-related macular degeneration by around a third.

That's the single biggest cause of blindness in folks over 55, afflicting around 30 million people around the world. Some estimates say those numbers will triple by 2025, which isn't as far off as it sounds.

There are two kinds of AMD, but without getting technical on you we can call them "wet" and "dry." That's because one involves leaking blood vessels, while the other doesn't.

Fortunately, fish oil can reduce your risk of both conditions. A study in the American Journal of Clinical Nutrition found that consuming extra omega-3 fatty acids can reduce your risk of wet AMD by 35 percent, and the dry one by 32 percent.

This supports an Australian study published last year, which found that omega-3 fatty acids can reduce the risk of AMD by around 38 percent – and that people who ate fish at least twice a week had the lowest risk.

This shouldn't be a surprise to anyone. One of the main fatty acids in fish oil is docosahexaenoic acid, or DHA. One of the main fatty acids in our retina is... that very same DHA.

Our brains are also packed with the stuff, which is why it's so important to make sure you get plenty of omega-3 fatty acids every day.

In addition to eye and brain health (as if that's not enough), these essential oils can also help avoid some cancers, fight off diabetes and slash your risk of heart disease.

You don't really have to catch your own fresh fish to enjoy the benefits of omega-3 fatty acids. You don't even have to eat fish (but it helps). If you don't like seafood or worry about mercury levels, then the catch of the day for you is an omega-3 supplement.

Some of them may leave a fishy aftertaste – or the so-called "fish burps" – so experiment until you find one you like. After all, there's nothing fishy about great health!
