Eating your way to good vision is more effective than taking supplements says December’s Berkeley Wellness Letter [1]. While many nutrients promote eye health – yes, the beta carotene in carrots still tops the list—they are most effective when ingested through food.

This is a prime example of nutritional multitasking. The same diet that's said to promote heart health and prevent certain cancers is also linked to healthy eyes. Here's a summary of Berkeley's summary:

• Fruits, veggies and whole grains: Leafy greens may prevent cataracts and colorful produce contains the most carotenoids [2].
• Healthy fats: Omega-3 fats may protect eyes so choose fish over French fries.
• Zinc: The mineral may protect eye tissue from light and inflammation. Zinc can be found in a wide range of food from meat to wheat germ.
