- A type of polyunsaturated fatty acids (PUFAs) that must be obtained
through the diet because it cannot be made by the human body
Why are omega-3 fatty acids important?
- Omega-3 fatty acids may be important in preventing many health
problems, including heart disease, rheumatoid
arthritis, and cancer. They also
play a role in improving mood and sharpening
memory.
What foods are good sources of omega-3 fatty
acids?
- Cold water fish are the highest source of EPA and DHA omega-3 fatty acids which have been shown to be the most effective in reducing cardiovascular disease risk. Other foods contain these fatty acids as well, however, in smaller
amounts. The current recommendations are to have 7
to 11 grams of omega-3 fatty acids each week.
