New research shows that omega-3 fatty acids play a role in increasing bone density both in adolescents and in the elderly, thereby helping prevent osteoporosis.  If you have read my Omega-3 article, you know that I recommend supplementing with omega-3's for everyone. Other areas of benefit include: coronary heart disease, stroke, autoimmune disorders, inflammatory bowel disease, depression and other mood disorders, and cancers of the breast, colon, and prostate

Also, remember that  your ratio of omega-3's to omega 6's should be close to 1-to-1, and that most Americans are about 1-40!  Most of us need, therefore, to limit our omega-6 fats by not using vegetable oils (except olive oil) and by eating fewer grains.
