A study from Oklahoma State University shows that flaxseeds help to lower cholesterol but do not strengthen bones.

At menopause, a woman's body markedly reduces its production of estrogen, weakening bones and increasing risk for heart attacks. Flaxseeds are a rich source of plant estrogens called lignins and omega-3 fatty acids. Both help to prevent heart attacks. Women took either 40 grams of ground flaxseed or ground wheat daily for three months. All subjects received 1,000 mg calcium and 400 IU vitamin D daily. The flaxseed lowered blood total cholesterol by six percent, LDL cholesterol by 4.7 percent and triglycerides by 12.8 percent, while wheat did not affect blood cholesterol levels. Markers of bone formation and resorption were not affected by either the flaxseeds or the wheat.

Flaxseed improves lipid profile without altering biomarkers of bone metabolism in postmenopausal women. Journal of Clinical Endocrinology and Metabolism, 2002, Vol 87, Iss 4, pp 1527-1532.
