2. Adult 18 -64 Womens issues More prevalent in females are osteoporosis -80 % of cases autoimmune cases- 75 % of cases disproportionate number of cases of -diabetes mellitus -irritable bowel syndrome -psychiatric conditions (e.g. depression)

3. Adult 18 -64 Womens issues heart disease # 1 killer-estrogen delays onset of heart disease but post-menopausally when estrogen drops then females catch up in a hurry to men in terms of numbers of those with clinically significant heart disease -diet low in fat and saturated fat, rich in fruits and vegetables (7-8 servings daily) and whole grains and not excessive in whole calories combats heart disease in females

4. Adult 18 -64 Womens issues cancer- # 2 killer (lung, breast, then colorectal) -dietary reduction of cancer risk: -eat 7-8 servings of fruits and vegetables daily -phytoestrogens in soy believed to help though isoflavones in one animal study increased cancer rate obesity- apparently greater in females leading to greater risk of type 2 diabetes

8. Seniors (65 and older) -80 % of seniors have at least one of arthritis, hypertension, heart disease or diabetes -loss of lean body mass and increase in adipose tissue leading to progressive decrease in basal metabolic rate -loss of teeth, periodontal disease and decrease in jaw bone mass (osteoporosis), in some there is decreased saliva (may be medication related)
