We've gotten used to taking pills for everything that ails us, but medications have side effects and cost money. Harvard Health Letter takes a look pills.

Here's a brief look at the conditions and treatments.

Arthritis

There's a good chance that losing weight will make arthritis less painful. Combine weight loss with exercise and you may have less pain and more mobility. Even for those who don't need to lose weight, exercise that doesn't put "load" on the joints reduces pain.

Cholesterol

Your LDL level may drop by 5% or so if you keep foods high in saturated fat off the menu. Additional soluble fiber may reduce LDL levels as well. So can margarines fortified with sterols.

Cognitive decline

Memory training and other "brain exercises" seem to help healthy older people stay sharp. But physical exercise may benefit the brain more than mental gymnastics.

Depression
Studies have shown that regular physical activity can have a potent antidepressant effect.

Diabetes

Regular physical activity is a powerful brake on blood sugar levels as well, because exercised muscle becomes more receptive to the insulin that helps it pull sugar in from the bloodstream. Eating fewer sweets and easy-to-digest carbohydrates also helps control blood sugar levels.

High blood pressure

Losing weight, getting more exercise, and eating less sodium all lower blood pressure.

Osteoporosis

Weight-bearing exercise puts stress on bones, and bone tissue reacts by getting stronger and denser, fending off osteoporotic processes. Extra vitamin D and calcium top the list of dietary recommendations.
