1. To maintain good health, total fat intake should be reduced to 30% or less of calories. Saturated fat intake should only account for 10% (one third of fat calories). Salt and alcohol intake also should be limited.

2. Nutrition plays a role in cardiovascular disease, some malignancies, adult-onset diabetes, osteoporosis, alcoholism, and recovery from major injury.

3. Malnutrition can weaken the immune system, impair healing following surgery or injury, lessen mobility, and reduce mental capabilities and function. It is common in older adults.

4. Foods to be avoided include whole milk and dairy products (ice cream, cheese, butter); commercially baked goods (cookies and crackers); hot dogs, ham, and cold cuts; and oils, gravies, and salad dressing.

5. Dietary fat content composed primarily of monounsaturated fat (eg, olive oil) and polyunsaturated fat (eg, canola, corn and fish oils) may be associated with a lower incidence of cardiovascular disease.
