What Is A Healthy Diet? Follow 3 basic principles of healthy eating/sound dietary planning! Healthy does not have to be deprivation & misery. • Variety • Balance • Moderation
Variety • Eat many different foods (within a food group) • Eat many different colors • This will ensure sufficient intake of most nutrients • Inclusion of phytochemicals, thought to block the process of cancer (T 2.1)
Balance • Select foods from the SIX food groups • Grains • Milk & other dairy • Meat or meat substitutes & beans • Vegetables • Fruits • Oils & sweets
Moderation • Control portion size • Plan your daily intake to avoid over consumption of certain nutrients • Avoid over indulging in foods high in sodium, fat & empty calories • NO “good food” or “bad food”
Nutrient Density • Comparison of vitamin & mineral content to number of kcals • Empty calories provide many kcalories but few nutrients
Energy Density (T 2.2) • Energy dense foods have many calories but do not weigh a lot • Nuts, cookies, fried foods • Low-energy-density foods have fewer calories for their weight & also contributes to satiety • Foods with more water and dietary fiber • Fruits, vegetables, oatmeal
Desirable State of Nutritional Health AVOID MALNUTRITION • Intake meets body’s needs • Body has a small surplus • MD visit?
Undernutrition • Intake is below body’s needs • Stores used • Health declines • Clinical symptoms • Skin, hair, nails, tongue, eyes • Bruising, fatigue
Overnutrition • Intake exceeds body’s needs • Short term, few symptoms • Long term, serious conditions • Clinical symptoms • Obesity • CV • DM • HTN
