- Incorporate five major food groups: grains, fruits, proteins, vegetables, and dairy.
Role of Phytochemicals
- Phytochemicals have the potential to reduce the risk of cancer and cardiovascular diseases.
Understanding Functional Foods
- Functional foods provide additional health benefits beyond traditional nutrients.
- Example: Tomatoes contain lycopene, classifying them as functional foods.
Proportionality in Diet
- Balance nutrient-dense foods (fruits, vegetables, whole grains) with limited intake of foods high in fats, sugars, and salt.
Nutrient Density Defined
- Nutrient density reflects the nutritional value of food in relation to its calorie content.
- High nutrient density indicates more vitamins and minerals per calorie.
Empty Calorie Foods
- These foods are high in fat and/or sugar but low in essential nutrients.
Concept of Moderation
- Moderation involves being mindful of portion sizes and planning meals to avoid excessive intake of certain nutrients.
- Focus on reducing consumption of animal fats, added sugars, salt, and alcohol.
Energy Density Explained
- Energy density refers to the calorie content of food relative to its weight.
- High energy-density foods are calorie-rich with low physical weight.
Examples of Energy Density
- High energy dense: nuts, cookies, fried foods.
- Low energy dense: fruits, vegetables, oatmeal (lots of water content).
Energy Density Categories
- Very low energy dense foods (less than 0.6 kcal/gram): lettuce, tomatoes, strawberries, broccoli, salsa, grapefruit, melon.
- Low energy dense foods (0.6 - 1.5 kcal/gram): whole milk, oatmeal, broiled fish, bananas, fat-free yogurt.
- Medium energy dense foods: eggs, ham, pumpkin pie, bagels, raisins, rice cakes.
