Nutrition Foundation
Proper nutrition is fundamental to health, performance, and longevity. Understanding macronutrients, micronutrients, and food quality enables informed dietary choices.
Macronutrients Deep Dive
Protein: Amino acids build and repair tissue. Essential for muscle growth, recovery, and immune function. Daily needs: 0.8-1.6g per kg body weight depending on activity.
Carbohydrates: Primary energy source. Whole grains provide sustained energy and fiber. Refined carbs often offer empty calories.
Fats: Essential for hormone production, vitamin absorption, brain health. Prioritize unsaturated fats from nuts, seeds, fish, oils.
Essential Micronutrients
Vitamins: Organic compounds required for countless bodily functions. Deficiencies cause serious health problems.
Minerals: Inorganic elements supporting bone health, muscle function, nerve transmission. Calcium, magnesium, potassium critical.
Phytonutrients: Plant compounds with antioxidant and anti-inflammatory properties. Found in colorful vegetables and fruits.
Practical Nutrition Guidelines
Whole Foods: Prioritize minimally processed foods. Whole foods provide nutrient density and satiety.
Variety: Different foods provide different nutrients. Eat the rainbow for comprehensive micronutrient intake.
Portion Control: Even healthy foods in excess cause problems. Awareness of portion sizes prevents overeating.
Hydration: Water is essential for every bodily function. General guideline: half body weight in ounces daily.
