The Science of Nutrition | How Food Fuels Your Body
1. Macronutrients: The Energy Trio
Proteins (20-30% of diet) – Builds muscles, repairs tissues (chicken, lentils, Greek yogurt).
Carbohydrates (45-55%) – Primary fuel source (quinoa, sweet potatoes, oats).
Fats (25-35%) – Supports brain function and hormones (avocados, nuts, olive oil).
2. Micronutrients: The Silent Health Guardians
Vitamin D – Strengthens bones and immunity (sunlight, fatty fish).
Magnesium – Regulates nerves and muscles (spinach, almonds, dark chocolate).
Omega-3s – Reduces inflammation (salmon, chia seeds, walnuts).
3. Phytonutrients & Antioxidants
Found in colorful fruits/veggies, these combat oxidative stress (blueberries, kale, beets).

40+ FAQs on Diet & Nutrition
1. What is the best diet plan for overall health?
A balanced diet rich in whole foods—lean proteins, complex carbs, healthy fats, and plenty of fruits/vegetables—supports long-term wellness.
2. How many meals should I eat per day?
There’s no one-size-fits-all answer. Some thrive on 3 meals, others prefer 5-6 smaller meals. Listen to your body’s hunger cues.
3. Are low-carb diets healthy long-term?
While effective for short-term weight loss, extreme low-carb diets may lack fiber and essential nutrients. Moderation is key.
4. What are the best protein sources for vegetarians?
Lentils, chickpeas, tofu, quinoa, Greek yogurt, and nuts/seeds provide ample plant-based protein.
5. How much water should I drink daily?
Aim for 2-3 liters (8-10 glasses) daily, adjusting for activity level and climate.
6. Is intermittent fasting beneficial?
Yes, when done correctly (e.g., 16:8 method), it may improve metabolism and blood sugar control.
7. What’s the role of fiber in a healthy diet?
Fiber aids digestion, lowers cholesterol, and keeps you full. Aim for 25-30g/day (whole grains, veggies, legumes).
8. Are artificial sweeteners safe?

Good: Unsaturated fats (avocados, olive oil, nuts).
Bad: Trans fats (fried foods, processed snacks).
11. Can I get enough omega-3s without fish?
Yes! Flaxseeds, chia seeds, walnuts, and algae oil are great plant-based sources.
