Question

myth / claim nutrient(s) involved \carbs make you fat.\ \you only need protein if you lift weights.\ \vitamin c prevents colds.\ \all fats are bad.\ \you can drink soda instead of water if youre thirsty.\

Explanation:

• For "Carbs make you fat": Carbohydrates (carbs) are the nutrient involved. Excess calorie intake (not just carbs) leads to weight gain.
• For "You only need protein if you lift weights": Protein is the nutrient. Protein is essential for all body functions like tissue repair, enzyme production etc., not just for weight - lifters.
• For "Vitamin C prevents colds": Vitamin C is the nutrient. While it may boost immunity slightly, it doesn't prevent colds.
• For "All fats are bad": Fats (lipids) are the nutrient. Some fats like unsaturated fats (in avocados, nuts) are healthy.
• For "You can drink soda instead of water if you're thirsty": Water is the main nutrient (soda has water but also added sugars etc.). Water is essential for hydration without the negative effects of soda's additives.

Answer:

1. Carbohydrates
2. Protein
3. Vitamin C
4. Fats
5. Water
