Final Answer:
Good nutrition means getting enough macronutrients and micronutrients to keep the body healthy and functioning properly (Option 1).
Step-by-step explanation:
A balanced diet is essential for good nutrition. Macronutrients, including carbohydrates, proteins, and fats, provide the energy required for daily activities. Micronutrients, such as vitamins and minerals, play crucial roles in various physiological processes. To determine the nutritional adequacy, one must ensure the intake of these components meets the recommended daily allowances (RDAs).
Macronutrient needs vary based on factors like age, sex, and activity level. Carbohydrates should contribute about 45-65% of total daily calories, proteins 10-35%, and fats 20-35%. Micronutrient requirements, measured in micrograms (µg) or milligrams (mg), differ for each nutrient. For example, Vitamin C's RDA is 90 mg for men and 75 mg for women. Insufficient intake can lead to deficiencies, affecting bodily functions negatively. Conversely, overconsumption may lead to health issues like obesity or nutrient toxicity.
Fast food, often high in unhealthy fats, sugars, and low in essential nutrients, fails to provide adequate nutrition. Relying on such diets can lead to deficiencies and contribute to various health problems. Therefore, achieving good nutrition involves making informed choices about the quality and quantity of macronutrients and micronutrients in one's diet, ensuring the body functions optimally and stays disease-free (Option 1).
