HUMAN NUTRITION

Detailed explanation-1: -Nutrient needs vary with age, gender, and activity level.

Detailed explanation-2: -Although the recommended breakdown of carbohydrate, protein, and fat are the same for both genders, because men generally need more calories, they also require higher total intake of each of the macronutrients. Women need fewer calories than men, but in many cases, they have higher vitamin and mineral needs.

Detailed explanation-3: -Older adults generally have lower calorie needs, but similar or even increased nutrient needs compared to younger adults. This is often due to less physical activity, changes in metabolism, or age-related loss of bone and muscle mass.

Detailed explanation-4: -The total number of calories a person needs each day varies depending on a number of factors, including the person’s age, sex, height, weight, and level of physical activity. In addition, a need to lose, maintain, or gain weight and other factors affect how many calories should be consumed.
