Final answer:
The amount of food from each food group needed daily depends on factors such as age, gender, and physical activity level. Using the MyPlate guide, a balanced diet is achieved through adequacy, balance, calorie control, moderation, and variety, and must be personalized to meet individual nutritional needs.
Step-by-step explanation:
The amount of each of the food groups needed for an individual person each day depends on several factors, including age, gender, and physical activity level. These aspects influence the total number of calories and nutrients that an individual requires. For instance, energy needs for athletes may be higher due to increased energy expenditure from physical activities. Additionally, dietary preferences, while not necessarily a direct nutritional requirement, can affect the choice of items within a food group, such as opting for plant-based proteins over animal proteins.
According to the MyPlate approach developed by the USDA, a balanced plate should consist of fruits and vegetables covering half of the plate, whole grains making up one-quarter, and protein the remaining quarter, with an emphasis on low-fat or non-fat dairy products. Achieving a balanced diet includes ensuring adequacy, balance, calorie control, moderation, and variety to meet an individual's unique energy and nutritional requirements, which vary with age, sex, and activity levels.
It is important to understand that there is no single food that provides all the necessary nutrients, and therefore consuming a variety of foods within each group is essential for a healthful diet. When planning a healthy diet, individuals must consider their age, gender, and level of physical activity to tailor their nutritional intake and ensure that their diet meets their personal energy and health needs.
