Three factors that are the foundation of a healthful eating plan?

A healthful eating plan is built on three key factors: balance, variety, and moderation. Balance ensures that the diet includes appropriate proportions of macronutrients—carbohydrates, proteins, and fats—alongside essential vitamins and minerals. Variety prevents dietary monotony and promotes a wider intake of nutrients by incorporating different food groups and types. Lastly, moderation helps manage portion sizes and limits excessive intake of unhealthy foods, supporting overall health and well-being.
