Good nutrition should primarily be based on what?

Good nutrition should primarily be based on outcomes and results because this approach focuses on the effectiveness of dietary choices in achieving health and fitness goals. By emphasizing outcomes, individuals can assess the impact of their nutrition on factors such as weight management, muscle development, overall energy levels, and overall health. This evidence-based perspective allows for adjustments to be made based on personal progress and scientific research, ensuring that nutritional strategies are tailored to help individuals reach their specific goals.

Other options, such as theoretical approaches, market trends, or the popularity of foods, may not provide a solid foundation for making nutritional decisions. While theories can guide our understanding of nutrition, they do not necessarily reflect real-world applications or individual results. Market trends and popularity often fluctuate and can be influenced by marketing rather than sound nutritional science. Focusing on actual outcomes ensures that individuals are making informed choices that directly align with their health and fitness needs.
