What do recreational athletes need to focus on regarding nutrition?

Recreational athletes should focus on micronutrient deficiencies because these nutrients play a crucial role in overall health, energy production, muscle function, and recovery. Adequate intake of vitamins and minerals is essential for optimal performance and can help prevent fatigue and illness, which could hinder their ability to train and compete. For example, deficiencies in vitamins like B12, vitamin D, or minerals such as iron and calcium can lead to decreased energy levels and impaired physical performance. Ensuring an adequate dietary intake of these micronutrients will help recreational athletes maintain good health and improve their athletic capabilities.

The other options do not address the holistic nutritional needs of recreational athletes. Calorie restriction can lead to energy deficits that may negatively impact performance and recovery. While building muscle mass is important for some athletes, a high-protein diet may not be necessary for recreational athletes who engage in varied activities. Lastly, reducing carbohydrate intake for weight loss can result in inadequate energy for training and may counteract performance goals. Thus, focusing on micronutrients provides a more balanced and effective approach to nutrition for recreational athletes.
