Absolutely, nutrition plays a crucial role in enhancing performance. It's important to understand that behavioral tools form the foundational layer of all tools for mental health, physical health, and performance. These are specific actions we take or avoid, like viewing morning sunlight or avoiding caffeine too late in the afternoon.
The next layer is nutrition. No amount of supplements or compounds can compensate for poor nutrition, at least not for very long. While many supplements are not simply food supplements, it's not to say that you can live on supplements.
So, in essence, behavioral tools are the bedrock of all mental health, physical health, and performance, and on top of that, I would place nutrition. It's also worth noting that what constitutes good nutrition can vary from person to person, given the wide array of food choices and nutritional programs available.
