I love beer. But I think most people would agree that drinking too much alcohol is not good for general health, let alone athletic performance. You don't need to be an MD to understand this point. But what about moderate drinking? Obviously there are calories to be concerned about, and dehydration from from alcohol can have a significant impact on how you feel and perform. So if you balance your calories, and be sure to stay hydrated, will you be free from negative effects of alcohol?
For me, the answer is no. I'm generally an anxious person, who can be prone to stressing out about things that don't require such an intense response. What I've found is that, for a day or so after having more than a drink, my stress and anxiety is heightened to an uncomfortable level. Put a couple of drinks in me, and I wake up super early (generally with a head ache) worrying about work or family, for no great reason.
What I'm beginning to understand is the true impact that food has on your body. It goes way beyond fat, carbs, and protein. The food you eat (and drink) has an effect on all of your body's systems. This means that eating the wrong things can have a much broader effect than just making you fat. It also means that, just because you're skinny, you're not necessarily healthy and functioning optimally.
A point of irony: this blog is called "paleo," yet one of the books I recommend on the right is a book promoting a vegan diet. I really enjoyed the book
Thrive: The Vegan Nutrition Guide to Optimal Performance in Sports and Life for a number of reasons. First, it is direct and to the point, and full of applicable knowledge. You can read this book and immediately make changes resulting in a positive impact on your life. Second, it is chock full of recipes - although not necessarily paleo friendly ones. But if you are looking to break away from the high-carb, processed foods that many people eat, these recipes offer a unique and tasty alternative.
Most important, however, is the point that the author Brendan Brazier makes about stress. We are constantly bombarded by stress: at home, at work, at the gym, on the trail. Most of the things that cause us stress are pretty obvious. What is not so obvious, however, is the fact that many of us stress our bodies from the inside out. The process of digesting food is a stress on the digestive system. Brazier argues that we should aim to consume low-stress (easily digestible) foods with the greatest nutritional punch. I agree wholeheartedly.
There is a definite gap in my current knowledge. I understand that some foods are harder to digest than others, thereby putting the body under more stress. However, there are also foods that can make you feel more stressed
mentally, in the same way that a bit of alcohol will leave me feeling anxious for a few days. There are complex chemical things going on here that I don't really understand. Fortunately, there are people smarter than myself who've done far more diligent research on the subject.
