WHAT SHOULD I EAT?
In plain language, base your diet on garden vegetables (especially greens), meats, nuts and seeds, some fruit, little starch, and no sugar. That is about as simple as we can get.
Many have observed that keeping your grocery cart to the perimeter of the grocery store while avoiding the aisles is a great way to protect your health. Food is perishable. The stuff with long shelf life is all suspect.
If you follow these simple guidelines, you will benefit from nearly all that can be achieved through nutrition.
THE CAVEMAN OR PALEOLITHIC MODEL FOR NUTRITION
Modern diets are ill suited for our genetic composition. Evolution has not kept pace with advances in agriculture and food processing, resulting in a plague of health problems for modern man. Coronary heart disease, diabetes, cancer, osteoporosis, obesity, and psychological dysfunction have all been scientifically linked to a diet too high in refined or processed carbohydrate.
The caveman model is perfectly consistent with CrossFit’s prescription.
WHAT FOODS SHOULD I AVOID?
Excessive consumption of high-glycemic carbohydrates is the primary culprit in nutritionally caused health problems. High-glycemic carbohydrates are those that raise blood sugar too rapidly. They include rice, bread, candy, potato, sweets, sodas, and most processed carbohydrates.
Processing can include bleaching, baking, grinding, and refining. Processing of carbohydrates greatly increases their glycemic index, a measure of their propensity to elevate blood sugar.
WHAT IS THE PROBLEM WITH HIGH-GLYCEMIC CARBOHYDRATES?
The problem with high-glycemic carbohydrates is that in excess they give an inor- dinate insulin response. Insulin is an essential hormone for life, yet acute, chronic elevation of insulin leads to hyperinsulinism, which has been positively linked to obesity, elevated cholesterol levels, blood pressure, mood dysfunction, and a Pandora’s box of disease and disability.
Research “hyperinsulinism.” CrossFit’s prescription is a low-glycemic diet (and relatively lower in total carbohydrate quantity) and consequently severely blunts the insulin response, yet still provides ample nutrition for rigorous activity.
