Essential Nutrition

Food Quality and Quantity


These two main categories are fundamental to healthy nutrition. Food quality refers to what kind of food you are putting in your body. This is addressed with the Paleolithic (Paleo) diet. Food quantity refers to how much of that food are you putting in your body. Here at FunFit, we believe strongly that nutrition is one of the foundations of our fitness and health.

What Should I Eat?


In plain language, base your diet on garden vegetables, especially greens, lean meats, nuts and seeds, little starch, and no sugar. 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 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 humans. 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. Search “Google” for Paleolithic nutrition, or diet. The return is extensive, compelling, and fascinating. The Caveman model is perfectly consistent with the CrossFit Method prescription.

What Foods Should I Avoid?


Excessive consumption of high-glycemic carbohydrates is thought to be a 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, soft drinks, 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 they give an inordinate 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” on the Internet. There’s a gold mine of information pertinent to your health available there. The CrossFit prescription is a low-glycemic diet and consequently severely blunts the insulin response.

How much should I eat?


Eat when you’re hungry; stop when you’re satisfied – not full. If you’re eating ‘real’ food then your body’s signalling system has a chance to reset to where it can give you accuracy. Fake food throws out the balance, resulting in bad signalling and potentially overeating.
