Fiber Is A Valuable Nutrient

n1 training

 

 

 

There are two main classifications of fiber, soluble and insoluble, and each play important roles in maintaining gut health and assisting your body in elimination of waste.  You are no doubt familiar with the importance of your macronutrients (proteins, carbohydrates, and fats) for health, performance, and body composition.  But your fiber intake, and the type of fiber, can be equally as important for optimizing your health and recovery. 

Types

Soluble fiber dissolves in liquid and digestive fluids and turns into a gel-like consistency. This types of fiber are referred to as “prebiotics” and is fed upon by the bacteria in your gut.  It is vital to promoting a healthy gut flora balance as the bacteria in your intestinal microbiome are responsible for breaking down what you consume so that your body can effectively absorb them. Types of soluble fibers:

  • Fructans
    • Inulin
    • FOS (fructooligosaccharides)
    • Oligofructose
  • Galactan
  • Pectin
  • Beta-glucan

Insoluble fiber is responsible for adding volume to bowel movements and aiding in motility.  It binds with bile in the intestinal tract to help transport toxins out of the body through excretion.  A lack of insoluble fiber decrease your body’s ability to export toxins through the intestines, leading to re-absorption of the very materials your body is trying to get rid of. A lack can also lead to irregularity or even digestive distress if you are not excreting the toxins your body is attempting to eliminate.

Recommendations

The general recommendation for consumption is 25-30g per day.  However, that does not account for the drastic potential variation in an individual’s food consumption and microbiome needs.  A safe starting place is about 15g per 100g of carbohydrates. This should be quite easy if you are consuming 1-2 servings of vegetables with each of your whole-food meals, which is something we highly recommend to all of our students and clients.  By eating a serving of fibrous vegetables along with colored varieties at each meal you should have no trouble reaching a healthy amount of soluble and insoluble fiber in your diet.

Program Plans

After taking our training analysis quiz, you’ll have a long-term plan constructed for you. Your plan will consist of several Phases. Each Phase will present you with a few suggested programs to pick from. Each time you complete a program, you’ll move on to the next Phase and a new set of programs to select from.

This allows flexibility in the split and type of program you can choose, while we strategically periodize the stimulus you’re getting to keep making consistent progress without neglecting any weak links.

For example, a long-term plan with the goal of muscle gain will still occasionally include systemic conditioning or dedicated local metabolic work to keep your recovery capacity high (so you can grow and perform better during your hypertrophy-focused programs).
