Fibre and all its magic powers

Fibre and all its magic powers

Health
  What is Fibre? This term fibre is thrown around in the media, in health blogs, magazines and celebrity diets but what actually is it? I’m so glad you asked… Fibre is the edible portion of any plant-based food. Even though fibre is classified as a nutrient, it resists digestion and absorption in the small intestine, and it ferments either partially or completely in the large intestine. Fibre has a unique role in the maintenance of overall gut health and it also is responsible for other sneaky tricks which many are unaware of. Fibre is protective against colon cancer, high cholesterol, coronary heart disease, type two diabetes, obesity and diverticular disease. Let’s explore fibre’s activities in the body and how it is able to be protective against so many conditions.…

(I would like to credit information in this week’s blog post to Professor Manohar Garg of the University of Newcastle) There is much debate around this hot topic and justifiably so. To the common person with little nutritional knowledge, carbs and fats are what make you put on weight right? Protein takes longer to break down and keeps you fuller for longer and therefore it must be the answer. Unfortunately, it is not that simple. Before we delve into this discussion lets take a few steps backwards and define the key components. What are Proteins Amino acids are the building blocks of protein and are made up of carbon, hydrogen, oxygen, nitrogen and sulphur. Percentage wise, 43% of our body’s protein is in our muscle, 15% in our skin and…

Glycemic Index and Glycemic Load: The Interplay Between the Two

Glucose, commonly known as blood sugar is a monosaccharide, which means it is chemically the simplest form of sugar. Other monosaccharides include fructose and galactose. We then have disaccharides including lactose, which are two sugar molecules, and polysaccharides which are three or more sugar molecules. Both of which break down into monosaccharides during metabolism. When we eat food, it goes down into our stomach, where many digestive enzymes start to break it down. After a while, the partially broken-down food travels to the small intestine where it is further broken down. One of the molecules carbohydrates are broken down into is glucose. From the small intestine, glucose is absorbed into the bloodstream. As glucose is absorbed into the blood stream, blood glucose levels rise. The glycemic response refers to how…

What is Carbohydrate Loading? Carbohydrate loading or carbo-loading, is a term used to describe a nutrition technique used by endurance athletes in an attempt to prolong optimal athletic performance and delay the onset of fatigue, or, ‘hitting a wall’. The Transformation of Food into Energy When we eat carbohydrate containing foods, they arrive at our stomach and begin to break down. From the stomach, the partially broken down food travels to the small intestine where it completely breaks down into many compounds, one being glucose. From the small intestine the glucose is absorbed into the blood stream. A hormone called insulin which is secreted by our pancreas, accompanies the glucose from the blood to our liver and muscle cells, where it is stored in the form of glycogen. From this…
