The word protein comes from a Greek word meaning of primary importance, which is an apt description of these macronutrients; they are also known colloquially as the workhorses of life. Most importantly, they provide the energy for the most obvious functions of our body, such as moving or thinking, but also for the background functions that most of the time we do not even notice1. A slightly more complex type of carbohydrate is the oligosaccharide (e.g., raffinose and stachyose), which contains three to 10 saccharide units; these compounds, which are found in beans and other legumes and cannot be digested well by humans, account for the gas-producing effects of these foods.

Pineapple Dietary fibre is thought to provide important protection against some gastrointestinal diseases and to reduce the risk of other chronic diseases as well. The truth of the matter is that although fiber is classified as a carbohydrate it has no calories and doesnt raise blood sugar levels. There is one other nutrient that we must have in large quantities: water. Lipids are found predominantly in butter, oils, meats, dairy products, nuts, and seeds, and in many processed foods. Some types of fibre can, however, be metabolised by gut bacteria, giving rise to compounds beneficial for our body, such as short-chain fatty acids. Soluble fibre, which dissolves or swells in water, slows down the transit time of food through the gut (an undesirable effect) but also helps lower blood cholesterol levels (a desirable effect).
