Every living thing, animals, plants, and microorganisms alike, requires a constant supply of nutrients to survive. A life without being periodically refreshed with a new supply of nutrient can’t be sustained. Although some simple organisms just absorb the nutrients they need from their environment into their body system, complex organisms like men have a more complex way of deriving their much-needed nutrients. Humans/some other organisms higher on the evolution pyramid derive their supply of nutrient from eating food, which is then broken down in a process called digestion to give nutrients as its end product. Men classified food into different groups based on the type of nutrient they contain and their major contributions to the body.
Foods are classified as proteins when they contain higher levels of amino acids than other constituents. The body uses proteins to build and repair worn-out tissues, examples include fish, beans or meat. Carbohydrates are the body’s main supply of energy, dietary significant carbs largely exist as sugars in food. Foods considered to be carbs include rice, yam, wheat, cassava, etc. Fats are used as an alternative source of energy when carbohydrates are in low supply in a person’s diet. It constitutes the largest portion of your body’s energy reserve, plus they keep us insulated from extreme weather and serve as a cushion for vital organs.
Vitamins and minerals mainly serve a maintenance role in the body plus assists in carrying out the majority of activities in the body. These include; immune response, conversion of food into energy, repair of cellular damage, transport of oxygen through the bloodstream, and other related activities. The liquid compound, water is also considered as a type of nutrient, due to its several roles in the body, plus the fact that it needs to be taken daily to maintain a healthy body. Roughages are also known as fibers are the newest addition to the nutrition world. Although it can’t be digested by the human body, it plays vital roles in the body which makes it worthy of being classified as parts of nutrients.
They largely improve your digestive health, that is, reducing the problems/complications that some times come with the processing of food items by the body. Fibers are an important food source for the symbiotic bacteria present in your gut. They similarly help to improve bowel movement and increase the bulk of stools for efficient excretion of waste. Roughages have yet been proven to assist in weight reduction and reduce the probability of suffering from heart-related diseases by a person. Fibers are classified into two types based on their solubility, there are soluble fiber and insoluble fiber. Soluble fiber which is present in wheat can absorb water, which makes them easily digestible by the microorganisms present in the gut.
Insoluble fiber, however, is resistant to water and passes through the whole length of the alimentary canal without being broken down. It contributes greatly to the accumulation/excretion of large bulk of the waste produced by the body. Roughages are highly important in our diet, especially for maintaining your dietary health. It is advised that 14g of fiber should be taken per a thousand calories consumed daily. That is, approximately 25g for females and 38g for males.
