The food which we use daily include rice, wheat, dal, vegetables, fruits, milk, egg, fish, meat, sugar, butter, oils, etc.


The different foods are made up of a number of chemical components called nutrients. These are classified according to their chemical composition.


Every nutrients has different functions, but the various nutrients must act in unison for effective action.


The nutrients found in foods are- carbohydrates, Proteins, fats, Minerals, vitamins and water.


Fiber is also an essential component of our diet. The functions of nutrients are given below.

CARBOHYDRATES-


1. Starch found in cereals and sugar in sugarcane and fruits are example of carbohydrates in foods. The chief function of carbohydrates is to provide energy needed by our body. Those not used immediately for this purpose are stored as glycogen or converted to fat and stored, to be mobilized for energy supply when needed.

FATS

1. Oils found in seeds, butter from milk, and lard from meat, are example of fats found in foods fats are concentrated sources of energy, carries of fat soluble vitamins and a source of essential fatty acids. If excess fats are taken in the diet, these are stored as fat reserves in the body. energy taken in excess of body needs, is stored as fat in the body.

PROTEINS


1. Casein from milk, albumin in egg, globulins in legumes and gluten in wheat, are examples of proteins occurring in foods. The main function of protein is the building of new tissues and maintaining and repair of those already built. Synthesis of regulatory and protective substance such as enzymes, hormones and antibodies is also a function of food protein. About 10 per cent of the total energy is supplied by protein in the diet.

 Understanding Brain Tumors: Types, Symptoms, and Treatments Introduction A brain tumor is an abnormal growth of cells in the brain or surrounding tissues. These tumors can be either benign (non-cancerous) or malignant (cancerous), and they vary widely in their behavior, treatment options, and prognosis. This article provides an overview of brain tumors, including their types, symptoms, diagnosis, and treatments. Types of Brain Tumors Brain tumors are classified based on the type of cell they originate from and their location within the brain. The main categories include: Primary Brain Tumors : These originate within the brain itself or its immediate surroundings. Gliomas: The most common type, originating from glial cells. Subtypes include astrocytomas, oligodendrogliomas, and glioblastomas. Meningiomas: Arising from the meninges, the membranes surrounding the brain and spinal cord. Pituitary Adenomas: Tumors developing in the pituitary gland, affecting hormone production. Medullob

Cystic Fibrosis- causes and symptoms

Image
Introduction Cystic fibrosis (CF) is a hereditary disorder that primarily affects the lungs and digestive system. It is characterized by the production of abnormally thick and sticky mucus that can clog the airways and obstruct the pancreas. CF is a progressive disease, leading to severe respiratory and digestive problems, and it often results in a shortened lifespan. Causes Cystic fibrosis is caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. This gene is responsible for the production of a protein that regulates the movement of salt and water in and out of cells. Mutations in the CFTR gene result in the production of a defective protein, leading to the accumulation of thick mucus in various organs. Symptoms The symptoms of cystic fibrosis can vary widely but commonly include: Respiratory symptoms: Persistent coughing, frequent lung infections (including pneumonia and bronchitis), wheezing, and shortness of breath. Digestive symptoms: Difficu
