Healthier Foods and Special Diets
What Our Bodies need for life Carbohydrates Protein Calcium Vitamin A Vitamin B (Folic Acid) Iron
Carbohydrates Come from : Carbohydrates are found in almost all living things and play a critical role in the proper functioning of the immune system, fertilization, pathogenesis, blood clotting, and human development.
Protein Comes From : Protein is a macro nutrient composed of amino acids that is necessary for the proper growth and function of the human body. While the body can manufacture several amino acids required for protein production, a set of essential amino acids needs to be obtained from animal and/or vegetable protein sources.
Calcium Comes From: Calcium is needed for good teeth and strong bones and for the proper function of nerves, muscles, kidneys, and the heart. Not having enough calcium in the diet is one of many factors associated with an increased risk of osteoporosis, a disease that speeds up the process of the natural loss of calcium in the bones. This causes the bones to become weak and fragile, leading to loss of height, curved spines, and bone fractures, especially in women. Calcium is especially important in Children as it helps them to develop strong teeth and bones as they grow.
Vitamin A Comes From: Vitamin A is an essential vitamin required for vision, gene transcription, boosting immune function, and great skin health. A deficiency in vitamin A can lead to blindness and increased viral infection, however deficiency is only considered a problem in developing countries where it is a leading cause of blindness in children
Vitamin B (Folic Acid) Comes from : Vitamin B (folic acid) is required for numerous body functions including DNA synthesis and repair, cell division, and cell growth. A deficiency of Vitamin B can lead to anaemia in adults, and slower development in children. For pregnant women, folic acid is especially important for proper foetal development.
Iron Comes from : Iron is an essential mineral used to transport oxygen to all parts of the body. A slight deficiency in iron causes anaemia (fatigue/weakness), and a chronic deficiency can lead to organ failure.
