There are six main classes of nutrients that the body needs:
It is important to consume these six nutrients on a daily basis to build and maintain healthy bodily function. | NutritionNutrition is a science that studies the relationship between diet and health . There is a large spectrum ranging from malnutrition to optimal health, which included many common symptoms and diseases which can often be prevented or alleviated with better nutrition. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as scurv, obesity or osteoporosis, as well as psychological and behavioral problems. Moreover, excessive ingestion of elements that have no apparent role in health, (e.g. lead, mercury, PCBs, dioxins ), may incur toxic and potentially lethal effects, depending on the dose. The science of nutrition attempts to understand how and why specific dietary aspects influence health. Poor health can be caused by an imbalance of nutrients, either an excess or deficiency, which, in turn, affects bodily functions cumulatively. Moreover, because most nutrients are involved in cell-to-cell signaling (e.g. as building blocks or as part of a hormone or signaling cascades ), deficiency or excess of various nutrients affects hormonal function indirectly . Thus, because they largely regulate the expression of genes, hormones represent a link between nutrition and how our genes are expressed, i.e. our phenotype . The strength and nature of this link are continually under investigation, but recent observations have demonstrated a pivotal role for nutrition in hormonal activity and function and therefore in health.
