Nutrition

Nutrition is a science that studies the relationship between diet and health. Dieticians are health professionals who specialize in this area of study, and are trained to provide safe, evidence-based dietary advice and interventions.

Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as cardiovascular disease, diabetes, scurvy, 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.

Many common diseases and their symptoms can often be prevented or alleviated with better nutrition. The science of Nutrition attempts to understand how and why specific dietary aspects influence health.

In general, eating a variety of fresh, whole (unprocessed) plant foods has proven hormonally and metabolically favourable compared to eating a monotonous diet based on processed foods. In particular, consumption of whole plant foods slows digestion and provides higher amounts and a more favourable balance of essential and vital nutrients per unit of energy; resulting in better management of cell growth, maintenance, and mitosis (cell division) as well as regulation of blood glucose and appetite. A generally more regular eating pattern (e.g. eating medium-sized meals every 2 to 3 hours) has also proven more hormonally and metabolically favourable than infrequent, haphazard food intake.
