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.
Deficiencies, excesses and imbalances in ones diet can produce negative impacts on health, which may lead to diseases such as cardiovascular disease, diabetes, obesity or osteoporosis, as well as psychological and behavioral problems. Fatigue, weight gain or loss, irritability, mood swings, delay of healing, or delayed healing from injuries or infections can also be signs of a nutritional imbalance.
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.
