Long-term nutritional deficiencies can lead to severe health consequences. For instance, a lack of essential vitamins and minerals may result in conditions such as osteoporosis from calcium deficiency or anemia due to insufficient iron. Chronic deficiencies can impair immune function, increasing susceptibility to illness, and may lead to fatigue and cognitive decline. Furthermore, ongoing poor nutrition can contribute to metabolic disorders and increase the risk of chronic diseases such as diabetes and heart disease. Addressing these deficiencies early is vital for maintaining overall health.
