What is one effect of good nutrition on life expectancy?

Good nutrition plays a critical role in enhancing longer life expectancy by providing the body with essential nutrients that support overall health and well-being. A balanced diet rich in vitamins, minerals, antioxidants, and healthy fats contributes to the proper functioning of bodily systems, which helps reduce the risk of chronic diseases such as heart disease, diabetes, and obesity. These conditions can significantly impact lifespan, so by maintaining good nutritional habits, individuals can improve their health status and longevity.

Moreover, good nutrition supports a strong immune system and promotes healthy weight management, both of which are vital for prolonging life. It fosters better mental health as well, which can also contribute to a longer life span.

In contrast, the other options do not align with the impact of good nutrition on life expectancy. While nutrition can positively influence stress levels and overall self-esteem, it is predominantly associated with enhancing longevity rather than leading to negative feelings or chronic fatigue.
