Lack of nutrition knowledge can significantly impact health outcomes by leading to poor dietary choices and imbalances. Individuals might not understand the importance of macronutrients, leading to diets low in essential vitamins and minerals. This can result in various health issues, such as obesity, heart disease, and diabetes. Moreover, misinformation can perpetuate unhealthy eating habits and fad diets. Increasing nutrition knowledge empowers individuals to make informed choices, fostering better eating habits that promote overall health and well-being.
