How does diet impact overall well-being?

Diet significantly impacts overall well-being, especially mental health and happiness. Increasing daily fruit and vegetable intake can lead to higher life satisfaction and improved mood. This effect peaks at around eight servings per day, equivalent to the happiness boost seen when someone gains full employment. This positive cycle of healthy eating and improved mood can sustain the habit of consuming nutritious foods 1 2 3 4.

Whole foods contribute to superior mental clarity and consistent energy levels compared to processed foods, which can cause energy slumps. This is due to the balanced blood sugar levels and absence of chemical additives in whole foods 5. Additionally, dietary patterns rich in fruits, vegetables, whole grains, nuts, seeds, and legumes are linked to lower rates of chronic diseases and long-term health benefits, including mental health improvements 2 6.

Moreover, diet changes can significantly reduce symptoms of depression and anxiety, especially in young adults. Healthy eating habits established during adolescence and young adulthood can lower depression risks and improve mood long-term 6 7 8.
