Nutrition experts have studied plant-based diets over the course of a decade and have found a surprising impact on long-term happiness. Higher-quality plant foods, such as whole grains, fruits, vegetables, legumes, and nuts, have been linked with steadier moods and brighter lives. On the other hand, diets high in refined plant foods have been associated with a higher risk of developing depression.

The key takeaway is that the quality of plant foods, rather than simply the label of being plant-based, plays a significant role in mental health. Consistently consuming whole, minimally processed plants while limiting refined ones can lead to better emotional well-being over time. Incorporating more whole plants, reducing refined ones, and ensuring a balanced intake of essential nutrients like protein, B12, and omega-3s can contribute to long-term happiness and overall well-being.
