From the Guidelines

A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats is crucial for improving life satisfaction by affecting both physical health and mental wellbeing. To enhance life satisfaction through diet, it is essential to focus on nutrient-dense foods. The Mediterranean diet pattern, which is high in fiber, unsaturated fatty acids, and polyphenols, and lower in saturated fats, sodium content, and processed carbohydrates, has been associated with a decreased risk of metabolic syndrome and cardiovascular disease 1. Although a recent study found that increasing fruit and vegetable consumption did not significantly improve happiness in the short term 1, the overall evidence suggests that a healthy diet has numerous benefits for physical and mental health.

Some key recommendations for improving life satisfaction through diet include:

  • Aiming for 5-7 servings of fruits and vegetables daily
  • Choosing whole grains over refined carbohydrates
  • Including omega-3 fatty acids from sources like fish or walnuts
  • Limiting processed foods high in sugar and unhealthy fats
  • Staying hydrated by drinking 8-10 glasses of water daily
  • Gradually replacing processed foods with whole foods
  • Meal planning to ensure nutritional variety
  • Being mindful of emotional eating patterns that may undermine both diet quality and life satisfaction

It is also important to note that lifestyle therapy, including a healthy diet, can improve the quality and quantity of life, even in persons with multiple risk factors and comorbidities 1. Additionally, food insecurity and nutrition insecurity are significant challenges in the United States, and addressing these issues is crucial for improving health outcomes 1. By prioritizing a balanced and nutritious diet, individuals can take a significant step towards improving their life satisfaction and overall wellbeing.
