For your healthy diet, it is better to live in West Africa than in the West. According to a study published in The Lancet Global Health people in Mali, Chad, Senegal, and Sierra Leone enjoy healthier diets than their counterparts in the United States, the United Kingdom, Japan or Canada. A research team of the University of Cambridge surveyed diets in 198 countries. The team looked at the intake of healthy foods such as fruit, vegetables, legumes, whole grains, and fish, as well as foods containing fiber and omega-3s as well as at the consumption of unhealthy foods such as sugary drinks, saturated fats, sodium, and processed meats.
