Eating healthy is the key to improving the overall health. People who consume more whole grains, vegetables, fruits, nuts, fish and limit the intake of red and processed meats and sugary beverages may reduce their risk of early mortality. The study found that improving diet quality over 12 years is associated with lower total and cardiovascular mortality. The findings emphasize the importance of maintaining healthy eating patterns in the long-term. People who improve their diet quality over time may significantly reduce their risk of premature death.
