A study of 4,600 adolescents (11-18 years old) found:

Thirty-three percent ate two or fewer family meals with all or most of their family the previous week.

Twenty-six percent ate seven or more meals with their family.

Researchers found that adolescents who ate more meals with their family suffered significantly lower rates of cigarette, alcohol, and drug abuse, enjoyed higher grade point averages, and struggled less with depression and suicide.
