An article published recently in the american Journal of Clinical Nutrition reveals an association between increased vegetable and fruit intake and a lower risk of dying during 13 years of follow-up.
the analysis included 38,221 participants in the Cohort of Swedish Men who were recruited between 1997 and 1998, and 33,485 women recruited from 1987 to 1990 to participate in the Swedish Mammography Cohort. Questionnaires completed upon enrollment provided data concerning diet over the previous year, alcohol intake, and other lifestyle factors.
From the beginning of 1998 through 2010, 6,803 men and 4,637 women died. In comparison with subjects who consumed the recommended five servings of fruit and vegetables per day, those who did not consume fruit or vegetables had a 53% greater risk of dying over follow-up.
