Recent research indicates that increased consumption of fruits and vegetables by middle-aged people reduces their susceptibility to heart attacks in later years. The researchers speculate that this may be because fruits and vegetables are rich in folic acid. Low levels of folic acid are associated with high levels of homocysteine, an amino acid that contributes to blocked arteries. Which one of the following statements is most strongly supported by the information above?Choices:- An increased risk of heart attacks is correlated with low levels of homocysteine. A decreased risk of heart attack is correlated with increased levels of folic acid. An increased propensity for blocked arteries is correlated with decreased levels of homocysteine. A decreased propensity for blocked arteries is correlated with low levels of folic acid.

Studies have shown a correlation between diets high in fruits and vegetables and cardiovascular health. Nutrients in fruits and vegetables have been found to reduce risk markers for cardiovascular disease. A team of researchers studying the effects of drinking carrot juice on cardiovascular health concluded that drinking carrot juice without making other dietary changes is insufficient for reducing risk markers for cardiovascular disease. Which finding from the study, if true, would most directly support their conclusion?Participants in the study saw an improvement in their cardiovascular health after drinking a serving of carrot juice in addition to their regular diet.eliminateDrinking a serving of carrot juice in addition to their regular diet increased the antioxidant status of participants in the study.eliminateDrinking a serving of carrot juice in addition to their regular diet did not improve cardiovascular disease risk markers for participants in the study.eliminateParticipants in the study were within normal ranges for interleukin-1α, which, when elevated, is a risk marker for cardiovascular disease.
