Exercise 6

As we will see in the next chapter, atherosclerosis is a condition in which fatty deposits accumulate in arteries and can block blood flow. Atherosclerosis in coronary arteries can deprive cardiac muscle cells of adequate oxygen and nutrients, causing a heart attack. Cholesterol oxidation is a factor causing atherosclerosis, so Israeli researchers1 tested the hypothesis that a diet high in antioxidants will slow this process. They treated both cultures of arterial cells and mice with atherosclerosis to a mixture of pomegranate juice and dates for three weeks. They found that this cocktail reduced cholesterol oxidation by 33% and cholesterol accumulation in arterial cells by 28%. The researchers conclude that people, especially those at high risk of atherosclerosis, would benefit from drinking half a glass of pomegranate-date cocktail a day.
Based on the experimental design, is the conclusion and the recommendation that people would benefit from drinking a daily dose of pomegranate and date juice valid
