The women in the study group also lost an average of 3.3 pounds even though the apples added another 240 calories to the usual daily diet. Dr. Bahram Arjmandi who led the study, suggested that weight loss may be due to the pectin in apples which satisfies hunger. Early animal studies had already suggested that apple and its components, e.g. apple pectin and polyphenols, improve lipid metabolism and lower the production of proinflammatory molecules. The authors believed that this study was the first to look at the cardioprotective effects of daily consumption of apple for one year in postmenopausal women.
Of course, more studies will need to be done to reconfirm these results and look at the cellular interactions but we already know that apples are a good source of fiber, so why not have "an apple a day!"
