 'Apple a Day' Advice Rooted in Science 
 
			
			ScienceDaily (May 3, 2011) �  Everyone has heard the old adage, "an apple a day keeps the doctor  away." We all know we should eat more fruit. But why apples? Do they  contain specific benefits?
 
 According to Dr. Bahram H. Arjmandi, PhD, RD, Margaret A. Sitton  Professor and Chair, Department of Nutrition, Food and Exercise Sciences  at The Florida State University, apples are truly a "miracle fruit"  that convey benefits beyond fiber content. Animal studies have shown  that apple pectin and polyphenols in apple improve lipid metabolism and  lower the production of pro-inflammatory molecules. Arjmandi's most  recent research is the first to evaluate the long-term cardioprotective  effects of daily consumption of apple in postmenopausal women.
 
 
 The results of this USDA-funded study will be presented at Experimental Biology 2011 on April 12 in Washington, DC.
 
 
 This study randomly assigned 160 women ages 45-65 to one of two  dietary intervention groups: one received dried apples daily (75g/day  for 1 year) and the other group ate dried prunes every day for a year.  Blood samples were taken at 3, 6 and 12-months. The results surprised  Dr. Arjmandi, who stated that "incredible changes in the apple-eating  women happened by 6 months- they experienced a 23% decrease in LDL  cholesterol," which is known as the "bad cholesterol." The daily apple  consumption also led to a lowering of lipid hydroperoxide levels and  C-reactive protein in those women.
 
 
 "I never expected apple consumption to reduce bad cholesterol to this  extent while increasing HDL cholesterol or good cholesterol by about  4%," Arjmandi said. Yet another advantage is that the extra 240 calories  per day consumed from the dried apple did not lead to weight gain in  the women; in fact, they lost on average 3.3 lbs. "Reducing body weight  is an added benefit to daily apple intake" he said. Part of the reason  for the weight loss could be the fruit's pectin, which is known to have a  satiety effect. The next step in confirming the results of this study  is a multi-investigator nationwide study.
 
 
 There is frequently some truth behind our common expressions, and in  the case of 'an apple a day,' Dr. Arjmandi has shown that nutrition  science backs up the expression. "Everyone can benefit from consuming  apples," he said.
