Fruits, Veggies May Bolster Bones

Study's Findings May Be 1 More Reason to Put Produce on Your Plate

June 14, 2006 -- Eating lots of fruits and vegetables might strengthen bones, according to a study in The American Journal of Clinical Nutrition.

But most people fall short of the recommended five or more daily servings of fruits and vegetables, the study also shows.

The study comes from research scientist Celia Prynne, PhD, and colleagues at MRC Human Nutrition Research, located in Cambridge, England. Data included 237 adolescents, 120 young women, and 143 senior citizens.

Participants got bone densitybone density scans and kept food diaries for seven days. Prynne's team found that adolescents and older women with higher intake of fruits and vegetables had denser bones than those who skimped on fruits and vegetables.

How Many Servings?

The researchers took a close look at participants' food diaries. They focused on consumption of fruits and vegetables. They added nuts to the fruit category and didn't count potatoes with the vegetables.

Prynne's team notes that the World Health Organization recommended in 1990 that people eat at least five daily servings of fruits and vegetables. But in Prynne's study, only a quarter of adolescents, 38% of young women, and 50% of the older adults met that goal.

Women in the oldest age group were most likely to meet the five-a-day serving goal.

"A recommendation to increase fruit and vegetable intakes, particularly in young people, would be expedient, because indications are that intakes in this age group are generally very low," the researchers write.

What's a Serving?

"One serving of fruits and vegetables should fit within the palm of your hand -- it's a lot smaller than most people think," states the U.S. government's "Eat 5 to 9 a Day for Better Health" web site.

That web site offers these examples of a serving of fruit or vegetable:

  • A small glass of 100% fruit or vegetable juice (6 ounces or three-quarters of a cup)
  • A medium-sized piece of fruit, such as an orange, small banana, or medium-sized apple
  • A half cup of cooked vegetables
  • A half cup of cut fruit or vegetables
  • A quarter cup of dried fruit

Let's say you have a glass of 100% orange juice and a banana as part of your breakfast, a salad with your lunch, an apple as a snack, and a side of vegetables with dinner. Congratulations! You've hit the five-a-day goal.
