Women with osteopenia may be able to reduce their bone breakdown by consuming a daily amount of 9 or more servings of vegetables and fruits. But not just any vegetables and fruits, as reported by a recent New Zealand study that highlighted which bone superfoods can make the biggest difference.
Here’s what these researchers found when they tested the effects of known bone super foods on women’s ability to build bone.
How the study tested bone superfoods
The study group of 142 postmenopausal women (mean age 60 years) was divided into three groups: a control group, which had no change to their existing diets, and two intervention groups of 50 women each, both of which were instructed to increase their consumption of vegetables and fruits to 9 or more servings (1/2 cup cooked or 1 cup raw) each day and to add some aromatic culinary herbs to each meal. Participants in one group chose from foods that emphasized specific vegetables/herbs/fruit known to reduce bone breakdown (aka bone superfoods). The other group was left to choose their 9 servings per day, but could not consume any of the bone superfoods.
Most of the women in the intervention groups (52%) had osteopenia; the rest mainly had normal bone density, although a few had osteoporosis.
No surprise: More plant foods lead to better bone health
The study found that:
- Both intervention groups consuming the 9 servings of vegetables experienced significantly reduced loss of calcium and a rise in urinary pH compared to the control group.
- Women in the group that ate the bone superfoods were the only ones to reach the daily internationally recommended level of 4700 mg of the key bone nutrient, potassium.
- A significant reduction in bone breakdown was seen in women with osteopenia whose 9 or more servings of vegetables and fruits included the bone superfoods. This is a very positive marker, as excessive bone breakdown leads to further osteopenia and even osteoporosis.
