Natural Health News – A diet rich in tomatoes may help protect postmenopausal women at risk for breast cancer.
risk of breast cancer in postmenopausal women rises rises as their body mass index. However, the study found that eating a diet rich in tomatoes had a positive effect on the level of hormones that play a role in regulating the metabolism of fat and sugar.
The longitudinal study “cross-over” examined the effects of both diets rich soy tomato and a group of 70 postmenopausal women. For 10 weeks, the subjects ate tomato products containing at least 25 milligrams of lycopene daily.
Over a period of 10 weeks apart, participants consumed at least 40 grams of soy protein a day. Before the start of each test period, women were instructed to refrain from eating both tomato products and soya for two weeks.
Better than soy?
When followed diet rich tomato, participants levels of adiponectin – a hormone involved in the regulation of sugar levels in the blood and fat – up 9%. The effect was slightly stronger in women who had a rate lower body mass.
“The results demonstrate the importance of prevention of obesity,” Llanos said. “Consuming a diet rich in tomatoes had a greater impact on hormone levels in women who maintained a healthy weight.”
The soybean diet was associated with a reduction in adiponectin levels of women.
Researchers have much theori s ed that a diet containing large amounts of soy could be part of the reason that Asian women have lower rates of breast cancer than women in the West. But considering these results, the researchers suggest that any beneficial effect could be limited to certain ethnic groups.
“The benefits of eating a lot of tomato products and tomato, even for a short period of time, were clearly evident in our findings,” he said lead author, Adana Llanos, PhD, MPH who is an assistant professor of epidemiology at Rutgers University.
“Based on these data, we believe that regular consumption of at least the recommended daily servings of fruits and vegetables promote the prevention of breast cancer in a population at risk,” he added.
The study results were published before its publication in the Journal of Clinical Endocrinology & Metabolism .
