Peaches are a great source of vitamin C and one medium peach (with skin) contains 1.36 grams of protein, 58 calories and 2.2 grams dietary fibre. Early research now suggests adding peaches to you diet can have protective benefits.
A Washington State University (WSU) food scientist published findings in the Journal of Nutritional Biochemistry outlining results from an animal study that found compounds in peaches can inhibit the growth of breast cancer cells and their ability to spread.
Researchers say the compounds could be a novel addition to therapies that reduce the risk of metastasis, the primary killer in breast and many other cancers. In the western hemisphere, breast cancer is the most common malignant disease for women. In the USA last year, the American Cancer Society estimated about 232,340 new cases of invasive breast cancer among women. The article says that the compounds could be given as peach polyphenol extract powder or be sourced from two to three fresh peaches a day.
Giuliana Noratto, WSU assistant professor of food science says that having enough fruits and vegetables in our diet can provide these compounds, and might have a similar preventive effects. She is now looking at other compounds such as wheat, barley, quinoa, apples and dairy products that could also have a role in preventing obesity-related diseases.
The WSU assistant professor is said to have been drawn to the research after doing work on the antioxidant activity of root plants in her native Peru where they have a huge tradition of medicinal plants. Noratto said. “We are great believers that you can cure yourself by having a good diet and a good supply of medicinal Plants”
How great would this be if the benefits could be replicated in human trials. To achieve this however, further in vitro and in vivo studies are needed to understand the molecular mechanisms involved.
