Raspberries might prove a future tool in the fight against cancer. New research reveals that extracts of the summer fruit kill stomach and colon cancer cells.
In a preliminary study, 90 per cent of these cells were destroyed when exposed to an extract of red Meeker raspberries, a popular variety in the U.S.
Antioxidants in the fruit were also shown to kill breast cancer cells.
US researchers say that while the antioxidants in the red fruit explain some of the effects, other as yet unidentified compounds seem to be at work as well.
Unfortunately, experts believe the anti-cancer effect is seen only when the extract is applied directly to the diseased cells, and not when the fruit is eaten.
The research team now hope to start further studies to pinpoint the other cancer-fighting compounds in the fruit.
Also, did you know that nose spray keeps your hunger pangs at bay?A nasal spray that masks the smell of food could help overweight people to lose pounds. US researchers have discovered that a type of drug used to lower blood pressure can also curb appetite and lead to weight loss.
The drug used, CP404, is a calcium channel blocker. Calcium produced by the body can narrow blood vessels and raise blood pressure; calcium-channel blockers work by helping the blood vessels relax and widen, lowering pressure.
However, calcium is also thought to play a role in the sense of smell. Results from the first human trial of the spray show it blocked the sense of smell compared with a simple saline spray, and had no side-effects.
As a result, participants were less interested in, and consumed less, food.
