Vitamin C in white vegetables like potato acts as an antioxidant to cut down cellular stress in the stomach and it also fights a bacterium responsible for causing gastric cancer.
Scientists have discovered that eating potatoes and cabbage can help reduce the risk of developing stomach cancer.
It found that people who eat a large amount of white vegetables, such as onions and cauliflower, were a third less likely to develop it than those who did not eat them.
But the risk was increased through beers, spirits, salt and preserved food.
The study was conducted by scientists at Zhejiang University in China.
It used 76 existing studies into diet and stomach cancer which have involved 6.3m people being surveyed and 33,000 deaths from the disease.
It found that for every 100g of fruit someone eats daily the risk of developing stomach cancer is reduced by fiver per cent, the risk was reduced to eight per cent for every 50mg of vitamin C - the equivalent of two potatoes.
Whereas salt increased the risk by 12 per cent.

Cabbage, kale and celery were also found to be preventives against the disease.
All of the vegetables are thought to contain vitamin C, commonly found in potatoes, which acts as an antioxidant against cellular stress in the stomach. Eating around 50g of the vitamin every day brought the risk of developing the disease down by eight per cent.
Scientists estimated for every 100g of fruit eaten daily the risk of cancer decreased by an average of five per cent.
Vitamin C is thought to be the key nutrient, which acts as an antioxidant to cut down cellular stress in the stomach as well as fighting a bacterium responsible for causing gastric cancer. The scientists analysed 76 best studies on diet and stomach cancer, which involved more than 6.3 million people and almost 33,000 deaths from the disease, The Times reported.
"Both fruit and white vegetables are rich sources of vitamin C, which showed significant protective effect against gastric cancer by our analysis."
