Eat dark leafy greens and prevent gall stones

12 percent of the population has gallstones

In a US study that followed more than 13,000 adults over ten years, women with higher blood levels of vitamin C had a lower chance of developing gall bladder disease. This was not the case for men. 

Foods high in vitamin C include capsicum, cabbage, Brussels sprouts, cauliflower, broccoli, green leafy vegetables, tomatoes, citrus fruits, pawpaw, kiwi fruit, strawberries and pineapple. You could try vitamin C supplements, but studies are inconsistent and taking vitamin C supplements can increase the risk of kidney stones.
