Drinking just two glasses of orange juice a day could increase your risk of getting the deadliest form of skin cancer.
A 26-year study found those who consume more than one serving of citrus fruit a day were a third more likely to develop melanoma.
One serving was defined as the equivalent of half of a grapefruit, one orange, or a six-ounce glass of grapefruit or orange juice.
The researchers sent regular questionnaires to assess 100,000 participants' lifestyle factors, medical history and diet.
Their study, published in the Journal of Clinical Oncology, found that melanoma risk was 36 per cent higher in those who consumed fruit or juice at least 1.6 times a day. Eating grapefruits appeared to have the strongest link to the disease, following by drinking orange juice.
