In June 2019 researchers from the USA published the results of their study to assess the association between nut consumption and risk of hepatocellular carcinoma. A total of 88,783 women and 51,492 men were included in the study and followed up for an average period of 28 years. Information on nut consumption was collected every 4 years via food frequency questionnaires. During the follow-up period 162 diagnoses of hepatocellular carcinoma were diagnosed. Results showed that nut consumption was not significantly associated with the risk of hepatocellular carcinoma. However, there was a suggestion that a higher tree nut consumption may reduce hepatocellular carcimona risk.
