Current levels of potato consumption in relation to mortality in Chinese people remains unknown. The aim of this study was to investigate the intakes of total potatoes, fried potatoes, non-fried potatoes, and sweet potatoes as dietary carbohydrate sources in relation to all-cause mortality in the China Health and Nutrition Survey (CHNS). ⋯ In the CHNS, current low and moderate, but not high levels of total potato and fried/non-fried potato consumption as well as sweet potato consumption were inversely associated with all-cause mortality among Chinese people.

A diet rich in fish and ω-3 polyunsaturated fatty acids (PUFAs) has been thought to reduce the risk for cardiovascular disease (CVD). The beneficial effects of fish oil and ω-3 PUFA on CVD can be mediated by epigenetic status of the genes associated with lipid metabolism and inflammation. The aim of this study was to investigate whether dietary fish and fatty acid (FA) intakes are associated with leukocyte ATP-binding cassette transporter A1 (ABCA1) DNA methylation levels in a Japanese population. ⋯ Higher dietary fish and ω-3 PUFA intake were associated with lower ABCA1 DNA levels in a Japanese population. The present results may bring potential insights on biological mechanisms underlying the protective effects of dietary fish and ω-3 PUFA intakes on CVD.

Liver fibrosis is a common pathologic process related to chronic liver disease. However, there are currently no effective methods to reverse liver fibrosis. Chronic liver disease is typically associated with a major imbalance in the intestinal flora, and targeting the regulation of the intestinal flora structure may facilitate the prevention and treatment of chronic liver disease. Therefore, in this study, we explored the effects of dietary fiber on the prevention of liver fibrosis in mice. ⋯ Our findings revealed the complex relationships between dietary fiber, intestinal flora, and immunity, and suggested that dietary therapy could alleviate liver fibrosis.
