In most countries, males have ~2-3 times higher incidence of primary liver cancer than females. Sex hormones have been hypothesized to contribute to these differences, but the evidence remains unclear. Using data from the UK Biobank, which included ~200,000 males and ~180,000 postmenopausal females who provided blood samples at recruitment, we estimated hazard ratios (HR) and 95% confidence intervals (CI) for a doubling in hormone concentration from multivariable adjusted Cox regression for circulating total testosterone, sex-hormone binding globulin (SHBG), and free testosterone concentrations and risk of primary liver cancer.

Background And Aims: Excess energy intake can lead to metabolic dysfunction-associated steatotic liver disease (MASLD), but the relationship between dietary carbohydrate intake and liver fat content remains unclear. This study aimed to examine the associations between types and sources of dietary carbohydrates and liver fat content.

Methods: UK Biobank participants with no pre-existing diabetes, liver disease or cardiovascular disease reported dietary intake of types and sources of carbohydrates (total carbohydrates, free sugars, non-free sugars, starch from whole grains, starch from refined grains, and fibre) on at least two 24-h dietary assessments.

Article Synopsis
  • The study analyzed dietary protein intake, especially from dairy sources, among 114,217 UK Biobank participants to assess links with colorectal, breast, and prostate cancers over a median follow-up of 9.4 years.
  • Results showed lower risks of colorectal cancer with higher intakes of total dairy protein, milk protein, and dietary calcium, but higher risks of prostate cancer with milk protein and dietary calcium.
  • The researchers concluded that more studies are needed to explore how dairy products impact cancer risk and to clarify the roles of dietary protein and calcium in these associations.

Introduction: Prior studies have demonstrated that an intake of foods rich in dietary fiber is associated with a favorable impact on health status and body weight. However, the association between fiber intake and weight loss has not been well-studied in employer settings. This research aimed to assess the relationship between dietary fiber and weight loss among individuals participating in the Full Plate Living (FPL) program.

Unlabelled: Whole grain and fiber intakes may decrease the risk of colorectal cancer. The interplay between host genetic factors, colonization of specific bacteria, production of short-chain fatty acids (SCFA), and intake of whole grains and fiber could alter the protective role of carbohydrates against colorectal cancer. Here, we assessed intakes of types and sources of carbohydrates in 114,217 UK Biobank participants with detailed dietary data (2-5 24-hour dietary assessments), and a host polygenic score (PGS) was applied to categorize participants as high or low for intraluminal microbial SCFA production, namely, butyrate and propionate.

Background: Recent studies have reported that the associations between dietary carbohydrates and cardiovascular disease (CVD) may depend on the quality, rather than the quantity, of carbohydrates consumed. This study aimed to assess the associations between types and sources of dietary carbohydrates and CVD incidence. A secondary aim was to examine the associations of carbohydrate intakes with triglycerides within lipoprotein subclasses.

Article Synopsis
  • The study investigates the relationship between food intake and circulating insulin-like growth factor-I (IGF-I) concentrations, which are linked to cancer risk and bone fractures.
  • Researchers analyzed data from 438,453 participants in the UK Biobank who reported their food consumption and had their serum IGF-I levels measured.
  • Results indicated that eating oily and non-oily fish at least twice a week was associated with higher IGF-I levels, while poultry consumption also showed a weaker positive association; further research is needed to explore these findings.

Background: Following a vegetarian diet has become increasingly popular and some evidence suggests that being vegetarian may be associated with a lower risk of cancer overall. However, for specific cancer sites, the evidence is limited. Our aim was to assess the associations of vegetarian and non-vegetarian diets with risks of all cancer, colorectal cancer, postmenopausal breast cancer, and prostate cancer and to explore the role of potential mediators between these associations.
