Can mechanistic research in nutrition contribute to a better understanding of relationships between diet and non-communicable diseases (NCD)?

Most of the evidence linking diet with complex diseases such as heart disease and cancer (non-communicable diseases (NCD)) is based on findings from epidemiological cohort studies which follow large populations of people to determine whether groups of people who have been diagnosed with or died from the disease, have diets that differ from those who are free from the disease. A limiting factor in these studies is their observational nature which limits the certainty about causal relationships between the exposure (diet) and the outcome (NCDs). Randomised controlled trials (RCTs), where a dietary factor is fed under carefully controlled circumstances, have a greater ability to prove the dietary factor is causing the disease and provide confidence for policymaking.

Excess body weight exacerbates the harmful effect of alcohol on cancer risk

Excess body weight and alcohol consumption are both modifiable risk factors for many adverse health outcomes, including cancer. Alcohol is classified as Group 1 carcinogen by the International Agency for Research on Cancer (IARC), and alcohol consumption is associated with a higher incidence of seven cancer types. Excess body weight is also associated with at least 13 cancer types. Although these factors have been known to be linked with cancer for many years, very few studies have investigated the joint association between alcohol consumption and excess body weight with cancer risk.
