Eggs are quite controversial being seen as both good and bad. Although packed with nutrients and anti-inflammatory properties, they are also high in cholesterol and choline.
In a Harvard Study it was found that people with a high choline intake had a 70% increased risk of fatal prostate cancer.
In our research we found eggs to be highly correlated in particular to stomach and lung cancers, with an average correlation of 0.63.
While studies such as McCullough et al (2005) state that some components in dairy products such as calcium may reduce the potential risk of postmenopausal breast cancer, evidence from studies such as conducted Tseng et al (2005) and Chan et al suggest that milk may contribute as a factor in the development of cancer.
In our findings, milk had the highest correlations with the most types of cancer we investigated. Achieving a strong coefficient of 0.78 with Prostate, Colorectal, Lung and Breast Cancers. This might suggest that a high milk consumption is related to cancer development.
In our study we looked at a mixture of classifications of meat, finding correlations with both regular and Bovine Meats. In 2015, the WHO stated that red meat has carcinogenic properties which means a high consumption of it could lead to increased risk in types of cancer such bowel cancer.
Our findings showed meat consumption to be related to prostate, colorectal, lung and breast cancers.
Soy has been a food associated with turning on genes which lead to cancer growth according to studies such as that done by Researchers at Memorial Sloan Kettering. We found a mild association between soybeans with stomach and liver cancer with a combined correlation coefficient of 0.64. This suggests that more evidence will need to be provided before the role of soybeans in the development of cancer can be determined.
Large meta-analysis studies show there is little association between coffee consumption and the occurrence of cancers.
In our study, we found coffee to be associated with prostate, colorectal and breast cancer with a concordance rate of 0.77. This may suggest that coffee consumption may be associated with other cancer causing habits.
Many studies have found evidence towards the association between animal fats and cancer, such as by Kestleloot et al (1991) and Carroll et al (1968). Our findings support this, finding strong associations of cancers Prostate, Colorectum, Lung and Breast with high consumption of animal fats.
According to the book, The China Study by T. Colin Campbell and his son Thomas M. Campbell II (2005) they argue that consumption of dairy products, including cheese can increase the risk in the development of cancer. We found a correlation of 0.8, which is a particularly high association, with Prostate, Colorectal, Lung and Breast cancers.
According to a study conducted by Cancer Research UK, they estimated that one in 20 British breast cancer cases could be caused by drinking. This is around 2,000 cases in total. Another figure from the study states that drinking a glass of wine a day increases a woman's chances of breast cancer by 6%. We found associations between high wine consumption with Prostate, Colerectal, Lung and Breast cancers.
In general alcohol consumption has been strongly associated with many types of caner. The multitude of studies include evidence for the impact of alcohol consumption with polymorphisms in alcohol-metabolizing enzymes and identified specific cancers such as Colorectal cancer and beer drinking in a study by Enstrom (1997). Wealso found a link between Colerectal cancer and beer consumption which supports these previous studies.
