NHS Choices examines the science behind the newspaper headlines.

Conclusion

This study has suggested a link between consumption of certain fats in the diet and risk of death from cancer in men with the disease over twenty years of follow up.

There are a number of limitations to this study:

The number of men included was relatively small, and groups being compared would be smaller once the men began to be divided by cancer stage and fatty acid intake.

The study carried out many statistical tests. This means we might expect to see some significant results arising just by chance. The researchers noted that some of their results would not remain statistically significant if they took the number of tests into account.

The men had to report their food consumption in the year prior to diagnosis and it may have been difficult to accurately recall what they had eaten. When the researchers compared a sample of men?s food questionnaire answers with a food diary, there was not very strong agreement. The men?s diets could also have changed over time, which could influence results.

Although the researchers took into account a number of factors that could influence the results, these or other factors could still be contributing to the differences seen.

The results will need confirmation in other studies
