The objective of the study was to evaluate the association of carbohydrates and dietary fibre with breast cancer risk. A total of 74,942 women aged 40-70 were involved in the study which lasted over 7 years.
The study found:
- Women who ate the most carbohydrate had a 22% increased rate of breast cancer compared to the women who ate the least carbohydrate.
- Women who ate the most fibre had a 9% increased rate of breast cancer compared to the women who ate the least fibre.
This study found that increased dietary carbohydrate and fibre leads to higher rates of breast cancer.
