New research has shed light onto the development of breast cancer from high sugar diets.
Animal experiments re. breast cancer from high sugar diets
High sugar content is one of the hallmarks of our Westernized diet. In order to test whether sugar or starch in our diet could contribute to breast cancer development scientists from the MD Anderson Centre, University of Texas conducted a series of mouse experiments. They fed four different types of diets to mice for 6 months. The group fed a starch rich diet developed breast cancer in 30% of cases within six months. A sucrose enriched diet (sugar diet) caused breast cancer in 58% after six months. So, there is no question that poor diets will lead to the development of breast cancer from high sugar diets. Sugar in food is also involved in causing breast cancer to spread to the lungs causing lung metastases more often. The cause of that is the production of a fatty acid metabolite (called 12-HETE), which makes breast cancer cells metastasize to the lungs.
It has been known for some time that refined sugar is causing cancer cells to thrive while normal cells are weakened.
But when sugar is bound by dietary fiber or is a part of complex carbs, it is metabolized slower and does not cause an insulin reaction. When we eat too much omega-6 fatty acids and not enough omega-3 fatty acids, this will also tip the balance in terms of cancer development.
Human evidence re. breast cancer from high sugar diets
An Iranian research group analyzed the food habits of 306 newly diagnosed women with breast cancer, aged 25 to 65 years. They all filled in dietary questionnaires and were compared to controls without breast cancer. The group with the highest consumption of whole-wheat bread and boiled potatoes were having lower breast cancer rates. High intake of legumes was significantly protecting against the development of breast cancer. In contrast the consumption of white bread and biscuits were positively linked to the development of breast cancer.
In both animal models and in humans it has been confirmed that sugar, sugary drinks and low fiber starchy foods can cause breast cancer. Cancer prevention seems to be a matter of fiber intake, intake of legumes, salads, vegetables and fruit. These latter produce items contain fiber and natural anti-cancer substances like lycopenes. The more you can free your food intake from sugar and empty starchy foods the better.
