Higher sugar intake can lead to the development of breast cancer from high sugar diets.Increased sugar intake can cause existing cancer to grow faster. On the other hand higher sugar intake makes you gain weight, which leads to an increased risk of getting cancer.
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.
Lung metastases in breast cancer patients who consume a lot of sugar
Sugar in food is also one of the big causes why breast cancer spreads to the lungs causing lung metastases more often. The cause of that is the production of a fatty acid metabolite (called 12-HETE), which stimulates breast cancer cells to 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.
Dietary fiber binds sugar and sugar is complex carbs bind. Here it does not cause an insulin reaction. But when sugar is unbound in sugary drinks and low fiber starchy foods it can cause breast cancer . 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 the researchers compared this 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 showed a positive linkage to the development of breast cancer.
Scientists confirmed that sugar, sugary drinks and low fiber starchy foods can cause breast cancer. It does so in both animal models and in human clinical trials. 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.
