This "1" thing found in restaurants may harm your breasts!

We all love to take the time to relax from cooking at home and enjoy a meal out.  BUT... what if you were being exposed to something that could potentially harm you, namely your breasts? 
​

A recent study showed that reheating cooking oil could cause you some serious harm. 

Deep-frying is a popular form of food preparation used globally and throughout in the United States. Each time dietary oils are heated to deep-frying temperatures, they undergo chemical alterations.  Reports of associations between thermally abused frying oil and deleterious health outcomes currently exist, yet there is little information concerning the effects of thermally abused frying oil consumption and the progression of breast cancer. 

Scientists fed lab mice a low-fat diet for a week. Then, they gave some of the mice unheated fresh soybean oil for 16 weeks while the rest ingested thermally abused oil instead. 
​
To simulate breast cancer, they injected 4T1 breast cancer cells into a tibia of each mouse. These breast cancer cells are very aggressive and have a high rate of metastasis to multiple distant sites. 

At 20 days after the injection of the tumor cells, there was a notable difference in the rate of metastatic growth between the two groups of mice. In the mice who had eaten thermally abused oil, the metastatic growth of the tibia tumors was four times greater than that of the tumors in the mice who consumed the fresh oil.

There were also more lung metastases in the former group. Lead researcher William G. Helferich, a professor of food science and human nutrition, noted that there were twice as many lung tumors, which were also more aggressive and invasive than those in the fresh-oil group.

REASONS TO BE CONCERNED: 

• Restaurants and other food outlets often reuse soybean oil multiple times before replacing it with fresh oil in the frying vats.
• These factors are what led the researchers to investigate whether thermally abused oil could have any effect on breast cancer growth.
• Although the results are preliminary, they add to a knowledge base that will grow deeper as research in this area continues.
