Do Onions and Garlic Cut the Risk of Breast Cancer?

Epidemiologists find that Puerto Rican women who eat lots of onions and garlic have a lower chance of breast cancer.

Scientists suggest that the Puerto Rican culinary tradition of incorporating sofrito into many dishes might help explain a lower rate of breast cancer on the island (Nutrition and Cancer, Aug. 12, 2019). Puerto Rican cooks make this popular condiment with onions and garlic, two kinds of peppers, cilantro and a related herb, recao. 

The Importance of Onions and Garlic:

Puerto Rican women who ate lots of garlic and onions were 67 percent less likely to get breast cancer. Although sofrito is an important source of allium vegetables, total intake was important, not only the use of sofrito. Epidemiologists reached their conclusion by comparing diets of Puerto Rican women with and without breast cancer.

Why Might These Vegetables Help Against Breast Cancer?

The researchers point out that onions and garlic are rich in flavonols and sulfur-containing compounds that have anti-cancer activity. Other studies have found that certain sulfur compounds arrest cancer cell growth (International Journal of Molecular Sciences, July 28, 2017). Scientists around the world are studying allium vegetables for cancer prevention (Phytotherapy Research, Aug. 29, 2019).

Dr. Low Dog and others recommend onion and garlic every day. Forget the numerous pluses, but it certainly should not hurt. Easy, why not?

Good for you, and delicious!I always heard that it’s good, inexpensive insurance against different cancers.

No big money in onions and garlic. Big pharma cannot charge you thousands of dollars a month for onions and garlic. If every one knew about onions and garlic, the big pharma executives would have to sacrifice their lavish life styles.

I have experienced the awful side effects of big pharma’s expensive poisons. In addition, I am sick of the outrageous prices charged for medication. I have found excellent natural products that do not cost thousands a month. Turmeric, cinnamon, garlic, onions, curry, ginger root, beets, blueberries, and many other natural substances.

Promising information, since onions and garlic are inexpensive and often a staple in the kitchen. Regrettable that the average physician or tv commercial do not share this info with the public, especially since almost everyone knows someone who has been diagnosed, and breast cancer is every woman’s fear.
