"We found that among Puerto Rican women, the combined intake of onion and garlic, as well as sofrito, was associated with a reduced risk of breast cancer," lead author Gauri Desai said in a statement.
The team noted they specifically evaluated onions and garlic, because both foods are rich in flavonols and organosulfar compounds.
“These compounds show anticarcinogenic properties in humans, as well as in experimental animal studies,” senior author Lina Mu explained.
They looked at Puerto Ricans, because they consume more onions and garlic than those in the United States and Europe. Puerto Rico also has lower rates of breast cancer, compared to the U.S. and Europe.
