Consistent consumption of diets rich in allium vegetables, such as onions and garlic, may significantly reduce head and neck cancer risk.
This research work was carried out to determine the association between the consumption of allium vegetables and the risk of developing cancer of the head and neck. Researchers systematically analyzed data extracted from 8 case-control studies that examined 7082 subjects and 4590 cases.
Researchers found out that regular consumption of diets high in allium vegetables, such as garlic and onions decreased the likelihood of developing cancerous cells and tumors in the head and neck. According to this study, generous intake of onions was found to be particularly effective in preventing laryngeal cancer. The results of this study show that high intake of allium vegetables may help protect individuals from carcinomas of the head and neck.
