Olive Oil
Research suggests that fatty acids present in olive oils may be useful in treating H. pylori infections. [10]
In a 2012 study, people who had H. pylori infections were given various doses of olive oil every day for two weeks. [11] Results from this study led the researchers to conclude that olive oil was effective a little effective in treating H. pylori.
The results from the above study were mixed, so it is difficult to judge its efficacy based on the study alone. Most studies on the effects of olive oil on H. pylori that have shown potential are in vitro studies. According to research, many foods that demonstrate antibacterial activities in vitro are not always as effective when used in vivo. [12]
To fully understand the effectiveness of this oil, more research is needed. Meanwhile, you can still use include this oil in your diet if you have H. pylori to take advantage of its potential effects. Olive oil has other health benefits besides inhibiting H. pylori growth, and it is not harmful.
