Frequently Asked Questions

In moderation, olives are generally well-tolerated. However, cured olives can be high in sodium, and excessive consumption of olive oil, especially on an empty stomach, may cause digestive upset like diarrhea or cramps in some individuals.

Extra virgin olive oil (EVOO) is the best choice for combating inflammation. It is cold-pressed and minimally processed, which preserves the highest concentration of beneficial anti-inflammatory compounds, such as polyphenols.

Olive leaf extract (OLE) typically contains a much higher concentration of oleuropein than olive oil, making it potentially more potent for specific inflammatory conditions. However, olive oil is excellent for long-term dietary benefits, and the best choice depends on individual needs and consultation with a healthcare provider.

Yes, some studies suggest that extra virgin olive oil can be beneficial for gastritis due to its anti-H. pylori activity and ability to protect the stomach lining from inflammation. A traditional remedy involves taking a tablespoon with lemon juice on an empty stomach.

Experts generally recommend consuming 1 to 2 tablespoons of extra virgin olive oil per day to reap the health benefits, including reduced inflammation. This can be drizzled over food or used in cooking at moderate temperatures.

As olives mature, their polyphenol content tends to increase. This means fully ripe black olives may have a slightly higher concentration of these beneficial compounds than greener, younger olives, though both are healthy.

Yes, the Mediterranean diet, with its high consumption of extra virgin olive oil, has been proven effective in managing chronic inflammatory diseases, including those related to the gut like Inflammatory Bowel Disease (IBD). Its focus on plant-based foods and healthy fats supports overall gut health.
