Experts from a UK university caution that the belief olive oil on an empty stomach aids the stomach lacks solid science. The practical advice is to add olive oil to salads to supply healthy fats for daily needs.
There is a common notion that olive oil can coat the stomach lining when taken without food. Some claim this coating protects the stomach and intestinal mucosa and even aids digestion. A frequent internet tip suggests consuming two tablespoons of olive oil each day.
While olive oil brings a range of beneficial substances, such as antioxidants, polyphenols, and fatty acids, there is no strong scientific evidence showing improved digestive function from drinking oil on an empty stomach. For perspective, two tablespoons of olive oil equate to roughly 28 grams of fat and about 238 calories, which is about 19% of the daily value typically recommended for an average adult. This highlights the importance of mindful portion control in daily fat intake.
For balanced nutrition, the recommendation is to incorporate moderate amounts of olive oil into salads and to pair them with other filling, fiber-rich foods. Olives and nuts offer healthy fats and additional nutrients, making them valuable complements in a well-rounded diet.
Historically, the idea that bread or other starchy foods pose danger has been challenged by nutrition science, and many practitioners now emphasize practical, evidence-based eating patterns rather than extreme beliefs. In everyday life, the focus remains on consistent, moderate fat intake and a variety of nutrient-dense foods to support gut health and overall well-being.
