Doctor Hoang Thi Hang, from the Department of Nutrition at Tam Anh General Hospital, Hanoi, states that there is currently no research indicating that drinking olive oil on an empty stomach in the morning improves skin and hair or enhances digestion. Mixing the oil with lemon, honey, or orange juice only makes it easier to consume, not more effective.

Doctor Hang notes that consuming olive oil directly on an empty stomach can negatively affect the digestive tract, causing symptoms such as: nausea, bloating, and indigestion, especially for individuals with sensitive stomachs or gastroesophageal reflux disease. People with a history of gallstones, acute or chronic pancreatitis, or those who have had their gallbladder removed may experience more severe cramping, abdominal fullness, and heartburn if they consume a significant amount of olive oil.

Individuals with digestive disorders like irritable bowel syndrome (IBS) are prone to abdominal pain and diarrhea when consuming large quantities of extra virgin olive oil directly. Furthermore, long-term use of olive oil without monitoring total caloric intake can lead to excess energy, weight gain, and negatively impact lipid metabolism.

Olive oil offers many health benefits when used correctly. AI-generated image.

Olive oil truly maximizes its benefits when used correctly, specifically by replacing less healthy fats like saturated fats and being consumed in reasonable amounts as part of a balanced diet. Instead of direct consumption, integrate olive oil into your cooking for quick stir-fries, salad dressings, dipping bread, or mixing with soups, porridges, and broths. When olive oil is consumed with meals, fat-soluble vitamins (A, D, E, K) and antioxidant compounds are absorbed more effectively by the body.

Healthy adults can consume 15-30 ml of olive oil daily, depending on their nutritional status. Individuals who are overweight, obese, or in a weight management phase should use less than the recommended amount. Doctor Hang advises anyone who experiences symptoms such as: abdominal pain, nausea, vomiting, jaundice, or prolonged diarrhea after consuming olive oil to stop and seek medical attention.
