What are the side effects of a shot of olive oil a day?

4 min read

While the Mediterranean diet features olive oil prominently for its health benefits, taking a daily shot can have unexpected drawbacks. This concentrated dose can overwhelm the digestive system, contribute to excess calories, and potentially interact with certain medications. For most people, incorporating olive oil into meals is a safer and equally beneficial approach.

Quick Summary

Excessive olive oil, such as a daily shot, can cause digestive discomfort, like diarrhea or nausea, and may lead to weight gain due to its high caloric density.

Key Points

  • Digestive Upset: Taking a large, concentrated dose of olive oil can cause nausea, stomach cramps, and diarrhea, especially on an empty stomach.

  • Calorie Overload: A single tablespoon contains around 120 calories, and a daily shot can easily contribute to excess caloric intake and unintentional weight gain.

  • Drug Interactions: Olive oil can lower blood pressure and thin the blood, potentially interacting dangerously with medications for high blood pressure or blood thinners.

  • Displaces Healthy Foods: Prioritizing a shot of oil can mean missing out on nutrient-rich whole foods, which offer more comprehensive health benefits when consumed with olive oil.

  • Gallbladder Risk: The oil stimulates bile production, which can cause discomfort for individuals with gallbladder issues or gallstones.

  • Moderation is Key: Experts recommend incorporating 1-2 tablespoons of olive oil into meals, as part of a balanced diet, rather than consuming it in large, concentrated doses.

The trend of drinking a daily shot of olive oil, popularized by wellness influencers, promises enhanced health benefits, but this practice can lead to notable side effects. While olive oil is a core component of a healthy diet, especially the Mediterranean one, consuming it in large, concentrated doses is different from using it moderately with food.

Digestive Discomfort and Gastrointestinal Issues

One of the most immediate and common side effects of taking a daily shot of olive oil is digestive upset. The high-fat content can be difficult for the body to process all at once, especially on an empty stomach. This can lead to several unpleasant symptoms:

  • Diarrhea: Olive oil can act as a natural lubricant for the digestive tract. While this can help with constipation in small amounts, an excessive dose can have a laxative effect, leading to diarrhea.
  • Nausea: Some individuals find that drinking a straight shot of oil is unappetizing and can trigger feelings of nausea or stomach upset. This is particularly true if the body is not accustomed to such a high intake of fat at once.
  • Stomach Pain and Bloating: Overloading the digestive system with fat can lead to general stomach discomfort, pain, and bloating as the body works to process the large quantity of oil.

The Calorie Conundrum and Potential Weight Gain

Olive oil is calorie-dense, with one tablespoon containing approximately 120 calories. A typical "shot" often constitutes one or two tablespoons, or even more for some trends, significantly increasing daily calorie intake without adding much volume to a meal. If these extra calories are not accounted for and burned off, they can contribute to weight gain over time. For individuals already managing their calorie intake, adding an extra 120-240 calories or more per day can easily derail their weight management goals.

Displacement of Other Healthy Foods

Excessive olive oil consumption can also displace healthier foods in the diet. While it is a healthy fat source, it lacks the fiber, vitamins, and minerals found in whole foods like vegetables, nuts, and seeds. Prioritizing a concentrated dose of oil over a varied, balanced meal can lead to a less nutritionally complete diet. The synergistic effect of consuming olive oil with other healthy foods, like vegetables, often enhances the absorption of nutrients. Taking it alone misses this benefit.

Contraindications and Health Risks

For certain individuals, a daily shot of olive oil can pose more specific health risks:

  • Gallbladder Issues: Olive oil stimulates bile production. For individuals with gallbladder problems or gallstones, this stimulation can cause discomfort or even exacerbate existing conditions.
  • Blood Sugar and Blood Pressure: Olive oil is known to help lower blood pressure and blood sugar levels. For those on blood pressure or diabetes medication, taking a large daily dose could cause levels to drop too low, potentially leading to issues like dizziness, weakness, or hypoglycemia. A consultation with a healthcare professional is crucial for anyone taking these medications.
  • Medication Interactions: Olive oil has natural blood-thinning properties. People taking blood-thinning medication should be cautious, as the oil can enhance the effects of these drugs.

How to Safely Enjoy Olive Oil

The key to unlocking olive oil's many benefits without the side effects is moderation and context. Experts recommend consuming between one and two tablespoons per day, typically incorporated into meals.

Moderate Consumption vs. A Daily "Shot"

Feature Moderate Consumption (1-2 Tbsp with meals) Daily "Shot" (Excessive amounts)
Digestive Impact Generally well-tolerated; can aid digestion Can cause diarrhea, nausea, and stomach upset
Caloric Impact Easily integrated into daily calorie goals Significant and can lead to unintended weight gain
Nutrient Absorption Enhances absorption of fat-soluble vitamins from food Less effective, as it can displace nutrient-dense foods
Health Context Part of a balanced dietary pattern like the Mediterranean diet Often a standalone habit promoted by wellness trends

Conclusion: Prioritize Moderation for Maximum Benefit

While a shot of olive oil a day may be touted as a quick health fix, the potential side effects, including digestive issues, caloric excess, and medication interactions, outweigh the unproven benefits of drinking it straight. The real magic of olive oil lies in its role as a healthy fat within a balanced, varied diet. By drizzling it over salads, using it to roast vegetables, or incorporating it into dressings, you can reap its well-documented cardiovascular and anti-inflammatory properties without the negative repercussions. As with any significant dietary change, it is always best to consult a healthcare professional, especially if you have pre-existing conditions.
