How Much Olive Oil Per Day Is Healthy and Safe?

The Potential Benefits of Olive Oil

Olive oil has been a staple of the Mediterranean diet for centuries. This versatile oil made from ripe olives provides healthy monounsaturated fats and powerful antioxidants. Research has linked olive oil consumption to numerous health benefits:

Heart Health

Olive oil may improve several key risk factors for heart disease. Its antioxidant and anti-inflammatory properties can help prevent LDL ("bad") cholesterol from oxidizing and protect blood vessels from inflammation-related damage. Multiple studies associate higher olive oil intake with lower rates of heart disease, stroke, and death from cardiovascular causes.

Weight Management

Replacing less healthy fats with olive oil may aid weight loss and weight maintenance. In a large Spanish study, participants assigned to a Mediterranean diet enriched with olive oil lost more weight than those on a low-fat diet after 5 years. Olive oil increases feelings of fullness and stimulates the release of appetite-suppressing hormones.

Diabetes Prevention

A diet rich in olive oil may help prevent or manage type 2 diabetes. Olive oil has been shown to improve blood sugar regulation and insulin sensitivity while curbing inflammation in diabetics. These beneficial effects likely stem from olive oil's high content of healthy fats and antioxidants.

How Much Olive Oil Per Day Is Healthy?

When consumed in moderation, olive oil provides valuable nutrients and health-promoting compounds. But how much is ideal for good health?

General Guidelines

Most health organizations recommend limiting total dietary fat to 20-35% of your daily calorie intake. The USDA Dietary Guidelines suggest an average fat intake of 25-30% of calories for a 2000 calorie diet. Within this range, 5-7% (about 11-15 grams) of your daily calories should come from monounsaturated fats like olive oil.

For the average person, this equates to about 1-2 tablespoons (15-30ml) of olive oil per day. Athletes, growing teenagers, and some elderly may benefit from slightly more based on higher calorie needs. But most nutrition experts recommend capping intake at around 2-3 tablespoons daily at most.

Focus on Whole Food Sources

Olive oil delivers the greatest benefits as part of a balanced, Mediterranean-style eating pattern focused on whole, minimally processed foods like fruits, vegetables, whole grains, legumes, nuts, fish, poultry, eggs, yogurt, herbs and spices. Commercial salad dressings, spreads, and cooking oils make up a large proportion of the average American's fat intake. Choosing quality extra virgin olive oil for these uses can be an easy way to boost monounsaturated fats.

Potential Drawbacks of Excessive Olive Oil Intake

While moderate olive oil consumption offers advantages, more is not necessarily better. Here are some potential issues with overdoing your olive oil intake:

Weight Gain

Olive oil is high in calories - about 120 per tablespoon. Consuming too much adds extra calories which can lead to unwanted weight gain over time, especially if you eat a lot of processed and packaged foods that contain hidden olive oil. Be mindful of your portions.

Interactions with Medications

Very high olive oil intake can potentially make certain medications less effective by increasing fat absorption. Check with your doctor if you take high olive oil amounts.

Other Effects

In some sensitive people, high olive oil consumption may cause mild diarrhea or stomach discomfort. There is also some concern that oxidized lipids from excessive olive oil intake could have negative effects, but more research is needed.

The Bottom Line

When included as part of a balanced, plant-focused Mediterranean-style diet, 1-2 tablespoons of olive oil per day offers valuable health benefits with minimal risk. Consuming more than this has not been shown to provide additional advantages and may even cause unwanted effects in some cases.

Rather than drinking olive oil by the spoonful or overusing it as a cooking fat, focus on getting plenty of antioxidants, fiber, plant protein, and healthy fats from whole olives and olive oil integrated into homemade meals. This allows you to fully leverage olive oil's nutrition and flavor.
