Debunking myths about olive oil

Myth: Heating olive oil destroys its health benefits.
Fact: While heating olive oil can cause some degradation of its polyphenol content, the primary fatty acids (MUFAs and PUFAs) remain stable at normal cooking temperatures. In fact, studies have shown that the antioxidant capacity of olive oil can actually increase when heated to moderate temperatures (Pellegrini et al., 2001).

Myth: Light olive oil is lower in calories and healthier than regular olive oil.
Fact: Light olive oil refers to the color and flavor of the oil, not its calorie content or nutritional value. Light olive oil undergoes more processing and refinement, which can result in a lower polyphenol content compared to extra virgin olive oil. All types of olive oil contain the same amount of calories and fat per serving.

Olive Oil Substitutes

Studio photos of the most common olive oil substitutes and olive oil alternatives.

For individuals who cannot consume olive oil due to allergies, intolerances, or dietary preferences, there are several olive oil substitutes available. The following table compares the nutritional content of common olive oil substitutes:

SubstituteCalories (per 100g)Total Fat (per 100g)Saturated Fat (per 100g)Monounsaturated Fat (per 100g)
Avocado Oil884100 g12 g70 g
Coconut Oil862100 g87 g6 g
Grapeseed Oil884100 g10 g16 g

Avocado Oil: Avocado oil is a nutrient-dense alternative to olive oil, boasting a similar fatty acid profile with high levels of monounsaturated fats. It has a high smoke point, making it suitable for cooking at higher temperatures. Avocado oil also contains beneficial plant compounds, such as lutein and zeaxanthin, which support eye health. However, avocado oil tends to be more expensive than olive oil and may have a slightly different flavor profile.

Who should avoid olive oil?

While olive oil is generally considered safe for most people, some individuals may need to limit or avoid its consumption. People with a rare olive allergy should avoid olive oil entirely, as it can trigger an allergic reaction. Additionally, individuals with gallbladder issues or those who have undergone gallbladder removal may need to limit their intake of high-fat foods, including olive oil, as it can exacerbate symptoms. As with any dietary change, it is always best to consult with a healthcare professional to determine if olive oil is appropriate for your individual needs and health status.

Can I eat olive oil daily?

Yes, incorporating olive oil into your daily diet can be a healthy choice, as long as it is consumed in moderation and as part of a balanced eating plan. The FDA recommends consuming about 2 tablespoons (23 grams) of olive oil per day to potentially reduce the risk of coronary heart disease. However, it is essential to keep in mind that olive oil is still a calorie-dense food, so it should be used in place of other less healthy fats, rather than in addition to them, to maintain a healthy calorie balance.

Can dogs eat olive oil?

Yes, dogs can safely consume olive oil in moderation as a healthy addition to their diet. Olive oil can provide several benefits for dogs, such as improving skin and coat health, aiding in weight management, and supporting brain and joint function. The recommended serving size for dogs is about 1 teaspoon (5 ml) of olive oil per 20 pounds (9 kg) of body weight per day. However, it is crucial to introduce olive oil gradually and consult with a veterinarian to ensure it is appropriate for your dog’s individual needs, as some dogs may be more sensitive to high-fat diets.

Can cats eat olive oil?

Yes, cats can safely consume small amounts of olive oil as a supplement to their diet. Olive oil can provide several benefits for cats, such as promoting skin and coat health, improving digestion, and reducing hairballs. However, it is essential to introduce olive oil gradually and use it in moderation, as cats require a primarily protein-based diet. The recommended serving size for cats is about 1/4 teaspoon (1.25 ml) of olive oil per 5 pounds (2.3 kg) of body weight per day. Always consult with a veterinarian before making any significant changes to your cat’s diet.

How long does olive oil last in the fridge?

Storing olive oil in the refrigerator can help extend its shelf life, but it is not necessary for most households. When refrigerated, olive oil can last for up to 18-24 months, depending on the quality and initial freshness of the oil. However, refrigerated olive oil may become cloudy and solidify due to the cold temperature. To restore its liquid state and clarity, simply remove the olive oil from the refrigerator and let it stand at room temperature for a few minutes before use.

Can you freeze olive oil?

Yes, you can freeze olive oil to extend its shelf life even further. Freezing olive oil can help preserve its quality for up to 6 months beyond its normal shelf life. To freeze olive oil, pour it into an ice cube tray or small, airtight containers, leaving some headspace for expansion. Once frozen, transfer the olive oil cubes or containers to a freezer-safe bag or container for long-term storage. When needed, thaw the desired amount of olive oil in the refrigerator or at room temperature before use.

How to tell if olive oil is bad?

There are several signs that indicate olive oil has gone bad and should not be consumed. The most common indicators of spoiled olive oil include a rancid smell (similar to old nuts or crayons), an off-flavor (such as a strong, bitter, or sour taste), and a change in color (usually becoming darker or more yellow). Additionally, if you notice any visible mold growth or separation of the oil into different layers, it is best to discard the olive oil to avoid potential health risks.

How long is olive oil good for?

The shelf life of olive oil depends on various factors, including the quality of the oil, processing methods, and storage conditions. Generally, an unopened bottle of olive oil can last for 12-18 months when stored in a cool, dark place away from heat and light. Once opened, olive oil is best consumed within 1-2 months for optimal freshness and quality. However, some high-quality, well-stored olive oils may maintain their freshness for up to 6 months after opening.

How to keep olive oil fresh?

To keep olive oil fresh for as long as possible, it is essential to store it properly. Keep olive oil in a cool, dark place away from heat and light, such as a pantry or cupboard. Avoid storing olive oil near the stove or in direct sunlight, as exposure to heat and light can cause the oil to deteriorate more quickly. Store olive oil in an airtight, opaque container, such as a dark glass bottle or stainless steel container, to protect it from oxygen and light. Lastly, always close the container tightly after each use to minimize air exposure and maintain freshness.
