Cardiologists endorse extra virgin olive oil as the best everyday oil because it is the best oil for heart health. Its high amount of monounsaturated fat and polyphenols helps lower LDL cholesterol and decrease inflammation. With cardioprotective properties supported by peer-reviewed, clinically evidence-based research showing a decrease in cardiovascular disease, I personally use it daily.

Extra Virgin Olive Oil

  • Highest in heart-protective polyphenols
  • Lowers LDL cholesterol by 5mg/dL per tablespoon
  • Use for dressings and low-heat cooking below 410°F
  • Choose cold-pressed with harvest dates

Avocado Oil

  • Ideal for high-heat cooking up to 520°F
  • Rich in monounsaturated oleic acid
  • Neutral flavor suits baking and frying
  • Contains vision-supporting lutein

Canola Oil

  • Best omega-3 to omega-6 balance
  • Works well for everyday sautéing
  • Lowest saturated fat among plant oils
  • Opt for expeller-pressed versions

*Use these oils wisely* based on cooking methods. I use extra-virgin olive oil for salad dressings and low-heat sautéing, avocado oil for very high-heat roasting and frying, and canola oil for medium-heat baking. This way, you enhance benefits while minimizing damage due to oxidation.

Be diligent in measuring portions with a teaspoon. Cardiologists believe that 1-2 teaspoons can be considered a portion of the 20-35% of total fat intake. I store them in dark bottles, away from heat, to preserve the nutrients. The most important consideration to obsess over is that if you want proven heart-protective benefits, quality is critical.

Steer clear of oils that have disproportionate omega-6 levels, such as corn or soybean oil, which promote inflammation when consumed in excess. Gradually substitute with those oils we recommend. Your cardiac health improves when you consistently make wise choices over a long period, without pushing too hard or too fast.
