FAQ
1. What is the healthiest cooking oil overall?
There isn’t one single “healthiest” oil – different oils have different benefits. Olive oil, especially extra virgin, is a great all-purpose choice because of its heart-healthy fats and antioxidants. But it’s best to use a mix of oils to get a range of nutrients and benefits.
2. Which oils are best for high-heat cooking?
For high-heat methods like frying or roasting, go with oils that have a high smoke point, such as avocado oil, refined canola oil, or high-oleic sunflower oil.
3. Are saturated fats in cooking oils bad for you?
Not necessarily. Saturated fats, like those found in coconut oil or ghee, can be part of a balanced diet when used in moderation. What matters most is your overall fat intake and the balance of fats in your meals.
4. Should I avoid seed oils like canola or sunflower?
Seed oils have gotten some mixed opinions, but refined versions are generally safe when used in moderation. The key is to balance them with oils higher in omega-3s, like flaxseed or walnut oil, and avoid excessive processed foods that already contain high amounts of omega-6 oils.
5. Can I reuse cooking oil?
Reusing oil once or twice for frying is generally okay, but make sure to strain it and store it properly. However, repeatedly heating oil – especially at high temperatures – can lead to the formation of unhealthy compounds.
6. What oils should be used raw or unheated?
Oils like flaxseed, walnut, hemp seed, and pumpkin seed oil are sensitive to heat and should be used in cold dishes like salads, dips, or as a finishing drizzle. Heating them can destroy their nutrients and change their flavor.
7. Are flavored or infused oils healthy?
Infused oils can be healthy if the base oil is good quality and the infusion ingredients are safe (like herbs or garlic). Just be cautious of storage and shelf life – some infused oils can spoil faster than plain ones.
8. How should I store cooking oils to keep them fresh?
Most oils do best in a cool, dark place, tightly sealed. Some oils, especially unrefined ones like flaxseed or walnut, should be kept in the fridge. Always check the label and give oils a quick sniff – if they smell off, they may have gone rancid.
