WHAT FATS ARE HEALTHY?
This is such a common question in clinic! Perhaps it will serve you too?
For heart health we all know polyunsaturated & monounsaturated are key. Which is why the Mediterranean diet is often cited & seafood or oils like extra virgin olive oil are mentioned. Omega 3 from seafood, lamb & wild meat and also seeds (linseed, chia, h**p hearts etc) can regulate hormones & reduces inflammation.
But we also need good quality saturated fats for hormonal health & vibrant skin. Did you know that coconut oil & tallow is known to be anti-aging to the skin?
Then comes the question of what oils we should cook with?!
Polyunsaturated oils (PUFAs) like canola, rice bran, & other seed oils are easily turned into toxic trans fats as they can only handle low heat. Olive oil (mix of monounsaturated & polyunsaturated) should only be used for dressings, marinades etc. PUFAs when cooked can increase oxidative stress & inflammation that adds to CVD risk. Overheating PUFAs can also cause the formation of unhealthy trans fats, which are known to increase harmful LDL cholesterol and raise the risk of heart disease. Mind blown?!
Monounsaturated oils like sesame, peanut, avocado oils have a slightly higher burning point which makes them better for cooking at low to moderate temperatures. They are better for the heart too! Avocados, nuts (almonds, cashews, pecans) seeds are some other sources to add to the diet.
But the best oils for cooking? The sadly, & incorrectly vilified saturated fats which have the highest smoking points so are better for stirfries & roasting or frying. Coconut oil (especially if not bleached in the oil refining process called copra), tallow, or non bleached lard, duck fat etc are some examples. These also lower stroke risk & while saturated fat can raise LDL cholesterol, it may raise a less harmful, larger type of LDL cholesterol, while also raising protective HDL ("good") cholesterol. It’s all about the type & the quality & quantity!!
Also deep frying using seed oils is really dangerous for our health & is a key reason why cardiovascular disease continues to sky rocket. If you must do this use a saturated fat like in the old days!
Finally the food most contributing to CVD & obesity? Refined carbohydrates. Mind blown again?
What I’ve learned to do is to keep a range of oils for different functions & flavours in my kitchen. This provides a variety of health benefits also!
I hope this serves you!
Shine bright!
