I noticed that almost all types of cooking oil (vegetable oil, olive oil, peanut oil, etc) contain some saturated fat. Since saturated fat is known to be a contributor to heart disease, then could you simply remove the saturated fats from the oil to make it healthier?
To summarize:
Trans fat is the bad one and is even banned in many countries including the USA. It is formed as a byproduct when making many processed and fast foods.
You should get less than 2% of your fat calories from trans fat - preferably you should avoid them at all costs.
Saturated fat isn’t as bad as trans but it’s still not beneficial, the jury may still be out on exactly how bad it is, but it’s not healthy so it should be limited.
You should get less than 10% of your fat calories from saturated fat
Unsaturated fat is healthy, it’s good for you and it’s required in our diet as our bodies need it and can’t make our own.
I feel like my calorie tracking app is really harsh about saturated fats
It gives a D grade to even the tiniest bit of coconut
Might be because fats are very energy dense. They net about 9 calories per gram. However, if the app is only tracking calories without context, it is going to miss calories-over-time and satiety. Fats tak longer to metabolize and tend to be good at triggering and maintaining feeling sated.
A lot about health and diet isn’t understood very well. There are a number of advocates for saturated fats over PUFAs, with some (but not universal) evidence to support it. It’s entirely possible that it’s a case of correlation vs causation, but nothing has been proven with certainty.
