@mtlfilmstudio Your post says that we should eat unsaturated fats...That sounds scientific...But my reasoning is the way u use fat makes it more important.
1. If you want to use fat for cooking and deep frying. PUFA is not good. Why?
A. because it has low smiking point (Starts smoking and hydrogenation as much lower temperature).
B. High absorbility (high amount of fat get absorbed per unit volume of food)
C. Higher number of double and triple bonds between carbon atoms, which forms the precursors for formation of Trans fats.
PUFA and MUFA are good when u cook food at temp lower than their smiking points. PUFA and MUFA is good for low temperature things like salad dressings, etc.
Now, coming back to your original question about Butter and Cheese (which contains very high level of saturated fats), both of these are healthy as these are sources of good cholesterol (HDL)...and their are other health benefits associated with cheese and butter. If you need referece to these I will send you recent Scientific paper from which these statemnets have been taken.
Now, as you have said I pretty confused and I am misleading people about nutrition, I would rather say that I am just doing what I have studied from research papers.
Cholesterol:
Cholesterol has been tagged as bad food and is associated with heart diseases.
The truth is there are forms of cholesterol which are good and there are forms of cholesterol which are bad.
Cholesterol froms 50% of membrane structure.
It provides substratre for Cortical hormones (Glucocorticoids, Sex Corticoids and mineralcorticoids)
7- dehydrocholesterol is precursor for Vit-D3 formation.
There are lot of stuff which we can cite and keep on arguing. My point is moderartion is key to health.
