"Although all fats have an equal calorific value, they are thought of as 'good' or 'bad' according to their contribution to heart disease. In this respect, polyunsaturated fats are 'good'......Excessive intake of any fats is thought to contribute to cancer, although polyunsaturates are thought to be the worst."
I'm confused...polyunsaturated fats are good and worst at the same time?
Polyunsaturates are good if you want to avoid heart disease, but bad if you want to avoid cancer.
The text is talking about a dilemma faced by people who wish to eat healthily. We're always being told that polyunsaturated fats are better for you because they are less likely to give you heart disease; but what most people don't realise is that they are more likely to give you cancer.
So which do you prefer: Heart disease or cancer? That's the dilemma.
