Thank you for continuing to follow this series on fats. I hope by this point, you have a better idea of the role of fats and know the differences among saturated, unsaturated, trans fats and essential polyunsaturated fats. Now as we don’t consider just nutrients when eating food, let’s talk about some practical ways to incorporate more healthy fats into our diets. I’ve tried to put together as many useful ways as I know, but if you have your own swaps and suggestions, feel free to sound off in the comments.

1. Eating Oily Fish and & Taking Omega 3 Supplements – TRUTH

Consuming oily fish such as salmon, sardines, mackerel and pilchards are a great way to incorporate more EFAs into your diet. There are UK guidelines for the consumption of oily fish along with other fish and shellfish because there is a concern about mercury poisoning. They recommend two 140g portions of fish including 1 oily fish.

As I am not particularly a fan of eating fish (unless I have cooked it), I aim to get my omega 3 through supplements or vegetarian sources. There is some controversy on the usefulness of fish oil supplements as compared to eating fish, but if you do consider taking them, you should consult your medical doctor for the best advice.

Facing the Fats: Unsaturated Fats and trans-fats (Part 2)

To recap, triglycerides are what we typically call fats or oils which consist of 3 fatty acids fused to a glycerol backbone.

Fats can come from animal or plant sources, providing and assisting with the absorption of fat-soluble vitamins such as Vitamin A, D, E and K, along with essential fatty acids (EFAs). As we stated in part 1, the structure of fat has a big role in its function and you’ve probably heard lots about unsaturated vs saturated fats, trans fats or even weird abbreviations like MUFA, PUFA, EPA and DHA. So, what are these?

What are monounsaturated fats?

If you recall, saturated fats which come from animal sources, have as many hydrogens as possible surrounding the carbon atoms and can fit closely together like strands of wool closely packed to make a solid sweater. So typically, saturated fats are solid at room temperature, while unsaturated fats have fewer hydrogen atoms bonded to the carbon chain, forming kinks in the structure and enabling these lipids to be liquid at room temperature. Many unsaturated fats are available from plant sources.
