MCT = medium chain triglycerides. Body likes these as an easily digestible / convertible fat source that doesn’t require full digestion (cf long chains like olive and nut oils). Can be converted quickly to ketones and thus a source of energy for brain. Demonstrated as helping stabilise BG and improving insulin resistance. Helping body learn to burn fat over carbs. Other benefits possibly antimicrobial and anti inflammatory. A few pple do find it adds weight more quickly; those with bigger issues in heart and liver fat storage. A key thing to ask is - what’s the source? Usually coconut oil (good) and/or dairy; but often palm oil (‘bad’). There really isn’t any truly environmentally friendly palm oil source despite marketing claims (market is distorted by developing economies ripping out native tropical forest to plant palm oil (often the Amazon) as well as disenfranchising indigenous peoples from their lands. When it’s grown in a rich western country - the successful intensive farming methods outcompete those in developing countries (which leads to further price distortion). It’s rare to know the origin of most palm oil. Often it is sourced and amassed at wholesale level - and on sold. It can be quite a processed thing (or not). Choose coconut (relatively unprocessed) origin if you can. You will do yourself a favour (coconut oil has more and varied of these MCTs); and help the environment (broadly). It will be more expensive; but if we can reduce interest in palm oil it won’t be worth it to rip up native tropical forest so often. I try to boycott palm oil products (where possible). Most of eg Tesco’s bakery goods are palm oil based. A change they made some years back that was price motivated. I hope I am informing - not preaching (too much!). We can’t all make perfect choices all the time (including me) but understanding is important.
