For readers concerned about fatty acids and their own healthy fat food content - this is particularly where your trigylceride reading comes in, from your normal blood lipid tests.
What upping your protein somewhat, and healthy fat content, and lowering carb content to varying levels (depending on your own carbohydrate tolerance) has shown again and again to lower trigylcerides in people's blood - ie the fatty acid level derived from food and your fat storage. Lower triglyceride numbers reflect greater health (under 1.7 mmol/L better, under 1 even better.) BUT don't take mine or anyone's word for it - you check it out for yourself! Get your blood lipids checked, note your triglyceride level, go LCHF or paleo or whatever way of eating strikes your fancy that will lower your carb content and raise your healthy fat content, and get your blood lipids done again, and note all the figures - but for this argument - the triglycerides.
It seems folks our bodies work better on this food balance. It seems that 2 million years of evolution and what we as a species were eating (in terms of carbs, as in low, and protein and fat - as in pretty high!) really DOES make a difference. And you can see it in your own blood lipid panel results.
Do note though, if you have a lot of fat stored in your body - there will be a period of time when your triglycerides (remembering that this is how you know what is happening in your own body with fatty acids) are really high, when the fat in your body is being released into your blood stream and used up and (is excreted the right word here? I don't know) - shipped out! So allow for that, if you have plenty of fat in storage, then get your blood lipids checked again after you have lost the fat. I say this with a delightful (I hope!) confidence, as I have read the research, and it happened to me. It has happened to countless people who have tried this. Because - our bodies really do seem to work this way! But as I say - don't take my word for it - check it out for yourself!
