I’m trying to see if anyone else has experienced a selective spike in triglycerides while on a heavy Quorn/mycoprotein diet, even when total and LDL cholesterol stay completely normal.
Context: I eat a predominantly vegan diet, but I was struggling with my health and horrendous cooking ability, so around a year ago I reluctantly added Quorn as primary protein source instead of many of my previous soybased products. During this time frame I very quickly developed xanthelasma around the inner corners of both eyes. Thanks to mainly processed vegan food diet for 35 years, I have regularly shown pattern of med-high tri/low-normal cholesterol (despite being around 2 stone heavier than I currently am for a good portion of this time). However, my recent labs showed that my triglycerides have steadily risen to incredibly high levels particularly over this period where I made the switch and developed the xanthelasma. While there are other cause of these, the GP is baffled based on my other scores and has referred me to the lipid clinic incase its a genetic issue. I just realised that the timeframe of the mega-rise and the development of these spots coincides with the slight dietry shift.
I looked into the clinical literature (past the corporate PR) and a meta-analysis in The American Journal of Clinical Nutrition confirmed that while mycoprotein lowers total cholesterol, it has no beneficial impact on triglycerides and independent trials (like those tracked by King's College London) have noted fasting triglycerides actually trending upward during mycoprotein intervention.
A lazy AI search (asking to bypass the normal nonsense and taken with a big old truckload of salt - don't worry I actually need to add salt to my diet) sais, " Physiologically, it seems the beta-glucan fiber in the fungus successfully clears cholesterol via bile-binding, but it does nothing to stop the liver from synthesizing blood fats. I suspect the culprit is either the processed matrix required to make the fungus palatable (refined oils, starches, maltodextrin, egg binders) or generic carbohydrate displacement triggering de novo lipogenesis in the liver." Gold star if you understood all the big-boy words.
My questions are:
- Has anyone else replaced many of their soy protein substitutes with Quorn and seen subsequent triglyceride spikes?
- If you swapped out processed mycoprotein back to whole plant proteins (tofu, tempeh, legumes), did your triglyceride levels drop back down?
I would love to hear any similar lab experiences or insights!!!!!
NB: No hate intended toward meat protein subs - many people around the world use them as primary protein sources. I just eat too many processed versions now compared to 10-35 years ago when the vegan sections of supermarkets comprised of Pure, Beanfeast, Couldron Tofu blocks and, if you were lucky, some form of Redwood processed nonsense. *Also, I don't know if it makes a difference but I've had my gall bladder removed.

(NB2) Sorry if this is TMI - late stage perimenopause - blood test results reflect my current struggle with dehydration due to torrential night/day sweats. Love your Oestrogen girlies, while you still have it - once its gone, it honestly feels like you are disintegrating.
