I think someone here once told me that blueberries burned up a specific b vitamin, but I don't remember which.   I correlated blueberries to a bad night for me once, and I didn't seem to have anything else bad.   Just that huge helping of blueberry pie...

Thanks! I seem to have fixed my state by eating a nice juicy beef burger. Probably I needed more zinc as I don't eat beef too often out of fear of raising my iron saturation. Liver also contains zinc but I guess its retinol content far outweights the moderate amount of zinc is has, which is needed for the retinol-binding protein production.

Now I feel fine even after eating liver and blueberries. It's always been interesting how quickly I react to dietary triggers and experience improvements, though.

@lil-chick Good memory! I once pointed out that blueberries severely affects thiamine status, because of thiaminase. If I eat a cup of blueberries for a few days I start getting weak legs, which is my sign of thiamine deficiency.

I do believe that circulating retinoic acid impairs transketolase, which is absolutely necessary for thiamine to be effective. It would not be surprising that after a while of low vA diet, the detoxing would gradually erode the stock of available thiamine.

Thanks very much 🙏 

I'm in a bind here though, as the blueberry season is gonna be over pretty soon here, and the damn berries are on sale right now. So, on the one hand, I don't eat high thiamine foods (pork, seeds, lentils), not on a regular basis at least; on the other hand, the blueberries make such a great addition to my banana milkshake that I'm ready to suffer some minor downsides considering they are still considered a very healthy food.

As for my little setback, I think I'll eat some more beef today and see how I feel by the evening. I noticed several times in the past that abstaining from read meat for a long time isn't great for me, a state which is quickly fixed by eating a small amount of it. I guess it's probably the zinc in it as chicken doesn't yield the same benefits, and my total blood protein is fine. If I go too hard on it, however, my serum iron starts creeping up. So whenever I strike just the right balance with vitamin D, magnesium, a bit of liver, eggs, cheese (calcium+k2), read meat, and other stuff, I feel awesome, ready to pump iron, do pushups, pull-ups, squats, etc. When something is off, I'm left to wonder what I've been missing.

Anyway, I still haven't been able to find a good dietary source of folate that I can tolerate. Eggs, kiwis and bananas are fine, but they provide just enough to keep my level above the lower reference range. Leafy greens are too high in carotene, and mees me up when eaten a couple days in a row. B supplements are even worse.

All year round we eat so many cucumbers.     But especially in summer.     The other night we were having fish with tartar sauce and German cucumber salad.   I realized that one was mayo with cuke and the other is cuke with mayo LOL.     It's cucumber season here now, and though I'm taking a breather from serious homesteading this year, this is one of the few things we're growing!   It's really a fruit... From google:

"Cucumbers also provide folate, an essential B vitamin that reduces stroke...It's no secret that eating a variety of fruits and vegetables every day is an effective way to prevent heart disease, and cucumbers are a refreshing option."

Another idea for you is to make a sauce out of your blueberries.  Then you can have a small taste of your blueberries on lots of things including your smoothie.   All year round.   I will post this recipe too.   This is my take on "jam" but no added pectin.

Thanks! However, this page list the folate content of cucumbers as 7 mcg, which is negligible when viewed against the RDA (400 mcg).

Blueberries contain chlorogenic acid which tends to stimulate bile flow like coffee does. Usually a good thing. Blueberries are high in phenols and would cause similar effects to beta carotenes and aldehydes if not metabolising well.

Thanks! Does it only happens with blueberries or with other foods as well? How long does it take for you to get back to normal?

Hi! Need some advice. I've been feeling a little off lately and not able to pinpoint exactly what I've been doing wrong. The issues are the usual stuff, like fatigue, slow digestion, brain fog. However, I've been eating store bought chicken noodled soup for a couple weeks. The ingredients are water, chicken, noodles, carrots (!), onions, salt, some pepper. Photos are attached. Is it possible I'm reacting to the high carotene from carrots? Especially given they are boiled and the soup itself contains fats. Would you personally have a bad reaction to a soup with such an orange color from carrots?
