Thanks for the great tips and such an invaluable website. It’s easy and delicious to keep a big jug of orange juice in the fridge and sip on it occasionally 🙂

b b,
What about a small glass of orange juice?

“In other words, I wouldn’t worry about it.”

Thanks! I’m happy to go with that advice. I don’t often track with Cronometer anymore, but it was just something that stuck out. Have changed the upper-limit and will leave it there.

Thanks, again. All the best for ’22

bmb,

I’m not aware of any reliable measurements of the average intake of manganese for vegans, nor have I ever tried to measure my own. While it’s theoretically possible that high manganese intakes are having a negative impact on the health of some vegans, we don’t have any evidence of it. If you see that there are particular foods pushing your manganese intakes especially high, and you can conveniently replace such foods with others, then it might be worth doing, though I’m not convinced that it is. In other words, I wouldn’t worry about it.

I also just found this vide:

Pretty much agrees with you on major point, but still cautions keeping within the guidelines, as often as possible. Haha! What fun 😉

Thanks for taking the tine to reply. And yes, I did realise it was all covered. But I got to the end of the post and still didn’t feel very confident. It wasn’t so much in what you said, but in that Red Cronometer bar being set so low, and at ‘difficult’ levels for vegans (Surprises me that the average vegan would be getting so low, given common reliance on grains).

Do you think it’s ok to change the upper-limit, then? Also, would be curious to know what you and the vegans in your circle average at…if you feel happy to share.

Thanks, again

bmb,

The entire article is an attempt to answer the question you’ve posed. This is probably the most relevant excerpt:

Manganese toxicity resulting from foods alone has not been reported in humans, even though certain vegetarian diets could provide up to 20 mg/day of manganese.

While juggling certain foods within Cronometer, with the intention of hitting daily goals, I keep coming up against (and blowing through that 11g upper-limit). Seems that oats, potatoes and rice, chick-peas and tvp are causing issues. It’s not like they are in huge quantities, either.

Is there any cause for me to be worried when going over, and is there a safe figure I can change the limit to?

Thanks 🙂

Can you explain what evidence you have that copper toxicity is a major issue for vegans and vegetarians? Theoretically, I understand that vegans can have high copper intakes and that their low zinc intakes could contribute to higher copper absorption, but I’m not aware of any verified cases of copper toxicity in vegans.
