Fascinating, luckily I love coconut and I'm a Pacific Islander. But it raises a very good question about eating ancestral foods!

I was recently eating Brazil nuts and thought they tasted just like coconut and look like mini coconuts.

Also begs the question of why VAERS data is not released by race when we know race is obtained and matters ????

So well expressed, Chris. As a writer, I want to take a moment to appreciate your writing.

Explaining how the hemachromatosis gene affects people by picking a specific food and specific cultures really made this pop out and impact me in a way that the last article about it just didn’t hit me.

I know I’m a hemachromatosis carrier – not homozygous, but still on the spectrum – so I need to pay attention to these issues. I deeply appreciate the time and thoughtfulness you’re putting into these articles, because sometimes it takes more than one to get it across to people.

Glad to be a subscriber!

I have found that I cannot digest it all that well, French, Canadian, Romanian heritage...

The key principles are: regionality, seasonality, ripeness and freshness.

Don't give the Eskimos a tropical or Mediterranean diet - and vice versa!

Follow what people traditionally ate.

Of course, apply common sense.

Is this the same for coconut water and shredded coconut?

Does this apply to other palm products?

Hi Chris, Just wanting to make sure there are not 2 typos in this paragraph where it talks about absorption of MAGNESIUM in regard to eating coconuts that are very rich in manganese. Does coconut also have high levels of MAGNESIUM? I don't quite understand how the one impairment affects an impairment of the other mineral.

"Coconut is very high in manganese, which is great if you have no impairments in your regulation of magnesium absorption, because it’s also super-convenient as one of the few magnesium-rich, potassium-rich, low-anti-nutrient sources of fat."

Thank you, Chris. This is important information for me, but a little sad lol. I've got one H gene which occasionally drives my ferritin up a bit. Possibly another of those HFE's you mentioned is pitching in to make me not just a carrier. Anyway it's not a big deal for me, as I've got good doctors. However, what feels like a big deal is that I'm intolerant/allergic to wheat, dairy, and eggs. I tend toward the Perfect Health Diet, with potatoes, rice, grass fed beef, good oils, and veggies, but oh how in love I am with So Delicious coconut milk, yogurt, and ice cream! Since I read your recent articles, I've been frantically busy with my pencil and calculator trying to figure out just how much I can get away with. Meanwhile I'm going to join your Masterpass, and an even bigger reason why I'm doing this is that my daughter has two genes, an H and an S (if I'm remembering correctly) and, I've just learned, a manganese problem with their well water (which they are fixing.) Thank you for your very important work.

This is very interesting but I'm not interested in genetic testing despite the fact that I have some “headaches, irritability, insomnia, depression, loss of balance”.

Lately I've been having most of the symptoms of B12 deficiency including severe insomnia.

My GP/NP said a blood test showed I have high B12 but I don't think it was a MMA test.

Today it felt like I'm dying but the worst part is that where I live (rural south Georgia) there are *no* 'nutritionally aware' medical professionals.

So how do I deal w/ what may be hemachromatosis or some SNP?

PS

I've been eating an oz or so of coconut chips off & on most days for a few months now, so who knows?

Thank you! Will manganese overload show in a hair test?

My Wife suffers from “headaches, irritability, insomnia, depression, loss of balance” , coconut however we don’t eat. What tests could we conduct to see what food affects her?

Thank you! What about using coconut oil for cooking? In home-made toothpaste? Appreciate

What do you think of the claim that humans absorb only 1-5% of dietary manganese? I'm not arguing for high coconut ingestion, but if you agree about manganese absorption, then generous amounts of coconut may not be detrimental. High coconut usage is sometimes seen on videos from the raw vegan community in making coconut yogurt, etc. https://ods.od.nih.gov/factsheets/Manganese-HealthProfessional/

Thanks for interesting article. Is coconut water also reach in manganese? And can one have iron and manganese overload while having low ferritin or is it is really rare?
