I stopped taking turmeric in morning with breakfast a few months back and started to take turmeric only at night 2 or more hours after meal for my knee and to avoid iron deficiency anaemia. Glad to hear that Dr Greger advising the same.
I am very glad you covered this - I have hereditary haemochrotosis (AKA the Celtic Curse), which means my body absorbs too much iron. I was suffering from lots of random symptoms until I did a DNA test. I can get sluggish, low energy blood sugar issues, concentration issues etc. It's horrible. I will be drinking strong black tea after a meal from now on!
Hm interesting. I thought the body has mechanisms to downregulate the uptake of iron from plant sources. But it cannot stop the uptake of heme-iron from animal flesh. So if you eating only plants, that reads like it would be fine, but I don't know enough so don't quote me on this . Just a bit of info I've heard that you might look into more. I heard it in the Plant Chompers video that was specifically about iron.
@@blomegoog It may be but coffee is healthy unless taken in excess, whereas alcohol is harmful even in low quantities. Coffee is high in antioxidants, it is a fermented food which fosters good gut bacteria, and is high in fibre.
So what's the best time to drink coffee? I usually drink it after lunch but I also read that it's not good in the morning. And I don't wanna drink it late in the day
I’m wondering the same. If you avoid it for two hours after breakfast and then give yourself enough time before lunch maybe. Because otherwise you’d have to drink it two hours after lunch and that seems too late.
Very good to tackle this important subject. Thanks a lot. I have two questions:- 1. could you state the situation for someone on a whole food fully plant based diet, feeling fine, and haemoglobin in the normal range of a regular fasting blood test which I think does not measure ferritin levels? Should such a person have these beverages after meals? Or should they get ferritin levels checked in a separate specific blood test? 2. Did I understand right: at the same meal, the iron blocking effect of coffee could be cancelled by the absorbtion enhancing effect of an orange? If yes, that would suit me well indeed. Thank you.
Next study: "'The effects of reducing alcohol intake in toddlers by 50% per day' In this study, we asked a group of toddlers to reduce their alcoholic intake from the national average of 3 drinks per day to just 1-2..."
You should make a video on how iron absorption increases when your levels are low and decreases when levels are high, as it adds to confusion of bio-availability of plant sources of iron.
@@gb7168 In the UK I don't believe that it is common for our doctors to order such a test without any symptoms. I can't say that I monitor my iron intake either. But I will continue with the turmeric unless I experience symptoms for anaemia and it is confirmed with a test. Thanks
@@gb7168 I have been suffering from iron deficiency which became freaky bad on the daily dozen … I have removed tea and coffee from my diet but was having turmeric at almost every meal … I might reduce Turmeric then and consume it every two days … 😢
That's crazy. And makes sense because I'm diagnosed anemic recently and I realized everytime I have anything caffeinated my symptoms come back almost as if I didn't even take my iron supplement. Thats insane.
Been following the daily dozen for years and had to be hospitalized with a profound case of iron-deficient anemia. Still struggling with keeping up levels. Now I'm adding tons of pumpkin seeds to my smoothies that contain lots of high vitamin C fruits.
Same I had a perfect diet with lentils beans, kale,etc. and was eating lots of vitamin C … but having heavy periods and running I ended up with bad iron deficiency! I have my supplement every morning with vitamin C - and don’t eat and drink only water for 2 hours. There is a fuss about iron overload in the plant based community but iron deficiency is very common and overlooked I believe. This is my opinion and only my opinion.
I guess one question I would have is the blocking of iron positive in vegans who don't consume any heme iron or is it just really good for omnivores who do.
Unfortunately for me, being a woman of child bearing age and being vegan - led me to iron deficiency… with terrible symptoms… I take my supplement with vitamin C every morning and only eat drink coffee two hours after …
Um...what about the source of the iron? I didn't hear you mention whether the studies considered people's diets and if they were getting in heme iron from animals or iron from plants. I regularly am over 400% the RDA just from eating whole plants, but maybe my absorption is regulated by my spice, tea, and coffee intake. But none of my iron is coming from meat, dairy or eggs. I would think that if any iron was the issue then wouldn't the traditional Okinawan diet have had lots of problems due to iron? They used to eat so many greens. But even if they did have issues, I'll take living to 100 even if issues with high iron stores are there. Better than dying in the mid 70s like the average american.
I also wondered whether the studies considered heme or non-heme iron. I've also heard that iron from plant sources is less bioavailable so you NEED to eat more of it.
I don't consume heme iron (the often dangerous kind our bodies have a hard time releasing) anyway but I also always happen to be eating citrus fruit (the most common local fruit by far to me) every time I drink tea or coffee with food so I probably don't have this iron absorption issue with the coffee or tea
One key thing I learned about iron from a recent Plant Chompers video is we need to avoid heme iron (found mostly in animal foods) as much as possible, since our bodies are unable to regulate its uptake, unlike with non-heme iron from plants. To put it another way: if you're at risk of iron overload, skip the meat and eat iron-rich plant foods instead. It might just do the trick without having to resort to coffee and tea consumption to lower your levels.
Plant Chompers had 3 videos on health influencers. The ones he hand picked that lived the longest, and in the best health, and with awards and honors in their name, Dr. Kummerow, Dr. Hinohara and Dr. Denmark all said the iron in lean meat which is heme is very important.
Hey! I just made a similar comment LOL eating animal flesh forces iron on our bodies but eating plants allows our body to absorb what it needs. Glad to see the truth is getting out there!! I believe that this fact is the reason for the myth that iron from animals is more "bio-available" which is nothing more than a twisting of the truth.
@@beepbeepnj2658 That is interesting, however it doesn't change the biological fact that our body cannot regulate heme-iron and that it can regulate iron from plants. Based on the information in this video it sounds like coffee is a good way to mitigate the damage that can be caused by heme-iron which, if it's necessary to mitigate something it's probably better to avoid it all together.
@@flattlandermontgomery1524 So the 3 centenarian medical professionals I listed were wrong even though those 3 saved more lives than any YT health expert making videos at this time? Please explain where you learned a while ago about this iron myth? Please give me the names of these people where you got this information from.
@@beepbeepnj2658 I apologize, I didn't mean to be dismissive of what you said. Maybe you could elaborate on what they mean by saying that heme iron is very important. I have tabs upon tabs that I have saved with links and resources and haven't found a good way to organize them, I have to do a lot of digging to find the information. I can do that, but it's going to be a while.
Studies say yes, 76-80% in average but it also contains a tiny amount of iron contrary to tea or coffee. I dont know about Guayusa, it also contains tannins but they are not the same as in yerba mate.
true, but, whatever u would eat what's considered healthy, its still better choice and u can feel it inside, than having a junk food. especially it matters as u r older - younger ppl organisms are bit more "flexible"
Doesn't iron at a certain amount in the blood have a negative effect on the levels of free testosterone in men? As I've heard, it increases tne hormone SHBG which attaches to the circulating free testosterone thereby diminishing its effects on the male body. This occurs even if the clinically measured level of total testosterone is considered to be shown in the high range
The study he put on the screen said "black tea" so I think that's what he was referring to when he just said tea. He also mentioned peppermint and chamomile which are not true teas, but herbs, but at a different absorbing blocking rate.
Something I learned a while ago is that heme iron in animal flesh is harder for the body to regulate. In other words we absorb too much iron from animal flesh because the body can't regulate it but when we eat plants the body can limit the amount of iron we absorb if it's too much. This in my opinion is what gives rise to the myth that plant iron is less bio-available. The truth is plant iron is better for us because the body can choose to absorb what it needs and to not absorb too much. Therefore in my opinion coffee is a good option for animal eaters because it can help to prevent iron overload but for plant only eaters we probably should drink our coffee (and other iron blocking foods) away from our meals.
