Reply lionofgod9 says: May 8, 2019 at 2:43 pm TALK ABOUT HAIR, DHT ************************************************* Reply OZSA87 says: May 8, 2019 at 2:56 pm For those who literally cannot wait 0.075 mg/kg body weight (cyanide), 15g ground flax seed (about 2 tbsp) has 3.3mg cyanide. To make it easy, a 100kg person can eat 5~ tbsp (about 35g~) ground flax seed in one meal (up to 3 meals a day with at least 1 hour between meals but safest levels were at 2 hours). For a small person, 50kg, that's about 2.5 tbsp 3 times a day, 2 hours apart each is safe. Considering most people only eat 2 tbsp once a day, it's impossible to get any real side effects, according to the study at least.

In Sweden, the highest daily dose was reported to be 80 g ground linseed, given as “fibre shock” in a private health spa (Rosling 1993). Usually, high doses are up to 15 g three times a day in case of traditional herbal medication to treat or prevent constipation (EMA 2006), and this dose is safe with respect to possible acute toxicity of cyanide. " My interpretation is that it's safe when eaten in normal amounts and preferably not on an empty stomach.

Reply Tomoe Yamagawa says: May 8, 2019 at 5:00 pm I've never noticed any effects when eating flax seed in the current quantities I do, so I'm going to assume it's safe unless you eat over a certain threshold determined by body mass. I wait until your next video to either debunk my current hypothesis or confirm it. Reply Laurie Paris says: May 8, 2019 at 5:14 pm Forget Cyanide, what about the high levels if Cadmium in flax? Reply Lionelyy says: May 8, 2019 at 5:16 pm Oh no, a cliffhanger! You are horrible 🙁 Reply Lohit Kapoor says: May 8, 2019 at 5:19 pm If you look at the paper he is mentioning in the end, you can see that about 5mg cyanide consumption is limit for a 70kg person. 50gm linseed have about 11mg cyanide. So, I guess 2 tablespoons of flaxseed (20gm) a day would not cause cyanide toxicity. But I would listen Dr Greger's next video on same topic again. Reply B A says: May 8, 2019 at 5:32 pm My grandmother had an apricots tree , we ate 20-30 kernels at a time, few had very bitter taste which we simply spat it out.

Reply Julien Kim says: May 8, 2019 at 7:49 pm I am a cyanide detoxifying machine – hear me roar. Reply r say says: May 8, 2019 at 7:53 pm Here's the answer to the cliffhanger: 100G (2/3rds cup) may be too much if it's all you eat, but < 80g (1/2 a cup) is fine (from the paper he cites at the end, quoted below) "The relatively slow release of cyanide after ingestion of freshly grinded linseed results in a lower hazard potential. Indeed, no reports on cyanide poisoning after consumption of linseed were found in the literature. The ingestion of dif-ferent doses of the study linseed (7.5–100 g) by test person No. 5 resulted in peak levels of cyanide overproportion-ally increasing with increasing doses (Fig. 3), caused by the constant metabolism rate (at higher doses) and occur-ring despite increasing tmax values allowing more time for detoxification. With the highest dose, the cyanide peak level of 42.3 μM reached may potentially be associated with first clinical signs of toxicity. However, this is a very high amount of linseed hard to ingest quickly (caloric con-tent 370–380 kcal per 100 g), and in order to meet worst-case conditions, it has to be eaten on an empty stomach directly after grinding by a machine (chewing of the hard seeds is not effective enough and very time-consuming), without consumption of other foods. In Sweden, the high-est daily dose was reported to be 80 g ground linseed, given as “fibre shock” in a private health spa (Rosling 1993). Usually, high doses are up to 15 g three times a day in case of traditional herbal medication to treat or prevent consti-pation (EMA 2006), and this dose is safe with respect to possible acute toxicity of cyanide."

Another example is tomato seeds that mostly survive our digestive track because not only they have protective cover, but also they are hard to bite on! The seeds are toxic because, in our symbiotic relationship with fruit trees, we are not supposed to eat the seeds, and in cases where we have no choice but eating the seeds (cucumber and tomato for example) the toxin does not harm us. In cases where the seeds are not supposed to be eaten (in apples for example), the apple seeds taste bitter; they are telling us: hello, not the seeds dummy! Just because our body can handle some toxins, it does not mean we should eat more of it! Our body can get rid of some cholesterol, but I would not eat ANY of it. I have never been able to find scientific proof that humans are naturally designed to eat seeds, grains, or root vegetables; all I have heard is that humans have been eating them and survived to be healthier than meat eaters (which is true); or that our saliva contains amylase, so that we eat potatoes! Again, the reason for amylase is that in case fruits we eat are not ripe, we can handle some starch. But, does that mean we are evolved to eat seeds, grains, or potatoes? I think the answer is no. I stay away from all seeds, grains, and tubers (of course, also animal products, extracted sugars and oils, no controversy about how terrible they are for us, not on this site!), and have cured my diabetes and a number of complications caused by it; I do not feel or tested like I am in need of anything grains, seeds or tubers can provide me. Last time I even had a common cold was in March 2014 (I record them)! I admire what Dr. Greger does with his site and books; this is just a "graduate" level comment for those who have kicked their addiction to animal products and processed crap advertised as food by "food" industry! (The symbiotic relationship I described above I first heard from Loren Lockman's site) Reply Paul Perrin says: May 11, 2019 at 5:17 pm Do flaxseeds exist in nature?

All of our food is created by 10 main manufacturers who have destroyed billions of animals in areas where there was previously no agriculture in nature. But now it’s all full of pesticides and sugary fruits and vegetables. Reply Michael Greenwood says: May 13, 2019 at 12:31 pm So this may explain why raw flax seeds have been effective in curing cancer, especially breast cancer. It must be the cyanide, the same reason bitter almonds have been effective in curing cancer. Flax seeds actually seems like a better alternative anyway since we can fine tune the dosage easier as it contains a lower dosage of cyanide. Reply inGods2hands says: May 14, 2019 at 4:07 am Bake the flax seeds whole in your oven at 275 for about 30 min stirring every 10 min, cool and freeze until ready to fresh grind a small batch,,,,,,80% cyanide gone and they taste so much better. After listening to Paddison Program on YouTube and heard his Rheumatoid Arthritis was much better after switching from flax to chia, I changed from all flax to half chia……..much better.
