Title: Iris colour change on a raw animal food diet
Post by: TylerDurden on September 16, 2009, 04:16:32 pm
I'm curious to know whether others have also experienced iris colour change like me. Please state what particular foods were related to any iris colour change(could well be that no particular food was responsible) and say what your original iris colour was and what it now is, if there was any change. For example, consuming dairy rapidly darkened my normally brown irises to an almost coal-black state over the years pre-rawpalaeodiet, my irises then changed to green or greeny brown on the outside with dark brown in the centre after a c.3 years into rawpalaeo, with only very small changes in iris colour since then.

green or greeny brown on the outside with dark brown in the centre.

As far as I remember I used to have dark irises in the past. I don't know if raw vegan diet had any impact on their colour. Currently, after 2.5 years eating raw meats, my irises are "greeny with some brown in the centre".

Good photo rawlion!  Funnily enough, my eyes look exactly the same as yours with mainly light green but with brown around the pupils.  The brown used to be much more evenly spread and they would've been described as 'hazel' eyes.

Interestingly, in contrast to Tyler's experiences, I noticed the improvement when following a Primal-type Diet incl lots of raw dairy, raw meats, raw veg juices, honey etc.  Much to my disappointment, if anything, they have darkened since being on a rawpaleo diet so I, too, would be very interested in others experiences.

I am and will continue to closely monitor my new son's eye colour.  They were a fantastic clear blue when he was born.  He's now almost 4 months old and I have sadly noticed a light brown is forming around the pupil similar to rawlion's picture.  He is solely breast fed so far but his mother does eat a cooked WAP type diet.  I do try to include as much RAF in her diet as I can and she has plenty of homemade grass-fed jerky with raw butter, raw lamb liver/heart, raw eggs, blue ice CLO etc.

Could the darkening be because you're almost or wholly RZC, now? I can't remember whether my irises were darker on my RZC trials, myself, as I wasn't interested in that aspect at the time of the experiments.

Of course, we should all be wary re common mentions in rawist circles of lighter eyes being always linked with greater health. After all, what about RVAFers with blue eyes? They can be sickly and still have blue eyes.

Yes, good points Tyler.  Many of those raw vegans seem close to death yet have staggeringly clear blue eyes (at least in the internet pictures I've seen anyway) so it's not necessarily a marker for good health.

You're right that I am not far from being RZC now - just a few herbs for flavouring with my meat/fat meals and the very occasional piece of fruit.  There are also times when I do eat cooked foods with friends to be sociable but I keep this to a minimum - perhaps once per month at the most.  However, I think my eyes had darkened again long before I'd started heading in the direction of RZC.  I'm not sure if my eye color has any significance to my state of health but my instincts tell me there is something in iridology from my own observations of other's eyes.

Lex certainly appears to have overcome many health problems and reached a state of stable good health.  Lex, have you noticed much in the way of eye changes?

Raw eggs make my eyes bluer. Instead of being a dull green-blue they become very blue.

When I was raw vegan they were grey but I was like 140lbs and unable to think so I was seriously nutrient and protein deficient.
Title: Re: Iris colour change on a raw animal food diet
Post by: Python on September 17, 2009, 03:32:27 am
Actually, I want to clarify what I said above:

When I eat raw eggs, with or without eating a fully raw diet, my eyes become a very vivid blue. Cooked food does not "pollute" my eye color as long as I am eating raw eggs. I believe this to be related at least in part to a better absorption of cysteine as that would go a long way towards explaining some of the other benefits that I have noticed on the diet which are all in some way related to cysteine.

When I was raw vegan, my eyes were grey which while being a sign of less melanin than blue eyes was due probably not to cysteine inhibiting melanin production(which I think is healthful so long as I better absorb vitamin D given my limited sun exposure) but an overall deficiency in most every major nutrient and amino acid. I also had low hormone and energy levels at the time so it makes sense that my melanin levels would have been low simply from being unable to produce any.

Holy cow, this is unbelievable! You guys finally peaked my curiosity enough to check my eye color. I was convinced they couldn't have changed color--they've been completely light-brown my whole life (except for infancy, when they were a very dark bluish color, according to my mother). I just looked and, sure enough, the outer edge of my iris has turned dark blue-green. Kind of like the outside ring of rawlion's eyes, only darker and a bit bluish. And I've only been eating mostly-raw carnivorous RPD for about a month. I'm somewhat color blind, so I'll have someone else verify this.

Thanks for tipping me off to this. Fascinating. I eat raw meats, raw eggs, suet and water currently. Mostly grassfed.

Eggs are loaded with cysteine because baby chicks need the cysteine to produce all those cute little feathers by the time they hatch. It goes without saying that growing really awesome hair everywhere has been the only side-effect I've noticed from moderate egg consumption and a "burnt feather/hair" smell coming from when I just eat too many eggs.

A co-worker said she didn't see blue in the changed part of my iris, just green, so I guess my eyes are turning green, rather than bluish green.

Yes, and I've been eating lots of raw eggs, mostly fertilized, for the past couple of weeks or so. Averaging 4-6 per day I think. I bought so many eggs one time that one of the cashiers chuckled a bit. I don't think they had ever seen a lone customer buy so many eggs (I think it was 5 or 6 standard-size cartons and 2-4 containers of quail eggs). No ill effects so far from the eggs, no change in weight, just this partial change in eye color which I agree does seem to be related.

Well, I'm disproving this, because my brown eyes are turning green.

My left eye. They still look toxic green in dim light.. I hate it. Green is not "right" color of the eye.

And yes, my eyes have changed color radically, from olive green to blue-gray.

Post by: PaleoPhil on September 18, 2009, 11:00:06 pm
I don't know whether to consider my eyes changing to green from brown is necessarily good or bad. I thought it was kind of neat at first, because my lady friend prefers green and blue to brown eyes, but I'm suspicious of a change that is coming about apparently due to an unusual amount of eggs I'm ingesting. I'm only eating lots of eggs for bulking, not as a health improvement. People living in the wild would not have been eating lots of eggs year-round. So it seems just as possible that green eyes might be less advantageous than brown eyes (maybe the brown melanin offers needed protection from the sun?). However, other noncarnivorous raw dieters claim their eyes turned green or blue too, so it's intriguing to think it might be a sign of good health. What other foods are high in cysteine that the plant-heavy raw dieters might be eating?

Too much melanin interferes with vitamin D absorption so if you're not experiencing sunburns then what's the reason for alarm? Wouldn't the betacarotene in the egg yolks protect your eyes from sun damage anyway?

I think that the reason raw vegans have a change in eye color is from an inability to make enough melanin due to a deficiency and not due to cysteine binding to the melanin precursor. Raw vegans are frail, have low-hormone levels, are tired and lazy when they're not bingeing on fruit sugar, and just otherwise look like they're ready to fall down and die if someone bumped into them.

Don't worry, I'm not at all alarmed. Just curious.

I actually wish I had a bit more melanin in my skin, as I'm paler than probably 99% of the world's population and therefore still a bit more susceptible to sun burn and to blinding people with my pale, bare forehead than I care for. However, my pale skin does seem to provide frequent merriment for other people, so it does have additional advantages beyond easier absorption of sunlight for vitamin D production. ;)

I have no idea, as this eye-color-change thing is a completely new experience for me. I'm enjoying the novelty of it and curious about this phenomenon that is new to me.

Cysteine is concentrated in the eye and liver, so maybe eating a lot of cysteine could change eye color.
"As a key constituent of glutathione, cysteine has many important physiological functions. Glutathione, formed from cysteine, glutamic acid, and glycine, is found in all human tissues, with the highest concentrations found in the liver and eyes."

This article suggests bone broth and tougher cuts of meat are better than tender cuts of meat. (tough meat has a lot of collagen).
http://raypeat.com/articles/aging/tryptophan-serotonin-aging.shtml
It goes on to say glycine, which collagen is rich in, is important for good health. Glycine + cysteine = more glutathione = better health. Probably the change in eye color is an indication of better health.

i've been really noticing lately that my irises have gone from a really dark brown to a fairly light hazelnut color. my mom even noticed. she also said that i had green eyes when i was a baby and im wondering if they'll eventually get back to that if i keep eating well. it would kind of make sense: maybe we are born with the iris color we should always have but after eating shitty food, we quickly develop darker colors around the toddler years. does this coincide with other peoples experiences? has anyone had the same exact color their entire life (even when born)? just a thought. i was really surprised mine changed nonetheless.

Yes, and that's been my hypothesis for many other health/physical phenomena also. I've noticed that it's like the clock is being rolled back to the way things were in my youth. Many symptoms that I used to consider "normal" with aging have been reversing. I think that way too many things are attributed to aging than is actually the case (though I wouldn't go as far as William on this subject ;) ). I've found that many people have a great deal of trouble accepting that some symptoms/disorders/illnesses, such as joint pains and morning stiffness, are not just a normal consequence of aging plus genes, but also are influenced by diet. Maybe they don't want to have to give up some of their favorite foods, or don't want to admit that their own behavior is the cause of much of their physical deterioration, etc.

I looked into the mirror yesterday and my eyes have deepened from an ice blue-grey to a darker blue (almost looks like it's had a bit of green mixed into the previous color to darken it) since going raw ZC. I also eat no eggs whatsoever as they bother my stomach so this couldn't be a causative affect of eggs (I've avoided eggs for years).
All I'm eating is raw beef muscles, occasional organs (heart, liver, kidney, or spleen) and lots of fat. Very rarely I'll indulge in pemmican made with raw jerky. I usually sprinkle a small amount of celtic sea salt on my muscle meats. I drink water with the occasional addition of liquid electrolytes if I'm feeling the need.

I just realized I have a photo of my eyes from 3 1/2 years ago. I'll take a photo of my eyes tonight so there's a reference to the physical change. I know this can't show a cause-effect due to a RPD because it's too long a time span since the "before" shot but it will show a noticeable change due to eating healthier. :)

i don't eat eggs often but i realized that i noticed the change after adding a small slice of liver to my daily diet. i'd say i've been doing this for about a month or so now. not sure if that had any effect...

While it's not necessary to eat eggs to change one's eye color to green or blue, they do seem to be one of the better foods at doing this. Here's an anecdote I posted elsewhere:

I also forgot to mention that a number of RVAFers have reported getting lighter-coloured eyes after consuming raw dairy. In my own case, though, raw dairy darkened my irises very quickly.
Title: Re: Iris colour change on a raw animal food diet

Fascinating. I wonder what causes the opposite responses. I also wonder why cysteine and perhaps other amino acids from eggs, meats and organs reduce melanin in the eyes while apparently increasing it, or enabling it to increase, in the skin at the same time, and why modern diets contribute to the opposite--paler skin and darker eyes.

In theory, it's been claimed that  nonwhites would get amber-coloured(yellowish-brown) eyes after going on a RVAF diet for some years with whites getting lighter-coloured eyes(more like what eye-colour they had at birth, in the latter case). No guarantee re eye-colour change, though as it seems to be a relatively random phenomenon.

"Eating raw unpasteurised milk and cream, along with juiced vegetables can change your eye colour. Mine wnet from light brwon to grey over a year on this diet; it is the result of detoxification.

This will not, however, apply to people of African or oriental descent who are born with "black" eyes. It only applies to people of european descent whose natrually blue eyes are clouded by toxins in cooked food.

My point re amber-coloured eyes comes from comments made by long-term Primal Dieters on the (closed) Primal Diet yahoo group, so I'm pretty sure there must have been some examples thereof for that data to be mentioned(of course, there may be other factors - for example, I understand that many black people in the US have Caucasian DNA as well, to some extent, which might increase the likelihood of light-coloured eyes appearing, perhaps?). I will post a comment re this on that group  to see if there is a response

I'm just curious to know of anyone of asian descent has experienced a change in eye-colour as a result of eating raw animal foods. The eye colour change seems to be more common in caucasians, but this could just be because there aren't that many asians following this kind of diet and/or posting on the boards in english.

I do know of a full-blooded Korean actress who has naturally hazel-green eyes.

I don't know if it's just my imagination, but I think my eye colour is a bit lighter brown than it was when I was younger. When I was a kid, I remember my eyes being very dark, to the point where some people would tell me my eye colour was "black" instead of brown. But recently when I looked at my eyes, I noticed they seemed a bit more golden brown, like the colour of toasted sesame oil, or dark honey. I don't know if that's because of diet, maybe since I quit eating foods I'm allergic to, but I haven't been eating raw animal foods for very long, and I'm still far from being totally raw. I guess I should find some pictures of myself when I was younger and see if there's a difference. Or take some pictures now and compare it to when I really go raw.

As a side note, I also found an article saying the some people's eye colours just lighten naturally with age:

Here is a Korean who reported that her eye color lightened on a raw vegan diet:

“I posted a reply on my eye color shifting in the other post. My eyes were a medium-light brown. Now my eyes are a very light brown, almost tan. The dark rink around the iris is blue when the light shines directly in my eyes. The blue is becoming more intense. I'm Korean so brown is fairly normal. Also, while I have been 100% raw vegan (6 mos) I now do eat some cooked foods and some cheese and raw egg yolks. I believe the cooked is slowing down the process. In the beginning, I didn't see anything but dark gray then I could only see a hint of blue in the ring. When I look in the mirror and the light shines directly into the eye, the ring is a brilliant ocean blue. I believe my eyes will turn entirely blue when I become more raw. I see hints of blue under the honey color and my eyes are more translucent.” – Therese, http://www.sunfoodpages.com/cgi-bin/forum/ultimatebb.cgi?ubb=get_topic;f=6;t=000049;p=

Hey everyone. Has anyone noticed a significant color change in their eyes since starting the diet?

I red somewhere that Aajonous claims his eyes were dark brown when he was sick, and after a few years on the Primal diet they turned blue.

Please comment as to how long you've been on the diet, and what you've noticed as far as eye color change. Also comment how strict you are on your diet, and what foods your diet typically includes.

My eyes have gone from dark brown to almost an orange brown with some green in them. I've been following a raw paleo lifestyle for almost a year now, but have eaten raw meat occasionally for about 3 years.

I typically eat raw eggs, beef, bison, fish, and chicken. Nuts and veggies, some raw dairy when I can get it (mostly cheese).

Thanks. I noticed my eyes are lighter brown than they used to be. But they have a dark ring around the brown of my eye.

I'm hoping after a few years of strict rpd I'll notice some changes.

Wow, cool thread. My eyes and skin always look better when eating raw free range eggs whole or just the yolk.

Since I have been extremely high raw to 100 percent raw which is what I am trying to do now, I have noticed my eyelashes literally growing.

I do a raw paleo but I do eat sprouted Buckwheat groats.

I eat raw wheat germ sometimes, not very much so I am not completely paleo. I am a raw foodist who eats animal foods. Interesting thread indeed.

I wish that I had the guts to do raw free range liver. Sometimes I eat steak tartare but I haven't progressed to raw liver. I have no problem with raw fish. :)

I wondered if supplements that are supposed to boost glutathione would also trigger more of this phenomenon of reducing the brown/melanin in the iris (and thus revealing more green, blue or gray color).

One such supplement is Guardian Ultrathione, which Art De Vany believes has reduced the gray in his hair:

(http://artdevanyonline.com/uploads/3/1/1/9/3119807/4517778.gif)

And an animal study jibes with this:

"hair graying ... is attributable to a loss of melanin produced by oxidative stress, thus raising the possibility that hair graying constitutes a signal of resistance to oxidative stress in wild boars. Our results suggest that the degree of melanization is linked to GSH levels in wild boars and that their antioxidant damage shows senescence effects." http://www.ncbi.nlm.nih.gov/pubmed/?term=graying+hair+glutathione (http://www.ncbi.nlm.nih.gov/pubmed/?term=graying+hair+glutathione)

And hair graying is known to be reversible in humans: http://www.natureworldnews.com/articles/1745/20130503/bye-gray-hair-researchers-find-way-reverse.htm (http://www.natureworldnews.com/articles/1745/20130503/bye-gray-hair-researchers-find-way-reverse.htm)

On the other hand, it looks like his wife has a fair amount of gray hair, though she looks great overall and she also has T1DM.

But I Googled and I did find some people reporting lightened eye color from glutathione supplements:

"Yes, glutathione can lighten eye color. I experienced this myself. After 7 months of taking glutathione supplements, people have been asking if I were wearing contact lenses, which I wasn't.

I don't know about KB though as it's not "real" glutathione."

Iodine too:

And Iodine is known to increase glutathione levels: http://www.ncbi.nlm.nih.gov/pubmed/7685786 (http://www.ncbi.nlm.nih.gov/pubmed/7685786)

Though oddly I found no reports of NAC supplements (NAC is supposed to boost glutathione production) doing this.

There is a scientific explanation for how cysteine and glutathione may lighten iris color:

"In uveal melanocytes, the quality and quantity of melanin vary with race and iris color. In the uveal pigments, pheomelanin is often present in addition to eumelanin (21-23). Pheomelanin is a lighter colored, yellowish pigment that is formed when cysteine or glutathione is present during the oxidation stage of dopa (24). 1,4- benzothiazynylalanine, derived from cysteinyldopas, is proposed to be a key intermediate in the biosynthesis of pheomelanin (24). The quantity of uveal melanin in eyes with dark-colored irides is greater than that in light-colored eyes (21,23,25). Uveal melanocytes contain both eumelanin and pheomelanin. In cells from eyes with dark-colored irides (brown and dark brown in color), the amount of eumelanin and the ratio of eumelanin/pheomelanin is significantly greater than that from eyes with light-colored irides (hazel, green, yellow-brown and blue in color) (23). The quantity of pheomelanin in uveal melanocytes from eyes with light-colored irides is slightly greater than that from dark-colored irides, although the difference is not statistically significant (23)." http://www.youreyesolutions.com/blog/item/role-of-ocular-melanin-in-ophthalmic-physiology-and-pathology (http://www.youreyesolutions.com/blog/item/role-of-ocular-melanin-in-ophthalmic-physiology-and-pathology)


There are even reports of glutathione supplements and injections lightening skin, and it has become all the rage in Asia:

Glutathione as an oral whitening agent: a randomized, double-blind, placebo-controlled study.
http://www.ncbi.nlm.nih.gov/pubmed/20524875 (http://www.ncbi.nlm.nih.gov/pubmed/20524875)
"Oral glutathione administration results in a lightening of skin color in a small number of subjects."

http://www.usc.edu/CSSF/History/2010/Projects/S1804.pdf (http://www.usc.edu/CSSF/History/2010/Projects/S1804.pdf)
"majority of the subjects tested experienced a significant lightening of their skin tone especially for those who took the pill and use the lotion" (although one subject developed spots on her face)

> "Animal tests showed that a high cysteine level (the main component of glutathione) lowers melanin production."
> "Another study on glutathione as a skin whitener will be released next month, November 2011, conducted by dermatologists from the Philippine Dermatological Society (PDS).

The study was conducted among 40 respondents who were asked to drink 500mg of glutathione capsules in 10 weeks. Only 14 users finished drinking the pills in the controlled group. Of these, 11 manifested minimal whitening of the skin."
http://www.abs-cbnnews.com/-depth/10/10/11/white-skin-comes-price (http://www.abs-cbnnews.com/-depth/10/10/11/white-skin-comes-price)

"experts have raised four theories to explain the possible whitening effect of the tripeptide, based on animal and in vivo studies using melanoma cell lines. Glutathione may directly deactivate tyrosinase, the main enzyme in melanin synthesis; sop up free radicals and peroxides that promote tyrosinase activation and melanin formation; or enhance the depigmenting abilities of melanocytotoxic agents. Another proposed mechanism is the triggering of a pathway that shifts the production in eumelanin (black to brown pigment) to pheomelanin (yellow to red-brown pigment)."

SCD (the Specific Carbohydrate Diet) could potentially also increase glutathione levels.

"Acute LPS injection produced a significant Glutathione (GSH) reduction"

LPS = a microbial toxin that has a lot of negative side effects, including antioxidant reduction.

I learned that Denise Minger reported that her increased lightening from brown to hazel irises occurred while she was on her raw vegan diet, which is rather interesting.

I got a few replies when I mentioned this topic in my 'introducing myself' thread, so I thought I'd post here too. . . Have any of the original posters continued to monitor eye colour and experienced more changes? My own colour change has been slow but is definitely noticeable now.

I did not have any noticeable green in my eyes as a child or a SAD adult. Hazel/green colour started showing up shortly after going raw 6 years ago (looking back at pictures) but I always considered my eyes to be brown until recently (new acquaintances have commented on them being 'green', which prompted me to look this up) They are hazel or green depending on the light (full-spectrum). The close up below was taken this week under a high-efficiency light bulb. The one in the black t-shirt is near a semi-transparent window on a sunny day two years ago. I have no idea about conditions on the other two, but I know I never had any green in my eyes as a kid because I used to literally pray for my eyes to turn green. Maybe I always knew they were supposed to be?
