> The scientists injected the nanoparticles in chicken eggs. After the chickens hatched, the scientists detected changes in the functional, morphological and microbial biomarkers in the blood, the duodenum (upper intestine) and the cecum (a pouch connected to the intestine).

This looks like those nice studies where they injected MSG into the brain of mice to show they are bad. I don't think these findings can be extrapolated to humans who encounter those nano particles through food

i mean you can also die from injecting water...

Gut health will be the big biotech thing in the 2030s, we still don't know how our gut biome works and why.

There's a lot of anecdata, but my theory is that the biome is unique to everyone so there is no one size fits all theory. (See the fecal replacement studies where thin people fecal bacteria was inserted into non-thin folks and they lost weight).

I, for example, get the worst gas from Aspartame and Asesulfame K (and maybe Sucralose, the jury is still out on that). Both proven to be 100% safe sugar alternatives with no side effects in studies.

If you have any kind of serious gut issues (or salt wasting conditions or other reason you need more salt than average), it's worth avoiding table salt which contains anti-caking additives. Get sea salt, kosher salt or canning and pickling salt instead.

Salt is a major component of mucus and the gut is lined with mucus. (For that matter, so is the respiratory tract.)

A quick lookup shows that "kosher salt" also contains anti-caking additives.

If one does this, be careful that you are getting enough iodine in your diet. They do sell some iodized sea salt. However, those generally contain anti-caking additives too.

Red 40 will give me migraines. I only found out it was the culprit because I had a blood test that showed my body reacting to it. At this point, I filter out artificial colors altogether (or at least as much as feasible).

There's enough people sensitive or allergic to Yellow 5 (tartrazine) that you can search on it. It seems that tartrazine develops when you make caramel color.

The titanium dioxide and silicon dioxide mentioned at the link are white and yellow/cream white.

I get migraines from something in food. I've done elimination diets and I'm pretty sure it's none of the obvious candidates like histamine, phosphates etc.

But there's only so much you can learn from elimination diets, they're a blunt chisel as an instrument of discovery. I'm at a loss for how to dig deeper. Where did you find someone to test your blood for something as specific as red 40? Is it an allergy test or something?

treeman793 tahun yang lalu

I was completely disabled from migraines.

My elimination diet helped migraines a lot. But not cured.

Magnesium. Vit d3/k2, omega 3, got me a whole lot farther.

FL-41 glasses helped a lot with light triggers. I stopped needing them after about a year on vitamins.

Getting rid of all scents and perfumes was a big help.

The final that actually took me from greatly improved but still severe to mostly cured?

TMJ. Dentist suggested it. I found a bob and Brad massage video.

Much to my surprise I discovered a really tight spot just above the jaw. Took me three days of massaging it for it to finally loosen up.

Boom. No more migraines.

I have to massage it out about monthly or so. It really likes to tighten up.

PaulHoule3 tahun yang lalu

I thought I had some problem w/ my shoulder and/or headaches, I never thought it was my jaw until my dentist told me I was grinding my teeth. I tried a bite guard and found the pain became highly localized in my jaw and realized my jaw was clicking. TMJ!

After two years w/ the bite guard I feel a lot better, it's been a long time since my jaw clicked or popped although an emotional event last December caused the pain to flare up again for a few weeks.

How did you decide to test that? Did you have to do many other blood tests along the way? Last time I got a handful of blood tests it felt like I lost a whole bucket of blood, hard to imagine doing anything like that by choice again

When I was seven or eight years old, red Koolaid was banned in my household because my mom maintained that the red dye made us kids act crazy/wild. One might think it was the sugar content, but my scout troop never made red "bug juice" (flavor powder packets only, in big containers of water, no sugar) either. I think there was some study done in the 70s about this, which is probably what people latched onto to explain kids' oddities, but my mom used to claim it was observable.

giantg23 tahun yang lalu

They have newer studies showing a possible link between multiple synthetic dyes and child behavioral issues, with red dye being the worst. It supposedly also affects males more than females. I believe the EU has found it credible enough to mandate warning labels on foods containing synthetic dyes.

This part is just my speculation, but I imagine many boys in school could have been medicated due to their behavioral/learning issues, which might have been the product of their diet (dyes and sugar).

I've discovered that anti-caking additives make certain kinds of cheese really crappy too. For the worst offenders it turns into a gelatin-like substance if you melt into something like chili.

Not sure exactly which additive does this, but there are definitely brands that don't exhibit this effect or not as badly.

hcazz3 tahun yang lalu

It's just cornstarch. Same reason you should never use pre-shredded cheese on a pizza, the cornstarch burns faster than the cheese does.

Because it's soluble in water, you can (and I have) washed pre-shredded cheese in a colander and dried it on a kitchen towel when it was all I had on hand, and it turned out fine.

hammock3 tahun yang lalu

>It's just cornstarch.

That is not true, and TFA refers specifically to metal oxide nanoparticles that are used as anti-caking agents

rcme3 tahun yang lalu

Shredded cheese usually does use some form of starch, however. E.g. Great Value Shredded Cheese uses potato and tapioca starch: https://www.walmart.com/ip/Great-Value-Shredded-Mild-Cheddar...

maxerickson3 tahun yang lalu

It's plenty true that cornstarch and/or cellulose make packaged shredded cheese melt weird.

Or is your argument that metal oxide nanoparticles are the only anti-caking agents that are used?

sliken3 tahun yang lalu

I've noticed grated or powered cheese tasting less and less like cheese, presumably because of cellulose, anticaking, and anything else that they put in that costs less than cheese.

I've switched to grating cheese myself, even for a single person meal, doesn't take long and tastes SO much better.

The best cheese grater for 'e is the MouliGrater https://en.m.wikipedia.org/wiki/Mouli_grater . Especially the old ones as new ones have a tendency to be flimsy.

It's great for three reasons:

1 - it's the easiest and fastest grating device for cheese 2 - it's safe. Microplanes are great but it often happened that my cheese got a little bit of finger with it 3 - the texture and taste of the cheese is amazing. I can't explain it but it seems that the strands of cheese are thinner and longer . Whether it's on Parmigiano Reggiano or on old Comté it's just beautiful.

More on topic : never buy pre grated cheese. Or any thing pre-something.

I swear by pre-ground wheat. Cannot afford the time or counter space for a stone mill.

benj1113 tahun yang lalu

I'm forced to infer the US(?) Makes much greater use of pregrated cheese compared to Europe.

Grating cheese isn't exactly an onerous task, and the result tastes better, and a grater isn't expensive, so...

xur173 tahun yang lalu

My biggest issue is cleaning the grater - for a single meal, it's nice to just be able to pour a bit from a bag and be done. If I use a grater, I have to get the cheese out, grate it, and clean the grater.

That said, I do prefer the result of the grated cheese.

klyrs3 tahun yang lalu

I made a joke about not milling my own flour (after which I did some research and found that some very reasonable-sized mills can be had for an exhorbitant fee). I actually grate my own cheese.

But! Do you make dishes with over a pound of cheese in them?

elevaet3 tahun yang lalu

Same here. But to be fair, I did have some bread made from freshly ground (and freshly dried) wheat once, and it was amazing.

Ohhhh, we used to have one of these when I was a kid. So great - much better than anything I have in my kitchen now.

(It made up for walking to school 5 miles, uphill in both directions, in the snow ;) )

IKEA sells a container set with grater lids and then a sealing lid. We get our kids to grate the cheese (and they fight over the opportunity) and excess cheese is stored in the fridge for the next meal. Or as you probably do, just grate straight onto the food.

You can also get mason jar grater lids, which work with mason jars and lids you may already have in your kitchen. Bonus, they are made in the USA. https://www.microplane.com/mason-jar-lid-grater

Microplanes are a goddamned revelation.

germinalphrase3 tahun yang lalu

Such an improvement over the dull graters I grew up with.

Apparently their patent on the chemically etched blade process expired so there should be more direct competition, but I haven’t explored alternatives.

rendaw3 tahun yang lalu

Microplanes = very small holes, right? My experience was that cheese shredded that small dissolved/melted and lost it's flavor too fast when mixed with other foods and it was a lot of effort to grate any decent amount.

NegativeLatency3 tahun yang lalu

Instead of holes one kind they make has little blades like a wood plane does, works great for parm and grating zest

giraffe_lady3 tahun yang lalu

Yeah they're only good for very hard cheeses like parmesan and friends. Useful for a lot of other non-cheese things too, good tool. Just not a replacement for a cheese grater really.

ThePowerOfFuet3 tahun yang lalu

You clearly haven't tried the ones with big teeth; grating soft cheeses like mozzarella is a dream.

benj1113 tahun yang lalu

You grate mozzarella?

Just tear it, or slice it.

SAI_Peregrinus3 tahun yang lalu

No, they have a wide variety of hole sizes in their lineup. They're just very sharp graters, far easier to use than most other sorts.

rootusrootus3 tahun yang lalu

A quick hack if you have no alternative handy is to throw in a slice of American cheese to counter the additives.

I've noticed that better quality grated cheese tends to behave better. E.g. Tillamook grated cheese melts nicely for me.

hinkley3 tahun yang lalu

Colby Jack is the least Frankensteinian of the melted cheese options. Curds of two cheeses pressed and aged together. Colby is the same microbe as cheddar (cheddar turns out to be a verb, not a flavor, and Colby skips the processing).

I go through a lot of bricks of Tillamook's Colby Jack.

hammock3 tahun yang lalu

Tillamook makes great cheese. They're also one of the only mass-produced ice creams I can find these days that doesn't have any gums or carageenan added to it

edit: they might have begun adding gums. I have to buy Jeni's or Van Leeuwen. Ought to just make my own with how little I eat anyway.

NegativeLatency3 tahun yang lalu

Yeah they have but it’s still better than most

You could also check out Häagen-Dazs if it is available in your market.

Well thank you for the suggestion and I am pleasantly surprised. I had written that brand off for a long time knowing that it was a made-up word and made by Nestle... the ingredients appear very clean and quality though

Food processor with a grating disk. (I think I have a Breville.) I am a stickler for freshly-grated cheese. This sometimes delayed dinner.

LazyMans3 tahun yang lalu

I bought a food processor specifically to grate mozzarella for pizzas. I still pretty much only use it for that reason. Hah. Used to take me like 5 min to grate a lb of cheese. Now I blast through a block of cheese with the fury of 1200 watts in 30 seconds. Amazing

JumpCrisscross3 tahun yang lalu

For me, fondue! Hand grating pounds of cheese on a box is tough. But it’s flaming garbage with the packaged stuff.

NegativeLatency3 tahun yang lalu

How much cheese are you grating?

treeman793 tahun yang lalu

Block cheese and cheese grater attachment on Kitchen aid is drastically tastier. Very quick.

Pre grated cheese? Why not just get proper cheese?

Looked at the incredients in some walmart Great Value brand hot chocolate... found silicone dioxide listed as ingredient for anti-caking. Really?? Sand?? Basically getting scammed. Wouldn't be surprised to see saw dust as an ingredient from Dollar Tree coco.

Dylan168073 tahun yang lalu

Sand (so not nanoparticles) sounds like a good choice to me. Nice and inert. What matters is how much there is.

Unless you think they're lying about it being anti-caking?

pazimzadeh3 tahun yang lalu

I thought the article was telling us that it's not inert?

edit (can't delete): oh you're talking about eating 'sand'

sbaiddn3 tahun yang lalu

Nothing thats nano is inert.

That being said even inert things can act as catalysts, and even if they don't act as catalysts, they can sterically interfere with reactions

adrr3 tahun yang lalu

I assume we eat lots of dust especially if you live in a dry climate next to a desert.

sbaiddn3 tahun yang lalu

But its not nano

Dylan168073 tahun yang lalu

The article is telling us that nanoparticles are not inert. But that's much smaller than sand or silt.

Who would have thought? Eating sand is bad for you…

Gigachad3 tahun yang lalu

That is unexpected. I’d have assumed sand is quite inert and safe. And even now it doesn’t seem very conclusive.

hammock3 tahun yang lalu

I have been told my entire life that these chemicals are safe

rising-sky3 tahun yang lalu

Fair! But a whole generation was told that sugar consumption was safe. And low-fat was a balanced diet against obesity, diabetes, heart ailments (metabolic syndrome)

NoPicklez3 tahun yang lalu

Sugar consumption is safe. The problem is that people over consume the wrong types of sugar in highly palatable foods. The same way in which an extremely high fat diet is bad for you, especially if you eat the wrong sorts of fats.

A whole generation was also taught everything in moderation, but we've not been very good at it.

I think that video is more helpful for you than it is me.

"He argues that fructose (too much) and fiber (not enough)".

Too much sugar is bad for you, too much fat is bad for you. If you eat too many foods that are high in processed sugars, you're going to increase your risk of diabetes. If you eat a balanced diet that includes fruits and other complex carbs with fibre to reduce the GI of the food, you're going to be fine.

All of this needs to be combined with some exercise.

This isn't ground breaking science, this is a Youtube video for people who have a poor diet.

rising-sky3 tahun yang lalu

I see. Well, it was definitely helpful for me, sorry it wasn't helpful for you.
