Edit: the hypothetical diet wouldn't be pure skittles, it's just replacing rice/pasta/bread/etc. with skittles and still getting the proper protein and fiber

You'd end up buying your dentist's boat.

[–] blarghly@lemmy.world 18 points 22 hours ago (1 children)

I mean... I wouldn't do this. But millions live on a similar diet every day (minus the multivitamin). Sugary cereal for breakfast with fruit flavored "juice", a fried chicken sandwich for lunch (kudos for the chicken, but then its white bread, white flour, soybean oil, and flavored soybean oil) plus a soda, and finally, say, boxed mac and cheese for dinner with a canned margarita to take the edge off.

Day to day, you will adapt and how you feel on the diet will start to feel "normal". But you will get fat, be at higher risk for any number of health issues in the long term, and will likely feel depressed. But relative to, like, starving to death, you'll be pretty healthy.

[–] Candice_the_elephant@lemmy.world 4 points 19 hours ago

Yeah the lack of fiber will do a lot of damage over time too.

[–] j4k3@piefed.world 23 points 23 hours ago (1 children)

Peanut M&M's would be better. Eating small portion sizes and more often is the main thing. Skittles will likely cause digestive issues because of the lack of fiber. How your body responds to all that sugar is also a long term issue, but age is a factor there.

I started my journey from 350 lbs to 190 lbs on Peanut M&M's, Adderall, and way too much of an internet cafe. I just ate a few when I felt light headed, but was super focused on CS/BF/CoD. I only did that for a month or so after having to move back in with family. Then I started riding bikes a lot, like 400+ mile weeks.

[–] seathru@quokk.au 11 points 23 hours ago

Ahh, the good old Jenny Crank diet.

[–] rumschlumpel@feddit.org 18 points 23 hours ago* (last edited 23 hours ago)

Would you still be eating vegetables? Eating no fiber whatsoever would probably do you in. If you're still eating sufficient amounts of vegetables, you might not need supplements at all.

And definitely do law carb if all your carbs are sugar ...

[–] rowinxavier@lemmy.world 4 points 18 hours ago

Kind of yes, kind of no.

Short term there is not a huge difference between getting sugar from complex carbs or simple carbs and most vitamins and micro nutrients will be OK with a few weeks of worse absorption and slowly lowering levels.

Medium term this would be bad, but so is the standard western diet. Carbs are not a great source for energy for a number of reasons but one of the key ones can be seen with vitamin C. Why do we not have functional pathways for making vitamin C? Our closest relatives do, the other great apes, and almost all other mammals do too. In fact as far as I am aware one of the only other mammals missing the ability to make vitamin C is the guinea pig which is especially ironic considering it was the aminal selected to understand scurvy, an extreme form of vitamin C deficiency.

We don't need anywhere near the same level of vitamin C if we are not eating sugars, complex or simple. Eating a very very low carb diet, deep into the ketogenic end, reduces the need for vitamin C. Taking someone who has symptoms of scurvy and switching them to a carnivore diet seems to reverse the symptoms fairly promptly and plenty of people eat just meat for decades at a time without developing scurvy, so it seems safe enough.

So if you look at a diet made of highly processed high carb foods like the current standard American diet you would see a measurable but not extreme change in the short to medium term, but in the medium to long term it would get worse. If you compare to a more reasonable diet which doesn't have huge amounts of processed foods or carbs in it then it would be a bigger difference.

My intuition says that I'd wind up having a headache for the rest of my life.

[–] Pogogunner@sopuli.xyz 7 points 23 hours ago

Over the long term, I suspect the sugar spikes and crashes would cause you to eat a lot more calories/sugar than a normal diet, and likely lead to diabetes.

Multivitamins are useful some a small handful of nutritional deficiencies but wouldn't come close to rescuing this diet.

[–] 14th_cylon@lemmy.zip 6 points 23 hours ago (2 children)

wtf. multivitamins are largely a marketing scam, most of that shit will just go out of your body anyway, you are paying for enhanced urine. and skittles? food source? really?

[–] blarghly@lemmy.world 9 points 22 hours ago (2 children)

Source on multivitamins being a scam? I'm aware that it is preferrable to get nutrients from whole foods - but also, my bias of "the human body isn't dumb" says that if you are significantly deficient in iron, and take a multivitamin with iron, your body will try its best to absorb the iron and you'll be better off than you would be otherwise. Plus, multivitamins are cheap, which is one of the main reasons I've heard people advocate for them - a days worth of multivitamin costs pennies, so why the hell not? It's a good hedge.

[–] 14th_cylon@lemmy.zip 6 points 22 hours ago (3 children)

https://www.hopkinsmedicine.org/health/wellness-and-prevention/is-there-really-any-benefit-to-multivitamins

significantly deficient in iron

if you are significantly deficient in anything, then take whatever your doctor recommends. but this idea people have "oh pop a pill a to get some vitamin c and others, you will be healthy" is just marketing.

[–] blarghly@lemmy.world 5 points 22 hours ago (1 children)

I mean, the context I hear the advice in is "yeah, eat a healthy diet. Take a generic multivitamin if you want - you provably aren't lacking anything, but it'll make sure you aren't." For context, I hear this advice given to people who already care a lot about their diet for the sake of athletic performance.

Also, your link didn't convince me of the above claim that you just piss out everything in a multivitamin. It didn't mention that. It just said multivitamins don't prevent heart attacks, which.... I never thought they did.

[–] 14th_cylon@lemmy.zip 1 points 21 hours ago

check the other article i have strategically hidden as reply to myself.

[–] TranquilTurbulence@lemmy.zip 3 points 20 hours ago* (last edited 20 hours ago)

Are people really expecting vitamins to heal disease? No wonder why you called it a scam. I just thought that vitamins would do their nutritional job instead of performing miracles.

[–] 14th_cylon@lemmy.zip 3 points 22 hours ago (1 children)

there is one that is slightly more in favor. so take your pick i guess

https://www.health.harvard.edu/staying-healthy/should-i-take-a-daily-multivitamin

Most studies have not shown a definitive health benefit of a daily MVM supplement for men like you. However, a recent clinical trial, published online Jan. 18, 2024, by The American Journal of Clinical Nutrition, suggests taking MVMs may help delay cognitive decline in older adults.

For the trial, 573 participants were given baseline cognitive and memory tests. Half were given one standard MVM daily, and the other half took a placebo. Both groups were unaware of which one they were given. The study participants were retested again after two years. The people who took the MVM scored slightly higher on the memory and cognitive tests than those who took the placebo.

but also says:

The grocery and drugstore shelves are full of other supplements, which are heavily promoted for all kinds of health benefits, most of which have no scientific evidence to support their use. It's always best to check with the pharmacist or doctor before taking any individual supplement.

[–] rumschlumpel@feddit.org 1 points 8 hours ago

That isn't really any better than the other link, it's pretty hard to be vitamin-deficient enough to e.g. develop scurvy even if you eat only junkfood (AFAIK even french fries contain some amount of vitamin C, and most burgers have raw lettuce and tomato). Early Sailors ate literally nothing but bread (hard tack), cured meat and perhaps fish for months at a time.

[–] FriendOfDeSoto@startrek.website 3 points 22 hours ago

Iron ≠ vitamin. You are really pissing out most of the vitamins in vitamin supplements. And when I say most it's closer to all of it.

[–] Candice_the_elephant@lemmy.world 2 points 19 hours ago

And some of them have ridiculous dosages. For example some have up to 10x the recommended maximum daily B12 amount and that can and does cause permanent nerve damage if taken daily for an extended period. My wife caught it early when symptoms hadn't gotten chronic yet, she was lucky.

[–] pyrinix@kbin.melroy.org 3 points 21 hours ago

[–] FuglyDuck@lemmy.world 4 points 23 hours ago (1 children)

No.

you need proteins. neither skittles nor the vast majority of multivitamins contain proteins. And in any case, the vast majority of "junkfood diets" suck for your health. Usually they're a gimmick to teach you about caloric intake for weightloss (and maybe some chemistry.)

[–] rumschlumpel@feddit.org 19 points 23 hours ago

OP didn't ask about only eating skittles and multivitamins, they asked about replacing "traditional carb sources" with skittles and multivitamins. Meat, eggs or hard cheese are not "traditional carb sources" by any definition.

[–] disregardable@lemmy.zip 1 points 23 hours ago

no, you do in fact need grains and fruits.

If you want to have ADHD by the amount of colorants I believe is ok.

[–] sbeak@sopuli.xyz 3 points 20 hours ago (1 children)

Artificial colours don't cause ADHD I think. And just before you ask, no, vaccines don't either.

I remember there was this one case where a particular red dye caused a form of cancer and is now out of production, which is interesting. And also Napoleon's (I think it was him?) walls had a toxic green paint that certainly didn't help his chances of not-dying

[–] BigBolillo@mgtowlemmy.org 0 points 19 hours ago (1 children)

I believe if Norway, Iceland, Sweden, Finland, Austria, Switzerland, Germany, Australia, New Zealand, Japan banned some(not all) artificial colors is for a reason. About vaccines I believe it is still a conspiracy theory.

[–] sbeak@sopuli.xyz 2 points 17 hours ago (1 children)

To note, the meta-analyses all say that more research investigation is needed for a more concrete conclusion. Additionally, they add that the studies may have had publication biases or had small ungeneralisable sample sizes. (their words, not mine)

The third meta analysis says "Improvement in the identification of responders is required before strong clinical recommendations can be made."

https://pmc.ncbi.nlm.nih.gov/articles/PMC3441937/ (first trial you linked) states that AFCs are not the main cause of ADHD, but it may exacerbate the symptoms of it. Also, they note that it may not be limited to ADHD (general effect was replicated, they said). Current status of evidence is inconclusive.

https://pmc.ncbi.nlm.nih.gov/articles/PMC9052604/ (first recent review you linked) states that the studies that show positive results (5 of 6 since 1990, 8 of 19 before) that may affect behaviour of children (but does not explicitly state that it causes ADHD) and that more research is needed for a conclusion.

https://pmc.ncbi.nlm.nih.gov/articles/PMC9573786/ (last one you linked) states that the cause of ADHD "is not known, but, along with genetic factors, it is possible that environmental factors including toxins and diet may affect symptom severity." (again, exacerbating the symptoms!) They also note that more research is necessary. "There is a need for more research to determine how these individual compounds affect humans" "More research is necessary to describe the neurotoxicity of artificial blue dyes in humans."

[–] sbeak@sopuli.xyz 1 points 17 hours ago (1 children)

I did indeed read those papers. Some of them were decently interesting actually, but none of them say "ADHD is caused by food dyes", one review paper explicitly states the cause is unknown.

They suggest that food colourings MAY (not do, may) affect behaviour and exacerbate the symptoms of ADHD, and that more research is needed.

[–] BigBolillo@mgtowlemmy.org 1 points 16 hours ago

As far as I know there is not only one thing that causes ADHD or other stuff like Autism, apparently it is more a conjunction of various factors, environmental things like diet, which includes processed food of all kinds(included colorants), hormones and additives like MSG, there are people who say radio frequency could be related also, as you said there are people who say vaccines could be related, even the use of TV, smartphones and technology in general could be related also.

Personally I believe(I don't have proof about it) that stuff is caused by a mutation of the DNA of the parents by the combination of all the stuff mentioned above. I mean I think it is not like all this stuff directly causes it but all this stuff degrades the DNA and then the children of these people have a big or small chance depending on the mutations on their parents DNA.

That's why these studies just find they could exacerbate the symptoms but don't cause it directly because what they cause is the degradation of the DNA.

The same thing with the lactose intolerance and the hormones which milk producers use to increase the milk production of cows, isn't like the hormones will cause lactose intolerance but they degrade the DNA of the parents which later is transferred to the newborn.

Anyway maybe what I'm saying could be just another conspiracy theory.

IMHO is not a bad idea to at least avoid as much as we can to consume tainted stuff.
