This kind of attitude is absurd and counterproductive. There's a long history of people demonising particular food groups and it gets in the way of developing actually healthy food attitudes. It used to be fat, now it's sugar. Sugar is not "literally poison". What it literally is is the body's primary energy source and a requirement for survival. The fact that eating too much of it is bad for you doesn't make it poisonous. Everything has a median lethal dose (LD50), including water. You can perfectly healthily enjoy a moderate amount of sugar as part of a varied diet just like you can healthily eat a moderate amount of any food as part of a varied diet. Extreme diet fads and the demonisation of entire food groups work against moderation and variety which are what we actually need in our eating habits. None of this is to say there isn't a huge sugar problem in modern society, ofc. What I'm saying is the problem is excess, not the consumption of it at all, and demonising it as "poison" and attempting to eliminate it entirely is not the way to bring about moderation.

Is there ever a benefit to adding refined sugar to anything, though? We know there's a benefit to eating fruit and vegetables or arguably to eating dairy, and these foods contain sugar, but when would you want to add more of it? Or is it like alcohol in that it's mostly useful for enjoyment? Long bouts of exercise like a marathon or the Tour de France or medical conditions like diabetes are the only exceptions I can think of where you'd want to instantly flood yourself with glucose.

It's literally poison." 2) and it can be a good idea if otherwise someone would suffer from caloric deficit dangerous to health and eating more food is not viable (yes, this situation is unusual)

    Sugar is the worst substance for public health ever. It's literally poison. Its hyperbole meant to convey a sense of how bad sugar (particularly added sugars) is to the health of the population. Sugar is in everything (more hyperbole!) in the U.S. America by and large is addicted to sugar and it’s very bad for us. Everything is over sweetened. Can’t even buy bacon without sugar added in some form or other.
    - cinntaile 3y ago
      Hyperbole usually leads to a lot of unnecessary discussion where people tell you that it's an exaggeration and so on. A good old meta-discussion to eventually conclude that their stance on a topic was pretty similar after all.

        Charitable interpretation by listener is indeed an important part of productive conversation. But charitable, I.e. Not intentionally or accidentally disingenuous statement by the speaker is also an important part. "You should know what I meant" rarely leads to good outcomes, not the least because typically any 4 people will have 5 Completely different but equally confident interpretations on what was so obviously meant :-) Anyhoo. Yes sugar can be good and sugar can be bad. "It's literally poison and worst thing ever" does not productively move the needle of the conversation, almost regardless of interpretation.

  Main benefit is that it sells more, whatever has the most sugar added might come out on top in a/b testing.

  Yes, there's a benefit. Sugar is beneficial in moderation. On the subject, see biochemist Ray Peat's writing.

I won’t defend Robert Lustvigs position entirely. It’s rather extreme. But I think you need to watch his stuff before trying to criticise it. Glucose is the body’s primary energy source. Yes. But not fructose. (And sucrose, which is what’s commonly referred to as sugar, breaks down to fructose and glucose as you may know). His argument is that fructose is processed by the liver. Hence the idea that it is a kind of toxin (not a “poison” if I understand the terms correctly). Everything can kill you with a certain dose. But some substances are not safe - and will damage your body - with any dose. Alcohol is definitely one of those. Fructose? Maybe. I don’t know enough about biology to tell if Lustvig is wrong or not. I’m on the skeptical side still
- leephillips 3y ago
  Our close primate relatives seem to eat a lot of fruit. It’s a traditional part of the diet of any human society where it’s available. The idea that fructose is a toxin dangerous at any dosage doesn’t seem remotely plausible.

    First, our primate relatives can easily eat a lot of meat and prefer meat if given. They do not have a lot of meat available in wild, but can occasionally eat it in the wild too. When they have meat available, they eat brains (fat) first: https://www.nationalgeographic.com/animals/article/chimpanzees-monkeys-brains-animals-predators https://www.nationalgeographic.com/animals/article/chimpanze... Second, they ferment fruit because fruit is always slightly poisonous (fructose). Third, after being close to our primate relatives for some time, our ancestors spent a lot of time hunting, which is not a trait of monkeys we know. They eat more varied meat diet than any predator known, did that for a long time, much longer than (now) we eat crops. Fourth, we have much higher normal percentage of fat in our body. For men, the normal fat percentage range is from 18% to 22%. Our primate relatives have much less normal fat, for most primates it is less than 9%. Our primate relatives sport bodybuilder's or high performance athlete's fat range just living their life. As with alcohol, fructose is not a toxin in small doses, because liver can handle it (especially when it is fermented into lactic acid). But it is a toxin in doses we usually experience now. Look for "non-alcoholic fat liver syndrome".

  Do you mean the naturally occurring sugars (shown in the macronutrient label) or added sugars in the ingredient list?
  - narag 3y ago
    If it's in the ingredients list, it is added. There's also a macronutrients table in every packaged article. There is exactly one common brand of mayo that has no added sugar. One. And there's no way to buy sugar-free versions of many other kinds of food, from fried tomatoes sauce, sausages, etc. that were traditionally made without sugar for centuries. It's a plague.
- Broken_Hippo 3y ago
  If you go in a supermarket in EU almost every food product contains sugar. That just means that the item contains sugars. It doesn't mean that we've added sugars to it. A fresh apple has sugar. A fresh tomato has sugar. Many if not most fruits and vegetables do. It shouldn't be a surprise that the canned/frozen varieties have a bit of sugar on the label.
  - avdlinde 3y ago
    If the label contains sugar, it was added and not inclusive of other whole ingredients. You can buy canned apples (ingredients :apples) and canned apples (ingredients :water, sugar, apples). Guess which costs more.

Glucose in blood is one of the sources of energy, not the sugar itself. Is it primary source of energy? I don't think so, because of successful application of ketogenic diets. A person weighting 100kg should have less than 10 (ten) grams of sugar in a blood. This is less than 40 calories circulating in the blood of this 100kg person. The same person should have less than 10 (ten) grams of ketones in the blood and it is equivalent to less than 90 calories cirrculating. Ketones are much more efficient energy source, they are twice as energy-dense. Glucose use needs a quarter of energy stored in the glucose, while fat (ketones) need only 3 (three) percents. Glucose needs insulin, fat (ketones) does not. Glucose (which is not even table sugar!) is not a main source of energy in the body. I also think that "variety" is a fad, just like other "extremes" you mentioned.

Sugar isn't poison. Blood-sugar spikes are poison. It's not a big deal to chug a bottle of Gatorade in the middle of a basketball game, your body uses that energy right away. It is a big deal to chug a bottle of Gatorade while lounging in front of some screen when your body has nothing useful to do with all that sugar. Simple carbohydrates such as pasta and potatoes break down quickly and can also cause one's blood-sugar to spike.
- tsco77 3y ago
  White pasta has one of the best insulin indexes of common foods. They're complex, not simple. Common misconception.
  - mrangle 3y ago
    True. Over time, I noticed less undesirable weight fluctuation and even weight loss when eating pasta. Also, it felt like a light meal. The trick is to not eat pasta with bread. Many people forget about the bread that they commonly combine with pasta and then blame the bloating and weight gain on the pasta that they had. I'd imagine that cutting out red sauce, which commonly has added sucrose, would be better still. Pasta is unique in that it seems to be beneficial, in terms of glycemic load, when eaten on its own. But combining it with other foods, but especially bread, may render it more taxing than other foods. Which is a common trait of food combinations.
    - tsco77 3y ago
      And wine to circle back to our topic at hand. But simple pasta and fish dishes appear quite often in the "blue zones" around the globe. Something I should do a better job of eating more of.
- specialist 3y ago
  Yes and: As you know, sucrose is composed of glucose (good) and fructose (bad). As I understand it, fruit has fiber which protects the body from fructose (blocks metabolism), and we still benefit from the glucose. I still add sugar and honey and other sweets to my drink and food. Cuz I'm a fiend. But I do now try very hard to avoid straight fructose.
achenatx 3y ago
eating sugar is not a requirement for survival. You can eat zero carbs and survive just fine. Not so for fats/proteins.
- mrangle 3y ago
  As someone who has a couple of decades of zero sugar fasting, strict paleo, and ultra low calorie dieting under his belt, this isn't true. There's nothing just fine about what happens when muscle glycogen depletes after several days of true zero carb dieting. Even strictly cutting out starch becomes problematic after some time, though my experience is also that humans will get unique health benefits from doing that for stretches. Which avoids the trouble of all-in zero carb.
  - Aerbil313 3y ago
    The guy in the video doesn't advocate for zero carb, just to clarify. Traditional diets in native populations worldwide are all varied and very different, some don't eat carbs and yet they are healthy. Probably something to do with their lifestyle also.
firewolf34 3y ago
People love their absolutes. Makes it easy to understand complex topics by breaking them down into "rules of thumb", and in the case of "sugar is poison" has double-reinforcement via a emotional element.
Aerbil313 3y ago
I wrote a good reply, then closed the tab on it. Just watch the video and decide for yourself. The culprit is fructose (a toxin almost as strong as ethanol, only consumable by the liver), the energy source it glucose and sugar is half parts each of them. The guy explains it down to very metabolismic reactions.
