This article shows how the fructose industry is defending itself. Mostly by confusing the issue.
The thing about fructose is that it is not by itself poisonous. The problem only comes about for refined fructose, such as that found in cane sugar and HFCS. In those cases, fructose overwhelms the liver and gets processed by wrong pathways which result in all kinds of problems. But if you eat fructose in the form of fruits and vegetables, your body has to take a while to break the fructose out of the fruit and vegetable cells. Thus, your liver only gets a steady trickle of fructose instead of a flood of it. As a result, the liver can process the fructose correctly. Furthermore, if you eat fructose with fiber, molecules from the fiber help the liver process more fructose correctly.
Knowing this, it is not difficult to construct an experiment that shows that fructose is not harmful. All you have to do is feed your subjects the correct form of fructose (i.e., fruits and vegetables). The experiment where subjects ate large numbers of apples and were perfectly ok was quite telling.
The other defense of the sugar industry is that it is not the sugar, it is the overeating. However, refined sugar causes the overeating. One of the results of processing fructose the wrong way is that the liver does not produce the hormones that are supposed to inform the brain that you are full. Thus, refined fructose causes overeating of sugar and anything else you happen to be eating with your sugar. Personally I know I eat much more fries if I eat them with ketchup and I will eat much more steak if I eat it with steak sauce.
The fat people and diabetics are being blamed for eating too much and lacking willpower. They may be partially to blame, but it is very hard to make the correct decision when your brain's own sensory mechanisms are being hijacked and tricked. It is very hard to stop eating when you are constantly hungry. But if you cut down on the sugar you will not be constantly hungry, and then you may find that you do not even need that much will power to cut down on your calories.
In one of Lustig's videos he talks about fructose from fruit juice. He says if you want fruit juice, eat fruit. The problem comes when you drink a glass of apple juice. That's the juice from about 8 apples. Now, instead of the juice, try eating 8 apples. It's just not really something someone's going to do, it's so much work to grind through all that food. But a glass of apple juice is easy.
"Personally I know I eat much more fries if I eat them with ketchup and I will eat much more steak if I eat it with steak sauce."
Not to detract from your other excellent points but:
1 - it makes it easier to eat more because it's less dry. If you eat a bunch of fries with nothing it will turn into a huge lump in your stomach and you won't want more.
2 - insoluble fiber in apples slows fructose absorption, but a hunk of fatty meat does not? Fat slows absorption through the intestine.
3 - Vinegar is supposed to suppress appetite. Eating a pickle when your hungry will 4/6 times make you feel a lot less hungry.
I think you pretty much restated the point of the article in slightly more condensed terms. Eat sugar in moderation and you'll be fine. Eat too much and you'll run into problems. The point you added is that sugar -> less full -> overeat, which is possible, but not the point being debated.
Everytime a nutrition-related article gets posted, people always submit stories regarding their own personal unscientific weight-loss successes. Most of the time I don't even think they've read the article.
That being said, I found the article interesting, but, as a biochem major, fairly unsurprising. Fructose and glucose are fundamental elements of our body's metabolism, and metabolism is a fundamental element to life. It's what gives your cells energy to do every single thing they do. That sucrose, a compound made up of a single fructose molecule bonded to a glucose molecule, is not detrimental to your health given reasonable consumption reaches "duh" levels of obviousness. Same is true of high fructose corn syrup, which actually just contains 55% fructose and 42% glucose, a negligible difference. So it seems the only detriment to your health posed by HFCS over sucrose is the anxiety you'll get by worrying about it.
Like someone else said "TL;DR: stop eating so much, fatty." In more practical terms, eat reasonably and lift weights and you'll be fine.
Edit:
Here's some science for you:
Energy in = Energy out + Change in Body Stores (fat or muscle)
Where "energy" is measured in calories. Laws of thermodynamics ain't nothin' to f with! [1]
I didn't pay attention to my weight for a couple years, ate a lot of sweets and drank a lot of beer. Before I knew it I'd gained 30 pounds, and had a minor freakout. I decided to do three things--weigh myself every morning, stop eating sugar except for from fruit, and stop drinking. I ended up shedding 30 pounds in 90 days, and have kept it off for a full year. I didn't exercise or count calories in any way, in fact I probably upped my overall calorie consumption but I replaced the sugars with more complex energy sources like nuts. I'm not sure if it was cutting the alcohol, cutting the sugar, or both that did the trick. However, I've been letting myself have some alcohol for the past few months (wine, not beer) and haven't gained a pound since doing so, so my gut tells me it was the sugar. I definitely feel a whole lot healthier.
I did something similar during my semester in France. Stopped eating all bread and processed carbs. Vegetables, fruit and meat plus Greek yogurt. I didn't cut out alcohol though, nor was my weight loss as drastic as yours.
Lost about thirty pounds over four months (which was terrific, my girlfriend of four years dumped me the night I flew home so at least I was ready for singles' life).
I won't go so far as to call sugar "toxic" but I know that cutting it out has made me much, much healthier.
Also, I had a blood test a few weeks ago. My doctor actually wrote "outstanding" on my cholesterol report.
>I ended up shedding 30 pounds in 90 days, and have kept it off for a full year
>I probably upped my overall calorie consumption but I replaced the sugars with more complex energy sources like nuts
Unless you started exercising, these two statements are incompatible with one another (violates the first law of thermodynamics). What's more likely is you felt "fuller" from eating healthy foods and therefore consumed less calories.
Most of your changes could be explained just by calories. Beer is quite high calorie since it has so many carbs, and eating nuts satiates you faster so you end up eating less.
Alcohol itself doesn't affect weight much, though IIRC fat isn't metabolized well together with it. But it can improve your lifespan: http://www.ncbi.nlm.nih.gov/pubmed/9481115
I doubt excluding sugars from your diet made a difference, or excluding alcohol alone did it. Beer in general do not have that many calories, it is usually junk food accompanied beer is what adding a lot of calories and fat.
^^^ IMHO, since there is a chance you were consuming pound of sugar and six-pack of beer daily :)
The article takes the long winded approach to point out the rational argument about how to combat obesity that's been obvious all along: moderation. Laying the blame on sugar in general is a panacea; the problem more has to do with how efficiently sugar delivery has been engineered. Processed foods have made it so that you can eat a relatively small quantity of matter and get a huge amount of sugar (and fat).
Want to get healthy and lose weight? Cut the processed foods. If it comes in a box, don't buy it. If there are ingredients you have trouble pronouncing, don't buy it. Your body has evolved to know when you've had enough food (slowing down your eating will help too). But those foods that are designed in a lab have sugar and other "bad" stuff in disproportionately high amounts, so by the time you've eaten enough to feel full, you've eaten way too much.
Willpower requires an expenditure of glucose in the brain [1]. When one is used to a high-sugar diet, the blood sugar burns off quickly, despite being slowed by insulin response, and the body craves more, with the brain being glucose-depleted to resist the impulse. This is not to absolve anyone of personal responsibility, but like gambling, it is a losing proposition over time.
The fact is, we're all wired a little differently. Some who drink too much can simple moderate; some find the need to temporarily or permanently quit drinking altogether. Anyone trapped in the "metabolic syndrome" of a sugary diet will probably be more successful doing the latter.
Or instead of not eating boxed food, just do a research how much "bad stuff" in it and divide accordingly to meet your calories and nutrients target for a day.
Cut the processed foods. If it comes in a box, don't buy it. If there are ingredients you have trouble pronouncing, don't buy it.
I've reduced my diet to the following: apples, canned pineapple, pork steaks, canned corn, and tap water.
The advantage is that none of those contain anything artificial (except the tap water). The disadvantage is that probably no one else would be content eating only those things. But I've been forcing myself, because the alternative is empirically worse.
It's likely I'm just fooling myself. But even still, it's a huge stress relief to not feel bad about we eat.
Personally I think this is pretty extreme/bad advice. Plenty of over-processed foods don't come in boxes, and plenty of perfectly acceptable foods do come in boxes.
I've even heard a university nutritionist make the claim that sugar is just glucose. Some days I feel stupid; others, I feel other people are more stupid.
That line alone cost the article much of its credibility in my book. A scientific article should not lump all sugars together as metabolically equivalent.
"What I find frustrating about this debate is that most people yelling and screaming don’t fully define the terms, perhaps because they don’t appreciate them (forgivable) or because they are trying to mislead others (unforgiveable). The wrong question is being asked. “Is sugar toxic?” is a silly question. Why? Because it lacks context. Is water toxic? Is oxygen toxic? These are equally silly questions, I hope you’ll appreciate. Both oxygen and water are essential for life (sugar, by the way, is not). But both oxygen and water are toxic – yes, lethal – at high enough doses."
"Enzymes in the intestine split sucrose into fructose and glucose within seconds, so as far as the human body is concerned sucrose and high-fructose corn syrup are equivalent."
I'm not an expert by any means, but from what I recall that point is still widely contested.
Yes sugar is toxic because of the metabolic by-products of fructose, which is similar to the by-products of alcohol. Both are known to make freshmen put on weight.
He's a consulting research guy for the same people that benefit from HFCS. He has a bunch of propaganda about HFCS, so he is seriously bending the conclusions as much as possible in favor of it.
Here's the part where the article actually agrees that sugar is bad for you:
> Even if Lustig is wrong to call fructose poisonous and saddle it with all the blame for obesity and diabetes, his most fundamental directive is sound: eat less sugar.
WTF? It spent the whole article trying to show that sugar is ok, and then it concludes that?
I am amazed by the number of people here claiming sugar is bad. I've been eating fruits, fruit juices, milk and sodas as the main part of my diet for a few months now. I've lost weight and I feel really really good (I was in a low carb diet before and always craving carbs and feeling awful).
I've been like you in the past. But instead believing in Lustig and others, I've kept reading scientific studies and the work of Ray Peat is much more consistent.
I have found that reduced-carb and reduced-sugar diets are the best way to lose weight. I have been on "6 small servings with lots of lean protein and yogurt" and on keto-style diets (lots of animal fats, butter, and, almost 0 carbs). Both have resulted in significant loss of weight. I find that the keto-style diet gives me a very even energy throughout the day (probably because the body is slowly burning fat and there are no insulin spikes).
In turn, obesity is a strong predictor of many diseases, regardless of other factors.
In individual cases unobservable "noise" can affect the rate of gain or loss vs the estimated rate given by subtracting an estimate (calories gleaned from an activities database) from another estimate (calories written on the side of the food packet).
But when you look at population BMI vs population calorie intake, it looks suspiciously like a perfect correlation:
Which is what we would expect from a basic acceptance of freshman physics. Energy and matter are conserved. No exceptions.
Singling out fructose as some kind of super-baddy doesn't work, for the simple reason that the population BMI-calories correlation appears in countries outside the USA. Only the USA has corn politics and only the USA has HFCS in the food supply in any abundance. Yet the rest of the developed world is getting fat on the same trajectory as the USA has.
The problem with refined fructose is that it contributes to you eating more because the liver cannot process it properly and does not send the "i am full" signals to the brain. Thus, it is in fact the reason why people have higher net caloric intake.
US style food is being exported all over the world. Sodas are sold all over the world. Obesity around the world is generally correlated to the level at which US style food culture is adopted.
The correlation you want isn't BMI<->calories, it's food type<->calories. The question to be answered is whether some types of food make it easier or harder to maintain a caloric balance.
The ironic part about the hour and a half talk "Sugar: The Bitter Truth" is that all the people who it could help the most all have sugar-induced ADD and won't be able to sit through it to understand it...
Anyways I hope this recent bump from HN allows Dr. Lustig to make the talk-show rounds again.
I really hope not. I love sugar. It's also the only stimulant I can mete out in small doses that will keep me going without obliterating my concentration, as caffeine tends to do (disclaimer: I haven't tried cocaine).
I read about some research* regarding ego depletion and its relationship to blood glucose levels that was pretty interesting. Basically, they did a study with two groups of people. Both were asked to do some challenging problems requiring concentration, then both were given lemonade. One group's lemonade was sweetened with glucose, and the other with some artificial sweetener. The two groups were then asked to do more challenging problems. I can't recall the actual numbers, but the group that had glucose in their lemonade did significantly better on the second round than the other group, and the two groups were about the same on the first round.
The implication was that the brain uses glucose in its operation, and requires a certain level of glucose to function at full capacity. At least one cause of the brain fog we get after a full day's focused work is that we're low on fuel, which happens to be easy to fix. Unfortunately, it has other effects too that we might not want so much. I've been meaning to experiment on myself a bit with some glucose tabs after a long day of code, but haven't gotten around to it yet.
(*) I think that was in "Thinking, Fast and Slow" but I'm not certain now, too many similar books in between.
stimulant I can mete out in small doses that will keep me going
Consider the ''eugeroic'' ("Wakefulness Enhancer") class, described as "unproven primary mechanisms but proven efficacy". Bit scary, not something to have a habit around, but widely available through the internets.
Man. Sugar is the worst. Take it from me. I moved to the city the moment I turned 18, I didn't know much about cooking. Back in the 'burbs you'd be lucky to live within 10km of a grocery store. Downtown however, totally different story. I went NUTS with sweets and pizza.
I gained over 100 lbs in just under half a year. I was eating around 10k calories a day.
I then stuck to only these foods and have only been eating this the past couple years:
chicken
lean beef
kale + other greens
various fruit
cheese
That's it. No seasoning, nothing. I'm so much happier now. Better sleeps, better mood, better everything. My mood and days fluctuated like crazy when I didn't keep track of my diet.
I'd love to hear some opinions on the following talk from fellow HNers:
The link mentioned above is Robert Lustig MD's talk entitled "Sugar: The Bitter Truth". I found it very interesting and quite convincing, but beware that it's long (1.5 hrs) and you have to be willing to sit through a lot of biochemistry, since he goes through a bunch of cellular metabolic pathways in gory detail. If you don't care about the biochemistry, the parts about how everything we "know" about nutrition is based on shaky ground (e.g., the FDA's food pyramid, "fat in the diet is bad", etc.) is well worth watching, as is the history of how the amount of sugar in the U.S. diet has been dramatically increasing (e.g., the steady increase in the serving size of Coca Cola since 1915).
I cut out most sugar years ago, I think by not 'seasoning', you may be doing yourself a dis-service. Sugar isn't the only seasoning. There are lots you can do with herbs, oils and citrus (just stay away from vinegars which are often high in sugar).
For those who want to try restricting their diet to be more healty, a simple trick is to only shop on the outer isles of the grocery store. In more stores, you'll have the produce along one one, meats and fish along another, and then dairy and cheese along another.
Sadly, the bakery is also along a wall, so just be smart enough to avoid that one, and don't be tricked by bread, most of it has a significant amount of sugar.

Pedantically we might say that, but it's not really true.

Nice taste facits venenum -- by making us increase the dosage. Think sugar, salt, red meat, etc.
Uplifting side effects facit venenum. Think heroin, alcohol, etc.
Adverse withdrawal effects also facit venenum. Else we could easily quite alcohol, drugs, cigarettes with a little self restraint.
