Sugar in Fruit

I partially agree with Tigersword, sugar is sugar and 1 gram of sugar is 1 gram of carbs, eat whatever you want as long as you hit your carb/fat/protein targets.

Fruit sugar is something known as FRUCTOSE

http://en.wikipedia.org/wiki/Fructose

"Fructose is broken down by the body slowly and is converted into
SUCROSE and GLYCOGEN. Fructose is often recommended for, and consumed
by, people with diabetes mellitus or hypoglycemia, because it has a
very low Glycemic Index (GI 23) relative to cane sugar."

The way i look at it is, if you are hungry you should eat. It is far better to eat a piece of fruit than a chocolate bar.

Fruit is fine, the benefits of eating it instead of unhealthy options far outweigh the sugar content.

Fructose is not converted into sucrose or glycogen. Fructose is a component of sucrose, Sucrose is a molecule of fructose with a molecule of glucose. Fructose is generally converted into glycerol, not glycogen. Glucose is converted to glycogen. Also, there are hundreds of different sugars found in fruit, it's not all fructose, there's plenty of glucose, sucrose, maltose, galactose, and other sugars in fruit. In fact, there are plenty of fruit that have more sucrose than anything else.

If you're going to link to a Wikipedia article, you might want to read it first, and not pretend to quote something from it that isn't true, or even in the article.

Served.

I always go over as a result of fruit and have still managed to lose. It's summer. I live in Southern California and drive past strawberry fields daily. Produce is all around me, and it's fantastic.

My thought is this - I cannot think of a person that became fat (or stayed fat) just because they ate too much fruit. Thus, I am not worried about it.

Negatory dude.

Well, apart from the fact that is, when the liver is full of glycogen then the fructose path is conversion to fat., ready for reconversion at a later date, or not as the case maybe.

But then it all goes a bit scaremongery and received wisdom rather than sciencey.

diabetes, hat eating and strawberries

This is fructose sweetened and yes I mean, High Fructose Corn Death

Consuming fructose-sweetened, not glucose-sweetened, beverages increases visceral adiposity and lipids and decreases insulin sensitivity in overweight/obese humans. Stanhope KL, Schwarz JM, Keim NL, et al. J Clin Invest. 2009 May;119(5):1322-34. - cited from an article on about.com

...overweight and obese subjects consumed glucose- or fructose-sweetened beverages providing 25% of energy requirements for 10 weeks...

The study above basically suggests that if you're obese, you probably shouldn't drink a fast absorbing liquid source of sugar that represents 25% of your calorie intake. That's about a 200g dose of sugar in 1 shot. That's about 5-6 cans of coke, consumed all at once.

This pretty much has zero relevance to typical fruit consumption.

Sugar is sugar except...when it comes with it's friends Fiber, Vitamins, and Minerals. I track all my fruit consumption and I don't worry about the sugars since fruit sugar is pretty much the only source of sugar for me - I'm not eating sweets, don't eat bread, etc.

This pretty much has zero relevance to typical fruit consumption.

Thank you.

It is the data result between fructose and glucose, are you saying that the test group is not relevant.

But you are right, not typical to eating fruit, but does demonstrate fructose.

It demonstrates a rather stupid amount of fructose in the form of a fast digesting liquid in an obese population. Taking that data and making blanket statements (not directing this comment at you) about fructose is inapplicable unless you're using that same context.

What we CAN take from this is that it's probably not a good idea to get 25% of your food intake in the form of cola within a short period of time. Luckily we don't need pubmed to tell us that.

AND CALORIE TARGET....

This is offtopic.

A bit all over the place and untidy but I love that study, was an interesting read. Thanks for the link, vtach.

However, your numbers are off by far Sidesteal.

Based on the average female test subject (age 52, weight 84 kgs, bmi 29.4, body fat 43%) we're looking at around 1800~ cal on lightly active TDEE. %25 percent of that tdee in sugar is around 115 grams of fructose ~ 4 cups of orange juice. Fat gain on test subjects especially in males are surprisingly great (intraabdominal fat gain in men: +18.1% ± 5.1%, fat mass in men: +4.4% ± 0.8%). Excluding the beverages, they're on 55% complex carbs, 30% fat and 15% protein. Also it's worth noting that the females in the study are postmenopausal.

The study isn't about HFCS like vtach suggested either. The subjects were given their fructose (or glucose) dose in 3 servings with each meal. The beverage was fructose (or glucose) mixed in unsweetened Kool-Aid. 32 subjects, it's not too shabby considering how terribly hard it is to conduct any experiment on human subjects.

Foods and beverages in the US are typically sweetened with sucrose (50% glucose and 50% fructose) or high-fructose corn syrup (HFCS), which is usually 45%–58% glucose and 42%–55% fructose, rather than pure glucose or fructose. We have reported in a short-term study that the 23-hour postprandial TG profiles in male subjects consuming 25% energy as HFCS (55% fructose) or sucrose were elevated to a degree similar to that observed when pure fructose–sweetened beverages were consumed (19). Therefore, it is uncertain whether the adverse effects of sucrose and HFCS consumption are “diluted” by their lower fructose content relative to pure fructose. Additional studies are needed to compare the long-term effects of consuming HFCS and/or sucrose with 100% fructose.
