Fruit Sugar

Hi, I am trying to cut down meat not for a health point of view but for other reasons

Carbohydrate

Surge has dextrose (synonymous with glucose) as its sole carbohydrate source, while chocolate milk has an even mix of sucrose (in the form of either sucrose or high-fructose corn syrup) and lactose. While it’s common to assume that dextrose is superior to sucrose for postexercise glycogen resynthesis, research doesn’t necessarily agree. A trial by Bowtell et al showed a glucose polymer to synthesize more glycogen by the 2-hr mark postworkout [14]. However, two other trials whose postexercise observation periods were 4 and 6 hours respectively saw no significant difference in glycogen storage between sucrose and glucose [15,16].

Perhaps the most overlooked advantage of a fructose-containing carbohydrate source (sucrose is 50% fructose) is that it supports liver glycogen better than a glucose-only source, as in the case of Surge. A little-known fact is that hepatic glycogenolysis (liver glycogen use) occurs to a significant degree during exercise, and the magnitude of glycogenolysis is intensity-dependent [17]. Illustrating the potential superiority of sucrose over glucose, Casey et al saw no difference in muscle glycogen resynthesis 4 hrs postexercise [15]. However, there was more liver glycogen resynthesis in the sucrose group, and this correlated with a slightly greater exercise capacity.

One of the potential concerns of consuming a large amount of sucrose instead of glucose is how the 50% fructose content in sucrose might be metabolized from a lipogenic standpoint. Answering this question directly, McDevitt saw no difference in de novo lipogenesis (conversion to fat) between the massive overfeeding of either glucose or sucrose at 135g above maintenance needs [18]. Another potential concern is the use of high-fructose corn syrup (HFCS) in chocolate milk. The common fear of HFCS being some sort of special agent that undermines health is simply not grounded in science. HFCS is virtually identical to sucrose both in chemical structure and metabolic effect [19]. Independent researcher John White eloquently clarified HFCS misconceptions in a recent review, which I’ll quote [20].

“Although examples of pure fructose causing metabolic upset at high concentrations abound, especially when fed as the sole carbohydrate source, there is no evidence that the common fructose-glucose sweeteners do the same. Thus, studies using extreme carbohydrate diets may be useful for probing biochemical pathways, but they have no relevance to the human diet or to current consumption. I conclude that the HFCS-obesity hypothesis is supported neither in the United States nor worldwide.”

Sarcasm is a great thing! Acg67's posts typically have it!

I will point out that fruit sugar (aka fructose) IS processed differently. However, the evidence that it is going to make you fatter is not really there. Here is a good summary from an interesting article:

I have found it much more useful to check the Glycemic load of foods and beverages than going strictly by sugar grams here at MFP. Proteins, fiber and fats help to balance the rate insulin releases into your bloodstream.

Minimizing insulin spikes throughout your life can aid in type 2 diabetes prevention later in life. Most whole fruits and most vegetables are just fine GL wise, so no need to heavily restrict those items.

Juices and dried fruits are concentrated, and should be limited. Example to make 12 ounces of orange juice it takes 6 medium oranges. That is a ton of sugar, and you have removed almost all of the fiber. Not many people could or would eat 6 oranges in a sitting, but its easy to drink.
