View Full Version : Dextrose vs Bananas/Fruit in PWO Shake

With my current diet, there are 0 servings of fruit.

I currently take a PWO with powerade, which gives all the sugar I need. (I doubt it's 50% dextrose, 50% maltodextrose?)

PWO
Protein from (2 servings of whey) = 40 g of protein
Carbs/Sugar from (3 scoops of powerade) = 60g of sugar/carbs

(I've read a recommended 2:1 ratio with carbs/protein, but predict I'd get excess fat along with muscle so I make it 1.75:1 instead)

I did some searching on this site and haven't found an real comparision or read anything about the fact that you're supposed to get 2-3 servings of fruit a day. (I currently have 0)

I have Vitamin C, in a small amount, but was wondering what the difference between drinking a combination of orange juice and eating bananas with a PWO shake vs having a PWO shake with dextrose.

I don't take creatine, but may begin taking it; only plan on taking 5 g a day max; before I workout. So, most of the creatine should be gone after the workout and won't combine with the orange juice into uric acid?

fruit is part of a healthy diet. myself and many others on here eat it but others dont because they are afraid of the sugars when cutting. it is fine to have some after working out but it does not substitute a pwo drink. fruit does not give you the insulin spike that dextrose and maltodextrin do. your body uses the sugars from dextrose and maltodextrin immediately creating an insulin spike. i dont remember the names of the sugars so correct me if i am wrong. fruit contains fructose which must be converted by the body to make glucose. bottom line - you want immediate glucose after working out and you get that from dextose/maltodextrin.

This I do know...

Fruit=Fructose...which your liver converts to glucose...hence it doesn't give you the immediate insulin spike because it needs to be converted first. (I have limited biology knowledge so anyone can correct me if I'm wrong)

I could always take a vit C pill...my dad was complaining that I was going to hurt myself by not getting enough vitamin C.

Fructose in itself is very low GI. I believe it is in the low 20's.

Fruit is a very important part of your diet and I think cutting it out of one's diet is a mistake. Sure there are some fruits with fairly high GI, but most are either on the cusp or right under the lower GI rating of 55. Melons and Tropical fruits tend to have the most impact on blood sugar, but the tropical fruits also provide the most health benefit. Kiwis, Mangos, and Papayas are some of the most nutrient dense food you can eat. Learn to fit them into your diet. Remember formulate diets so you can live this way instead of being totally extreme and losing interest b/c you have to cut out healthy foods like fruit. I personally could never give up apples, oranges, grapes, etc. and it didn't keep me from losing 2lbs a week over 20 weeks.

Balanced nutrition is important. I think most people want to lose weight, but they also should strive to be healthy. Learn to eat healthy foods and use pills as supplements, not replacements. Cutting out carbs, fat, or fruit is not the way to go about it. Balancing and moderation is key. For those making lifestyle changes then it will be easier down the road if you take on this philosophy.

fruit in your post-workout shake is a GREAT choice, if you choose high-glucorse:fructose ratio fruits like banana, grapes and pineapple, these will provide vitamins and minerals that are essential for recovery and growth, i really dont belive in taking in pure sugar for the largest carb hit of your day, what a waste of nutrients!

But how much longer does it take your body to convert the fructose into glucose?

Keeping in mind I want to prompt max muscle recovery right after working out. I did begin (and stopped) to drink a can of papaya juice seperate from my protein shake right after working out. Will I achieve greater results from dextrose?

I actually like the idea of eating fruit (I'm starting to think a cherry coke or orange soda would be just as fine) instead of just ordering a 10 lb bag of dextrose and mixing it in with my protein.

After typing this I found a great post that you can find at: http://forums.johnstonefitness.com/showthread.php?t=12001&highlight=dextrose

All and all, for the moment, I'm going to add fruit back into my diet, but in the morning instead of after my workout. Dextrose is cheaper than fruit anyway... :rolleyes:

I still think the question remains valid on fruit vs dextrose, I think you could sum up that fruit is an "ok" substitute, but using pure glucose (dextrose in this case) will be much quicker, thus much more effective at prompting muscle recovery.
