Paleo Diet and Paleolithic Diet Questions & Answers

Question

Hi all, my question concerns the ratio of glucose:fructose in foods. From what I've heard from some sources the OPTIMAL ratio for health is 1(1:1, Fructose:glucose). From what I've heard from others is the lower the fructose, the higher the glucose, the better. Would anyone sort out this contradictory information? I am thinking about creating a post-workout mixture of mased russet potatoes and molasses with sea salt added. What are your thoughts on this strange mash in light of the OPTIMAL ratio?

Eat fruit, it's already perfect, tastes great, and is refreshing. – Grok Jun 17 2011 at 7:42

some fruit Grok. plenty of it is worse than candybars. Ill restrict my comments to say: Keep your fructose intake low. Your liver can only process a certain amount a day regardless of ratio. – Stephen-Aegis Jul 15 2011 at 10:25

I consume no fruit and haven't since around the time of this post. Are there even any nutrients that fruit contains that can't be derived from other non-carb/fructose-rich sources? – PersonMan Jul 30 2011 at 16:00

Whoa whoa 1:1 is waaaaay too much fructose. That's table sugar. Ideally, you want 0 grams of fructose per day, but that's nor realistic, so keeping it under 10 is a good goal. Skip the molasses and just eat the potato.

	Thanks for advice. And I thought I was being 'healthy'--d'oh. That ratio came straight from the Layman's source Wikipedia too! – PersonMan Apr 21 2011 at 23:29
	Hey travis, would you have any recommendations for mainly glucose vegetables which are high carb(for my post workout mash)? – PersonMan Apr 22 2011 at 0:10
	Use sweet potatos if you can handle em. They have just glucose/and maltose I think? Taste better than white potatos IMO and have less glycemic index which is good. Put cinnamon on them with a tablespoon of virgin coconut oil mixed well to a light consistency and you got yourself something that tastes like a dessert but is healthy and will give you long lasting energy. – justanotherhunt Apr 22 2011 at 0:54
	I was looking for some higher g.i carbs for more rapid assimilation post-workout. Also, I heard that the G.I doesn't matter...does it?(I seem to be adhering to my old beliefs). – PersonMan Apr 22 2011 at 1:21
	white potatos, white rice and sweet potatos are all fine IMO. But I eat sweet potatos because for me white rice and white potatos make me hungry and crave more carbs. I am not sure why, sweet potatos don't do that to me so I believe they're better. Have you ever tried eating 1-2 tablespoons of virgin coconut oil post workout? That stuff is amazing for energy, and I even feel naturally euphoric and giddy. Works better than butter and other fats for energy IMO. And the other benefits are numerous. – justanotherhunt Apr 22 2011 at 2:10

Dr. Lustig suggests that fructose is poison. If you have 89 minutes, it's very interesting, if you can hang through the diagrams.

His name wouldn't be 'Victor' would it(a famous con-man)? I'll give it a shot. Any advice re: 'pure'(or max.pure)glucose carbs for after a workout(ideally starchy that would remain in the g.i tract for a short while). – PersonMan Apr 22 2011 at 1:22

OP is asking for food though, not isolated fructose. – Ikco Apr 22 2011 at 7:45

Did you watch the whole lecture? Lustig actually thinks that fruit is to be excepted from the "fructose is poison" rule, and says the same in the interviews he's given. From what I remember, he reasoning is the fibre content. – Katie Jul 30 2011 at 1:53

You're looking for yuca. Probably the highest GL but close to zero sugar and therefore zero fructose. It's one of the safest starches.

	I hear tell Cassava/Yuca causes Kwashiarkur in Africans with whom it is a staple. Do you say that it is highest glucose:fructose='GL'? What would YOU do with a Cassava plant? – PersonMan Apr 22 2011 at 4:14
	cassava chips at trader joes are really tasty – Jeff Apr 22 2011 at 5:48
	You're not eating nothing but yuca, right? Why would you get that when you seem to be a grown man eating some amounts of protein. I supposed u can get K if you eat nothing but yuca. But you want some filler, quick source of energy and glucose. That's what yuca is for. The negative is it will skyrocket your BG and that is not good for those w/leptin and insulin resistance. If ur healthy, however, nothing better after a workout than yuca, IMHO. – Namby Pamby Jun 17 2011 at 15:57
	Jeff, what are those cassava chips cooked in? Omega6 Industrial Seed Oils? – Stephen-Aegis Jul 15 2011 at 10:26

You want as low fructose as possible. Quick answer since I'm typing this on my iPhone: fructose goes straight to the liver plus while in the liver UP regulates the intake of glucose into the liver. So fructose alone is hard on the liver. Fructose on the presence of glucose is even worse.

I heard that glucose actually improves absorption of fructose. – manul Nov 9 at 12:23
