For hilly/mountainous 20 mile/day 7-14 day treks, how much ground flax seed would you recommend each day?

I could've sworn I already answered this question.

Hmmm... I must have missed that answer. I was going to take a shot and say it depends on how many gold finches you have with you

Seriously, I love flax seed. "Uncle Sam Cereal" was one of my favorites when I was growing up. But the answer lies in your normal serving size and how many servings you think you'll consume.

I still tend to carry more food than I consume. I've gotten better at carrying lighter food, and even fewer servings, since I found the great tips and advice here, but I still carry food back with me every time and usually enough for at least a couple days if I needed to stretch it.

I'm not recommending that you do that too. I'm just saying that this is a difficult question to answer because it's really a personal preference. Some people tend to eat more when they're backpacking. I've found I actually eat less for the first few days and I seldom stay out longer than a few days.

As a rule, I bring normal portions for each meal and toss in a little extra in case I decide I need to stay a little longer.

And, I bring spare food with me in case I run across someone who needs it. This has actually happened to me several times. The first time it happened I had to cut my trip short because I ran into three young men who were famished after being out in a wilderness area for three days. I only brought enough for lunch, dinner, and breakfast. They were literally begging me for food and I could tell they were thinking about how good I might taste if they put me on a spit over a hot fire if I said no. It was actually a lot of fun to share the food and listen to their story. And they were truly thankful I shared what I had.

I'm not sure flax seed would have kept me off that spit though, so now I always toss in a few extra granola bars, just in case

I figured it out. I answered this exact question on another forum.

Thank you for your input.
I haven't found that info either. I was thinking that there would be a general recommended daily amount. Does something like that exist?

TMI ALERT

If you're taking it for the fiber, you only need to take enough to have stool that's neither too dry or moist. Generally it should pass all in one shot, it should be easy to evacuate with a bare minimum amount of pushing, be somewhat soft, and be very easy to clean up after with no sticky residue. It may also smell like burnt asphalt when you first start adding fiber to your diet. If you look at it for some reason, it should look like the surface is somewhat shredded. This is healthy, and is exactly what you want when you do your business in the woods.
