i was able to jump on a listing in the GSF for Ray Jardine's "Beyond Backpacking" book and have been enjoying the read for the most part. i stumbled over what i think are some segments of junk science in the food section. Ray claims that his coffee drinking was a net loss due to the diuretic properties of caffeine. he also commented on the fuel savings from omitting the morning coffee ritual.
unless Ray was drinking 5 or more cups in a row, the coffee is hydrating, regardless of the caffeine. as for the fuel budgeting, my fuel is budgeted for my daily needs, and if a cup of coffee in the morning is one of my enjoyments, then i will carry the fuel.
he takes his diuretic case to drinking alcohol. in the quantities required to dehydrate, they simply wouldn't be fun to carry. a few beers or several drams of whisky isn't going to dehydrate a person. these ideas were proved incorrect long before 2001, when this edition was published.
the junk science continues in the section on water, apparently, only pure water will hydrate regardless of the amount of liquids one drinks. i guess Ray never realized we get plenty of water from the food we eat, even on the trail.
for the record, i rarely drink coffee, but when i do, i enjoy it. i do enjoy a tasty malt beverage from time to time, and esp. after a big mile day. nothing soothes the weary body like an English Bitters.
i've noticed some other very bizarre opinionations in this tome and i have to wonder what the point of backpacking is for Ray - he seems to garner little joy from many of the traditional notions of backpacking. big miles can be done along a lonely mountain road much faster, as that appears to be the motivation at times for the weigh considerations.
