Nutrition on the road - What, How and Why?

... seems excessive

It's not excessive if you need x grams of protein, measured.

babies get all they need from milk alone and studies demonstrate that choccy milkshake is on a par with commercial recovery drinks

How are those breast milk smoothies working out for you?

Protein supplements are for bodybuilders, not cyclists.

If you're training you are 'body building'.

I can get a three tins of pilchards, or two of tuna, from my pound shop: no need for fish oil supplements either.

A bottle of cod liver oil tablets costs less than a quid. The quantity and quality of research into fish oils is massive and dates back to the 70s. It's not a fad diet. Most of the stuff I've read concludes even a very good western diet falls well short of the optimum amounts. The truth is your diet is more the product of culture and industry since ww2 than human evolution a diseased mind ;-)
