Glucose, Electral and Spirulina
Instead of sugar, I use glucose to make my porridge. I don't have any specific reason for doing this, except that i find the small glucose packets more convenient than carrying sugar in paper bags.
Electral, while not technically a food item, needs a mention here because it is very important to carry rehydration salts with you while hiking. On long hot days it is easy to lose a lot of salts from your body, not to mention the constant risk of diarrhoea associated with drinking water from open streams far away from their source. So a few packs of rehydration salts is a must while trekking out in the mountains.
Spirulina deserves a mention as well. Because admit it, the food you eat on the trail can never substitute for the fresh food you eat at home. So it is essential to take some vitamin and mineral supplements on the trail and I prefer to take Spirulina tablets for this purpose. You can also find Spirulina powder in some health shops and use in your dishes, but I prefer to take the tablets directly.
