In the bay area, people strongly believe in eating healthy especially while doing strenuous activity, like for example trekking. But Nepali guides and porters can’t afford the food prices paid by tourists trekking and therefore there is an unspoken rule that they all get free food. The catch is they have to eat whatever food their given, mostly potatoes and rice. Yet the natives are always the fastest up the hills and never in need of breaks or rest. Look at other non-Nepali survival stories like Seven Years in Tibet‘s Heinrich Harrer, he crossed 6,000 m Himalayan passes on more or less an empty stomach. So next time your complaining about food and trekking, remember Harrer and others who did so much more with so much less.
