Nutrition on the road - What, How and Why?

Here's the recipe:

It's not a tiny amount of delicious fatty protein, but the rice is by far the largest component. From that site:
Energy 225 kcal • Fat 8 g • Sodium 321 mg • Carbs 30 g • Fiber 1 g • Protein 9 g

I think these are meant to be a foil to sweet majority of energy foods.

Quite high in fat.

Fat in your gut slows down the absorption of carbohydrates which is not good for endurance performance.

Of course, cruising along to Dunwich, peeps might not give a shit about performance. They might still have indigestion, etc though.
