147 'Warm' foods and Warming foods The heat in hot foods and hot drinks is comforting, but the comfort is superficial and temporary— it's like warming your hands at a fire. But some foods are warmth-giving by nature: whether you take them hot or cold they will warm you all through. Chief among them are fats and oils, sugar and jam, bread, flour, cereals, potatoes, cheese. These help to generate energy by supplying the engine of the body with fuel to burn. So, when you're using the oven or hot-plate, always remember to cook a few extras, a few warmth-giving dishes, to eat cold.
