There is a great deal more potassium in plant-derived foods than in animal-derived ones. For ex ample, soybeans, pumpkins and bananas contain about 300 times as much potassium as sodium. Red meat, fish and poultry, on the other hand, contain only three to five times as much potassium as sodium. And cured foods such as ham actually contain more sodium than potassium.
而植物性食品的含鉀量明顯高過動物，以黃豆、南瓜、香蕉為例，鉀含量都是納的三百多倍；而雞鴨魚肉等動物性食品的鉀含量只有鈉的三到五倍，煙燻類食品如火腿中鉀的含量甚至低於鈉。
