Cold feet and hands can be caused by a lack of iodine. Good sources of iodine are:
– marine algae (incredibly rich in iodine – 700 milligrams per 100 grams)
– soybean
– smoked herring
– seafood and shellfish
– garlic
– dried fruit and legumes
– Reduce your intake of acidic fruit, especially in the morning.
– Do some breathing exercises one hour before meals, morning, noon and night.
