Remove from your diet all types of cabbage (broccoli can be left) and oat dishes or oat elements, because the production of thyroid hormones is impaired. Thanks to such products, as in the previous point, metabolism slows down.
It is necessary to increase the intake of iodine in the body so that the thyroid hormones are well produced, there is no deficiency. Iodine in your body will be replenished by permitted seafood and greens with vegetables. Radish and daikon with horseradish will increase the production of thyroid hormones. And it is best to make juices from these products and mix them 1 to 1 with carrot juice.
Red meat and liver of any animal also promote good metabolism and increase the metabolic rate. Combine meals with regular exercise.
If you are concerned about poor blood clotting, you should eat foods that contain vitamin K. Vitamin K is found in liver, salads, meat, cod liver oil, eggs, seaweed, and greens.
