Preserved egg lean porridge is loved by the elderly because of its thick texture, smooth taste and easy digestion, but the elderly can't eat preserved egg lean porridge often.
Preserved eggs are alkaline, which can increase the viscosity of rice porridge, so the cooked porridge is thicker, but at the same time these alkaline substances will also cause a large loss of vitamin B 1 in rice and lean meat. Vitamin B 1 itself is not easily decomposed by heat, but it becomes very sensitive to heat when it meets alkali. Cooking porridge for a long time and high temperature is enough to degrade most vitamin B 1 in rice and lean meat. Especially rice and wheat are still the main sources of vitamin B 1 in China. If you keep eating preserved egg lean meat porridge, the human body will certainly not get enough vitamin B 1. Lack of vitamin B 1 can make people feel easily tired, headache, loss of appetite, constipation and so on. Therefore, the elderly should not often eat preserved egg lean meat porridge.
