Beri-beri is a disease caused by a deficiency of vitamin B1 (thiamine) in the body.
Insufficient intake of this vitamin can lead to serious problems with the nervous system, heart, and digestive system.
When following a keto diet, it is important to pay attention to the intake of vitamin B1 to avoid the development of beri-beri and maintain the health of the nervous system in optimal condition.
Symptoms. Symptoms of the dry form include muscle weakness, loss of sensitivity, and coordination problems, while the wet form may cause swelling and heart issues.
Beri-beri can lead to polyneuropathy, resulting in pain, numbness, and loss of muscle function.
Treatment of beri-beri. Treatment for thiamine deficiency typically involves taking vitamin B1 in supplement form and modifying the diet to increase the intake of foods rich in this vitamin.
Sources of vitamin B1 on a keto diet: nuts, seeds, pork, beef, and liver.
Interesting facts about beri-beri
Origin of the name. The name “beri-beri” comes from the Sinhalese word “beri,” which means “I cannot.” This relates to the symptoms of the disease that can lead to severe weakness and inability to move.
Types of beri-beri. There are two main forms of beri-beri: dry and wet. The dry form primarily affects the nervous system, while the wet form impacts the cardiovascular system.
Historical significance. Beri-beri was widespread among sailors in the 19th century, especially those who primarily consumed white rice, which is low in thiamine.
First description of the disease. The first medical description of beri-beri was made in 1690 by Dutch physician Willem Bicken, who noted the link between diet and disease among sailors.
Epidemic in Japan. In the late 19th century, there was a major epidemic of beri-beri in Japan caused by the population’s switch to processed white rice.
Prevalence of the disease. Beri-beri is now rarely seen in developed countries, but it can still occur in regions with high levels of poverty and malnutrition.
Alcoholism. Major risk factors for developing beri-beri include not only poor nutrition but also alcoholism, as alcohol interferes with the absorption of thiamine.
Hereditary factors. In some cases, beri-beri may be associated with hereditary conditions that affect thiamine metabolism.
Exacerbation of symptoms. Symptoms of beri-beri may worsen under stress or with increased physical exertion, as the body requires more thiamine during such times.
Global statistics. According to the World Health Organization, cases of beri-beri are still reported in some Asian countries, particularly among populations suffering from malnutrition.
