Vitamin B1 deficiency causes beriberi in humans and animals (fatigue,muscle weakness,problems with gait and vision).A balanced diet helps prevent this disease. But vitamin B1 is also an important substance in the prevention and treatment of nervous degenerative diseases or some heart diseases, among other things.
Thiamine was the first vitamin to be discovered. Beriberi was known among rice eaters in China 2600 BC, but it was only in 1885 that its nutritional origin was proven and not until 1910 was thiamine identified. Thiamine deficiency causes the disease. This vital amine – given the name “vitamin” – is soluble in water and concentrated in the heart, the kidneys, the liver and the brain.
Thiamine is an essential substance involved in many complex biochemical reactions that help generate energy for the cell. But it is above all indispensable to the functioning of the nervous system, where its role is in the synthesis of the neurotransmitter acetylcholine, which transmits sensory impulses from one neuron to the other.
Yeast and wheat germs have the highest vitamin B1 content, but it is also found in meat, bran and cereals.
