Vitamins Guide – VITAMIN B1
Vitamin B1-Rich Foods
Vitamin B1, also known as thiamin (or thiamine), is a water-soluble and essential nutrient that plays a crucial role in maintaining a healthy nervous system and converting food into energy. It is needed to transmit electrical messages in nerve and muscle cells like in the heart and for making red blood cells. In addition, it helps in amino acid synthesis and plays a role in digestion. It is also involved in moving glucose within cells and insulin production, so people with diabetes need it.
If you want to increase your intake of this critical vitamin, try incorporating the nine delicious and easy-to-make vitamin B1-rich foods covered at the end of this article into your diet. From breakfast to dinner, you’ll have a variety of tasty options.
The sad thing about thiamin (vitamin B1) is that it is readily lost from the body through the kidneys. As a result, most of us only have stores of this vitamin to last one month or so. Therefore, a regular dietary supply of vitamin B1-rich foods is essential. Typical food sources are:
Another way to lose vitamin B1 is via food processing, that is, mincing, chopping, liquidizing, preserving, and canning. Also, boiling foods pulls the thiamin content down 50 percent because the vitamin is so water-soluble. Also, adding baking powder and cooking food at high temperatures destroys the vitamin. Toasting bread removes a third of the thiamin content while freezing meats destroys half the thiamin. Finally, roasting meat at temperatures of 200°C lowers the vitamin’s content by a fifth. So, thiamin is quite a temperature-sensitive compound in vitamin B1-rich foods.
It Makes You Wonder
One wonders how it is possible to preserve the thiamin content of vitamin B1-rich foods. Well, there is supplementation if you must do the above things to foods that destroys the vitamin, but more about that later.
Benefits of Thiamin
Four vitamin B1 benefits have been identified to our well-being. By eating adequate levels of thiamin by consuming vitamin B1-rich foods, folks can take advantage of:
Vitamin B1 Deficiency
In countries where the staple diet is polished rice (as opposed to the more nutritious brown rice), vitamin B1 deficiency is common. This is because those people don’t have access to vitamin B1-rich foods. The vitamin b1 deficiency symptoms are extreme weakness and fatigue, otherwise known as ‘Beriberi.’
The disease called Beriberi is quite unpleasant, and victims experience difficulty walking and a loss of feeling in their hands and feet. Also, they have a loss of muscle function or paralysis of the lower legs, coupled with mental confusion.
Dry and Wet Beriberi
There are two forms of Beriberi: dry and wet. In the dry form, weakness, numbness, and pins and needles in the legs are typical symptoms. In the wet form, there is severe fluid retention. In people with thiamin deficiency and a high alcohol intake, there is the danger of getting Wernicke-Korsakoff Syndrome. If left untreated, it leads to irreversible dementia.
Guillain Barré Syndrome
The Beriberi symptoms, but not the mental problems, may be confused with Guillain Barré Syndrome (GBS), of which this scribe was a victim in 2010. I recall being prescribed vitamin B1 tablets by a young locum standing in for my regular, more experienced physician. The pills had no effect, but as soon as my regular doctor returned, he quickly diagnosed GBS, and before I knew it, I was in the hospital for five weeks. It took years, but I have more or less recovered. Nevertheless, it goes to show what a simple thing like not having enough vitamin B1-rich food can do to your health.
Vitamin B1 RDA
The recommended daily allowance of thiamin or the vitamin b1 dosage for adults is around 1 mg. In general, the more carbs eaten, the more thiamin is needed. Folks drinking too much coffee or tea have to be careful because these beverages destroy the vitamin. Stress quickly uses up available thiamin stores, too. Also, drinking too much alcohol interferes with vitamin B1 metabolism. All this shows that it is a good idea to keep eating vitamin B1-rich foods.
Excessive Thiamin Intake
On the whole, thiamin is relatively non-toxic because excess of the vitamin is quickly removed in the urine. However, over-supplementing with thiamin in high doses (5,000 mg of thiamin hydrochloride or more) may trigger headaches, insomnia, nausea, and fast heartbeat. Fortunately, these symptoms quickly go away once excessive supplementation ceases.
