Riboflavin – Vitamin B2

Riboflavin (also known as vitamin B2):

Riboflavin, vitamin B2, food sources and possible symptoms of deficiency.

Deficiencies of other B vitamins can cause a deficiency of riboflavin and vice versa. Riboflavin is involved in the metabolism of vitamin B6, niacin, folic acid and iron.  Riboflavin is also needed for metabolism of drugs and toxins and is essential for releasing energy from food.

Alcoholics, anorexics, and people low in other B vitamins are at risk of deficiency but otherwise deficiency is rare.  Riboflavin is in many foods.

Deficiency symptoms may include decreased red blood cell count with normal sized red blood cells; sore throat; magenta/red inflamed tongue, mouth, and throat; sore cracks at the sides of the mouth; and skin rashes.  Deficiency may increase risk of pre-eclampsia and age related cataracts.  Supplemental riboflavin was found helpful for preventing migraines.

Food Sources of Riboflavin (B2) include:

Fortified flour & cereal, whole grains, meats, fish, milk, eggs, meat, fish, beans, nuts, and seeds, nutritional yeast flakes, asparagus, broccoli, yellow summer squash, spinach.

Risks of overdose for water soluble B vitamins and vitamin C are rare:

B vitamins and vitamin C are water soluble, so overdose is rare.  Deficiency is more common because the nutrients are not stored like the fat soluble nutrients:  A, D, E, and K; and water soluble vitamins are not conserved by the kidneys like the electrolyte minerals:  calcium, sodium, magnesium, and potassium.

Riboflavin is a bright yellow nutrient and when taking higher doses in supplements may cause a bright yellow colored urine – it is non-toxic and would be less noticeable, a paler shade of yellow, when plenty of water is also being drunk throughout the day. Any time dehydration is present the color of the urine will be a darker shade and is a good reminder to try to drink plenty of water – 6-10 glasses roughly depending on body size, and amount of exercise performed and the level of heat or humidity in the environment.

Thinking about art and clean air

For an Easter treat I went to an art museum and after seeing three floors of great artwork from around the world and across time, I was exhausted.

My long time favorite was right outside near where I parked – Easter was a good day to find a good parking spot. The Thinker, a sculpture by Auguste Rodin, has always had a lot to ponder:

There were many exquisite works of art and beautiful household furnishings, costumes and painfully thought provoking works of modern art or photography. Flash photography was not allowed and standing too close to the images for photography was not allowed as the camera still makes a small flash of light even without the flash. The museum lighting was dim to help protect the works of art and these images have been photo edited to increase the light level.

The most meaningful work of art for the sake of our shared future and children’s future was among the photographs. My shadow and reflections of other artworks are captured on the tranquil looking image – of smog. “Unhealthy Air for Sensitive People,” San Fernando Valley, 1984, by Victor Landweber:

“Unhealthy Air for Sensitive People,” San Fernando Valley, 1984, Chronographic Print, – Victor Landweber, American Born, 1943 “…While appealing, the work documents smog in Los Angeles, a problem arising from the approximately four million people that call the city home.”

Some works of art had an inner glow – stained glass windows with a religious theme from 1890 by John La Farge, American artist (1835-1910), (dia.org, link for more information):

 

The architecture of the building and gift shop featuring original works of art by local and international artists are well worth a visit for their own sake.

It was a beautiful and thought provoking visit to The Detroit Institute of Art – what legacy do we want to leave the future to think about? Clean air? Faith and Hope? Beautiful architecture and flowers? Or smog?

It is a lot to think about.

The Thinker, by August Rodin, at The Detroit Institute of Art. Detroit, Michigan.
