Riboflavin is destroyed by light and irradiation, but not by cooking. This is of particular interest now, because the government is considering irradiating all fresh produce to kill germs.
In general, people who live in developed countries like the USA get enough riboflavin. However, those suffering from eating disorders or living in poverty may not eat enough food to get sufficient riboflavin in their diet.
If you are a vegan or you are lactose-intolerant and do not eat dairy products, you should eat more dark, leafy vegetables and whole or enriched grain products.
--Caveat: Alcoholics are at particular risk for riboflavin deficiency, since alcohol inhibits the ability of the body to absorb and use riboflavin. This means that even if an alcoholic is eating lots of dairy products, the body may not have access to enough riboflavin to maintain good health. If alcohol is replacing food in the diet, there could also be a riboflavin deficiency.
If you eat a variety of foods from all of the food groups, you will more than likely get enough riboflavin.
Athletes and heavy laborers need a slightly higher amount of riboflavin in their diet, since these activities can deplete riboflavin. There is also some evidence that riboflavin may by useful in the treatment of migraine headaches.
