Refined cereals typically have 2 or fewer grams of fiber per serving, and one cup of a refined cereal, such as corn flakes, counts as 1 ounce of refined grains. Unlike whole wheat or whole grain pasta, refined pasta lacks much of the fiber and the B-complex vitamins found in the unprocessed version.ike bread, some forms of rice are considered to be refined grains. White rice and most of the quick-cook rices are refined and, as a result, do not contain an intact grain.
UVB, the chief cause of skin reddening and sunburn, tends to damage the skin's more superficial epidermal layers. It plays a key role in the development of skin cancer and a contributory role in tanning and photoaging. Its intensity varies by season, location, and time of day.
Most often, the emitted light has a lower energy (longer wavelength)than the absorbed light. So, most often any fluorescence we can see is produced by light withhigher energies (shorter wavelengths) than visible light. This shorter-wavelength light isultraviolet, the kind that causes sunburn.
