A low-sulfur diet is a diet with reduced sulfur content. Important dietary sources of sulfur and sulfur containing compounds may be classified as essential mineral (e.g. elemental sulfur), essential amino acid and semi-essential amino acid (e.g. cysteine). Sulfur is an essential dietary mineral primarily because amino acids contain it.
Sulfites used in food processing (but not as a preservative) are required to be listed if they are not incidental additives (21 CFR 101.100(a)(3)), and if there are more than 10 ppm in the finished product (21 CFR 101.100(a)(4)) On July 8, 1986, sodium bisulfite (and other sulfites : "The chemicals affected by the order are sulfur dioxide ...
Sulfites that are allowed to be added in food in the US are sulfur dioxide, sodium sulfite, sodium bisulfite, potassium bisulfite, sodium metabisulfite, and potassium metabisulfite. [32] Products likely to contain sulfites at less than 10 ppm (fruits and alcoholic beverages) do not require ingredients labels, and the presence of sulfites ...
Some promoters suggest that most people do not consume enough sulfur. There is no Dietary Reference Intake (DRI) or Daily Value established for sulfur, but it is present in significant amounts in foods such as cruciferous vegetables, garlic, onions, asafoetida, legumes, nuts, seeds, plant milk, animal milk and eggs (both whites and yolks).

From the sulfide they form the amino acids cysteine and methionine, sulfolipids, and other sulfur compounds. Animals obtain sulfur from cysteine and methionine in the protein that they consume. Sulfur is the third most abundant mineral element in the body. [21] The amino acids cysteine and methionine are used by the body to make glutathione.
The content of these sulfur-containing secondary compounds strongly depends on stage of development of the plant, temperature, water availability and the level of nitrogen and sulfur nutrition. In onion bulbs their content may account for up to 80% of the organic sulfur fraction. Less is known about the content of secondary sulfur compounds in ...
The non-sugar content includes many salts, including calcium, potassium, magnesium, oxalate and chloride. It also contains sulfur, betaine, and the trisaccharide raffinose. These result from the concentration of the original plant material or other chemicals in processing and are unpalatable to humans.
Organosulfur chemistry is the study of the properties and synthesis of organosulfur compounds, which are organic compounds that contain sulfur. [1] They are often associated with foul odors, but many of the sweetest compounds known are organosulfur derivatives, e.g., saccharin.
