Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

Aspartame is about 180 to 200 times sweeter than sucrose (table sugar). Due to this property, even though aspartame produces roughly the same energy per gram when metabolized as sucrose does, 4 kcal (17 kJ), the quantity of aspartame needed to produce the same sweetness is so small that its caloric contribution is negligible.

All animals and fungi are chemoorganoheterotrophic, since they use organic substances both as chemical energy sources and as electron/hydrogen donors and carbon sources. Some eukaryotic microorganisms, however, are not limited to just one nutritional mode. For example, some algae live photoautotrophically in the light, but shift to ...
For example, if a 12-ounce can of soda contains around 200 mg of aspartame, and a person weighs 70 kilograms (154 pounds), the ADI would be 2800 milligrams of aspartame per day—or 14 cans of soda.

In the United States, six high-intensity sugar substitutes have been approved for use: aspartame, sucralose, neotame, acesulfame potassium (Ace-K), saccharin, and advantame. [3] Food additives must be approved by the FDA, [ 3 ] and sweeteners must be proven as safe via submission by a manufacturer of a GRAS document. [ 44 ]
Decades after aspartame was approved for use in the United States, the sweetener’s safety is getting another look by global health bodies assessing its potential links to cancer.
For all animals, some amino acids are essential (an animal cannot produce them internally) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early ...
