The glycemic index (GI) is a measure of how quickly glucose appears in the bloodstream after eating a specific amount of a carbohydrate dense food.
Glycoalkaloids
Before we all go invest in potato crops, let’s not forget about glycoalkaloids (GAs). GAs are nitrogen-containing plant metabolites that help defend against pests, pathogens, and so on. When consumed to a point of toxicity, they disrupt cell membranes and inhibit neurotransmission.
Acrylamide, acrolein & lectins
Acrylamide and acrolein are also toxins to the body. Both are formed with heat treatment of certain foods, including potatoes.
Organic potatoes
Conventional potatoes may be sprayed with bud nip (chlorpropham) to prevent budding. Bud nip is also toxic when ingested.
