Users are calling for regulatory actions, such as banning carrageenan and reducing consumption of processed foods, indicating significant perceived impact.

Abstract in brief

  • Carrageenan (CGN) is a common food additive derived from red seaweeds, used for its thickening and stabilizing properties, but its safety has become a topic of concern due to its increased consumption in processed foods.
  • Research indicates that CGN can trigger immune responses, alter gut microbiota, and weaken the gut mucus barrier, potentially contributing to inflammatory bowel diseases (IBD), and is also linked to allergic reactions known as Gal syndrome.
  • Given the current lack of definitive safety data, the review recommends further research and suggests reducing intake of ultra-processed foods containing CGN to minimize potential health risks.

@jantunen_matti En näe karrageenin suihkekäytössä ongelmaa, mutta toisaalta en luota myöskään EFSAn arvioon turvallisesta saantimäärästä. Tutkimuksissa karrageenin saanti on yhdistetty erilaisiin ruuansulatuskanavan häiriöihin. @RiittaHanhisua2 https://t.co/kjpgsAdH0B

@RobertKennedyJr This paper seems to show that carrageenan triggers an immune response and may contribute to gut inflammation. It’s time for @HHSGov @US_FDA to prioritize public health and ban carrageenan from food products. https://t.co/PEP2oxfWE7

@AnitaN1007 @swillsm @AlboMP @Mark_Butler_MP @IndependentSage the carrageenan (CGN) worries me, bc some of the spray is bound to end up in the gut. CGN has been shown to cause inflammation, reduction in good bacteria & reduced mucus membrane. prob not nearly as risky as covid, i’d prefer an alt. saline or enovid? https://t.co/qlV5nepX8K

@Alpro You profess to sell healthy products but still put Carageenan in your products. Which, according to some scientists (who have wanted it banned since the 60's) is cancer causing, IBS and other diseases. Read this https://t.co/kMtebzD0H5 There are healthy alternatives!

Até que não haja dados sobre a segurança e os efeitos da #gomacarragena disponíveis, é aconselhável reduzir a exposição humana à #carragenina limitando alimentos ultraprocessados. #Carrageenan https://t.co/STy2pK97mA
