EPG is safe, unlike Olestra
Early in rebuttal, after ingredient listNorton clarifies that the fat substitute EPG remains solid at body temperature, preventing the anal leakage associated with Olestra, and thus is not a gastrointestinal threat at normal intakes.
Why this matters: Contrasts with the viral fear-mongering around fat substitutes; provides a physiological distinction that should reassure consumers.
Justin Mars compared EPG to Olestra, the infamous fat substitute that caused leakage because it was liquid at body temperature. Norton explains that EPG is chemically modified to be solid at both room and body temperature, so it passes through undigested without the same problems. At very high intakes there may be some reduction in absorption of fat-soluble vitamins, but amounts in the bar are far below that threshold.
Norton addresses the claim that EPG is 'designed to pass through your digestive system without being absorbed.' He says the issue with Olestra was its physical state—solid at room temp but liquid at body temp, causing leakage. EPG, however, is solid at body temperature, so it does not cause GI distress. He notes that there's some concern at 'very very high intakes' about reduced absorption of vitamin D and beta carotene, but you'd need to consume a lot. The takeaway: getting the mouthfeel of fat without the calories is a net positive, not a danger.
EPG is solid at room temperature and solid at body temperature. It is not going to cause leakage. It does not appear to cause gastrointestinal distress.
