I have every sympathy with people who are not able to enjoy certain foods because of allergies or medical conditions.
I also have no problem with others who avoid particular products out of a lifestyle choice.
What concerns me, however, is that some of the medical reasons are based on supposition and many of the lifestyle reasons are based on misinformation.
For example, I read recently that gluten-free products typically contain far more fat and less protein than those they are seeking to replace.
A study comparing 654 gluten-free samples with their regular equivalents concluded they are an obesity risk after finding “significantly higher” fat levels and up to two thirds less protein.
Elsewhere, I learned that natural whole milk contains 8 times more protein than some plant-based milks.
Our diets and choices would definitely be better served if substitutes were either comparable or at least transparent about key differences.
