@gg12, some potential gut irritants include:
• Fiber
• Raw starch and any other poorly digested food, including eating and drinking too quickly
• Unripe fruit and even ripe fruit grown under harsh conditions as they produce defense chemicals/allergens
• Unrefined/unpurified salt and sugars, including honey, contain potential allergens
• Additives such as cultures, enzymes, gums, citric acid, ascorbic acid, propylene glycol and polysorbate 80
• Supplements may contain potentially allergenic byproducts from the manufacturing process
•Stress, including stressful thoughts, can affect gut permeability per Ray
