Sweets
Yet another reason to avoid ultra-processed food when you can is that junk food like sweets and ready-made meals have the ability to boost your B.O. This is because the microbiome in our gut is relatively not great at processing high GI foods, causing some compounds to be excreted early through the skin. The only way to find out, of course, is to "eat clean" for a week and have a relative or friend give you a sniff each day.
