Does Herbal Tea Break A Fast – Further Details
Herbal tea is an infusion or blend of various leaves, fruits, bark, roots, or flowers. For the most part, herbal tea is considered to be fasting-friendly. I say “for the most part” because every person is unique. You will need to drink herbal tea during your fast to see how your body responds.
Herbal tea tends to fall into the “grey area” of clean fasting. For some people, it’s fine to drink and for others, it’s not.
Some people may notice that their insulin levels do spike while consuming herbal tea. Others may feel fine drinking herbal tea while fasting. Do an experiment and see what works best for you.
Generally, herbal tea is more bitter, so it should not trigger an insulin response. As a reminder, you should not add any sweeteners or milk to your tea while you are fasting. If you enjoy adding these items to your tea, drink your tea during your eating window.
Sometimes herbal teas are packed with fruit. Fruitier herbal teas may contain more sugar and could spike your insulin levels, therefore breaking your fast.
Intermittent fasting expert Gin Stephens says, “the fasting time isn’t supposed to be a flavor adventure.”
If you have an herbal tea that is sweet, fruity, and contains a lot of flavor, it may not be a good choice for your fasting window.
