Black coffee in particular is more acidic than your regular joe. You’re cool with it, so it’s possible that your body can manage the amount of acid you consume from your coffee. Since you experienced trouble after adding milk, your reflux may have a specific dietary link to fatty whole milk. Another possibility is you might be lactose intolerant or has a mild milk allergy. Lactose intolarence occurs when you lack the enzyme lactase to metabolize lactose (milk sugar). When this happens, the lactose will move right into your bacteria infested large intestine. The interaction with bacteria and the undigested lactose will cause bloating, gas, and diarrhea. A study published in 2011 involving 81 participants arrived to the conclusion that linked milk allergy and gastroesophageal reflux disease (GERD). What about the sugar? Generally, this sweet fella won’t affect your acid reflux, unless it is mixed with trigger foods.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel replyConnect with: Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
