Acidic Food
Our bellies are empty in the morning, and although you might think your stomach is always filled with gastric acid, it’s actually not. Our stomach releases the acid as needed, and there’s very little available early in the day.
Acidic food can cause irritation, gastritis, and, in general, digestive trouble because you’re taking your body off guard. If you’re not careful, you might even cause or worsen the development of ulcers.
