Coca-Cola is the most popular carbonated drink. It has a fairly short ingredients label, but unfortunately that doesn’t prove to work in its favour. Coca-Cola contains Phosphoric acid (E338) - is used to acidify foods and beve..., which has a negative influence on our body’s ability to absorb calcium and magnesium. Besides, just this small bottle contains over eight teaspoons of sugar. It’s okay to have Coca-Cola from time to time, but drinking it frequently is bad for your health and body down the line.
