Does eating yogurt with a metal spoon kill the good bacteria?

Eating yogurt with a metal spoon does not kill the good bacteria present in it. The good bacteria in yogurt, such as Lactobacillus and Bifidobacterium, are resilient and can survive contact with metal.

The bacteria in yogurt are protected by a thick cell wall and a protective layer of mucus, making them resistant to damage from metal spoons or other utensils. Additionally, the acidity of yogurt itself helps preserve the bacteria.

While some studies have suggested that metal ions, such as iron or copper, can interfere with the growth of certain types of bacteria, the amounts present in a metal spoon are typically too small to have a significant impact on the bacteria in yogurt.

Therefore, you can enjoy yogurt with a metal spoon without worrying about killing the beneficial bacteria.
