The standard American diet, also known as SAD, has been linked to the state of your gut (the digestive system), which is critical for ensuring good health. According to a recent report by CNN, 100 trillion bacteria live in our gut. These bacteria protect us from dangerous strains and help us digest foods properly. However, if our “good” bacteria, known as probiotics, are damaged through antibiotics or a poor diet, harmful bacteria can take over. To encourage the growth of good bacteria, a person should consume plenty of probiotics, eat a healthy diet with whole grains, vegetables, and less fat, and reduce stress.
