While weight gain can indicate the need to rethink your lifestyle choices, many other health problems have roots in poor dietary habits. Here are a few:

• Premature aging: wrinkles are often associated with aging, however, they can occur during young adulthood as a result of a diet lacking in antioxidants as well as vitamins A, C, D, and E.
• Mental exhaustion: poor memory and loss of concentration can develop due to a lack of consumption of foods rich in omega-3 fatty acids such as fatty fish, nuts, and dairy products.
• Falling sick often: inadequate diet reduces the functional capacity of the immune system, making the body more vulnerable to infection from germs and contracting infectious diseases.
