A diet poor in nutrition jeopardises your health. It increases your risk of conditions such as Type 2 diabetes, heart disease, high cholesterol, obesity, high blood pressure, osteoporosis and cancer.


Poor nutrition also affects your thinking processes and the way that your body functions generally. It can result in increased body fat, slower mental problem solving, lower core strength, slower muscle response time and decreased alertness.


Poor nutrition is also the leading contributor to the development of gout. This is a painful condition of the joints that can result in permanent damage. It is caused by an accumulation of uric acid.

Other Ailments

Aside from chronic diseases, other ailments like depression, eating disorders, stress and fatigue are often associated with poor nutrition.

Furthermore, a poor diet can impair a child's neural development, which leads to a lower IQ.
