Although many people overfeed on packaged and convenience foods, they are undernourished due to the fact that these foods lack nutrients such as vitamins and minerals, which are essential for a healthy body, according to SFGate. To eliminate nutritional deficiencies, people should eat nutrient-rich whole foods such as fruits, lean meats and vegetables.

An increase in the availability of unhealthy and convenience foods leads to increases in adult and childhood obesity. The Centers for Disease Control and Prevention notes that obesity has risen to 17 percent among children and 35.7 percent adults, as SFGate reports. Obesity acts as a risk factor for serious health problems such as hypertension, heart disease, Type 2 diabetes, sleep apnea and liver disease.

Aside from obesity, Type 2 diabetes can also result from the unhealthy overconsumption of sugar-rich foods, which repeatedly raises and lowers an individual's blood glucose level, as SFGate explains. This unstable blood glucose levels can cause insulin resistance, which eventually develops into Type 2 diabetes.
