Fast food does not often contain many food groups, including vegetables, fruits and whole grains. Food is cooked in highly saturated oil, and the oil is reused, creating a breeding ground for bacteria.
Most fast foods are fried or contain high levels of grease and oil, increasing the risk for heart disease. Since many have sedentary lifestyles, those who eat high-fat meals gain weight, increasing the workload on their heart.
Many ingredients used in fast-food meals contain contaminants including fecal matter; slaughterhouses are overloaded with animals, increasing the chances of contamination.
Some health issues about fast food include the obesity-related diseases associated with weight gain. Type 2 diabetes, sleep apnea, polycystic ovary syndrome, heart disease and dyslipidemia are just some of the ailments associated with fast food and obesity.
