In modern times, in plenty of countries fast food becoming cheaper and more widely available. I think, in the situation disadvantages of this outweigh the advantages, because fast food have lack of vitamins and protein, while have plenty of fats, because burgers made on a fat. However, these food can help when parents do not have enough money to more beneficial foods.
Often, the burgers made on the fat and do not have enough vitamins for ordinary human. Moreover, if a person is often eat fast food that lead to problem with heart, a percent of fat and a skin condition. For instance, majority proportion of people from USA have a problem with heart, because in the food plenty of a fat and the fat harmful for a heart and after 5-10 years eat fast food the heart can reject and lead to died of the person. Also, in the food people do not gain normal of protein and their muscles do not have enough protein to good work. That lead to issue with physical work, the person cannot lift a big weight after particular time.
On the other side, for a poor family fast food can become the best way, because fast food costs smaller than cost of other products. For instance, cost of a chicken with vegetables around 15-20 dollars, while cost of fast food around 7-10 dollars to combo in MacDonalds. Out of for people in the poor family are better buy fast food than the chicken with vegetables. For instance, the fast food helped for my sibling when she does not have a money for good foods and ate only fast food.
To conclude, fast food have a lack of vitamins and protein, but fast food one of the best way for the poor family. However, with lower price people do not wait a perfect quality of the food.
