Abstract
Fast foods can be defined as convenience food purchased in selfservice
or carry-out eating venues without wait service (Pereira et al.,
2005).
Fast foods are quick, reasonably priced, and readily available
alternatives to home cooking. While convenient and economical for a
busy lifestyle, fast foods are typically high in calories, fat, saturated fat,
sugar, and salt (Jeffery et al., 2006).
When considering the relation between fast foods consumption and
diseases, it is important to consider if fast foods consumption are causal
to diseases or merely a proxy for other unhealthy lifestyle factors as many
studies suggest that such behaviors tend to cluster (Malik et al., 2006).
Expanding fast foods industry have caused many to posit a
potential link between the rapid increase in obesity, hypertension,
cardiovascular disease, diabetes, depression, infertility, and breast,
endometrial, colon, and prostate cancers prevalence and fast foods, in
addition to causing great public health concern. While speculation
abounds, few large epidemiological studies have been conducted in order
to prove this potentially deleterious association (Pereira et al., 2005).
There are many kinds of fast foods. We will be exposed to
hamburger and falafel as examples of the most popular fast foods in the
Egyptian street.
