It is easier to opt for ready meals, but they could be hazardous to your health. In general, prepackaged meals are preserved with too much sodium and are very high in calorie content. Some have as much as 1,800 mg. The extra salt will cause the body to retain water, leaving you bloated, at the very least.
Also, these meals contain fake vitamins and minerals, because processing food means that all the original nutrients get stripped out. Read the labels carefully and you’ll probably find lots of unhealthy ingredients which lengthen the shelf life but not yours.
