Compare and contrast - Essay ExampleSome studies have argued that the nutritional tax of both fresh and frozen fodder is the comparable, and in some cases, can be higher for frozen/ keep foods. This is exactly what has been suggested by a question conducted in 1997 by the concerned department in one of the American universities. Furthermore, research has concluded that preserve pumpkins whitethorn provide 540% of Vitamin A versus 26% for the same amount of fresh pumpkins (Squires, 1997). Similarly, canned poultry and fish, which are high in protein content, remain unaffected by heat and, therefore, possess the same nutritional look upon as that of their fresh counterparts. In fact, the canning figure out ensures higher calcium content in canned poultry and fish than otherwise. On the other hand, differences in nutritional value between fresh and canned produce have been observed. This is because of the time at which the food is picked. Fresh food (including fruits and vegetabl es) contains highest nutritional value when purchased in season. food market stores often indulge in the practice of picking fresh produce before it is fully ripe. On the contrary, food picked for canning is often fully ripe. Thereafter, the heating process during the canning process destroys the vitamins resulting is lower nutritional value (Rinzler, 2011).

This is true, to some extent, because canned food be groceries more to purchase compared to fresh foods (Price, 2012).

Furthermore, the higher costs of canned food reflect the added convenience that people purchase when they pay a higher price for such food. Canned food can technically be bought at any grocery store or supermarket and may be ready to consume, requiring no precedent preparations. The lower costs of fresh food are attributed to the lower convenience attached to such food as fresh food, including fruits and vegetables, may have to be cleaned, washed or prepared prior to consuming it. Owing to the convenience (no prior preparation required) offered by canned foods, it is no wonder that the working class has been drawn towards them in their busy routines (Strasser, McGovern, & Judt , 1998). On the contrary, there are sufficient reasons to suggest that fresh and organic food costs significantly more than canned food. The term organic has given a new meaning to what was previously known as fresh food. This label has increased the cost of the food possessing the label as organic produce, unlike canned and processed food, is usually free from harmful chemical fertilizers and pesticides (Ricke, Loo, & Johnson, 2012).
