Awareness about food choices is more than a right for everyone. It is necessary for our nutrition and health--as a responsibility to fulfill since we are 'almost perfectly' liable for the fate of our own temples. Truly, we never wished to get fooled on what we eat; we always have to assure food security and safety.
Meanwhile, our food manufacturers partake on the legalities pertaining to synthesis of food supplies. It is their pride, for one, and a relevant determinant of assuring their products' quality. We must observe whether they are complying with integrity or not. These makers must show their compliance through various media. Moreover, part of which is product labelling. Aside from flaunting their marketing schemes in their packaging, they must put into label their products' nutritional level, as well as which regulatory boards--catering to certain social groups (i.e. religions)-approved such.
If ever things are not that clear to you then there is an example for you.
Look at this Nutella. Puzzling at a glance, right?
It shows the same mark. Man, is it a bad or threatening thing? Does that poses a health warning?
Remember, this is the last time you will be innocent about it. Actually, this mark symbolizes some approval from a certain food regulatory group.
This mark stands for products eligible for being a Kosher food.
Kosher is the Hebrew translation for "appropriate" or "fit". This kind of approval has a religious basis, specifically from the Hebrew bible.
For more than 3,000 years, Jews subscribe to this kind of diet. Certified kosher are blessed with better food quality, less prone to microorganisms and parasites.
Following the traditional classification of Kosher food, the food product known as ideal was stated in Genesis 1:29 of the Jewish Bible, and it is only vegetables.
Aside from vegetables, some animals and their edible products have become allowed (as time passes by) as Kosher foods: antelopes, gazelle, oxen, sheep, goats, mountain sheep, deer, wild goats, roebuck, and ibex. Specifically, these animals "chew the cud and have cloven hooves" (Leviticus, Chapter 11).
However, animal meat products should be separated from milk products. Materials used in preparing-to-consumption procedures of dairy and meat Kosher products should always be different.
Only acceptable slaughtering procedure should comply to the Jewish Law. Initially eligible animal who committed mortality through natural death or improper 'killing' will not be allowed to be consumed.
Other appropriate processes, area of preparation, and other certification methods are imperative for awarding 'Kosher food' status to a certain candidate.
