We had to have a closer look at a daily meal. We were given the task to calculate the energy of the prepared food and to show it in the following three units of measurement: kilokalories (kcal), kilojoules (kJ) and kilowatthours (kWh).
On Monday I prepared "Tortillas" for lunch. The kids love this dish, because they can choose from various ingredients.
Calculation for one single Tortilla filled with chicken, salad, corn, cheese and sour cream:
290 Kalories (kcal) --> 1214.172 kilojoules (kJ) --> 0.33727 kilowatthours (kWh)
To calculate these three units I used an online calculator. Klick here to find out.

Genetically modified organisms are scary. Especially when they appear in food. Many consumers are worried about their health. But does not genetic engineering also have its good side? For example, when it comes to eliminating diseases from plants?

Food waste is thrown-away food, because it no longer looked good or because it couldn't no longer be sold.
In the "Duden" the word "waste" is described like this: "an act or instance of using or expending something carelessly, extravagantly, or to no purpose."
Nowadays we have to rethink our eating habits and the way we deal with our food. It shouldn't be careless.
Good examples:

"Äss-Bar"-Project, Zürich
"Falling Fruit"-Project
"Grassrooted"-Project, Zürich

There are more than 500 energy drink products on the market, and their increased popularity is matched by a significant rise in energy drink-associated emergency department visits and deaths.
“The energy drink industry claims that their products are safe because they have no more caffeine than a premium coffee house coffee,” said Dr. Jennifer L. Harris from University of Connecticut’s Rudd Center.
