Cake is a Made-up Drug
The company to whom the canteen at work is subcontracted like to put promotional material on the tables, in an attempt to encourage people to spend more money there - eg, they push "healthy options" where, to get a good sized meal, you'd have to spend more money.
Anyway, this month they're pushing "Healthy Booster Cakes" which are "freshly prepared healthy afternoon cakes, packed with healthy ingredients to help give you energy, and boost your immune system." The energy bit is obvious - they contain sugar and fat. I do wonder how they "boost" the immune system though, what the active ingredient is, and whether they have any actual evidence that the ingredient works when dispensed in cake form.
And if their cakey drug delivery mechanism does work, I suggest that they patent it, get the hell out of the cut-throat sub-contracted catering industry, and make a huge great big pile of money in the pharmaceutical industry.
