Bring back pre 1960s wheat and all its by-products such as breads, rolls, crackers, cookies, biscuits, cakes, donuts, muffins, pancakes (which is an American breakfast staple), waffles, noodles, pie crusts, pasta, ice cream cones, pizza, and cereals.
No, I'm not singling out one and only one issue for the lack of that bodybuilding "vac" that many had back in the day, not to mention flat (as opposed) to distended stomachs that nearly all have today. Yes drugs (or rather the type of drugs) do play and are playing a huge role in what we are and are not seeing on that bodybuilding stage today. But still, nutrition is a big part of a bodybuilder's sport, and since carbs is one of the major (and with some
the major) consumed macronutrient, then given enough time, the results are evident of something not so right is (and has been) going on for some time now. Genetically modified wheat began (in Italy I believe back in 1959/60), and was slowly introduced to the whole world.
This may seem trivial, but we've discussed this before on Ausbb, the pullover exercise, which was extremely popular when the "vac" was also very much visible with most bodybuilders of yesteryear. Every little bit help; wheat, drugs, pullovers.....and so many other factors of course.
