The Age of Aquarius is dawning (for real)!!

Short answer: unsure.

Long winded answer: I'm not sure if there are such measuring devices that are affordable for the average person. I've never looked. My guess is that apples register equally given they are mere cultivars of a single species that originated from the wild forests of Kazakhstan. Most sugars should be avoided altogether including natural fructose. Fruits are also acidic. When talking about high frequency super foods, the best known examples of produce just don't compete with certain herbs and fungi. Certain algae like astaxanthin are excellent as well. And then you have to consider how it was produced and the possible contaminants that could have tainted its potency. Preparation is also important in how certain herbs are harvested and crafted into whatever form they are sold as. In other words, optimal health covers myriad considerations but as a rule this frequency thing is more relevant on the species level than the cultivated variations from genetic tampering. There are always exceptions of course and i do not have the answer for apples.
