Are you looking for adjunct free beers? Or beers that don't use the "ingredients" listed in the notoriously uninformed food babe article
Adjuncts are part of the style
for American Lagers. Adjuncts like rice and corn are used to boost ABV while minimizing flavour contribution. As brewing scientists work to optimize the brewing process at these beer factories it makes sense that they use processed alternatives to get the same sugar content without the risk from varying agricultural crops. Some breweries even process the hops and extract the alpha acids (the bittering compound) to reduce the risk of skunking when the beer is on the shelves. Even if it is a flavourless product, American lagers are a brewing and engineering feat. Mass producing such a clean and flavourless product, with such consistency is very difficult to do and requires a very good brewing process.
It is very difficult to appreciate BMC beers as a craft beer fan, since there are many beers out there that have much more complex and enjoyable flavours, but once you start brewing you tend to gain an appreciation for what they are able to achieve, even if you don't enjoy drinking it.
There are many items used in brewing process that some may consider weird and bizarre, but many of them don't make it into the final product. Many are used in filtration, some are used in water treatment, some don't even make contact with the beer and are only used in the brewing equipment themselves.
In general I think many of the traditional german breweries still brew all-malt beers. Hofbrau, Weihenstephaner, Schneider, and many others brew great all-malt lagers.
