I totally agree with you about the highly processed foods filling our grocery store shelves.
But the problem with modern grains is that they have been genetically modified to the point that they are nothing like the grain of Biblical times. The closest modern grain to that is “Einkorn wheat”. Modern grains are literally poison to our bodies. You can get any carbs your body needs from vegetables, nuts and seeds, and you can make bread from seeds and nuts that would be very much like the flat unleavened bread eaten in Biblical times. Only a few people with hypothyroidism have to be cautious of not going too low with their carbs.
There are quite a few examples of peoples such as Inuit and Eskimo who pretty much lived on meat, fatty fish and animal fat with only occasional eggs, plants, seaweed or berries. On this diet they literally developed no heart disease, diabetes, tooth decay or cancer. Only when they adopted grains and sugar from trading with whites did they begin to suffer from these diseases.
Read “Wheat Belly” by cardiologist Dr. William Davis to learn more about this topic.
Read Wheat Belly a few years ago. Great book.
