I’m a beginner with the Paleo Diet. I want to try it out but I’m a vegetarian (I eat tofu, seitan, tempeh, fish, eggs, and cheese as replacements for meat). I understand I have to leave out the beans, but is it ok to use the rest of the replacements ? Thank you for an answer.
Maelán Fontes’ Response:
The Paleo Diet is based on foods similar to what our hunter-gatherer ancestors ate during the paleolithic era 2.6 million year to 10,000 years ago. That translates into 99.6 % of our evolution history. Our genome is perfectly adapted to eat foods similar to what we found during that period of time. This means eating grass produced or free ranging meats, seafood, vegetables, fruits, and nuts. The agricultural revolution (10,000 years ago) lead to a dramatic change in human nutrition. Cereal grains, legumes, dairy, vegetable oils, salt, alcohol, and refined sugars comprise 72% of the nutrition in the modern western society. These foods contain harmful substances associated to many “diseases of civilization”, such as diabetes, celiac disease and other autoimmune diseases, obesity, hypertension, certain cancers, acne, polycistic ovary syndrome, myopia, dyslipidemia, cardiovascular disease, etc.
Tofu and tempeh are sources of soy bean agglutinin (SBA). SBA has harmful properties because they break cell membranes. This can induce increased intestinal permeability, which is associated to certain autoimmune diseases and low-grade inflammation. SBA has also been shown to stimulate the immune system, something we don’t want in an inflammatory disease.
Seitan contains the worst part of wheat namely gluten. Gluten is a prolamine peptide associated to many diseases typical of western civilization, such as celiac disease, type 1 diabetes, multiple sclerosis, ataxia, rheumatoid arthritis, etc.
So, if you want to eat a paleolithic diet without eating meat you should ensure a good protein intake using egg powder protein shakes along with some supplements:
- Vitamin B12 1 mg per day
- Taurine 1 gram per day
- Carnosine 800 mg per day
- Carnitine 400 mg per day
I hope this helps.
