This blogpost has been preceded by a long thinking pause due to a moral dilemma. When I started writing here, my French Food Philosopher’s objective was to demonstrate that a triple win should be possible. I was convinced that by adopting a 100% plant-based diet we could improve our planet’s sustainability, contribute to a better human health, and reduce animal suffering. By writing here could I help future generations by promoting delicious vegan, or at least vegetarian recipes?
In search of answers and proof for the doubts I had, I followed several courses. At the Wageningen University and Research I followed a MOOC entitled “Plant Based Diets – Food for a Sustainable Future”. At the European Academy for Natural Healthcare in Antwerp I became a food coach. With the online courses of PNI Europe and Natura Foundation I delved into the evolution of Homo sapiens, explored the insights provided by orthomolecular medicine and by clinical psycho neuro immunology (cPNI). Today I present the conclusions I reached after this journey.
The Evolutionary Perspective
The most important insight I developed the past year is to take an evolutionary perspective to understand how we should live. The modern human arose about 300,000 years ago in Africa. Our DNA has not evolved much since then. To comprehend our dietary requirements, we must look at our evolutionary roots. Throughout our history, animal proteins have played a crucial role in shaping our physiology and cognitive development. As hunter-gatherers, our ancestors relied on animal sources for sustenance, which provided essential nutrients, such as complete proteins, long-chain omega-3 fatty acids, iron, and vitamin B12, that were vital for our survival and flourishing. Red meat became only relatively recently a frequent source of protein. This also applies to grain-based foods like bread.
Orthomolecular Medicine
Orthomolecular medicine emphasizes the significance of optimal nutrition for achieving and maintaining good health. It recognizes that everyone has unique biochemical needs so a one-size-fits-all approach does not suffice. The Natura Foundation also promotes an evolution-based approach in which animal proteins offer a highly bioavailable and complete source of essential amino acids. Proteins are the building blocks of life, enabling numerous vital functions in the body, including tissue repair, hormone synthesis, and enzyme production. The course I followed strongly encourages the consumption of vegetables and fruit in combination with fish and other seafood as well as of eggs and poultry.
Clinical Psycho Neuro Immunology
Clinical PNI (or “KPNI” in Dutch) explores the intricate interplay between the mind, body, and immune system. I love the holistic approach of this school of thought and its strong basis in science. It highlights the impact of psychological and emotional well-being on overall health. While plant-based diets can certainly provide adequate nutrition, it is crucial to consider the potential psychological and emotional effects of dietary choices. cPNI highlights several potential health risks associated with the consumption of soy and legumes (e.g. Anti-nutrients and digestive issues). For some individuals, the inclusion of animal proteins in their diet may positively influence their mental health and overall well-being.
Stay Off Mammals
Both cPNI and orthomolecular medicine raise concerns regarding the consumption of red meat and dairy because of Neu5Gc (N-Glycolylneuraminic acid). This is a type of sugar molecule found in these animal products. Neu5Gc is considered a non-human antigen as our bodies do not naturally produce it. When you consume red meat and dairy products containing Neu5Gc, your immune system may recognize it as a foreign substance, potentially leading to chronic inflammation and triggering autoimmune responses. Red meat and dairy are also known for increasing other health risks. For one I’ve chosen to stay off red meat and considerably limit my consumption of dairy… even cheese !
Ethical Dilemmas and Considerations
I have great respect for those who live a vegan life. Ethical concerns surrounding animal welfare have prompted many to adopt this lifestyle. The ethical argument against the consumption of animal proteins is compelling, as factory farming practices often involve cruelty and environmental harm. Acknowledging these concerns, it is essential to promote ethical and sustainable farming practices that prioritize animal welfare, such as free-range, grass-fed, and organic farming.
Striking a Balance: A Healthy and Sustainable Approach
While acknowledging the ethical dilemmas surrounding animal protein consumption, and the implications on the environment, it is in my opinion realistic to consider the negative health aspects of veganism. A healthy and sustainable approach to diet should consider individual biochemistry, cultural diversity, as well as the environmental impact of our choices. Incorporating a variety of protein sources, including both plant-based and animal options, can provide the necessary nutrients for optimal health while minimising ecological impact.
Conclusion
The question of whether the human diet needs to include animal proteins is multifaceted and requires careful consideration. Exploring the evolutionary perspective, orthomolecular medicine, and clinical psycho neuro immunology reveals the significant role that animal proteins have played in our development as a species.
To achieve optimal health while fostering a more sustainable future, my recommendation is to embrace a diverse diet that focuses on the following basic rules:
- Eat natural: steer away from processed foods.
- Eat the rainbow: consume mostly foods that are alkaline (ph > 7), veggies and fruits.
- Mind your proteins: limit your consumption of acidic foods (ph < 7) but make sure you get enough proteins.
- If you eat animal proteins, ensure the inclusion of ethically sourced produce, preferring fish, eggs and poultry.
- Minimise dairy, avoid eating red meat altogether (for many reasons, more than mentioned above).
Apart from all this: relax, take enough rest, sleep well (check out “the healthy big five“)!
