The Role of Ascorbate in the Nitrate-Nitrite-Nitric Oxide Pathway: Integrating Insights from Earthworm Express
This article integrates insights from Earthworm Express to further explore the biochemical reactions facilitated by ascorbate and the broader implications of the nitrate-nitrite-NO pathway for health.
4 Feb 2023Eben van Tonder Introduction How does ascorbate or Vitamin C prevent nitrite from reacting with secondary amines to form nitrosamines which can be cancer-causing? The meat curing industry uses ascorbate wherever nitrite is used, thus mimicking conditions in leafy green vegetables. More than this, the interplay between dietary components and physiological mechanisms has profound…

The Low Risk of Nitrosamine and Amine Formation in Bacon: Temperature Evaluation
Last consideration for the week: High temperatures form amines in meat. Bacon frying seldom rich these temperatures. So, amine formation is exceptionally low. Ascorbate (Vitamin C) is present. Nitrites are low. Risk is ZERO! Have a great week with bacon!!
The potential health risks associated with consuming processed meats like bacon have been a topic of discussion and research for many years. Central to these concerns are nitrosamines and amines, compounds that can form during the cooking process and have been linked to various health issues, including cancer. However, a closer examination of the cooking temperatures typically used for frying…

The Human Body: A Self-Repairing and Fat Storing Machine
Here I unpack our bodies propensity to store fat. I also show our body's self-healing and repairing ability and I compare it with other animals and their fat-storage ability.
4 Feb 2023Eben van Tonder Introduction Over the last few weeks, I delved into the mechanism of breaking down proteins into amino acids and the problem that can be created through amines if we consume food where the amino acids have been broken down further into these smaller units. Our body uses the amino acids to build proteins and thus repair itself. Protein is thus the key to understanding…
