Oxalic acid is one of the most acidic organic acids in bodily fluids. This organic acid is derived primarily from fungus (Aspergillus and Penicillium), Candida, or your metabolism. Excessive consumption of high oxalate foods and deficiencies in vitamin B6 can contribute to elevations in oxalic acid.
Many of the foods very high in oxalates are healthy foods. High oxalate foods include spinach, beets, chocolate, peanuts, wheat bran, tea, berries, and nuts (cashews, pecans, and almonds).
Testing oxalate levels are important because high oxalates can be very dangerous. Oxalate crystals have a sharp physical structure that can cause oxidative damage, increase inflammation, cause pain, and damage tissues.
Oxalate crystals may form in joints, blood vessels, muscles, kidneys, lungs, heart, thyroid, eyes, and even the brain. High oxalic acid can hinder the proper function of vital bodily functions, poison the mitochondria, and contribute to kidney stones.
High oxalates in the GI tract may significantly reduce the absorption of essential minerals such as calcium, magnesium, zinc, and more. Oxalates may form in the bones, crowding out bone marrow cells. This can lead to anaemia and immunosuppression. Identifying elevated oxalate metabolites is significant for people with chronic pain, joint issues, kidney stones, and other health issues.
