Understanding Oxalates: Sources, Health Impacts, and Foods to Watch Out For

Oxalates are naturally occurring substances found in various foods and the human metabolism, with potential implications for kidney stone formation and calcium absorption. Foods high in oxalates include rhubarb, chocolate, berries, nuts, grains, and leafy greens like spinach. Managing oxalate intake is crucial for maintaining kidney health and overall well-being.

1. Oxalates Student: Adis Lizalo Prof. Dr. Zeki ACAR

2. naturally-occurring substances found in a wide variety of foods many plants and animals and in our human metabolism strong acids constructed out of two carboxylic acids "oxalate" and "oxalic acid

3. overaccumulating inside our body kidneys urine with calcium oxalate salts 5-15% of all persons are estimated to develop some form of kidney stones

4. 20-40% of the oxalates in our blood come from the foods we eat creating them from hydroxyproline in our liver taking vitamin C and transforming it into oxalate having our red blood cells synthesize oxalates from glyoxylate. amino acids like

5. plant and animal foods rhubarb / 450-650 milligrams chocolate / 250 milligrams berries, which typically contain between 10-50 mg (gooseberries can contain 60-90 mg) lemon (80-110 mg) nuts besides the high-oxalate nuts listed earlier (40-350 mg) legumes (10-75 mg): grain flours (40-250 mg)

6. Among fruits, vegetables and other food items the biggest oxalate sources are: blackberries blueberries raspberries strawberries grapes fig spinach cashews cocoa black and green tea

7. Two aspects of oxalates have been extensively studied from a health perspective: their relationship to kidney stone formation their relationship to calcium absorption and metabolism.
