High level of oxalate for Medjool dates (with details)
1) Medjool dates are high in oxalates (18–233 mg/100 g dry weight).

=>Chemical composition of 17 varieties of Moroccan date fruits (Phoenix dactylifera L.) and to determine their nutritive components. The analysis showed that the dates are rich in sugars (51.80-87.98%), they contain low concentration of proteins (1.09-2.80%) and lipids (0.16-0.39%). The predominant mineral is potassium (1055.26-1604.10 mg/100 g DW). Moreover, they contain high concentrations of malic acid (69.48-495.58 mg/100 g (DW)), oxalic acid (18.47-233.35 mg/100 g DW) and tartaric acid (115.70-484.168 mg/100 g DW).

*The fruits listed under “Low to Medium Oxalate” can still be eaten. They have been put into a separate category because if they are eaten in larger amounts, they can move into the medium oxalate category. I still use them, but just make sure not to overdo it.

(no Medjool date found)
Harvard has released an updated Oxalate list, providing new information on the oxalate content of various foods.
The values on the list may differ due to factors such as growing conditions and measurement methods.
The overall advice for kidney stone prevention remains the same: eat all foods except almonds and spinach products in normal portions.
Other important factors for kidney stone prevention include getting enough fluids, reducing added sugar and salt, and ensuring adequate calcium intake.

Jill is a nurse and health coach that specializes in educating patients on kidney stone prevention. For more than 20 years she's helped patients understand that kidney stones can be prevented with the right treatment plan. It's one thing to be told to lower oxalate or drink more water, but HOW do you do it? That's where she comes in.

Harvard has updated its Oxalate list, providing new information on the oxalate content of various foods. The list includes six new pages of information, including foods that have never been studied before. While the values may differ depending on factors such as growing conditions and measurement methods, the overall advice remains the same: eat all foods except almonds and spinach products in normal portions.

=> The peer-reviewed medical literature doesn’t include dates in the oxalate data testing reports. However, the VP Foundation sponsored tests of dates performed in Laramie, WY at the University of Wyoming by Dr. Michael Liebman and his team. They tested Medjool dates three times, California-grown Deglet Noor dates once, and another unspecified variety grown in Pakistan.2
According to their reported results, 24 grams of pitted Medjool dates (around one date) contains approximately 1–2 mgs of total oxalate. 24 grams of Deglet Noor dates (about three and a half dates) contain around 2 mg.1 No published testing found over 2.5 mg of oxalate per 24-gram serving.
If Dr. Liebman’s testing is right, dates are low oxalate foods. Yet mainstream sources like WebMD and Harvard incorrectly claim dates are high in oxalate, without offering any citations showing where they got this idea. They also failed to indicate the varieties, rendering the data useless.
These “reputable” and familiar institutions are seemingly reporting oxalate data, but not really. Verifiable testing shows them to be flat out wrong. This misinformation, coupled with a lack of transparency, is adding to the confusion around oxalates.
