What are Oxalates?

This is a subtitle for your new post

What are Oxalates?

Oxalates are a protective mechanism from plants to discourage animals from eating them too much. When consumed in excess or when the body is not working at optimal function, they can accumulate in the body.

 

How do they impact the body?

Tiny oxalate crystals accumulate in different places in different people. The most commonly known oxalate accumulation is as kidney stones. However crystals can also 

 settle beneath the skin (and therefore suffer from 'mystery' eczema and has also be linked to vulvodynia) 

 store in the joints (and therefore suffer from 'mystery' pain in the knees, hips, etc). 

 store in the central nervous system, which is where they can cause all sort of symptoms (from poor balance, anxiety to poor memory).

 

Food sources

Oxalates are found in a range of foods, some of the highest quantities are in spinach, beetroot, dark chocolate and almonds. So whilst some people can benefit from these in their diet , others won't – we are all different. So if you are in ill health, maybe hold back on the spinach smoothies….

 

How do you know you have oxalate accumulation? 

Well you often don't!. When the body is high in oxalates, we see raised levels in the urine as the body tries to eliminate them. Some people can see their crystals as their urine sparkles, so check by shining a light on the toilet bowl or hold a urine sample to the light ( disco wee!).


For me this wasn’t the case ( no disco wee). When running an Organic Acid test with my nutritionist Marek Doyle too look for clues for what wasn't working well and could be contributing to my CFS, we saw my oxalates were very high. We then instigated an oxalate protocol. Improvement is not always instant, as the oxalates come out in waves, know as ‘dumping’ where you can feel worse, then better again. However, over the months I noticed an improvement in my health. For me this was a part of my healing journey ( look out for my mould/ VCS article to come) , for others this is the key blocker to regaining their health.

 


 My organic acids results in 2014 showing high oxalates - see marker 21 out of range


My Organic acid retest in 2019 showing back in range 



Oxalates are not a forever thing, now I have cleared my accumulation I can eat occasional high oxalate food, I just do so in moderation

The Organic Acid Test (OAT) is a great comprehensive nutritional screen that I recommend, which can pick up if oxalates and other issues such as your detoxification pathways, energy pathways and gut health are all in optional range. If you are interested in testing them please contact me.

This is one of my current favourites. Batch make and put what you don’t need in freezer to grab and go on busier days. Great balance of protein, natural fats and veg!

These are a standard of mine, quick to make, nice to eat, as it should be.

Magnesium is the fourth most abundant mineral in the body, every cell in your body contains it, and needs it to function. Magnesium is involved in more than 300 metabolic reactions in the body (1), including · Energy creation: Helps convert food into energy. · Nervous system regulation: Magnesium has a calming influence, regulating neurotransmitters, that send messages throughout your brain and nervous system, and can help sleep and aid depression (2) · Protein formation: Helps create new proteins from amino acids. · Gene maintenance: Helps create and repair DNA and RNA. · Muscle movements: As part of the contraction and relaxation of muscles. Magnesium is safe and widely available The Nutrient Reference Value (NRV) for Magnesium in the EU is 375mg a day. In the U.S the recommended daily intake (RDI) is 400–420 mg per day for men, and 310–320 mg per day for women. Studies suggest that about 50% of people in the US and Europe get less than the recommended daily amount of magnesium ( 3 & 4). Why? We can’t say for certain but is thought to be due to depleted soils and over refining that reduces mineral content. Some stomach, kidney and pregnancy medically diagnosed conditions can also reduce magnesium availability (5). For all medical conditions it is important to consult your GP first. You can get magnesium from both food and supplements. Food Sources The following foods are good to excellent sources of magnesium: (6) · Pumpkin seeds: 46% of the RDI in a quarter cup (16 grams). · Dark chocolate (70–85% cocoa): 33% of the RDI in 3.5 ounces (100 grams). · Black beans: 30% of the RDI in a cup (172 grams). · Quinoa, cooked: 33% of RDI the in a cup (185 grams). · Halibut: 27% of the RDI in 3.5 ounces (100 grams). · Almonds: 25% of the RDI in a quarter cup (24 grams). · Cashews: 25% of the RDI in a quarter cup (30 grams). · Mackerel: 19% of the RDI in 3.5 ounces (100 grams). · Avocado: 15% of the RDI in one medium avocado (200 grams). · Salmon: 9% of the RDI in 3.5 ounces (100 grams). Supplements Magnesium can is readily absorbed through the skin. For this you can · Soak for 20 mins in a warm bath with 500g of epsom salts · Spray magnesium oil straight onto skin – spray onto your feet at bedtime for maximum absorption and a great sleep Alternatively · Take high bioavailability ( high absorption in your stomach), such as a chelated magnesium supplement, avoid magnesium oxide which is very low absorption References 1.
