I am not in any way an expert or a scientist or an educator and am only letting you know what I have found out and what has helped me. Oxalates and salicylates are plant toxins that act as a natural bug repellent and disease inhibitor. Most of the toxins are found in the outer peels or skins of the plants.
I have suffered from RLS my entire life. My mom complained about me being restless and tearing my bed apart at night. I have never been a "good sleeper". I mostly just suffered through it and when I was a teenager, I used alcohol which helped me to sleep. I continued using (abusing) alcohol as an adult and my RLS progressed. My Primary Care Physician put me on tramadol which helped a great deal and I was on that for years without ever upping the dose. My ferritin level is always over 100. After a bee sting in the face at age 52 I was given benadryl to help with the swelling and inflammation. This put my RLS on overload. Even weeks after going off benadryl my RLS was not manageable at all. My PCP started me on ropinirole which I could not tolerate as the daytime sleepiness prevented me from being able to function. I switched to pramipexole which worked...until it didn't and made my RLS so much worse. After 10 years, I weaned myself from the pramipexole but my RLS stayed the same.
One night, searching desperately for something to help that was not a drug, I came across "Notnowdad's" post about being free from RLS for years because of a low oxalate eating plan. I am not a stranger to elimination diets as I have Hashimoto's Thyroiditis and had established an eating plan that was successfully keeping it under control. I looked at lists of high oxalate foods and realized that most of my diet consisted of VERY HIGH oxalate foods especially potatoes, spinach, almonds, tea, herbs, cacao and spices and a many more healthy foods.
I stopped eating foods with high oxalates and after one day I did not have RLS that next night.
I was still restless during the day and night and started looking into salicylates as a potential cause. Reducing salicylates has reduced my restlessness to where it is non-existent and as a side benefit has reduced my allergies to the point where I don't even think about them anymore.
Using a food log I found that my safest foods are white rice, eggs, dairy, meat and fish. I eat very little processed foods and any processed meats I eat are nitrate, sugar and sulfite free. I eat gluten free rice pasta. I use mostly maple syrup and sometimes refined sugar as a sweetener. I use salt and white pepper. I use sunflower oil. I eat pecans, walnuts, sunflower seeds and pumpkin seeds. I drink coffee daily, but only one cup as it can interfere with sleep. Otherwise I only drink water and water with lemon juice. The peel of the lemon contains oxalates so I never use that anymore. Any plants that I eat I try to determine if it's a low o/s plant first and I ALWAYS peel plants before cooking or eating. Many herbs, spices, teas and plant oils have highly concentrated amounts of oxalates and salicylates so I avoid most of them and look up anything I want to eat to determine if it's high in o or s before I use it. I am gluten free and eat few goitrogenic plants as they adversely affect thyroid conditions. I don't eat bananas as they seem to always trigger RLS in me but I don't know why. Asparagus also seems to trigger RLS, even organic asparagus, but I don't know why.
I have been on this eating plan for a year now and have had tremendous success! I feel that o/s build up in my body over time so I try to take a day or two a week and only eat my safest foods.
I have been adding some plants back into my plan to see how they affect me. I ate some french fries this week, maybe ten thin fries and had RLS and PLMD the next night.
I don't take any medications or supplements. I don't drink alcohol anymore.
I hope this helps someone like the info from "Notnowdad" has helped me - actually it saved my life.
I'm happy to answer any questions you might have.
I wish you all peaceful rest.
