Plant foods like spinach, almonds, and sweet potatoes contain oxalates, which are naturally occurring chemicals. Because of their binding properties, they might hinder the body's absorption of certain minerals, such as iron and calcium, when consumed with food. However, no proof that moving to a low-oxalate diet directly helps you gain muscle. You don't have to change everything you eat because of oxalates, but knowing which foods are highest in them and how to pair them with others can help you get more out of every meal.
Bodybuilders often eat a lot of foods that are high in oxalate, like spinach, almonds, and sweet potatoes. Oxalates aren't likely to be your biggest worry, though, unless you or someone in your family has had kidney stones in the past. For most sports, it's much more important to focus on eating well and staying hydrated.
Some of the things that bodybuilders eat every day are also some of the best sources of oxalates. If you eat a lot of these high-oxalate foods without thinking about your kidney health, you may be increasing your risk of oxalate buildup over time without realizing it.
Spinach has the most oxalates, with about 600 to 750 mg per 100g amount. Others that do this are almonds, beets, sweet potatoes, and cocoa powder, which are all popular foods that athletes who are trying to improve their performance and recovery eat.
Even though these foods are healthy, eating them a lot or often may make it harder for your body to absorb nutrients, especially calcium and magnesium, because they bind to oxalates in the digestive tract before the minerals can get into your bloodstream. You can make better decisions without changing your whole diet if you know which foods are higher in oxalates.
Eating a lot of foods that are high in oxalate can make it harder for your body to absorb minerals. When it comes to bodybuilding nutrition, this is important because iron helps muscles contract and calcium keeps them healthy. The effect is mostly limited to the meal itself, though.
Instead of strictly following a low-oxalate diet, eating enough calcium along with foods that are high in oxalate is usually enough to minimize this interference without giving up the essential nutrients you need to perform at your best.
If you're already getting enough protein, staying hydrated, and working hard, switching from sweet potatoes to carbs that are lower in oxalate won't help you make more gains. Not cutting back on oxalate is what causes muscle growth, gradual overload, enough calories, and regular sleep.
For healthy bodybuilders, the nutrients in foods that are high in oxalate often outweigh any possible risks. Instead of taking away things that are good for you, focus on what has been shown to make a difference. Trying to lower oxalate as a performance strategy is probably taking attention away from more important things.
If you want lower-oxalate carbs, swap out the spinach for kale or rocket and pick white rice over quinoa. You don't have to leave out all plant-based things; just change them up more often.
By eating foods that are high in calcium with foods that are high in oxalates, you can stop your body from absorbing the oxalates before they reach your kidneys. Stay hydrated all day, but especially when you're working out.
Try not to turn this into an extreme diet plan. If you cut out too many things that are high in nutrients, you might not get enough fiber, vitamins, and minerals. All-or-nothing changes are not smart unless a doctor has raised a health concern. A moderate, targeted approach is much smarter.
What Are Oxalates and Why Should Bodybuilders Care?
Many plant foods naturally contain oxalates. Your body also makes them as a metabolic byproduct, but dietary sources are usually the ones that get the most attention. Calcium oxalate is what your body usually gets rid of when oxalates join with calcium in your gut. When your kidneys store too much calcium oxalate, which can lead to kidney stones, you have problems.Bodybuilders often eat a lot of foods that are high in oxalate, like spinach, almonds, and sweet potatoes. Oxalates aren't likely to be your biggest worry, though, unless you or someone in your family has had kidney stones in the past.

Do High Oxalate Foods Block Muscle Mineral Absorption?
Not only do bodybuilders need to know which foods are high in oxalates, but they also need to know how those oxalates affect your body's ability to use important minerals. Oxalates join with calcium and iron in your gut, making compounds that your body can't absorb.Eating a lot of foods that are high in oxalate can make it harder for your body to absorb minerals.

Can a Low Oxalate Diet Actually Improve Muscle Gains?
If cutting oxalates from your diet really did help you build muscle, it would already be a common way to train, but there isn't any proof. No research has directly linked lower levels of oxalate in the urine to better performance or faster recovery.If you're already getting enough protein, staying hydrated, and working hard, switching from sweet potatoes to carbs that are lower in oxalate won't help you make more gains.
