What in spinach blocks calcium absorption?
Spinach and Other Foods with Oxalates

Does oatmeal block vitamin absorption?
1) Soak your oats
Grains contain phytic acid, which, when untreated, combines with calcium, magnesium, copper, iron and zinc within the intestinal track. This results in the blocking of the absorption of these minerals.
Does spinach have anti nutrients?
There are many different kinds of antinutrients in foods. Oxalates, found in leafy greens (spinach, beet greens and chard), interfere with your body’s absorption of calcium in these foods. Phytates, found in legumes, nuts, seeds and grains, hold on to important minerals like iron, zinc and calcium.
What should not be eaten with spinach?

Can I take calcium after eating spinach?
Oxalates can bind to minerals and prevent them from being absorbed in the body. The high oxalate content in spinach, for example, can inhibit calcium absorption. But studies have found that if you eat the recommended daily amount of calcium, this effect isn’t seen.
How do you avoid oxalates in spinach?
Cooking Spinach Decreases Oxalates
Researchers found that steaming and boiling were effective cooking methods for decreasing the oxalate content of spinach and other vegetables. Boiling appears to be more effective; it reduced the soluble oxalate content by 30 percent to 87 percent.
Can spinach cause digestive problems?
For some people, raw and cooked spinach causes digestive discomfort, which often includes bloating and excessive gas. In many cases, the only way to prevent this discomfort is to avoid spinach altogether.
What happens if you eat too much spinach?

This is because the Oxalic acid present in spinach binds with zinc, magnesium, and calcium, hindering the body’s ability to absorb the nutrients.
Can you absorb iron from spinach?
A cup of raw spinach has less than 1 mg because of the high water content. But there’s another issue: Spinach is high in oxalic acid, which inhibits iron absorption. Basically, spinach is not a great source of iron.

Cheeseburgers and mac and cheese, for example, are popular examples of protein and starch. “This is the worst combination,” Dr. Gioffre says. “They cancel each other out.” The protein (the meat or cheese) is digested by the acid, called pepsin, in the stomach.
What foods block protein absorption?
Legumes, cereals, potatoes and tomatoes contain inhibitors that reduce protein digestibility by blocking trypsin, pepsin and other gut proteases (Savelkoul et al., 1992; Liener, 1994; Friedman and Brandon, 2001).
Does oatmeal block calcium absorption?
Phytates. Found in high-fiber foods such as berries, corn, nuts, oatmeal, rye and especially wheat bran, phytates are substances that bind calcium, reducing its absorption.
