Tofu Preparation And Its Impact On The Iron Content

It is worth noting that the way in which tofu is prepared and processed have an impact on its iron content. For instance, tofu is stored frozen, canned, or in a box. This soybean product can also be prepared fried, grilled, or eaten raw.

If dried frozen, such as in the case of koyadofu, the iron content is higher at 9.73 milligrams per 100-gram serving. On the other hand, raw tofu with calcium sulfate added in the manufacturing process brings the iron content to 5.36 milligrams for the same serving size.

If buying tofu that is not dried-freeze, it is worth preparing this food in a way that will help to preserve as much iron as possible. Eating tofu raw is more ideal, especially tofu that contains calcium sulfate in it. By doing so, you can get 6.65 milligrams in half a cup serving.

An easy way to incorporate raw tofu into your diet is by adding it into your salad. You can toss in some cubed raw tofu to your green salad or to your sauteed vegetables.

If you prefer it cooked, lightly steaming or boiling tofu should give you as much iron content as you can get compared with deep-frying.

For vegans, you can make plant-based cheeses, mayonnaise, and other dips by adding tofu to these recipes. These cool ideas give you more ways to eat tofu and enjoy the nutritional benefits that it offers.
