[Nutritional Analysis]
Spinach is rich in nutrients, known as the "King of Vegetables", but spinach contains a lot of oxalic acid (about 300 mg of oxalic acid per 100 grams of spinach). Tofu contains more magnesium chloride, calcium sulfate, both if the same time into the human body, will generate insoluble calcium oxalate, not only will cause calcium loss, may also be deposited into the stone. So it is best not to eat spinach and tofu together. In fact, spinach does not contain the highest amount of iron, but also can not supplement blood, because spinach only 10% of the iron absorbed in the intestines, the other 90% are combined with oxalic acid into an insoluble substance, not only difficult to absorb, but also affect the body's absorption and utilization of iron, so a single spinach should not be eaten once too much.

In the calcium and oxalic acid ratio of 1:2, it is most likely to form stones. Stones can be prevented by disrupting this ratio through food combinations, such as pairing spinach with calcium-rich sesame seeds, milk, or fish.
The nutritional value of food protein depends on the type and quantity of amino acids that make up the protein and the ratio between them. The protein content of tofu is high, but because of the methionine (one of the essential amino acids) content is low, so its nutritional value is greatly reduced. But just other methionine-rich plant and animal foods and tofu can be cooked together to avoid the shortcomings, such as adding various types of minced meat in the tofu, or eggs wrapped in tofu fried.
Tofu is rich in calcium, but if you eat tofu alone, the body's absorption of calcium utilization is quite low. If the tofu and vitamin D-containing foods with cooking, but the body's absorption of calcium can be increased by more than 20 times, such as fishheads roasted tofu, not only light and delicious, but also nutritious.
Tofu also contains a variety of saponins, which can prevent the production of lipid peroxide, inhibit fat absorption and promote its decomposition; but saponins can promote the excretion of iodine, which can easily cause iodine deficiency. So often eat tofu, should be appropriate to increase the intake of iodine. Kelp is rich in iodine, will be tofu and kelp to eat together, can be the best of both worlds.
