Expanded Information:

Curd does have a drawback in that it has to have quite a bit of salt in it to help preserve it. The amount of salt in curd products varies from one variety to another, and most products can contain an average of 2-3% sodium, which equates to 5-7.5% salt. Although the curd pieces themselves are less salty than curd juice, with a large piece weighing in at around 20 grams and a smaller piece at around 10 grams, the total salt intake is still considerable.

Based on 5% salt content, 20 grams of soy bean curd is equivalent to 1 gram of salt. So, to enjoy the nutritional value and health benefits of curd, you need to replace the salt in your meals with it, rather than eating the same amount of salt along with two pieces of curd.

Replacing some of the salt with curd increases the availability of nutrients, including a little bit of calcium and magnesium, and adds peptides that are good for controlling blood pressure, without increasing the total amount of sodium. Curd is not as unhealthy as we think, so feel free to eat it.
