What's the calorie content of an old-fashioned rice cracker? It's the kind you get on the street, the hollow kind.

About 360kcal/100g, it's in the same class as rice and white flour. It's just that the larger volume appears to be fluffy. In addition, the puffing process will greatly increase the glycemic index (GI) value. After all, the texture is looser, it's easier to chew, and the digestive enzymes are much more efficient when attacking it.

After all, it's all made of grain, and eating one or two pieces of popcorn (50 grams of dried corn kernels) requires eating half a bowl of rice (50 grams of rice) less. Traditional popcorn has the worry of lead contamination from a small converter, and newer popcorn has the worry of high saturated and trans fats. 2 taels of popcorn = 2 taels of dried corn kernels = 2 taels of dried rice (a small bowl of rice) = 2 taels of white flour (a large steamed bun).

Expanded Information

Traditional popcorn is made from corn that has been heated at high temperatures in a small converter, which may have some saccharin added for flavor, but does not have any margarine-based fats added. While traditional popcorn is not high in fat, traditional small converters may release lead at high temperatures.

The reason for this is because the sealing layer of the traditional small converter is made of cast iron containing lead, and since the melting point of lead is only 327.4 degrees Celsius, a large amount of lead vapor escapes when it is heated to 400 degrees Celsius to 500 degrees Celsius. And in the production process of popcorn, its instantaneous temperature up to about 400 ℃.

So, in the high-pressure heating, a certain amount of lead in the pot will melt, part of the lead will become steam and lead fumes, contamination of raw materials, especially in the "pop" moment, the lead is more likely to be adsorbed in the fluffy rice flowers.

Lead is absorbed by the body, will harm the nervous, hematopoietic and digestive systems, very easy to occur chronic lead poisoning, and can lead to children's appetite, diarrhea, irritability, purple gums, decreased resistance, slow growth and development.
