Soda cake is just a food and has no special effects.

The sodium content in soda crackers is higher. Due to the addition of sodium bicarbonate, the sodium content in soda crackers is generally higher than that in ordinary biscuits. Excessive sodium intake in the diet can easily increase the burden on the kidneys and increase blood pressure.

The higher the saturated fat content in soda crackers, the crispier the biscuits will be. The fat content of soda crackers is around 20%, with the highest being 30%. Fatty foods may have adverse effects on the gastrointestinal tract, such as stimulating the contraction of the digestive tract, which is likely to slow down gastric emptying and aggravate constipation. It may also accelerate gastrointestinal motility, causing or aggravating diarrhea.

Extended information:

Softcakes are usually salty, with cheese or spices as ingredients in the middle. Soda cake originated in Milton, Massachusetts, USA in 1801. It was named because it produced a "crack" sound when baked. Soda cakes are usually served as a snack, sometimes with soup.

The baking soda added to soda crackers also has a gas-producing effect, which can aggravate the symptoms of gastric bloating and belching in patients with stomach problems. Not only are soda biscuits not good for the stomach, but other biscuits on the market that claim to be "stomach-nourishing" also don't have this effect.

Saltine biscuits cannot improve appetite and nutritional status, and will be counterproductive if eaten often.
