The Effects of Drinking Bad Soy Milk

By Brenda Priddy

Soy milk is often used as a replacement for cow’s milk by health conscious people and among vegetarians. However, even though soy milk is plant based, it can still expire just like normal milk. If spoiled soy milk is ingested, it may cause definite symptoms. If symptoms persist for more than one day, consult with a health care provider on the best course of action.

Stomach Ache

One effect of drinking bad soy milk is a stomach ache. Drinking any spoiled product may cause stomach problems, and soy milk is no exception. Usually a stomach ache will appear within a few hours of drinking the spoiled milk. The best way to avoid drinking spoiled soy milk is to use a permanent marker to write down the date that you opened the milk. Five to 7 days later, throw the milk away.

Vomiting

If you drink a lot of spoiled soy milk, it is possible that it may cause vomiting. Vomiting will usually show up 8 to 24 hours after drinking the spoiled soy milk, just like regular food poisoning. If vomiting occurs, do not try to suppress the vomiting because your body is cleaning out the toxins that the spoiled milk brought in.

Diarrhea

If vomiting does not occur, or perhaps in conjunction with vomiting, diarrhea may occur. This is another way that the body tries to cleanse itself of the spoiled milk. Diarrhea may occur after a stomach ache or it may occur without any previous symptoms. If you have diarrhea, drink a lot of water to keep hydrated.

Cramps

Cramps are a likely adverse effect from drinking bad soy milk. Spoiled soy milk may cause the stomach to contract, causing minor or major cramping. Cramping can sometimes be alleviated by drinking water. Cramps may be an indication of a worse symptom to come, such as diarrhea.

Headache

Occasionally, drinking spoiled soy milk may cause headaches. Headaches will usually occur if the drinker already has an allergy or sensitivity to soy products. If desired, you can take a pain reliever to help reduce the pain of the headache. Resting or sleeping may also help with pain.

Taste/Texture

Bad soy milk may show a change in taste or texture. The milk may taste sour and have a stronger scent than normal. The texture of the milk may become thicker, with curds or lumps present. If you notice these symptoms in your soy milk, throw the milk out immediately.
