Yogurt with Lactobacillus Acidophilus

Ever seen those commercials where people eat yogurt to regulate their digestive system? There are reasons yogurt is touted as a health food, and lactobacillus acidophilus is one of them.

Lactobacillus acidophilus is a type of “helpful” bacteria that’s found naturally in the body, usually in the intestines, mouth, or female genitals. It’s considered useful for human health purposes because the bacteria doesn’t cause disease. It also produces vitamin K and lactase, the enzyme that breaks down the sugars in milk products.

Lactobacillus is a popular probiotic. Probiotics are live bacteria that help the body absorb nutrients and maintain the right balance of helpful bacteria. They’ve been used to treat several medical conditions, like diarrhea, lactose intolerance, eczema, asthma, vaginal infections, and irritable bowel syndrome (IBS). However, not every type of bacteria does the same thing. Different strains have different health benefits.

When yogurt is made, manufacturers use these live cultures or probiotics to make the milk thicker and give it the well-known sour taste associated with yogurt.

How Can It Benefit Your Health?

Some antibiotic treatments kill good bacteria along with the infectious bacteria they’re meant to destroy. This may cause unpleasant symptoms, such as an upset stomach. Taking probiotics can also help to restore the good bacteria and reduce these symptoms.

Heart Health

A few different types of probiotics, including lactobacillus acidophilus, are beneficial to heart health. Research has shown that eating yogurt with these probiotics may help to lower low-density lipoprotein (LDL) or “bad” cholesterol, while raising high-density lipoprotein (HDL) or “good” cholesterol.

8 Reasons Why Greek Yogurt Is Good for You

Lactose Intolerance

People who are lactose intolerant are told to avoid dairy. Yogurt is usually the only exception to the rule. This is because yogurt has less lactose than milk and other dairy products. Lactobacillus acidophilus is one of the probiotics in yogurt that’s responsible for reducing the lactose, making it easier for the body to digest. The live cultures also promote good gut health in general, even for people who don’t have trouble digesting lactose.

Diabetes

Yogurt has also been recommended as a healthy food for people with diabetes, and not just because of its high protein content. Lactobacillus acidophilus is also one of the probiotics that can take sugars from food in your digestive system and turn them into a fatty acid that can be used for energy. By reducing the sugar, lactobacillus acidophilus is helping to prevent blood sugar spikes.

Yeast Infections

Since lactobacillus acidophilus is naturally found in the vagina, eating yogurt with the probiotic is sometimes recommended for women who frequently get yeast infections. Researchers believe that replacing good bacteria by eating yogurt could help to maintain the correct balance and keep yeast from overgrowing. Numerous studies have found that consuming probiotics daily did help to prevent yeast and other bacterial infections.

Which Yogurts Contain It?

Lactobacillus acidophilus can be present in different styles of yogurt, from regular to frozen to Greek. To find out if a particular yogurt has lactobacillus acidophilus, check the ingredient label. The bacteria should be listed. 

Here are some common brands that have lactobacillus acidophilus:

  • Chobani
  • Dannon
  • Yoplait
  • Fage
  • Stonyfield
  • Siggi

In order to help people differentiate between brands containing live cultures and those that don’t, the National Yogurt Association (NYA) has created a “live and active cultures” seal. Manufactures must provide NYA with lab evidence that their refrigerated products contain at least 100 million cultures per gram, and frozen products have at least 10 million cultures per gram at the time of production. However, since NYA is not a regulatory organization, it’s still a good idea to check the ingredient list to see which specific probiotics are included in the yogurt you plan to purchase. Additionally, not all manufactures register with NYA, some may choose to simply list the types of bacteria and numbers on the ingredients list or create their own label.
