Lactic Acid in Food: Benefits and Safety Concern

In our daily lives, lactic acid in food is quite common. It's a chemical that bacteria naturally make when they ferment food. You'll be relieved to learn that this ubiquitous substance provides a variety of advantages, despite the fact that many people doubt if it is safe. This article assesses how lactic acid might affect your health.

When food undergoes fermentation, bacteria produce lactic acid, a form of organic acid. In order to keep processed foods from spoiling and to improve their flavor, it is occasionally employed as a food preservative. With the exception of infant foods and formula, the Food and Drug Administration (FDA) has allowed its usage in the majority of items.

Lactic acid in food

Lactic acid can be found in a variety of grocery store foods. Lactic acid is a result of fermentation and is present in many nutritious foods, including yogurt and kimchi, as was already mentioned. Cucumbers, leeks, and even ginger are among the pickled veggies that create the food preservative. Several societies use lactic acid bacteria to ferment fruits like papayas and mangoes.

Lactic acid regulates the level of acidity in a variety of foods, including olives, cheese, frozen desserts, and carbonated beverages, claims the Center for Science in the Public Interest (CSPI). According to the CSPI, lactic acid is a safe food ingredient that prevents food spoiling while adding tartness to some meals and balancing the flavor of others.

According to the USDA, lactic acid is used to prevent discoloration in cut fruits and vegetables as well as to enhance the flavor of canned seafood. Lactic acid is also used by brewers to heighten the flavor and improve the fermentation process.

Potential health benefits

Lactic acid is naturally created in fermented foods, unlike the lactic acid added to desserts and fizzy drinks, which may not offer many health advantages.

• Improves gut health: Live probiotics found in fermented foods can improve your gut microbiome by strengthening it. Your immune system, digestion, and even your sleep can all be enhanced by having a healthy gut. The consumption of fermented foods can alter your gut flora, according to a limited assessment of 19 studies, but further research is required.

• Increases nutrient absorption: Your gut occasionally requires assistance in assimilating all the nutrients you consume. Your small intestine may be impacted if the microbiome in your gut isn't "balanced." Supplements containing lactic acid bacteria may enhance nutritional absorption, according to a study of the literature.

• Antioxidant effects: According to one assessment of the literature, fermented meals can also increase accessibility to other substances including vitamins and exopolysaccharides. Your antioxidant activity will increase as a result, reducing the risk of oxidative stress.

Too many free radicals floating around in your cells might cause oxidative stress. Normal metabolism or exposure to substances like chemicals, air pollution, and cigarette smoke can produce free radicals. It harms your body and has been linked to chronic illnesses brought on by aging and poor eating.

• Supports your immune system: According to research, a chemical produced by lactic acid bacteria may strengthen your immune system. This might help in the treatment of inflammatory illnesses. They include ailments including inflammatory bowel disease, asthma, and arthritis.

Should you avoid lactic acid?

The lactic acid in food typically has no adverse side effects. In fact, a review of the literature revealed a benefit to eating foods high in lactic acid.

Lactic acid occasionally shows up when it isn't wanted. Keeping things preserved is one of its primary functions in the food industry, but it can also hasten the deterioration of food. Lactic acid spoiling can be particularly prone to occurring in vacuum-sealed items and low pH (acidic) foods. These include items like salad dressings, tomato-based sauces, and processed meats. You should throw away any milk or salad dressing bottles that bloat up since it is lactic acid-producing gas.
