Do you think that all germs or bacteria are harmful for your body and health? If you do, then you need to know about live microorganisms called probiotics. Probiotics are very healthy, as they stimulate your digestive enzymes and support your immune system but taking too many probiotics is safe or not. Abundantly found in fermented foods and other supplements, these organisms have proved beneficial to human health in both short and long run. Firstly, let us check the health benefits of probiotics before delving deep into it.

Health benefits of probiotics:

gut bacteria

They restore the balance of the gut bacteria in your digestive system. Our gut is home to trillions of microorganisms more than the total cell count of our body. These are diverse in communities and are responsible for healthy digestive, metabolic and immune functions of our body. 

An imbalance of the gut bacteria in your digestive system means that the bad bacteria in present there have outnumbered the good bacteria. When this happens, your body in general and digestive system in particular suffer from several ailments like cramps, gas, bloating, constipation, and diarrhoea, etc.

Probiotics work in helping to replenish the good bacteria in the gut. This, in turn, will help in re-establishing the natural balance of the gut and in keeping you healthy and safe from these ailments in the long run.

This fat is not stored in the body and is excreted with the waste, thus reducing belly fat significantly. This is why probiotics are often considered as very effective cures for conditions like obesity.

Excellent foods that are a rich source of probiotics

However, it is always better to gain probiotics from natural sources instead of dietary supplements. Here, we tell you about a few such natural sources that should be included in your diet.

Live-cultured yogurt

Live-cultured yogurt

Yogurt is one of the best probiotic foods. However, you should know about the health claims made by different brands so you may choose a product with more probiotics and less artificial flavors and sweeteners. Prefer handmade yogurt or one made of goat milk.

Good bacteria like lactobacillus or bifidobacteria present in the yoghurt can help to keep a healthy balance in your gut. There are lots of special digestive brands now available in the market, but be cautious of the ones filled with artificial sweeteners and corn syrup. Read the label carefully before you pick them off the counter.

Fermented cheese

You may go for varied types of cheese, such as Swiss, cheddar, or Gouda. Select the cheese that is fermented with lactic acid bacteria. It will be rich in probiotics.



Kefir is a fermented milk drink and originated with shepherds of the North Caucasus Mountains. A beverage from Russia and Turkey, Kefir is made by fermenting milk from sheep, goat, or cow. This milky beverage contains around 20kinds of good bacteria.Kefir can even help people who are lactose intolerant. You can use it to make healthy smoothies.

This yoghurt-like drink is rich in lactobacilli and bifidus bacteria and helps balance your inner ecosystem. It also has a few beneficial yeast varieties in them, making it rich in antioxidants, a good source of protein and vitamin B. The best way to consume it is to make it at home.

Other advantages include reducing allergy symptoms, boosting immune systems and a rich source of Vitamins A, B , C, and E. While choosing sauerkraut, go for the unpasteurized ones because pasteurization kills the active, beneficial bacteria that the product is known for. It should also be noted that the low pH and the abundance of the lactobacillus bacteria present may upset the intestines of people who are not used to consuming acidic foods.

Latest studies have shown that dark chocolate with at least 70 percent cocoa is a good source of probiotics. It states that a good quality dark chocolate has the survival of up to four times the amount of bacteria as those contained in other dairy substances. By consuming dark chocolate, you are providing enough probiotics for your body to ensure maximum activity on the intestinal microflora. The probiotics in chocolate colonises your large intestines thereby enhancing the growth of lactobacillus and bifidobacterias. A negative aspect would be the fact that chocolate is rich in fat. So eat in moderation.

Sour pickles

General recommendation is having probiotics through whole foods which helps in overall nutrition, a better option than supplements. Research has found that probiotic-rich foods deliver more micronutrients which is not available in supplements. Many plant-based fibers act as prebiotics contributing to the healthy balance of probiotics and prebiotics.

Probiotic supplements have distinct advantages: 

You get more targeted bacteria


Supplements can provide you with the targeted bacterial strains that your body is lacking which might help in addressing a specific health issue. A specific lactobacillus acidophilus strain helps in relieving symptoms of lactose intolerance another strain may help in controlling antibiotic-assisted diarrhoea.

You get diverse forms of bacteria

More diverse the bacterial colony of your gut better it is for your health. Specific supplements aid in creating diverse colonies.

Allergen-free supplements serve the purpose better

Many supplements are allergen-free and are beneficial for those allergic to soy, gluten, wheat, etc.

Live probiotics matter


Whatever probiotic foods you choose be it kimchi, kombucha, tempeh, miso, or kefir it should contain live cultures of bacteria while consuming.  Food processing and storage pose often pose challenges in maintaining the healthy population of live bacteria. Therefore, while buying yoghurt, kefir or tempeh make sure it contains ‘live’ or ‘active cultures’. Pasteurization kills live bacteria. Choose unpasteurized products. Vinegars used in pickles is devoid of probiotics. Choose pickles those not soaked in vinegars.

CFUs (Colony Forming Units) are important

Not consuming the right quantity of bacterial population may not serve the purpose of probiotic consumption fully.  Although there is no standard unit, consuming probiotic with live bacterial population ranging from 1 billion -10 billion CFUs is considered perfect.

For example, CFU in homemade yoghurt will be 3 billion cfu/ML. 1 gm of sauerkraut may contain 1000-100 million CFUs. 1 tablespoon of milk Kefir may contain 150 billion CFUs.

But more is always not the better. It is better to consult your physician while considering the right probiotic.

How to decide between probiotic foods and supplements? 

Ask yourself the following questions:

If yes, you are providing essential nutrients in your body and do not need any supplement. If no, you can look for suitable supplements to get the daily required dose of probiotics.

  • Do you need to address a specific disorder or symptoms?

If yes, you may need a targeted probiotic supplement in consultation with your practitioner. If no, continue eating diverse good quality probiotic-rich foods for better health.

Can you take probiotics daily?

Probiotics are not medicines but supplements most of them are safe for daily consumption. However, there are possible downsides that may vary from person to person.

Recent research published in Cell Host and Microbiome suggests, the nature of evolution of probiotics in the gut under specific conditions could be harmful. Probiotics beneficial to one person can be harmful to another mainly due to personalized nutrition requirements. Even all probiotic foods do not suit everybody’s gut. If you are planning to take probiotics daily, a physician consultation is recommended.
