In many Indian families, there is a practice to eat yogurt after a heavy meal if not every day but very often. It is also served after main course in various traditional occasions like in marriages, family gatherings, parties etc. Although, this practice is thought to be a mere tradition, many are unaware of the scientific reason behind it. Well, it is not simply a dessert served after food for its taste but because of its health benefits. Yogurt is loaded with nutrients, minerals and vitamins and hence eating a bowl of yogurt is considered to be very healthy and beneficial for health. Therefore, taking its great taste and therapeutic potentials into account, today I will be discussing about the top 11 scientifically proven health benefits of yogurt. Apart from the major health benefits of yogurt, we’ll also discuss about the various nutrients and vitamins that it has to offer.

Yogurt is one of the oldest dairy products made by the fermentation process. When fresh pure milk is kept in a vessel together with the friendly bacteria called “yogurt cultures”, they ferment the natural sugar “lactose” found in the milk.  Slowly the milk thickens and develops a sour taste that is very delicious. In this process of fermentation, we get lactic acid that acts as a preservative and allows the cultured milk to remain fresh for a longer period.

Plain yogurt that is devoid of any artificial colorants helps in proper digestion of food and hence it is served after heavy meals. Yogurt is also very good for your heart, bones, obesity and your overall immune system.

You can make yogurt with different types of milk. If you use skimmed milk, it is going to be free of fat and if you use whole milk, it will have full fat. Yogurt was originally eaten in the Eastern European countries but later became popular with the people of the rest of the world and is today a favorite food recipe of many. It is eaten as a dessert or used in various other recipes to add on to the flavor.

How to choose the best quality yogurt?

Yogurt is healthy for your well-being but you need to choose the best one to reap the maximum benefits and I will help you in that. Here are the basis parameters or points you must keep in mind.

  1. Before buying the yogurt, please do not forget to read the level at first. This is important, as you must know what is included in your food. Read the ingredients list and choose a plain yogurt, which has fewer amounts of added ingredients. Check the sugar levels from the nutrition facts, and go for the ones having good amount of Vitamin D and calcium.
  2. Go for a plain yogurt that has least sugar per serving and avoid the ones containing too much added sugar. This is because the excessive sugar can turn the healthy yogurt to something that is injurious to your health.
  3. Yogurt can be made from all kinds of milk starting from whole milk to low fat milk to fat free milk. Both the full fat yogurt and low fat are healthy and hence can be chosen depending on your food preferences, dietary habits and calorie needs. However, if you are desperately trying to lose weight, go for the low fat yogurt with no added sugar.
  4. Choose the yogurts that has the seal of “Live and Active Cultures” on it and discard the ones that are pasteurized after its production. This is to get the benefits of probiotics or good bacteria.
  5. All yogurts are healthy but if you want the best then go for the Greek yogurt. This is because they are much more nutritious that regular yogurt and contain about twice protein, half the carbohydrates and half the sodium as that of the regular one.
  6. If possible, try to go for the raw yogurt made from the milk of the grass fed animals. This is because raw yogurt contains more nutrients and is healthier. However, in case raw yogurt is not available, buy the organic ones from the grass fed animals.

Precautions regarding yogurt

There are many health benefits of yogurt but as you know, nothing in excess is good so yogurt must also be eaten in moderate amounts to prevent adverse effects. According to the Dietary Guidelines (for Americans), little kids in the age group of 4-8 years can consume ½-2 servings of yogurt, milk and cheese per day while those 9 years and above can go for 3 servings daily.

There is no doubt that yogurt if chosen in the right way is healthy but despite that, it is not suitable for everyone. Here are the few precautions that you must remember.

  • People who are lactose intolerant must avoid yogurt. This is because eating yogurt may result to digestive problems resulting to excessive pain in the abdomen and diarrhea.

However, there are exceptions where some people with lactose intolerance can still tolerate it. Studies say that this is perhaps due the fact that some lactose breaks during production and probiotics helps to digest them. Therefore, it is better to do a trial and error. If it suits you, then continue eating else avoid it.

  • If you are allergenic to milk and dairy products do avoid yogurt. In such cases, if you eat yogurt, the milk triggers reaction that can result to hives, inflammation or anaphylaxis that can sometimes put your life at risk.
  • If you have diabetes or have overweight issues, please avoid the yogurts with added sugars at any cost. You either go for the ones with no sugar or try to avoid its intake.


Yogurt is just not popular for its taste but is very nutritious for your health. It is good for your heart, your brain, digestive system, bones, teeth etc. You have to eat yogurt as per daily recommendations depending on your age and reap the maximum health benefits out of it.

In this article, I have discussed all the health benefits of yogurt backed by scientific facts in details but in order to pick the best, do go for the low fat, plain, unsweetened yogurt without much of the added ingredients. Greek yogurt is also a very healthy option for you. Less is definitely more so try to be careful while buying from the market especially if you are suffering from any health issues like diabetes, obesity etc.

Yogurt is extremely healthy but none can avoid the precautions. Those who are lactose intolerant or are allergenic to dairy products must be careful. However, if you really want to try it, then do a trial first or consult a doctor before consuming.
