Yakult Vs Yogurt: A Detailed Comparison

Yakult and yogurt are both probiotic foods that offer various health benefits. But what exactly sets them apart? This comprehensive guide compares yakult and yogurt side-by-side, examining their key differences in ingredients, gut-health benefits, taste, cost, and more.

If you’re short on time, here’s the key difference: Yakult is a fermented milk drink that contains lesser quantity but a more concentrated dose of probiotics than most yogurts.

Basic Ingredients

Yakult Basic Ingredients

Yakult is a probiotic drink that originated in Japan and has gained popularity worldwide. It is made from a combination of several basic ingredients that work together to provide its unique health benefits.

  • Lactobacillus casei Shirota: This is the special strain of bacteria that gives Yakult its probiotic properties. Lactobacillus casei Shirota is known for its ability to survive the harsh conditions of the stomach and reach the intestines alive, where it can promote a healthy balance of gut bacteria.
  • Sugar: Yakult contains a small amount of sugar to enhance its taste. However, the sugar content is relatively low compared to other sweetened beverages.
  • Water: Water is the main component of Yakult, making up most of its volume.
  • Skimmed Milk Powder: Yakult also contains skimmed milk powder, which provides a creamy texture and contributes to its overall nutritional profile.
  • Flavorings: To add a pleasant taste, Yakult may include natural or artificial flavorings such as vanilla or fruit extracts.

Yogurt Basic Ingredients

Yogurt, on the other hand, is a dairy product that is made through a fermentation process. It is known for its tangy flavor and creamy texture. The basic ingredients used in the production of yogurt are:

  • Milk: Yogurt is typically made from cow’s milk, but it can also be made from goat’s milk or sheep’s milk. The milk is heated to kill any harmful bacteria and then cooled before adding the starter culture.
  • Starter Culture: This is a combination of live bacteria, including Lactobacillus bulgaricus and Streptococcus thermophilus, which are responsible for the fermentation process. These bacteria convert lactose (milk sugar) into lactic acid, giving yogurt its characteristic tangy taste.
  • Additional Probiotic Cultures: Some yogurts may also contain additional probiotic cultures, such as Bifidobacterium and Lactobacillus acidophilus, which provide extra health benefits.
  • Flavorings and Sweeteners: Yogurts can be flavored with various natural or artificial flavorings, such as fruits, vanilla, or chocolate. Sweeteners like sugar or honey may be added to enhance the taste.

It is important to note that while both Yakult and yogurt contain probiotics, they differ in terms of the specific strains of bacteria used and the overall composition of the product. Understanding the basic ingredients of each can help you make an informed choice based on your preferences and health goals.

Nutrition Facts

Calories and Macros

When it comes to comparing Yakult and yogurt in terms of nutrition, one of the first things to consider is the calorie content and macronutrients. Yogurt is generally higher in calories compared to Yakult.

A typical serving of yogurt contains around 150-200 calories, while a bottle of Yakult contains only around 50-60 calories. This makes Yakult a great option for those who are watching their calorie intake or trying to maintain a healthy weight.

Vitamins and Minerals

Both Yakult and yogurt are known for their probiotic content, which is beneficial for gut health. However, Yakult stands out in terms of the specific strain of probiotics it contains. Yakult contains the strain Lactobacillus casei Shirota, which has been extensively studied for its health benefits.

This strain has been shown to support digestive health, boost the immune system, and even improve skin health.

In addition to probiotics, yogurt is a good source of various vitamins and minerals. It is rich in calcium, which is essential for healthy bones and teeth. Yogurt also provides significant amounts of vitamin B12, which is important for nerve function and the production of red blood cells.

Furthermore, yogurt contains other essential nutrients such as phosphorus, potassium, and magnesium.

This strain has been extensively studied for its potential health benefits, including improving digestion, boosting the immune system, and maintaining a healthy balance of gut bacteria.

Lactobacillus casei Shirota has been shown to survive the acidic conditions of the stomach and colonize the intestines, making it an effective probiotic.

Yogurt’s Probiotic Strains

Yogurt, on the other hand, can contain a variety of probiotic strains, depending on the brand and type of yogurt. Some common probiotic strains found in yogurt include Lactobacillus acidophilus, Bifidobacterium bifidum, and Streptococcus thermophilus.

However, the specific strains and quantities of probiotics in yogurt can vary significantly, so it’s important to check the label to ensure you’re getting an adequate amount.

CFU Count Comparison

CFU stands for Colony Forming Units, which is a measure of the number of viable bacteria in a probiotic product. Yakult contains around 6.5 billion CFUs per bottle, ensuring a substantial amount of probiotics per serving.

On the other hand, the CFU count in yogurt can vary widely, ranging from a few million to several billion, depending on the brand and type of yogurt. It’s important to note that the effectiveness of probiotics is not solely determined by the CFU count, but also by the specific strains and their ability to survive and colonize the gut.

When comparing Yakult and yogurt, it’s clear that both provide probiotic benefits. Yakult offers a specific strain of bacteria with a known track record of health benefits, while yogurt can provide a variety of probiotic strains.

Ultimately, the choice between Yakult and yogurt depends on personal preference and dietary needs. It’s always a good idea to consult with a healthcare professional to determine the best probiotic option for you.
