We’ll examine its ingredients, nutritional value, and potential benefits and downsides.

Is Yakult Healthy & Does It Boost Your Immunity?

Is Yakult Healthy

So let’s get started and find out if Yakult deserves a spot in your daily routine!

What is Yakult?

Yakult is a Japanese probiotic milk drink. It contains a special strain of bacteria called Lactobacillus casei Shirota.

Yakult is one of the world’s top probiotic drinks. The company claims that over 40 million bottles are consumed globally every day!

But what exactly are probiotics, and why are they important?

Probiotics 101

Our gut is home to trillions of bacteria, both good and bad. These bacteria play a crucial role in digestion, nutrient absorption, and immune function.

Probiotics are live beneficial bacteria. They help maintain the balance of gut bacteria, preventing the bad ones from taking over.

When this balance is disrupted, it can lead to digestive issues, weakened immunity, and other health problems.

That’s where probiotic foods and drinks like Yakult come in. They help replenish the good bacteria in your gut.

Key Ingredients in Yakult:

Now that we know the basics, let’s look at what Yakult contains:

  • Water
  • Sugar
  • Skimmed milk powder
  • Glucose
  • Lactobacillus casei Shirota (the probiotic strain)
  • Flavors

While the ingredients seem simple, some components like sugar have raised concerns. We’ll address those later.

Nutritional Information per 65ml Bottle

Here’s a quick breakdown of Yakult’s nutritional value per 65ml bottle:

Nutrient Amount
Energy 50 calories
Protein 0.8g
Total Fat <0.1g
Saturated Fat <0.1g
Carbohydrates 11.5g
Sodium 10.1mg

As you can see, Yakult is relatively low in calories, fat, and protein. However, it does contain a significant amount of carbohydrates, mostly from sugar.

The Yakult Review 2024 with Pros and Cons:

Now, let’s dive deeper into the potential benefits and drawbacks of consuming Yakult.

1. Amount of Sugar

One major concern with Yakult is its high sugar content. Each 65ml bottle contains around 10 grams of sugar.

The recommended daily sugar intake is 20-25 grams. If you consume the suggested 1-2 bottles of Yakult per day, you’re already getting 10-20 grams of sugar from this drink alone.

Add to that the sugar from other foods and drinks, and you could easily exceed the recommended limit.

Excessive sugar consumption is linked to various health issues, including:

  • Obesity
  • Diabetes
  • Cardiovascular diseases

To address this concern, Yakult also offers a “Light” version with lower sugar content. We’ll compare the two versions later.

2. Type of Bacteria (Lactobacillus casei Shirota)

The star ingredient in Yakult is the probiotic strain Lactobacillus casei Shirota (LcS).

This strain is unique because it can survive the harsh acidic environment of the stomach and reach the intestines alive.

Once in the gut, LcS can:

  • Inhibit the growth of harmful bacteria
  • Promote a healthy gut flora balance

Each bottle of Yakult claims to contain 6.5 billion LcS bacteria. In comparison, a cup of yogurt typically has around 240 million probiotic bacteria.

So, in terms of probiotic potency, Yakult seems to pack a punch.

3. Skimmed Milk Powder and Glucose

Yakult contains skimmed milk powder, which serves as a growth medium for the LcS bacteria.

Since it’s skimmed, the fat content is relatively low. However, the milk powder itself doesn’t offer any significant additional benefits.

Glucose is added to Yakult to feed the probiotic bacteria and extend the product’s shelf life.

4. No Added Preservatives

One advantage of Yakult is that it doesn’t contain any artificial preservatives.

The probiotic bacteria in Yakult create an acidic environment that prevents the growth of other harmful bacteria, eliminating the need for preservatives.

5. Empty Calories

While Yakult contains 50 calories per bottle, around 40 of those calories come from sugar.

This means that Yakult primarily provides “empty calories” with little nutritional value beyond the probiotic bacteria.

How Many Bottles of Yakult Can You Consume Daily?

Yakult recommends consuming 1-2 bottles per day. However, due to the high sugar content, 1 bottle may be a safer daily limit for most people.

It’s essential to be mindful of portion sizes, especially if you have a sweet tooth. Children, in particular, may be tempted to consume more than the recommended amount due to Yakult’s pleasant taste.

Potential Side Effects of Yakult

While Yakult is generally considered safe, consuming too much can lead to some side effects:

  • Low immunity: Contrary to its claims, excessive Yakult consumption may weaken your immune system due to the high sugar intake.
  • Nausea and vomiting: Some people may experience digestive discomfort when introducing a new probiotic strain to their gut.
  • Stomach and digestive issues: Large amounts of Yakult may cause bloating, gas, or diarrhea, especially in those with sensitive stomachs.
  • Bloating: The introduction of new bacteria can temporarily cause bloating until your gut adjusts.

Who Should Avoid or Limit Yakult?

While Yakult is generally considered safe for most people, there are a few groups who should avoid or limit their consumption:

  • Diabetics: Due to the high sugar content, diabetics should avoid Yakult or opt for the “Light” version.
  • Children under 2 years old: Always consult a pediatrician before giving Yakult to young children. Yogurt may be a safer probiotic option for this age group.
  • People with lactose intolerance: Yakult contains milk-derived ingredients, so those with lactose intolerance should avoid it.

Pricing and Shelf Life

Yakult is a relatively budget-friendly option for introducing probiotics into your diet.

  • A pack of 5 bottles typically costs around Rs 70 (approximately $0.85 USD).

However, it’s essential to note that Yakult has a short shelf life of 10 days.

While you can still consume Yakult after 10 days, the probiotic bacteria may have died off, rendering it less effective.

Yakult vs. Yakult Light: Which One Should You Choose?

As mentioned earlier, Yakult also offers a “Light” version with reduced sugar content.

Here’s a quick comparison:

Nutrient Yakult Regular (per 65ml) Yakult Light (per 65ml)
Energy 50 calories 35 calories
Sugar 10g 3.5g

As you can see, Yakult Light contains significantly less sugar (3.5g compared to 10g in the regular version).

For those looking to limit their sugar intake, Yakult Light may be a better option. However, it’s worth noting that it still contains some added sugars.

The Importance of a Balanced Diet and Lifestyle

While probiotic drinks like Yakult can be beneficial, it’s crucial to remember that they are not a magic solution for gut health. A balanced diet and healthy lifestyle are equally important.

Here are some tips for improving your overall gut health:

  • Eat a fiber-rich diet: Fiber acts as fuel for the beneficial gut bacteria. Good sources include fruits, vegetables, whole grains, and legumes.
  • Stay hydrated: Adequate water intake supports healthy digestion and prevents constipation.
  • Exercise regularly: Physical activity improves blood flow and promotes healthy gut motility.
  • Manage stress: High stress levels can disrupt the gut-brain connection and contribute to digestive issues.
  • Get enough sleep: Sleep deprivation can negatively impact gut health and disrupt the balance of gut bacteria.

By combining probiotic foods like Yakult with a well-rounded diet and lifestyle, you can support your gut health and overall well-being.
