Can You Put Yakult In Coffee? Answered

Yakult is a probiotic drink, and the combination of coffee and probiotics are often a hot topic in the news. So, can you put Yakult in coffee? Let’s find out!

Can You Put Yakult In Coffee
Simply putting Yakult in a hot cup of coffee may negate its health benefits

The heat and acidity from coffee can kill probiotics, which means that simply putting Yakult in a hot cup of coffee may negate its health benefits. I would not recommend mixing your probiotics into a hot drink, as it will defeat the purpose.

Researchers from the National University of Singapore developed a new fermented coffee beverage with more than one billion live bacteria.

The research team developed this probiotic coffee product as an alternative to dairy-based probiotic products. Many people consume coffee daily, making it an ideal base for probiotics that require daily supplementation. 

Probiotics and specific compounds in coffee can help stimulate bowel movement, but will the combination of probiotics and coffee upset your stomach or cause diarrhea? Starting a new probiotic routine may result in uncomfortable side effects, including gas or bloating.

Nevertheless, these side effects won’t last long – it is expected to clear up once your body gets used to the probiotics.

Should I Drink Yakult Before Or After Drinking Coffee?

We recommend taking your probiotic drink first thing in the morning or before you go to sleep, as this is the time when your stomach acid levels are least acidic.

Probiotics are most effective when you take them on an empty stomach – this ensures that the good bacteria reach your gut as quickly as possible, without any interruption from food or acidic drinks such as coffee.

For many people, drinking a cup of coffee is a daily ritual, but does it harm our daily dose of probiotics? With differing opinions everywhere, let’s try to clarify this by delving deeper into the matter.

As mentioned earlier, heat and acidity from coffee can kill most types of probiotic bacteria. Thus, I would not recommend mixing your probiotics with your hot cup of coffee or any other hot drinks.

You should also drink Yakult or any other probiotic drink one to two hours before or after drinking coffee. 

If you don't like coffee and prefer to start your day with tea, you may have heard that tea contains tannins, which can bind to minerals like iron and zinc and remove them from your body.

That’s why you should take these vitamins for at least 30 minutes before or after drinking your cup of tea. Nevertheless, this does not affect probiotics – the rules for drinking tea with probiotics are the same as for coffee. 

If you’re not a fan of hot drinks, you can drink water or juice. However, remember that probiotics don't like acid, so I wouldn't recommend mixing them with fruit juice. Water or milk is the best for bacteria. 

How Does Coffee Affect Probiotics?

Coffee or caffeine is not responsible for harming probiotics but the hot water

Coffee does not harm probiotic bacteria in general. However, if consumed immediately before or after drinking Yakult or any probiotic drink, hot coffee can kill probiotics. Many people don't realize that it's not coffee or caffeine that can harm probiotics – it's hot beverages or hot water.

As mentioned earlier, researchers from the National University of Singapore recently published data about this probiotic coffee product with over one billion units of probiotics!

Probiotic bacteria work by lining the gut and colonizing there to kill the harmful bacteria – that’s how it improves our overall health.

Probiotics help to:

  • Aid indigestion
  • Boost the immune system
  • Help the body produce vitamins such as biotin and vitamin B6
  • Increase vitamins and minerals absorption
  • Lessen cholesterol
  • Protect your intestines
  • Reduce cholesterol
  • Reduce depression
  • Reduce the growth of harmful bacteria
  • Reduce the risk of cancer
  • Regulate pH value
  • Slow down the growth of yeast in the body

Coffee contains acids, which can cause problems for some people, especially if left unchecked. 

Drinking too much coffee can lead to:

  • Adrenal gland burnout
  • Catabolic muscle breakdown
  • High cortisol levels
  • Insulin resistance
  • Nervous system stress

The recommended and healthy dosage of coffee is only three to four cups per day, around 400 mg of caffeine. 

What Interferes With Probiotics?

Probiotics will work wonders only if you have a balanced diet and a healthy lifestyle

Probiotics will not keep your digestive tract healthy on its own. Probiotics will work wonders with a balanced diet and a lifestyle change. So, before you start planning a healthy diet for a healthy gut, here's a list of foods to avoid as they can interfere with probiotics.

Processed Food

The packaged foods available in your local supermarket can interfere with your probiotics and gut system. Chips, cookies, cakes, and crackers are all processed foods high in preservatives and harmful ingredients that are bad for you and your gut.

So, what do these processed food do? They cause an imbalance between good and bad bacteria in your gut flora and destroy the healthy bacteria in your gut system. In addition, they have been stripped of fiber and have nothing to offer when it comes to nutritional value. 

If you want a healthy diet, the first thing that you should do is replace all kinds of processed and junk food with natural foods like fruits and vegetables.

Red Meat

Red meat can also interfere with your probiotics and gut health. Choline is a red meat nutrient that produces bad bacteria in the gut flora. These compounds can harden the arteries, which can result in heart issues.

Even eating red meat twice or three times a week can produce more harmful bacteria in your gut than healthy bacteria.

Carbonated Drinks

We all know how bad most carbonated beverages are for you. It's fine to have one or two every week, but going overboard with a regular consumption will only affect your health and digestive system.

If you think switching from regular to diet cola will help, you'll be disappointed to discover that diet-labeled beverages are just as harmful as the regular ones.

Carbonated drinks contain sugar substitutes – aspartame and sucralose – which have detrimental effects. Drinks with sugar and artificial sweeteners act as the source of food for bad bacteria in your gut system.

Gluten-Rich Foods

You may have come across various gluten-free diets while searching for a healthy diet. For people with coeliac disease, gluten is harmful. People acquire sensitivity to gluten-rich food’s components that cause an imbalance in the gut flora (more harmful bacteria, less good bacteria).

There is still no detailed study about gluten being harmful to human health, but it affects certain people, particularly those who consume more gluten-rich foods daily.

Refined Oils

Did you know that there are two types of oil; healthy and unhealthy. 

Canola, soybean, sunflower, corn, and safflower oil are all highly refined oils that can cause inflammation in your gut flora. These oils don’t even offer the essential omega-3 fatty acids, vital to the human body. They do nothing but cause damage to the lining of the intestine. 

It would be beneficial to use healthy oils such as olive, coconut, and avocado oil.

GMO Products

Genetically modified organism (GMO) products can also interfere with probiotics. Research has already proved its negative effect, although we still don’t have clear studies about how GMO food interferes with your digestive system. 

GMO food grows using herbicides, which can harm your gut system. Additionally, its genetic alteration also impairs the functions of healthy bacteria.

Don’t forget to read the package label first, as some companies use “GMO-free” on their packaging. However, relying on the product label isn’t enough; it’s still better to research GMO food products if you’re looking to clean your diet correctly.

To ensure that the probiotics work correctly, you can avoid these harmful foods.
