This is why you should never drink a McDonald's Shamrock Shake

This is Why You Should Never Drink a McDonald’s Shamrock Shake

Updated February 21, 2018

St. Patrick’s Day is fast approaching, which means McDonald’s has released their annual green, minty and sweet “harbinger of Spring,” the annual McDonald’s Shamrock Shake.

Also known as The McCafe Shamrock Shake, the McDonald’s Shamrock Shake is a classic drink that has an almost cult-like following. Each year, thousands of people joyfully rekindle a love-affair with the McDonald’s minty February/March phenom known as the Shamrock Shake.

Shamrock Shake’s release date for 2018

Shamrock Shake Release

If you are a Shamrock Shake addict, I’ve got some intel for you. McDonald’s (participating locations) started rolling-out Shamrock Shakes on Thursday, February 22, 2018 and will continue through March.

Four new flavors for 2017

OooWee… excited? If yes, you will also be pumped to learn that MickeyD’s is releasing more than the original Shamrock Shake. This year (2017), for a limited time, there will be an entire line of Shamrock Shake flavors and varieties on the menu. Get all of the deets about this insanity by visiting my latest article,

Update: Missing in 2018 is the Shamrock Shake-related quartet unveiled in 2017. McDonald’s has decided NOT to release the Chocolate Shamrock Shake, the Shamrock Chocolate Chip FrappĂ©, the Shamrock Mocha and the Shamrock Hot Chocolate this year.

Nostalgic but not all that it seems

The Shamrock Shake evokes nostalgic feelings for many and since its introduction in the 1970s, over 60 million Shamrock Shakes have been sold. I credit McDonald’s marketing strategy – it’s rather brilliant. However, there’s more to this shake than what you can see.

One would think there are about 4 ingredients that make up the Shamrock Shake – ice cream, syrup, whipped cream and cherry, right? Well, yes… and no…. heavy emphasis on the no.

The truth, unraveled

This is why you should never drink a McDonald's Shamrock Shake

We all know that a sweet treat from McDonald’s is not going to be “healthy” by any means. Great… but do you know how unhealthy this particular indulgence, the McDonald’s Shamrock Shake, is? If not, hold onto your shakes, folks. I am about to reveal the truth of what is in this minty, sweet trip down memory lane.

It will then be up to you to decide whether or not you will continue drinking Shamrock Shakes. đź™‚ For everyone who has already decided that the cons outweigh the pros of this drink, keep reading, because I include healthy alternatives (complete with recipes) in this article.

The McDonald’s Shamrock Shake may be festive and fun, but it packs a punch. It is a fast-food calorie-bomb that consists of a staggering number of ingredients (35), many of which are obscure additives and dangerous chemicals. Let’s take a closer look:

Nutrition facts for McDonald’s Shamrock Shake (McCafe Shamrock Shake)*

A large, 22-ounce McDonald’s Shamrock Shake contains:

  • 820 calories
  • 200 calories from fat

This is why you should never drink a McDonald's Shamrock Shake

If your mind is blown by these nutrition facts, hold onto your skull because there is more. The ingredients that make up this creamy treat concern me more than its calories and fat content. The McDonald’s Shamrock Shake consists of 35 different ingredients! THIRTY-FIVE ingredients for a SHAKE.

I’d say that might be okay if those ingredients were straight-forward, natural and safe, but sadly, most are not. Many of these ingredients are artificial, chemical-heavy preservatives that wreak havoc on our health. Let’s take a closer look:

McDonald’s Shamrock Shake (McCafe Shamrock Shake) Ingredients

We all know that a dessert from McDonald’s is not nutritious, but many people are unaware of how unhealthy some of these menu items truly are. After a quick glance, the five ingredients of a Shamrock Shake look innocent.

These ingredients include:

  1. Vanilla reduced fat ice cream
  2. Shamrock Shake syrup
  3. Whipped topping
  4. Maraschino cherry
  5. Green sugar crystals (a new ingredient debuting in 2017)

However, upon closer inspection, each main ingredient has several ingredients of its own – and the majority are chemicals in the form of additives, food dyes and preservatives.

Yes, we and our environment are made up of chemicals, but I am talking about the chemicals that are not naturally found in whole foods – synthetic compounds that have been proven by science to be detrimental to our health.

Much of the food we consume (healthy and unhealthy) consists of more than one ingredient, but I want to emphasize that most of the main ingredients listed above have between 10 and 15 individual total ingredients, many of which are harmful to our health.

Here is the full breakdown of the ingredients in a McDonald’s Shamrock Shake:


  • Some ingredients such as sugar, high fructose corn syrup, carrageenan, and artificial flavors are repeated, which means that the final product has double and sometimes triple the amount of such ingredients. The ingredients which I have highlighted are linked to online resources.

Toxic cocktail

A “shake” should have four-to-six ingredients and less than ten in total, not 35. With the Shamrock Shake and its 35 ingredients, McDonald’s is serving up a chemical shit-storm that is full of artificial preservatives and colorings that are toxic to your body’s systems.

Many of the ingredients in this drink have been linked to various health issues and behavioral traits including:

“Every time you eat or drink, you are either feeding disease or fighting it.” – Heather Morgan, MS, NLC

Obviously, drinking one McDonald’s Shamrock Shake is not going to send you six-feet under right now, but its ingredients (refined sugar, saturated fat, trans fat, artificial dyes, additives and emulsifiers such as polysorbate-80) will very likely contribute to an inflammatory response within the body.

Inflammation often begins in your gut and affects multiple aspects of your health. If not managed, inflammation can lead to disease and illness later on in life, sometimes sooner than you would think.

Many of us have chronic systemic inflammation years before its symptoms become apparent or clinically significant. The shakes and lifestyle you choose now will impact your health in the future.

Dr. Francis Collins, director of the National Institutes of Health (NIH), once said that “genetics loads the gun, and environment pulls the trigger.” I strongly believe there is truth in this statement.

Knowledge is power

I want you to be educated on the food system and what “food” is on menus of places such as McDonald’s. Knowing what the ingredients are in the food you eat allows you the freedom to choose whether you will feed disease or fight it.

Numerous things we come into contact with daily (traditional Western Diet, sedentary lifestyle, non-organic meats and veggies, depression, anger, stress and anxiety, cigarettes, alcohol and pollution) already contribute to chronic inflammation within the body.

Why drink this chemical cocktail and add another trigger to the list? … and does a McDonald’s Shamrock Shake really taste THAT good?

Alternatives to the McDonald’s Shamrock Shake

If you are jonesing for a festive sweet-treat and care about your health, please stay away from McDonald’s and create your own Shamrock Shake. Here are three healthy alternatives:

1. Traditional homemade shamrock shake recipe 

Shamrock Shake Recipe - Bamboo Core FitnessIf you are craving a traditional homemade Shamrock Shake with ice cream and CAN tolerate cow dairy, visit my “Homemade Shamrock Shake” article for a perfect go-to milkshake recipe.

This cold, creamy and minty shamrock shake will not disappoint and is very simple to make at home. I say avoid the lines (and disappointment of broken shake machines at McD’s) and instead, make this at home.

It’s ingredients include:

  1. Organic vanilla ice cream
  2. Coconut milk
  3. Organic mint flavoring
  4. Fresh mint leaves
  5. Homemade coconut whipped cream (optional)


  • Allergic to cow’s milk? No problem. Substitute a store-bought or homemade dairy-free ice cream.
  • When buying the ingredients for this recipe:
    • Stick with organic whenever possible.
    • Avoid low-fat and no-fat ice cream and coconut milk – choose full-fat when possible.
    • Make sure the ice cream you buy does not contain unnatural preservatives, stabilizers, emulsifiers, or colors.
    • Choose a brand of ice cream with the least amount of ingredients. It should contain milk, cream, eggs, a sweetener like cane sugar, and vanilla bean. Nothing more.

The recipe

Note: This recipe is healthier than the McDonald’s Shamrock Shake, but is still high in sugar and calories. Remember – sugar and dairy contribute to inflammation. Also, be mindful of food allergies and intolerances.

2. Paleo and dairy-free homemade shamrock shake recipe #1

This Is Why You Should Never Drink A Shamrock Shake

If you are dairy-free, as many of my readers are, and want a shamrock shake version with less sugar than a traditional shamrock shake recipe, this recipe by The Healthy Beast may be a good choice.

It’s paleo and dairy-free and uses five to six main ingredients.

The main ingredients of the homemade shake include:

  1. Chilled coconut milk (coconut extract, water) 
  2. Banana
  3. Avocado
  4. Vanilla extract (vanilla beans extractives, water, alcohol)
  5. Peppermint extract (water, alcohol, peppermint oil)


  • The recipe calls for almond milk, but I suggest omitting this ingredient (unless you make your own almond milk) due to the additives found in many of the almond milk store brands. You can substitute a full-fat, organic coconut milk for the almond milk.
  • Buy as many ingredients organic as possible – especially the extracts.
  • If you want to avoid alcohol, or are sensitive to it, you can substitute fresh vanilla beans and mint leaves for the extracts.

Granted, if you are used to the sugary-sweet version from McDonald’s, this shamrock shake is going to be a far cry from what you are used to… however, it may be a good alternative for people looking to improve their diets – just be sure you are not allergic to the ingredients.

I have not made this version of the Shamrock Shake yet, but am looking forward to experimenting with it… hopefully the taste will be as good as the photos show it to be! 

The recipe

To see the complete recipe, visit the Healthy Beast: Shamrock Shake: 6 Ingredient Copycat (Dairy-Free, Paleo) Recipe

Note: Yes, the fat and calories from this shamrock shake recipe may be on the higher side of things due to the coconut milk and avocado, but I am not concerned with this because unlike that of the MickeyD’s version, coconut milk and avocado are healthier sources of fat. 

Consuming these whole foods (provided you are not allergic) will create a less dramatic blood sugar reaction within the body, help you feel more satiated (making you less likely to overeat), and will provide anti-inflammatory benefits (eating fresh, whole foods fights inflammation and prevents illness). Don’t forget to balance this healthy eating with an active lifestyle.

Huffington gets down with a Shamrock Shake infographic

The Huffington Post has created an infographic that provides more details about the McDonald’s Shamrock Shake. Click “Shamrock Shake: What’s Really In McDonald’s St. Paddy’s Day Drink?” to view the document more clearly.

Why You Should Never Drink A Shamrock Shake
Mmmm mmm mmmm.  After reading this information about the McDonald’s Shamrock Shake, are you still “loving it”…?!  I now for sure that I am not. Blah!

Frustration with the food industry

I am saddened and frustrated that our food industry is backwards in the sense that the health and wellbeing of Americans are NOT a priority. It is shocking that the Food and Drug Administration (FDA) allows this kind of crap to end up in consumers’ bellies.

Yes, people have the option to buy or not buy (and eat, or not eat) foods like this, but sadly, many people are not aware of the dangers that lurk in these “food-like-substances.”

Lack of transparency

This is why you should never drink a Shamrock Shake

Often, things aren’t as straightforward and transparent as they look. Large corporations like McDonald’s use tricky marketing ploys to suck people into their establishments.

Without the proper education about what’s in their foods, it can be rather confusing to navigate all of the nutritional information that is floating around us.

Become aware and take action

I write articles like this to enhance your awareness of restaurant (and fast-food) menu items so that you know what foods (or food-like substances) are lurking on your and your children’s plates.

I don’t think anyone should drink a toxic cocktail like this, but, in the end, it is up to YOU to decide what you will do with this information.

Get the word out

Knowledge is power. If you find any of this information appalling, surprising, useful and/or eye-opening, please help me spread awareness by sharing this knowledge with your friends, family and anyone else who will benefit… and skip the McDonald’s Shake this season.

Share this article on your social media sites, print and pass it out, talk about it at your dinner table and in your schools. Call and write to McDonald’s, demanding that they make changes to the nutrition and ingredients of their products!


Shamrock Shake RecipeJust say no to the McDonald’s Shamrock Shake (McCafe Shamrock Shake) this Saint Patrick’s Day. Instead, create a new tradition – quench your seasonal minty-green cravings with one of the homemade versions listed above instead.

    Thank you for sharing this awesome post. I’m filing
    it in my “Paleo Info” favorites folder so I can refer to it later (I can’t remmeber
    everything!) Just a question though, I’ve been doing paleo
    for about 4 days, I really need a change, lose some weight and start feeling better.

    I’ve got my paleo cookbook (my fav paleo cookbook) which I love
    (only about 13 bux) and have been using it every day so far but how long before I
    can expect to notice a change in weight and just general
    felling good?

  2. Moodie-1

    I was eating at a local Mickey D’s today with their pop art wall mural showing the names of all their stuff on the wall just in front of me. My eyes spotted the word “Shamrock Shake” on it and it occurred to me that I haven’t had one of these things for many, MANY years. So before walking out I ordered a small one, curious about what the public’s fascination with it was all about. I tried it in my car, expecting it to be pleasantly minty with a sidenote of vanilla. Well, was I disappointed! Aside from not being very minty at all I found it to be extremely sweet. Also, there was a pronounced other flavor, one I could not identify, that was just as (not) strong as the “mint” flavor. This made it quite unpalatable to me. After just a few unpleasant sips, I had to dump it. So much for that.

  3. Jen

    I agree with the moderation comment. Most people that I know feel constantly guilty if they eat something “not healthy”. And “not healthy” varies from person to person. Feeling like you have to apologize for what you eat or even hide what you eat so “healthy” eaters will not look down their noses at you. Food then because your master. So have a treat. Which is what a shamrock shake is. A treat. Arby’s mint shakes are better, so maybe have one of those instead.

  4. Shenanigans and Tomfoolery

    Maybe be a little more open about the studies and how they are linked to the conditions you listed? Many of the ingredients you list as concerns are often in these sorts of “splurgey, unhealthy” foods.

    Many of those conditions seem linked just as easily to eating too much unhealthy food. Not that these ingredients will immediately ‘kronenburg’ you irrevocably as this article tries to imply.

  5. Steve

    The old standby rule-of-thumb comes to mind, quite prominently, in fact;

    “EVERYTHING in moderation.”

    One or two 22 ounce Shamrock Shakes a year won’t hurt anyone!

  6. Michael Johnson

    When did America develop the taste for artificial chemicals? I quit MuckDonalds long ago simply because there are lots of better-tasting options out there. Maybe it has something to do with my lower chemical tolerance or the lack of actual food there. Don’t get me wrong, a double quarter pounder doesn’t sound too bad, but like I said, there’s no lack of better burgers in town, or even better, outside of town.

    1. Thanks for sharing your thoughts – you have made some great points. I think a challenging part of all of this is that a lot of the ingredients in these processed foods are addictive… and the food products have the allusion of being faster and easier/more convenient than whole, non-processed foods… and they are often cheaper… This opens the door for people to adopt habits and addictions to the foods that are sweetened and artificially flavored… and you’re right… your taste buds do have the capacity to develop the taste for artificial foods, just as they can develop to prefer healthier, cleaner foods too.
