Is smoothies good for acid reflux?

Quick Answers

Smoothies can be good or bad for acid reflux depending on the ingredients used. Some ingredients like citrus fruits, tomatoes, chocolate, and caffeine can trigger acid reflux. However, smoothies made with ingredients like bananas, almond milk, spinach, avocado, and ginger can help reduce symptoms. The key is choosing low acid, non-irritating ingredients. Smoothies allow you to control ingredients so they can be customized to help or avoid triggering reflux.

What is Acid Reflux?

Acid reflux, also called gastroesophageal reflux disease (GERD), is a condition where stomach acid frequently flows back up into the esophagus. This backwash of acid causes irritation, inflammation, and pain known as heartburn.

When you swallow, a band of muscle around the bottom of your esophagus (lower esophageal sphincter) relaxes to allow food and liquid to flow down into your stomach. Then it tightens again to prevent contents from leaking back up.

With acid reflux, this muscle becomes weak or relaxes inappropriately. The stomach acids can then reflux up into the esophagus, causing burning sensations, nausea, bloating, coughing, hoarseness, and other symptoms.

Some factors that can trigger or worsen acid reflux include:

– Eating large, heavy meals
– Lying down too soon after eating
– Being overweight or obese
– Eating trigger foods like citrus, tomatoes, spices, chocolate, caffeine, alcohol, etc.
– Smoking cigarettes
– Pregnancy
– Hiatal hernia
– Certain medications

Acid reflux causes uncomfortable symptoms and complications like esophageal damage, so it’s important to avoid triggers and manage it properly. This is where smoothies can help.

Are Smoothies Good for Acid Reflux?

Smoothies can be a great dietary option for managing acid reflux symptoms. When made with the right ingredients, smoothies provide nutrition and hydration without irritating the esophagus.

There are several potential benefits of smoothies for acid reflux:

1. Smooth Texture

Smoothies have a thick, smooth texture that can help prevent reflux. Liquids are able to pass through the esophageal sphincter quickly and easily. Thicker smoothies move more slowly, so they are less likely to reflux back up.

2. Hydration

Staying hydrated is important for managing acid reflux. Smoothies provide fluid without filling the stomach too much. Dehydration can increase risk of acid reflux symptoms.

3. Nutrition

Smoothies allow you to pack in servings of vegetables, fruits, protein, healthy fats, etc. Proper nutrition aids digestion and can improve overall gut health.

4. Low Fat

Smoothies made with non-dairy milks and without added sugary ingredients are naturally low in fat. High fat foods can exacerbate reflux, so smoothies are less likely to cause symptoms.

5. Portion Control

You can control the portion size of smoothies, unlike juices which are often quickly consumed in large amounts. Smaller portions are gentler on the stomach.

6. Avoiding Triggers

The ingredients in smoothies can be tailored to prevent acid reflux triggers. Citrus fruits, spices, chocolate, etc. can be left out.

So in general, smoothies can be a good option for managing acid reflux symptoms. But the specific ingredients matter greatly.

Smoothie Ingredients to Avoid with Acid Reflux

While smoothies are often great for acid reflux, ingredients matter. Some items commonly used in smoothies can trigger or worsen symptoms:

Citrus Fruits

Citrus fruits like oranges, grapefruit, lemons, and limes contain acids that can irritate the esophageal lining and sphincter. The natural acids in citrus can provoke reflux symptoms.


Like citrus fruits, tomatoes are naturally acidic which can burn the throat and esophagus. Raw tomatoes are especially problematic.


Spicy seasonings like chili powder, cayenne, and hot sauce contain capsicum that can inflame the esophagus. Even small amounts of spices in smoothies may provoke symptoms.


Chocolate contains caffeine and cocoa, both of which are common acid reflux triggers. Chocolate smoothies are best avoided.

Carbonated Beverages

Fizzy drinks like soda contain carbonation that can cause belching and reflux. The bubbles expand in the stomach, pushing contents back up.


Like soda, coffee contains caffeine which relaxes the esophageal sphincter. This allows increased reflux of stomach acid. Decaf coffee may also be problematic.


Alcohol consumption is a risk factor for acid reflux. Even small amounts of alcohol like wine, beer, or spirits can relax the sphincter muscle and provoke symptoms.


Peppermint and spearmint may seem soothing, but mint may promote acid reflux in some people. It may lower esophageal sphincter pressure.

Fatty Foods

High fat ingredients like cream, oil, nut butters, coconut milk, and avocado slow digestion. This can trigger reflux in some cases. Minimal amounts are okay.

So avoiding these triggers when making smoothies can prevent acid reflux flare-ups.

Best Smoothie Ingredients for Acid Reflux

Focusing on low acid, non-irritating ingredients is key to constructing reflux-friendly smoothies. Some of the best ingredients to reduce symptoms include:

Non-Dairy Milks

Non-dairy milks like almond, soy, oat, hemp, flax, and coconut are smoothie bases that are low fat and usually do not aggravate reflux.


Ripe bananas are a smoothie superfood for acid reflux. They are naturally low in acidity and coat the esophagus to reduce irritation from stomach acid.


Watermelon, cantaloupe, honeydew and other melons are hydrating fruits that are low in acid. Melons are unlikely to trigger reflux.


Oats thicken smoothies naturally while providing fiber. This can help prevent reflux. They also contain soluble fiber which soothes the GI tract.

Leafy Greens

Greens like spinach, kale, and swiss chard provide nutrients and make smoothies thicker. The chlorophyll may also reduce inflammation.


Fennel has antispasmodic effects that help relax the muscles around the esophagus and promote healthy digestion.


Ginger root has anti-inflammatory effects that can help reduce irritation in the esophagus caused by acid reflux. It also aids digestion.

Fruit Juices

Small amounts of low-acid juices like apple, grape, pear, or aloe vera juice can provide flavor and nutrients without aggravating reflux.

Focusing on these types of real, whole ingredients can allow you to construct satisfying smoothies that minimize acid reflux discomfort.
