Like most superheroes in the culinary universe, the avocado brings a bunch of health benefits to the table (14). It’s full of healthy fats, packed with vitamins and minerals, and is a heart-friendly choice that’s hard to resist.

It adds creaminess to your salads, gives your smoothies a health kick, and even makes a decadent toast topping.

Before you take another scoop of that delicious dip, read on to discover the eight potential avocado side effects that might make you rethink your love for guacamole.

What Are Avocado’s Side Effects?

The side effects of eating avocado every day include; potential high calorie intake, weight gain, and risks for those with latex allergy. Additionally, avocado contains Tryamine, an amino acid that can induce migraines for some individuals, although the evidence is still inconclusive.

High Calorie Intake

Avocados may be a healthy addition to your diet, but it’s crucial to keep in mind that they are high in calories. One medium-sized avocado packs around 240 calories (4), and most people tend to eat more than that in one sitting, especially in the form of guacamole.

A calorie-dense diet is linked to a higher risk of (11):

  • Type 2 diabetes – when the body becomes resistant to insulin or doesn’t produce enough of it, leading to high sugar levels in the blood.

  • Coronary heart disease – when plaque builds up in the arteries, leading to a higher risk of heart attacks and strokes.

Avocado Intolerance

Avocado intolerance is a condition where you experience negative reactions after consuming avocado (e). Unlike allergies, which are caused by your immune system, intolerance is a digestive issue. It occurs when your body has difficulty digesting. 

The exact cause of avocado intolerance is not fully understood. However, experts believe that it could be linked to an inability of the body to produce enough enzymes needed for proper digestion.

The symptoms of avocado intolerance or allergy may include:

  • Itching
  • Hives
  • Swelling of the lips, tongue, or throat
  • Difficulty breathing
  • Stomach pain or vomiting

Risks for Those with Latex Allergy

Avocado contains a protein called chitinase, which can cause an allergic reaction in individuals with a latex allergy (15). This is known as cross-reactivity, where the proteins in avocados are similar to those found in latex, and the body may mistake them for the same substance.

Symptoms of this allergy can range from mild reactions like itching or hives to more severe complications such as difficulty breathing or anaphylaxis. If you have a latex allergy, it’s essential to speak to your doctor before adding avocados to your diet.


Avocado contains Tryamine, an amino acid that is believed to trigger headaches or migraines in certain individuals (7). However, the evidence for this is still inconclusive and varies from person to person. 

If you’re prone to migraines or have a family history of them, it’s best to keep track of your avocado intake and consult with a doctor if they seem to be triggering headaches.

Blood Pressure Concerns

Tryamine is not only linked to migraines but it’s also known for its ability to raise blood pressure levels (17). Therefore, individuals with high blood pressure should consume avocados in moderation.

Furthermore, avocados have a high potassium content, which can also contribute to an increase in blood pressure if consumed excessively (12).

For people on medication to control their blood pressure, it’s essential to consult with a doctor before adding avocados to their diet.

Gastrointestinal Issues

If you eat too much of it, side effects include gastrointestinal issues like bloating, gas, and stomach discomfort (16). This is because of the high fiber content in avocados, which can be difficult for some people to digest. 

Additionally, if you have a sensitive stomach or suffer from irritable bowel syndrome (IBS), it’s best to limit your avocado intake to avoid any discomfort.

Side Effects of Avocado Seed

According to the California Avocado Commission, there is not enough research to support consuming the seed (l). 

While it’s known that the seed contains a number of nutrients and antioxidants, it’s unclear whether these substances are bioavailable (able to be absorbed and used by the body).

The seed also contains tannins, substances that can contribute to a bitter taste and may cause an upset stomach in some individuals (13). 

Most experts recommend sticking with eating the flesh of the avocado, which is well-known for its health benefits (10).

We provide detailed information on the pros of avocado consumption in our previous post – Avocado Benefits For Men.

Avocado Seed Tea Side Effects

One way we can consume avocado seeds is by making tea out of them. However, there is not enough research to support this practice, and some experts caution against it due to the potential side effects.

Since avocado seeds contain tannins and other compounds that may cause gastrointestinal issues, consuming large quantities of seed tea can cause digestive problems like bloating, gas, and stomach pain. 

Additionally, avocado seed tea may interact with certain medications, so it’s essential to consult with a doctor before trying it (6).

How Much Avocado Is Too Much?

One way to get avocado’s health benefits without risking any side effects is to consume it in moderation.

According to the California Avocado Commission, one serving of avocado is about ⅓ of a medium-sized fruit, which contains around 80 calories (5). 

It’s recommended to consume no more than two servings of avocados per day to avoid consuming too many calories and potential side effects.

Is It Unhealthy To Eat An Avocado Every Day?

Yes, it may be unhealthy to eat an avocado every day, especially if you’re consuming it in excessive amounts.

Before eating an avocado a day, ask yourself:

What Is My Daily Calorie Allowance?

Assuming you’re not trying to gain weight, the recommended daily calorie intake for adults is around 2,000-2,500 calories a day (9). This may vary depending on your age, gender, and activity level.

If you consume an avocado every day without taking into account your other food choices and calorie intake, it’s easy to exceed your daily limit and risk potential side effects like weight gain, gastrointestinal issues, and blood pressure concerns.

Therefore, it’s important to track your avocado intake along with other foods you consume.

Am I Getting Enough Variety In My Diet?

Eating an avocado every day may also limit the variety in your diet. While avocados are incredibly nutritious, they do not provide all the essential nutrients and vitamins needed for a balanced diet. 

It’s important to incorporate a variety of fruits, vegetables, whole grains, proteins, and healthy fats into your meals to ensure you’re getting all the nutrients you need.

  • You have a latex allergy
  • You’re taking medication for blood pressure control
  • You experience migraines or headaches after consuming avocados
  • You have gastrointestinal issues like diarrhea, bloating, or stomach pain

I've struggled to maintain programs…

I've struggled to maintain programs before, but somehow I've been able to stick with this. I enjoy the workouts and have made healthy changes to my diet with the challenges. Its nice for something to really have stuck and worked. I did the sugar free challenge and it's really changed how I relate to the signals my body is giving me about the food I'm eating.

Our Journey

This has been an awesome journey for my wife and I. Not only are we losing weight , but we are living a new life style. Our eating habits have been reformed by following the meal plan and our bodies have become stronger by simply doing the ten minute, sometimes twenty minute workouts. It really has been easy and convenient to transition into a healthier routine and has truly re energized our lives moving forward into the future.

It Works! This program is working for me!

lynne R.
This program is working for me! After a little over a month, I have lost 10 pounds. Slow, but steady. Guided exercises are done daily and there is an option to do other routines beside the one chosen for the day. It is very helpful having the recipes for all meals plus a snack. Would like if we could know the ingredients the day before. Makes preparing alot easier. I like the fact that alternative foods are suggested in case you can't eat(or don't like) the recipes listed. This is a very good program. Stick to it and YOU will see results. I have!
