Nutrition
The composition of an avocado comprises approximately 73% water, 15% fat, 8.5% carbohydrates (primarily in the form of fibers), and 2% protein.
A half of an avocado, weighing about 100 grams (g), provides 160 calories (1).
Carbs
In contrast to various fruits, avocados have minimal sugar content.
A half of an avocado, equivalent to 100 g, contains only 0.66 g of sugar, encompassing glucose, fructose, sucrose, and galactose.
The net digestible carbohydrates amount to just 1.8 g per 100 g of avocado.
Due to their low sugar content, avocados boast a remarkably low glycemic index score, indicating a limited impact on raising blood sugar levels (2).
Fiber
The majority of the carbohydrate content in avocados is comprised of fiber (79%).
For every 100 g serving of avocado, there is a notable 6.7 g of fiber, constituting a high amount that contributes to 24% of the daily value (DV).
Dietary fiber is a crucial element in the diet, offering numerous health advantages. It plays a role in appetite regulation, nourishing beneficial gut bacteria, and lowering the risk of various diseases such as heart disease, stroke, obesity, type 2 diabetes, and depression (3, 4, 5, 6).
Additionally, avocados contain FODMAPs (fermentable oligo-, di-, monosaccharides, and polyols), which are short-chain carbohydrates that some individuals may struggle to digest. While not everyone is sensitive to FODMAPs, they can trigger unpleasant digestive symptoms in those with irritable bowel syndrome (IBS).
To sum up, avocados are rich in fiber and low in sugar, but they do contain FODMAPs, which may lead to digestive discomfort in certain individuals. Explore more about the health benefits of dietary fiber and discover a list of 38 high-fiber foods here.
Fat
The avocado stands out as an uncommon fruit, serving as a significant reservoir of monounsaturated fatty acids, a beneficial type of dietary fat. Among these, oleic acid is the most abundant, mirroring its prominence in olive oil.
Studies have associated oleic acid with a reduction in inflammation and potential positive effects on cancer (7, 8). Avocado oil, being a noteworthy source of healthful fats, has demonstrated, through animal studies, potential protective effects against inflammation, heart disease, and diabetes (9, 10).
In summary, avocados, with their richness in monounsaturated fatty acids, particularly oleic acid, may contribute to protection against heart disease, diabetes, and cancer.

In summary, avocados abound in a variety of vitamins and minerals, including B-vitamins, vitamin K, vitamin E, vitamin C, potassium, and copper.
Other plant compounds
Here are the key plant compounds found in avocados:
- Carotenoids: Avocados are rich in carotenoids, including lutein and zeaxanthin, essential for eye health and potentially reducing the risk of age-related eye diseases (18).
- Persenones A and B: These unique antioxidants in avocados may provide protection against inflammation and cancer (19).
Due to their high fat content, avocados facilitate efficient absorption of the carotenoid antioxidants by the body (20).
In summary, avocados serve as a noteworthy source of various plant compounds, including carotenoids and antioxidants, with the high fat content enhancing the absorption of carotenoids by the body.
Benefits
Avocados are high in antioxidants and many important nutrients, some of which are rare in the modern diet.
For this reason, it is not surprising to see that avocados have numerous health benefits.
Heart health
Cardiovascular disease stands as the primary cause of global mortality (21).
Studies have established connections between heart disease risk and factors such as blood cholesterol, triglycerides, inflammatory markers, and blood pressure (22, 23).
Recent research indicates that incorporating avocados into the diet may lead to substantial reductions in blood cholesterol and triglyceride levels. Additionally, it has been observed to lower the potentially detrimental low-density lipoprotein (LDL) cholesterol while increasing the beneficial high-density lipoprotein (HDL) cholesterol (24, 25).

Satiety and weight loss
Some individuals on a calorie-restricted diet may believe that avocados should be avoided due to their elevated fat content.
However, including avocados in one’s diet doesn’t appear to hinder weight loss, and they can be consumed as part of a nutritious, calorie-controlled eating plan (26).
In fact, incorporating avocados into meals enhances the feeling of fullness, reducing the urge to eat for extended periods compared to a similar meal without avocados (27).
For this reason, avocados can be a valuable addition to an effective weight loss regimen.
Furthermore, avocados boast high fiber content, low carbohydrate levels, and do not cause spikes in blood sugar, making them a weight loss-friendly food.
Reducing symptoms of arthritis
Arthritis, marked by the gradual breakdown of joint cartilage, is prevalent in Western nations.
Derived from 33% avocado oil and 66% soybean oil, avocado and soybean unsaponifiables are supplements.
Various studies indicate that these supplements can alleviate arthritis symptoms, particularly in the knee and hip (28, 29).
In summary, avocados might lower cholesterol and triglyceride levels, significant risk factors for heart disease, and they also exhibit potential in alleviating symptoms of arthritis.
Risks
While avocados pose no issues for most individuals, they might trigger complications for those with allergies or irritable bowel syndrome (IBS).
Avocado allergy
While an allergy to avocados is uncommon, individuals with a latex allergy may encounter allergic reactions to certain fruits like avocados, bananas, or kiwis—a condition referred to as latex-fruit syndrome, as per an older study (30).
In latex-fruit syndrome, the immune system targets fruit proteins that resemble the allergy-triggering proteins found in latex. This can result in allergic reactions, ranging from digestive discomfort, stomach cramps, and headaches to more severe symptoms like anaphylaxis.
FODMAPs and IBS
FODMAPs can present challenges for individuals with IBS.
Consuming foods that contain FODMAPs may negatively impact digestion in these individuals, resulting in symptoms such as gas, cramping, bloating, stomach pain, diarrhea, or constipation.
For those experiencing digestive issues, closely monitoring symptoms after consuming avocados and other high FODMAP foods may be advisable.
In summary, while avocado allergies are rare, they may induce allergic reactions in individuals with a latex allergy. Additionally, avocados contain FODMAPs, which could prompt digestive symptoms in susceptible individuals.
Summary
Avocados are highly satisfying, exceptionally nutritious, and boast a delightful taste.
They serve as a rich source of various vitamins, minerals, and plant compounds, potentially offering advantages for heart health and arthritis.
Incorporating avocados into a wholesome diet is a commendable choice.
