High Caloric Density and Weight Gain
Avocados are incredibly calorie-dense compared to other fruits. A single medium avocado contains roughly 240 to 300 calories and about 22 grams of fat. While these are “good fats,” consuming multiple avocados a day without adjusting the rest of your daily intake can easily lead to an unintentional calorie surplus and weight gain.
2. Gastrointestinal Distress (FODMAPs)
Avocados contain sorbitol, a type of sugar alcohol that falls under the category of FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols). If you have a sensitive gut or suffer from Irritable Bowel Syndrome (IBS), eating more than a small serving (about one-quarter of an avocado) can cause:
Bloating
Gas
Stomach cramps
Diarrhea
3. Latex-Fruit Syndrome (Allergic Reactions)
If you have a known allergy to natural rubber latex, you might experience a cross-reaction when eating avocados. This happens because the proteins in avocados are structurally similar to the allergy-inducing proteins found in latex. Symptoms can range from mild itching in the mouth and hives to severe stomach upset or anaphylaxis.
