19. Mayonnaise

Mayonnaise is a common condiment, but it’s shockingly high in fat and calories. Made primarily from oil, egg yolks, and vinegar or lemon juice, a single tablespoon can contain around 100 calories and 11 grams of fat. Many store-bought versions also contain preservatives and artificial flavors.
Why You Should Avoid It
The high fat content in mayonnaise can contribute to weight gain and high cholesterol levels. The preservatives and artificial additives don’t do your health any favors either. Opt for healthier alternatives like Greek yogurt or avocado spreads to cut down on unhealthy fats.
