Q1. Which chef is widely credited with popularizing modern avocado toast in 1993?
- Yotam Ottolenghi
- Bill Granger in Sydney
- Gwyneth Paltrow
- Anthony Bourdain
Australian chef Bill Granger added smashed avocado on toast with lime, salt and pepper to the menu at Bills cafe in Sydney in 1993. It became the template for the global brunch dish.Q2. Botanically speaking, avocado is classified as a:
- Vegetable
- Single-seeded berry
- Nut
- Drupe
Avocado is technically a large single-seeded berry. The fleshy part surrounds a single big pit, which fits the botanical definition of a berry, even though it does not taste sweet.Q3. About what percentage of avocados eaten in the US come from Mexico?
- 20%
- 45%
- 75%
- Over 90%
Roughly 90%+ of avocados consumed in the United States are imported from Mexico, primarily from the state of Michoacán. California produces most of the rest, mainly the Hass variety.Q4. Most avocados sold worldwide are the Hass variety. Why?
- Cheapest to grow
- Buttery flavor and thick skin that ships well
- Largest size
- Naturally pest-resistant
The Hass cultivar originated from a single tree in California in the 1920s. Its high oil content, creamy flesh and pebbly thick skin make it durable for shipping. Most Hass avocados today still trace back genetically to that one tree.Q5. An average medium avocado contains roughly how many calories?
- 80 kcal
- 160 kcal
- 240 kcal
- 400 kcal
A medium avocado (about 150g of flesh) provides around 230-240 kcal, mostly from monounsaturated fat — the same heart-healthy fat that dominates olive oil.Q6. The healthy fat most abundant in avocado is:
- Saturated fat
- Oleic acid (monounsaturated)
- Omega-3 EPA
- Trans fat
About 70% of the fat in an avocado is monounsaturated, primarily oleic acid — the same type found in olive oil. It is associated with lower LDL cholesterol when it replaces saturated fat.Q7. Surprisingly, gram for gram, avocados contain MORE of which mineral than bananas?
- Iron
- Magnesium
- Potassium
- Calcium
Avocados contain about 485 mg of potassium per 100g, versus around 358 mg in bananas. They are quietly one of the best potassium sources, important for blood pressure regulation.Q8. What is guasacaca, sometimes called Venezuelan guacamole?
- A fried avocado dish
- An avocado-based sauce with vinegar and herbs
- A pickled avocado
- An avocado smoothie
Guasacaca is a Venezuelan sauce made by blending avocado with bell pepper, onion, garlic, cilantro, parsley, vinegar and oil. It is thinner and tangier than Mexican guacamole and used as a condiment.Q9. Why do avocados turn brown so quickly after being cut?
- Bacterial growth
- Oxidation of polyphenols by an enzyme
- Loss of water
- Reaction with light
When you cut an avocado, the enzyme polyphenol oxidase reacts with oxygen to oxidize phenolic compounds in the flesh, creating brown melanin-like pigments. Lemon juice slows this by lowering pH.Q10. Avocado farming has been criticized for which major sustainability issue?
- High water use and deforestation
- Excessive carbon from refrigeration alone
- Soil-borne contagious viruses
- Plastic packaging only
Avocado trees are thirsty — about 230 liters of water per fruit on average — and demand has driven illegal deforestation in parts of Michoacán, Mexico, where forests are cleared for orchards.
