Food and diet: IELTS Speaking Part 3 questions

Last updated 21 July 2026

In short

Food and diet is a common IELTS Speaking Part 3 discussion theme. After the Part 2 long turn, the examiner explores broader, abstract questions on the topic. This guide groups real practice questions from concrete to abstract, explains how to tackle each question type, and gives the vocabulary and linking language to answer with depth.

Discussion questions

The examiner usually opens the discussion with: "What kinds of food are most popular with people in your country?" — then works up from concrete to abstract.

Warm-up (concrete)

Why do you think fast food has become so common?
Cause & effect

Development (societal)

How have people's eating habits changed compared with the past?
Comparison
Do you think it is important for families to eat together?
Opinion
What are the advantages and disadvantages of eating out often?
Evaluation
Should schools be responsible for teaching children about healthy eating?
Opinion

Depth (abstract & hypothetical)

How might the way people eat change in the next few decades?
Speculation
If healthy food were cheaper than unhealthy food, would people's diets improve?
Hypothesis
Is traditional home cooking being lost in modern life?
Evaluation

How to answer each question type

Part 3 mixes several question functions. Recognise which one you're facing and structure your answer to match.

Cause & effect questions

Asks why something happens or what its consequences are.

Name the cause or effect first, then explain the chain of reasoning step by step. Causal linkers signal clear logic to the examiner.

Comparison questions

Asks how two things — often past vs. present, or two groups — differ.

Make the two things explicit, then compare on one or two clear dimensions rather than listing everything. Comparative structures show grammatical range.

Opinion questions

Asks what you think about an issue. Tests whether you can state and defend a position.

State your view clearly in the first sentence, give one or two reasons, then support each with a concrete example. Avoid sitting on the fence.

Evaluation questions

Asks you to weigh advantages and disadvantages, or judge how good/important something is.

Acknowledge both sides briefly, then come down on one. Use contrast markers to show you can balance ideas before reaching a judgement.

Speculation questions

Asks you to predict the future or imagine how things might develop.

Use modal verbs to hedge (might, could, is likely to) and give a reasoned prediction — the grammar of uncertainty is exactly what's being tested here.

It's likely thatI imagineIn the long run,We may well see

Hypothesis questions

Asks you to reason about an unreal or 'what if' situation.

Reach for the conditional (if + past, would). Set up the scenario, then follow the consequence through — this shows control of higher-level structures.

If that happened,SupposingIn that case, I'd expectWere that the case,

Linking language for discussion

Frequently asked questions

What kind of questions come up in IELTS Speaking Part 3 about food and diet?

Part 3 questions are abstract and opinion-based. You'll be asked to give views, compare past and present, weigh advantages and disadvantages, explain causes and effects, and speculate about the future — rather than talk about yourself.

How long should my Part 3 answers be?

Longer than in Part 1 — aim for three to five sentences. State your point, give a reason, and back it up with an example. Part 3 is where you demonstrate range and depth.

How is Part 3 different from Part 2?

Part 2 is a personal monologue; Part 3 is a two-way discussion of the wider issues linked to that topic, so the language becomes more abstract and analytical.
