Food & Diet Vocabulary for IELTS — 30 Band-7+ Words with Examples
Food appears in almost every IELTS Speaking Part 1 (your favourite cuisine, eating habits, cooking at home), every other Part 2 cue card (a meal you enjoyed, a restaurant you'd recommend), and at least one Part 3 follow-up on the modern food industry. Writing Task 2 frequently sets prompts on obesity, fast food, sugar taxes, or vegetarianism. The 30 words below give you a balanced mix of everyday food language (cuisine, ingredient, processed) and the public-health and policy register (obesity epidemic, malnutrition, food security) that lifts a Speaking answer or essay from band 6 to band 7+.
IELTS prompts where this vocabulary fits
- Speaking Part 1: How important is breakfast in your daily routine?
- Speaking Part 3: Do you think the government should tax sugary drinks?
- Writing Task 2: Many people in modern societies follow unhealthy diets. What are the main causes and what can governments and individuals do about it?

Using these in IELTS Speaking
IELTS Speaking rewards natural production over recall. Aim to slip a higher-register word like cuisine or obesity into your answer at the moment the question invites it, rather than forcing a memorised phrase into the opening sentence. Examiners notice when vocabulary feels rehearsed.
If you are not sure of a collocation, use a slightly safer word you control. A single confident use of food waste in Part 3 — where the question explicitly invites discussion — gives examiners more evidence of range than a stilted opening sentence with three advanced terms.
Using these in IELTS Writing Task 2
Writing Task 2 rewards precise topic vocabulary in body paragraphs more than in the introduction. The introduction restates the prompt and signals your position; the body paragraphs are where examiners look for evidence of lexical range. Anchor each body paragraph on one main idea and weave in two or three words from this page that genuinely advance the argument.
Avoid the temptation to use every word on this page in a single essay. Two or three accurate uses of less common vocabulary is band-7 territory; five forced uses without natural collocation is a band-6 signal. Pair higher-register vocabulary with simple, grammatically clean sentences rather than the other way around.
Common traps to avoid
The most common food & diet trap at band 6.5 is collocation mismatch — using a word in a combination native speakers would not produce. The collocations column on the table above is the most important field for avoiding this; learn cuisine not as a single word but as part of the collocations listed beside it.
The second trap is register mismatch: using an informal word in a Writing Task 2 essay, or an overly formal word in a personal Speaking answer. The example sentences on this page are calibrated to the register IELTS expects for each section listed in the header.
