TASC Food and Nutrition Level 3 common mistakes
TASC Food and Nutrition Level 3 · Understand the traps and how to avoid them.
Describing nutrients only by the food group they come from (e.g. 'calcium is in dairy') instead of naming the nutrient's function and deficiency consequence when asked to explain nutritional role.
Candidates memorise food-group charts rather than nutrient functions, so they recycle the same label for every nutrient question and lose marks on the 'why it matters' component.
What to do instead
Build a one-page nutrient table with four columns per nutrient: function in the body, deficiency symptom, key food sources, and one at-risk group. Practise writing a two-sentence explanation for each nutrient using all four columns before checking the mark scheme.
Treating the Eatwell-style balance guidance as a rigid percentage rule for every individual, ignoring age, life stage, activity level, and medical conditions.
Revision guides present population-level proportions as universal laws, and candidates rarely practise applying guidance to a named individual.
What to do instead
For each life stage (toddler, teenager, pregnant woman, older adult, athlete) write one paragraph stating which guidance stays the same and which changes, with the reason. Practise questions that begin 'A 78-year-old with low appetite...' and always state the modifying factor explicitly.
Confusing food safety hazard types, labelling a chemical hazard as biological or vice versa, and omitting the control measure that matches the hazard.
Candidates learn a list of hazards without pairing each to its control, so under exam pressure they guess the category and write a generic 'be careful' control.
What to do instead
Make a three-column chart (hazard type, example, specific control) covering biological, chemical, physical, and allergenic hazards. For each example, state the control as a measurable action, e.g. 'chill to 0-5 degrees Celsius within 90 minutes', not 'keep cold'.
Writing research aims that are vague or double-barrelled, such as 'to find out about sugar and health', instead of a focused, measurable aim with a defined population and outcome.
Candidates draft the aim quickly to get to the 'interesting' part of the task and do not test whether the aim can actually be answered with the data they plan to collect.
What to do instead
Use a template: 'To investigate the effect of [one variable] on [one measurable outcome] among [defined group] over [timeframe].' Draft three aims, then reject any that contain 'and' joining two variables or that cannot be measured with the proposed method.
Presenting secondary research data without evaluating its source, date, sample size, or commercial interest, and citing a blog or supermarket leaflet as equivalent to a peer-reviewed study.
Candidates equate 'found online' with 'researched' and have not been taught to apply a credibility checklist to nutrition information.
What to do instead
Apply a five-point source check to every source used: author qualification, publication date, sample size, funding or commercial interest, and whether it is primary or secondary. Record the check in a table and state in the write-up which sources passed and which were excluded and why.
Reporting results as raw counts only (e.g. '12 people preferred the smoothie') without calculating percentages, means, or comparing against the sample size.
Candidates collect data but have limited confidence with numeracy, so they stop at tallying rather than analysing.
What to do instead
For every data set, produce three outputs before writing conclusions: the raw count, the percentage of the sample, and the mean or range where relevant. Practise converting a tally table into two sentences that state the finding and its size relative to the sample.
Describing a practical food preparation method step by step without explaining the food science reason for each step, such as why resting meat or creaming butter matters.
Candidates rehearse the 'doing' of the practical and treat the written explanation as a recount of actions rather than an explanation of processes.
What to do instead
After each practical, write a 'because' line for every key step, linking to a principle such as gluten development, emulsification, gelatinisation, or protein denaturation. Aim for one scientific reason per step and check that no step is left as description only.
Ignoring cross-contamination and critical control points when planning a practical, mentioning hygiene only as a closing sentence.
Hygiene is taught as a separate topic, so candidates do not integrate it into the sequence of a practical plan where the risk actually occurs.
What to do instead
Annotate the practical plan itself with control points at each stage: storage on arrival, separate boards for raw and ready-to-eat items, cooking temperature, cooling time, and holding temperature. Each annotation must name the hazard being controlled.
Making a recommendation without weighing trade-offs, such as advising a cheaper menu option without acknowledging its lower micronutrient density or higher salt content.
Candidates see decision-making as picking a winner rather than balancing competing criteria, and exam prompts reward explicit weighing.
What to do instead
Use a decision matrix with at least four criteria (cost, nutritional quality, seasonality or sustainability, practical feasibility), score each option, then write a paragraph naming the strongest trade-off and justifying the final choice.
Evaluating a dish or menu with vague adjectives ('tasty', 'healthy', 'nice texture') instead of sensory and nutritional criteria that could be measured or observed.
Everyday food language is evaluative but imprecise, and candidates have not practised converting opinions into assessable criteria.
What to do instead
Before evaluating, write the criteria first: appearance, aroma, flavour, texture, and nutritional contribution, each with a descriptor scale. Then write the judgement using those descriptors plus at least one nutritional measure such as energy or salt per portion, and state one specific improvement with its justification.
