Healthy Eating Foundations
What a balanced diet actually looks like, how to build a plate, and how to make healthy eating realistic rather than restrictive.
LANGTONS PRACTICAL COACHING GUIDE
Healthy Eating Foundations: what matters most
Good nutrition is built on patterns you can repeat, not perfect meals. A varied diet provides energy, protein, fibre, vitamins and minerals. Start with the overall pattern, then adjust portions and meal timing for your appetite, activity and goals.
1. Build a balanced plate
For a practical lunch or dinner, begin with plenty of vegetables, add a protein source, include wholegrain or higher-fibre carbohydrate and a modest amount of unsaturated fat. This is a visual planning tool, not an official NHS percentage rule: portions should change with energy needs and activity. Over the whole day and week, follow the NHS Eatwell Guide, which emphasises fruit and vegetables, starchy carbohydrates (preferably higher fibre), protein foods, dairy or alternatives and small amounts of unsaturated oils [1].
2. How much fruit, vegetables and fibre?
Aim for at least five portions of varied fruit and vegetables daily; one adult portion is generally 80 g of fresh, frozen or canned produce [2]. Adults are advised to consume around 30 g of fibre daily [3]. Increase fibre gradually and drink enough fluid, especially if your current intake is low.
Useful swaps include oats instead of low-fibre cereal, wholegrain bread, lentils added to mince, fruit instead of a low-fibre snack and vegetables at both lunch and dinner.
3. Choose fats and carbohydrates intelligently
Carbohydrates are useful fuel, especially when you train. Choose oats, potatoes, rice, wholegrains, beans and fruit most often; the right portion depends on activity. For fats, favour olive or rapeseed oil, nuts, seeds and oily fish over frequent large amounts of foods high in saturated fat [1, 4]. You do not need to eliminate bread, pasta or dietary fat to eat well.
4. Salt, sugar and hydration
The NHS recommends adults have no more than 6 g of salt per day [5]. Most salt comes from prepared foods rather than what you add at the table. Free sugars should make up no more than 5% of total energy intake, with a general adult maximum of about 30 g per day [6]. Water, milk and unsweetened drinks can all contribute to hydration; use thirst and urine colour as everyday cues, with extra fluid during hot or prolonged exercise.
5. Make it sustainable
Plan two or three reliable breakfasts and lunches, keep frozen vegetables and canned beans available, and cook an extra portion for tomorrow. Look at the week, not one meal. Eating out and favourite foods can fit into a healthy pattern; rigid rules often make consistency harder.

Common questions
Are carbohydrates unhealthy?
No. Type, quantity and overall dietary pattern matter more than avoiding carbohydrates.
Do I need supplements?
Most people can meet basic nutritional needs through food; specific supplements may be appropriate in certain circumstances. NHS guidance recommends considering vitamin D supplementation during autumn and winter [7].
