Nutrients in a Balanced Diet

Extracts from this document...

Introduction

Nutrients in a Balanced Diet The 6 main nutrients are carbohydrates, fibre, vitamins, fats, protein and iron. Foods like cereals, bread, rice, pasta are good sources of carbohydrates and they give us the energy we need to do daily activities. If your daily calorie intake is 2,000 calories this amounts to at least 250 grams of carbohydrate per day. 1,500 calories a day equates to 188 grams of carbohydrate per day. Dried peas and beans like lentils, chickpeas and kidney beans are the best sources of fibre and is important for keeping the digestive tract working smoothly. Since we do not digest it, the fibre in food passes into the intestine and absorbs water. ...read more.

Middle

A lot of fat is hidden in foods that we eat, such as snacks, pastries or prepared meals. Fat is a nutrient that is an important source of calories. Fat is also needed to carry and store essential vitamins. The Department of Health recommends that no more than 30% of calories come from this nutrient, while most diets rarely recommend less than 20% of calories come from fat. Protein is found in foods that come from animals, such as fish, chicken, beef, pork, eggs, milk and cheese. It contains what is needed for cells to grow. It also repairs or replaces healthy cells and tissues. Protein in food also gives us calories. Someone weighing around 10 stone. ...read more.

Response to the question

Overall a good piece for GCSE level. The candidate shows a base understanding that is required for GCSE but to gain higher marks the candidate should grow into greater chemical detail and research the different nutrients better to gain a good understanding.

Level of analysis

The candidate outlines well why each nutrient is required and the guideline amounts of each, but the chemical knowledge required is only that of basic GCSE level. The candidate tries to analyse the dietary requirements in two practical situations and whilst their advice is correct to some degree, it is also wrong and shows the candidate needs further understanding of the role of the different nutrients

Quality of writing

There are some repetitions in the text and minor grammatical errors. Otherwise, spelling, punctuation and grammar are fine. The layout of the text is okay, but I think this should be split up into the different nutrients and their properties as for now this is all mashed together in one text.
