## Understanding everyday ingredients  

Yes, you already know that tomatoes are a fruit, botanically speaking, but food facts aren't just about getting a high score at the next pub quiz. They can actually help you in the kitchen as you learn the differences between ingredients and discover why some techniques and substitutions work while others fall flat.

If you're following a specific diet, like a low carb or [high protein meal plan](/food-box/high-protein-meals), food facts are particularly important. You'll need to learn the basics of different nutritional values, so you can plan your meals accordingly and reach for the best option when you're eating out.

Learning food facts means understanding why ingredients behave the way that they do, as well as how you can use them for success in the kitchen every time.

## How ingredients affect flavour, texture and cooking

Behind every ingredient that you use in your kitchen is a lot of science. You don't need to learn it all, but understanding the basics can be very helpful.

For example, you can consider the science behind baking. Flour provides structure to cake, bread and pastry. Kneading dough before you bake bread activates the gluten inside the flour, which becomes elastic, giving it a great texture when cooked. That's why attempting to just swap regular flour for gluten-free flour will fail.

Ingredients also behave differently depending on temperature. When you make pastry, you need to use very cold butter. The fat in the butter melts in the oven, producing small pockets of steam, which gives the pastry a light, flaky texture. Room temperature butter doesn't melt in the same way, so you won't get the same result.

## Ingredient insights and nutrition basics

Understanding [facts about salt](/stories/food-facts/types-of-salt), protein, carbohydrates and fat can help you follow a healthy, balanced diet. Don't worry — you don't need a degree in nutrition to grasp these simple concepts. The basics are easy to understand and can transform the way you approach meals.

### Nutrition basics, explained simply

All food is made up of three macronutrients (or macros): protein, fat and carbohydrates.

* **Protein** helps build and repair tissues and muscles.  
* **Fat** supports vital hormone health.  
* **Carbohydrates** provide the energy you need to get through the day.

Traditionally, most people tend to eat more carbohydrates and less protein and fat, but some choose to follow a low carb diet.

There are also micronutrients in food, including vitamins, minerals and fibre. All of these are necessary to keep the body healthy. For example, calcium is a mineral that promotes strong bones and teeth, while fibre keeps your digestive system working properly. You'll find calcium in dairy products like [Greek yoghurt](/stories/food-facts/why-greek-yoghurt), while fibre is common in many types of fruits and vegetables, as well as in wholegrain carbohydrates.

### Understanding ingredient labels and food types

Food producers are obliged by law to list nutrients on labels. This can help you make informed choices about what you eat.

* **Protein**: this is found in meat, eggs and fish. For plant-based alternatives, try tofu, tempeh, beans or lentils.
* **Carbohydrates**: rice, pasta, potatoes, bread and other starchy foods are full of carbohydrates. Choosing wholegrain options means you'll get more fibre and other micronutrients. 
* **Fats**: fat has often been demonised, but it's actually vital to keep your body functioning. As well as butter and oil, choose different [types of nuts](/stories/food-facts/types-of-nuts) or go for [duck recipes](/recipes/meat-recipes/duck).

Vitamins and minerals are often found in fruit and vegetables. Try eating the rainbow: different colours of fruit and veg have different micronutrients.

## Using food facts in everyday cooking

Understanding food facts can help you make better choices about what you eat. Sometimes it's easy. For example, you can quickly improve your diet by eating different colours of fruit and vegetables. 

* **Red** — tomatoes, strawberries and beets — is rich in lycopene.  
* **Orange** — carrots, sweet potatoes and oranges — is rich in beta-carotene for strong vision and clear skin.  
* **Dark green** — broccoli, spinach and kale — is rich in fibre and chlorophyll.

Use a variety of [fruit recipes](/recipes/fruit-recipes) to ensure you get enough of all these nutrients, or check out these [fruit facts](/stories/food-facts/types-of-fruit) for more information.

## Building confidence with food facts at home

Sometimes using food facts is as simple as swapping an ingredient for one that has more nutrients. For example, choose brown rice instead of white for more fibre. Sometimes it can be more complicated than that, especially if you're following a specific diet.

Either way, food facts are a great way to ensure you're eating the right thing. Next time you make your favourite Italian, Spanish or [Greek recipes](/recipes/greek-recipes), take a good look at the ingredients and see if you can understand exactly what's going into your body. That's the power of food facts\!

## Food facts FAQs

### What makes Greek yoghurt different from regular yoghurt?

Greek yoghurt has a higher protein content, which gives it a much thicker texture. This means it's the perfect choice if you're trying to get more protein into your diet — and it can be much more affordable than many meat options.

### Are nuts and seeds good for everyday cooking?

Nuts and seeds contain healthy fats, protein and a variety of micronutrients. They are high in fat, so keep that in mind if you're counting calories. A portion of about 30g is a good choice for everyday eating.

### What is the difference between types of salt used in cooking?

Table salt has very fine grains and often contains iodine. Sea salt has a coarser texture and has more mineral content; Himalayan pink salt is similar, but it has a very slightly different flavour and a distinctive colour.

### How can fruit be used beyond desserts?  

There are so many ways to use fruit in cooking. Roast pork and apple sauce is a classic, while South-East Asian cuisine often uses plums or pineapples in stir-fries and curries. Ripe fruit can also be added to salads.

### Why does ingredient knowledge matter in home cooking?  

Ingredient knowledge helps you make healthy choices and understand exactly what you are consuming. It allows you to substitute ingredients, for reasons of health, scarcity or personal taste, and enjoy a wide variety of meals.
