A healthy diet is essential for adults to maintain their weight and lower the risk of serious health conditions such as type 2 diabetes, certain cancers, heart disease and stroke. The number of calories an adult should consume depends on their sex, age, and physical activity level. According to the NHS, men should consume around 2,500 calories a day, while women should consume around 2,000 calories. A balanced diet includes fruits, vegetables, dairy, grains, and protein. The Mediterranean diet, for example, encourages the consumption of vegetables, fruits, whole grains, and healthy oils while limiting red meat and sweets. Adults should also limit their intake of saturated fats, trans fats, and added sugars, as these can increase the risk of obesity, heart disease, and other health issues.
| Characteristics | Values |
|---|---|
| Calories | The average person needs about 2,000 calories every day to maintain their weight, but the amount will depend on their age, sex, and physical activity level. Males tend to need more calories than females, and people who exercise need more calories than people who don’t. |
| Fat | Total fat should not exceed 30% of total energy intake. Intake of saturated fats should be less than 10% of total energy intake, and trans fats should be below 1%. Unsaturated fats are preferable to saturated and trans fats. |
| Sugar | Limiting intake of free sugars to less than 10% of total energy intake is part of a healthy diet. A further reduction to less than 5% of total energy intake is suggested for additional health benefits. |

What You'll Learn
Eat at least 5 portions of fruit and vegetables every day
Eating at least five portions of fruit and vegetables every day is an important part of a healthy, balanced diet for adults. This is because fruit and vegetables are a good source of vitamins, minerals and fibre, which are essential for maintaining good health and reducing the risk of disease.
Fruit and vegetables can be fresh, frozen, canned, dried or juiced, and they can be eaten at any time of the day. For example, you could have a glass of fruit juice or a smoothie with breakfast, a couple of pieces of fresh fruit as a snack, and a portion of vegetables with dinner. If you're struggling to get your five-a-day, you could also try having a dessert of plain, lower-fat yoghurt with fresh fruit.
It's important to note that only one portion of your five-a-day should be fruit juice or a smoothie. This is because, while these drinks are a convenient way to get one of your five portions, they are also high in sugar and can damage your teeth.
In addition to eating plenty of fruit and vegetables, adults should also aim to eat a variety of other foods to ensure they are getting a balanced diet. This includes starchy carbohydrates, such as potatoes, bread, rice, pasta and cereals, which should make up just over a third of the food you eat. When it comes to starchy foods, it's best to choose higher-fibre or wholegrain varieties, as these will help you feel full for longer and usually contain more vitamins and minerals.
It's also important to include some fat in your diet, but it's crucial to pay attention to the amount and type of fat you're consuming. Unsaturated fats, such as those found in vegetable oils, oily fish and avocados, are preferable to saturated fats, which are found in fatty meat, butter and cheese, as they can increase the risk of heart disease.

Consume starchy foods in moderation
Starchy foods should make up just over a third of everything you eat. This means that meals should be based on starchy foods. However, it is important to consume these foods in moderation. Starchy carbohydrates include potatoes, bread, rice, pasta, and cereals. When choosing starchy foods, opt for higher-fibre or whole-grain varieties such as wholewheat pasta, brown rice, or potatoes with their skins on. These foods contain more fibre than refined starchy carbohydrates and can help you feel full for longer. Fibre is essential for maintaining regular bowel movements and a healthy digestive system.
It is recommended to include at least one starchy food with each main meal. Some people believe that starchy foods are fattening, but gram for gram, the carbohydrates in these foods provide fewer than half the calories of fat. Therefore, starchy foods can be part of a healthy diet when consumed in moderation.
When it comes to fats, it is important to pay attention to the amount and type consumed. There are two main types of fat: saturated and unsaturated. Saturated fats are found in fatty meat, butter, palm and coconut oil, cream, cheese, ghee, and lard. Unsaturated fats, on the other hand, are found in fish, avocado, nuts, and sunflower, soybean, canola, and olive oils. While fat is essential for energy and cell health, consuming too much can lead to weight gain. It is recommended that total fat intake should not exceed 30% of total energy intake, with saturated fats making up less than 10% and trans fats less than 1%.
In addition to fat intake, it is important to limit consumption of free sugars to less than 10% of total energy intake. A further reduction to less than 5% can provide additional health benefits. Sugary foods and drinks are a major source of calories and can contribute to weight gain and tooth decay. Therefore, it is important to consume these in moderation or opt for sugar-free or low-sugar alternatives.
In conclusion, consuming starchy foods in moderation is an important part of a balanced diet. These foods provide essential carbohydrates and fibre, which contribute to a healthy digestive system and can help you feel full. However, it is important to be mindful of the amount and type of fat and sugar consumed in addition to starchy foods to maintain a healthy weight and overall well-being.

Include dairy or dairy alternatives
Dairy products, such as milk, cheese, and yoghurt, are good sources of protein and calcium, which helps keep your bones healthy. However, they can also be high in saturated fat, which can increase cholesterol levels and the risk of heart disease. Therefore, it is recommended to opt for lower-fat and lower-sugar dairy products where possible. For those who are lactose intolerant, vegan, or simply looking for alternatives, there are now many dairy-free options available, such as soy, almond, or oat milk. These alternatives are often fortified with calcium and other nutrients, making them excellent substitutes for cow's milk. However, it is important to read the labels carefully, as some may contain added sugars.
According to the NHS, adults should include some dairy or dairy alternatives in their diet. This can be in the form of milk, yoghurt, or cheese, which are all good sources of protein and calcium. Calcium is essential for maintaining strong and healthy bones, and dairy products are an excellent source of this mineral. For those who are lactose intolerant or prefer plant-based options, dairy alternatives such as soy milk, almond milk, or oat milk are excellent substitutes. These alternatives are usually fortified with calcium and other nutrients, ensuring that those who cannot or choose not to consume dairy can still obtain the necessary nutrients.
It is worth noting that while dairy products are a good source of protein and calcium, they can also be high in saturated fat. Excessive consumption of saturated fat can lead to increased cholesterol levels and a higher risk of heart disease. Therefore, it is important to opt for lower-fat dairy options when possible. Additionally, some dairy products can be high in sugar, so it is advisable to choose unsweetened or low-sugar alternatives. For example, plain yoghurt tends to have less sugar than flavoured varieties.
When choosing dairy alternatives, it is important to be mindful of the ingredients. Some dairy-free alternatives may contain added sugars or other additives. Reading the nutrition labels carefully can help you make an informed choice and ensure you select a product that aligns with your nutritional needs and preferences. Additionally, some dairy alternatives may not be fortified with calcium, so checking the calcium content is crucial, especially if you are relying on these alternatives to meet your calcium requirements.
In conclusion, including dairy or dairy alternatives in your diet is an essential component of a balanced diet. Dairy products offer protein and calcium, contributing to bone health, while alternatives provide similar benefits for those who cannot or choose not to consume dairy. However, it is important to be mindful of the fat and sugar content in these products and opt for lower-fat and lower-sugar options. Additionally, when choosing dairy alternatives, reading labels and ensuring adequate calcium fortification are key considerations. By including these options in your diet, you can ensure you are meeting your nutritional needs and maintaining your overall health.

Eat unsaturated fats in small amounts
A healthy diet for adults involves consuming a variety of foods in the right proportions to maintain a healthy body weight. While the number of calories required depends on one's sex, age, and activity level, the average person needs about 2,000 calories daily to maintain their weight. Men typically require more calories than women, and individuals who exercise regularly will need more calories than those who don't.
When it comes to fat consumption, it's important to note that some fat is essential in the diet. However, the type and amount of fat should be carefully considered. Unsaturated fats, found in foods like fish, avocado, nuts, and plant-based oils (sunflower, soybean, canola, and olive oils), are recommended over saturated fats and trans fats. Saturated fats, present in fatty meat, butter, palm and coconut oils, full-fat dairy products, and processed baked and fried foods, should be limited to less than 10% of total energy intake. Trans fats, both industrially produced (found in packaged snacks and cooking oils) and ruminant (found in meat and dairy from ruminant animals), should be kept below 1% of total energy intake. The goal is to shift towards unsaturated fats, as they promote healthy cholesterol levels, support brain health, and reduce inflammation.
To incorporate unsaturated fats into your diet, consider the following:
- Oils and Spreads: Opt for unsaturated oils like olive oil, canola oil, or sunflower oil instead of butter, lard, or ghee. Use these oils in small amounts as they are high in energy.
- Food Sources: Include foods rich in unsaturated fats, such as avocados, nuts, and oily fish like salmon, mackerel, and sardines.
- Moderation is Key: Remember that even though unsaturated fats are considered healthier, they still contribute a significant amount of energy (calories) to your diet. Therefore, consume them in moderation as part of a balanced diet.
- Read Labels: When purchasing products, read the nutrition labels to understand the fat content. Look for options with higher unsaturated fat content and lower saturated and trans-fat content.
- Cooking and Preparation: When cooking, use unsaturated oils, and try preparing foods using healthier methods like baking, grilling, or steaming instead of deep-frying.
- Mediterranean Diet: Consider the Mediterranean diet, which encourages the consumption of extra virgin olive oil (a source of unsaturated fat) while limiting red meat and sweets.
By incorporating these suggestions into your diet, you can increase your intake of unsaturated fats while maintaining a healthy balance. Remember to consult a healthcare professional or a dietitian for personalized advice based on your individual needs and preferences.

Limit salt and sugar intake
A healthy diet for adults involves eating a variety of foods in the right proportions to maintain a healthy body weight. While the number of calories each person needs depends on their sex, age, and activity level, most adults need to lose weight by reducing their calorie intake and being more active.
To maintain a healthy diet, it is important to limit salt and sugar intake. Firstly, eating too much salt can raise your blood pressure, increasing your risk of heart disease or stroke. The recommended daily intake of salt is less than 5 grams (equivalent to 2 grams of sodium) to help prevent hypertension and reduce the risk of heart disease and stroke. Salt intake can be reduced by opting for unsalted or low-salt versions of foods and avoiding the addition of salt when cooking or at the table.
Sugar intake should also be limited as regularly consuming foods and drinks high in sugar increases the risk of obesity and tooth decay. Free sugar intake should be less than 10% of total energy intake, with a further reduction to less than 5% suggested for additional health benefits. To reduce sugar intake, it is recommended to limit the consumption of sugary drinks, sweets, and processed foods, and to read labels carefully when choosing dairy alternatives as some contain added sugar.
In addition to limiting salt and sugar, a healthy diet includes eating at least 5 portions of fruit and vegetables every day, choosing higher fibre and wholegrain starchy foods, consuming dairy or dairy alternatives, and eating beans, pulses, fish, eggs, meat, and other sources of protein. It is also important to pay attention to the amount and type of fat in the diet, with unsaturated fats being preferable to saturated fats and trans fats.
