People with the healthiest diets tend to follow a few basic principles, such as eating plenty of fruits and vegetables, opting for whole foods over processed options, and choosing healthy fats like olive oil. They also consume adequate protein from plant-based or animal sources and ensure their meals are balanced with carbohydrates, fats, and proteins. Portion control is another important aspect, with an emphasis on eating until 80% full and sharing meals with others. These individuals are likely to have a lower risk of chronic diseases and may experience improved overall health and longevity.

What You'll Learn
Eat at least 5 portions of fruit and vegetables a day
Eating at least five portions of fruits and vegetables a day is essential for maintaining a healthy diet and preventing malnutrition. This daily intake provides significant health benefits, including reducing the risk of serious health problems such as heart disease, stroke, and certain types of cancer.
Fruits and vegetables are excellent sources of vitamins, minerals, and dietary fibre, which are necessary for optimal health. For example, they contain folate, vitamin C, and potassium, which help to maintain a healthy gut and prevent digestion problems. By including a variety of colourful fruits and vegetables in your diet, you can benefit from a diverse range of nutrients.
To ensure you get your five-a-day, aim for a mix of two servings of fruit and three servings of vegetables. This combination has been associated with the greatest longevity. A serving of fruit or vegetables is typically about 80 grams, which is roughly the amount that fits in the palm of your hand. For example, a serving of fruit could be two small fruits, like plums or kiwis, or one larger piece, like an apple or banana.
When it comes to vegetables, a serving could be two broccoli spears, two heaped tablespoons of cooked spinach, or three heaped tablespoons of cooked carrots. Beans and pulses are also a great option, but remember that they only count for a maximum of one portion of your five-a-day. It's important to note that starchy foods like potatoes, yams, and cassava don't count towards your five-a-day, but they do provide essential nutrients and should be included in your diet.
By incorporating a variety of fruits and vegetables into your diet, you can not only improve your health but also add flavour and colour to your meals. Whether they are fresh, frozen, canned, dried, or juiced, fruits and vegetables are a delicious and nutritious addition to any meal. So, go ahead and eat your five-a-day to stay healthy and feel your best!

Consume whole foods over processed food
Consuming whole foods is generally better than eating processed foods. Whole foods are largely unaltered and appear pretty much as they would in nature. They are rich in nutrients, including vitamins, minerals, fibre, antioxidants, and phytochemicals. In contrast, processed foods are those that have been removed from their natural state through chemical, biological, or mechanical manipulation. This manipulation often diminishes the nutritional value of the food, making it calorie-dense and nutrient-sparse.
Whole foods are nutrient-dense, meaning they contain a variety of nutrients, whereas heavily processed foods contain empty calories and are high in calories, sugar, fat, and sodium while being low in fibre and phytonutrients. The overconsumption of processed foods can lead to weight gain and an increased risk of developing chronic health conditions such as obesity, diabetes, hypertension, hyperlipidemia, and certain types of cancer.
To incorporate more whole foods into your diet, start by adding more fruits and vegetables to your daily intake, aiming for 6-9 servings per day. Include a variety of colours and types of fruits and vegetables to ensure you get a range of nutrients. Additionally, choose whole grains, such as brown rice, whole-grain bread, and oats, over refined grains like white flour, which has been stripped of its fibre and nutrients.
When it comes to protein, opt for lean, sustainably raised meat, poultry, fish, legumes, and soy. These provide essential amino acids and can be good sources of healthy fats. For dairy, choose minimally processed options like plain yogurt, kefir, and cheese, which contain beneficial bacteria and can aid in digestion.
While it's not necessary to completely avoid processed foods, they should be consumed in moderation. Some minimally processed foods, such as fermented milk and cheese, can be part of a healthy diet when consumed in moderation. However, it's important to read ingredient lists and be mindful of the potential presence of harmful added ingredients, high amounts of salt, and artificial ingredients.

Drink water and avoid sugary drinks
Drinking water is essential for maintaining good health. Water is a cheap and healthy way to keep hydrated, and it is sugar-free. Dehydration can cause unclear thinking, mood changes, overheating, constipation, and kidney stones, so it is important to drink enough water to prevent this. The recommended amount is 6 to 8 cups or glasses of fluid per day, and this can include other drinks such as lower-fat milk and sugar-free tea and coffee.
Water is the best way to hydrate, but it is also important to limit or avoid sugary drinks. Sugary drinks are the number one source of added sugars in our diets, and these added sugars can lead to weight gain and damage teeth. Energy drinks, bottled smoothies, and fruit juices can be loaded with added sugars, so it is important to read nutrition labels carefully. One container of these drinks may contain multiple servings' worth of sugar.
Drinking calories may also lead to consuming more calories than needed, as they do not satisfy hunger in the same way as eating food. Therefore, it is recommended to cut back on sweetened drinks and opt for water or less-sweetened versions of these drinks. For example, mixing half sweetened iced tea with half unsweetened iced tea.
Drinking water instead of sugary drinks can help to reduce caloric intake, as water has no calories. This can help with weight loss and maintaining a healthy weight. It is also beneficial to carry a refillable water bottle to make water the go-to choice and add fruit slices for flavor.

Eat reasonable portion sizes
Portion sizes are an important aspect of a healthy diet. Eating reasonable portions can help maintain a healthy weight and prevent overindulging or overeating. Here are some tips to control portion sizes:
Firstly, it's important to understand the difference between a portion and a serving. A portion refers to the amount of food one chooses to eat at a particular time, while a serving or serving size is the amount of food listed on a product's nutrition facts label. Your portion size may be different from the serving size, and it's essential to be mindful of this when consuming packaged foods.
To practice mindful eating, pay attention to your hunger cues and eat until you're about 80% full. Eating slowly and savouring your food allows your brain to register fullness, which can take up to 15 minutes. Using smaller plates, bowls, and glasses can also help reduce the amount of food and drinks consumed.
When dining out, it's common to encounter oversized portions. To manage your intake, consider sharing a meal, ordering a half portion or a children's dish, or opting for a starter and a side instead of a main course. Avoid all-you-can-eat buffets, and choose restaurants that offer controlled portions and healthier options.
At home, use measuring equipment or your plate as a guide to portion control. You can divide your plate into sections for different food groups to ensure a balanced meal. Eating from a plate instead of straight out of the box or bag helps prevent overeating. Freeze leftovers in single or family-sized servings for future meals.
Additionally, planning meals and eating at regular intervals can help prevent overeating. Buying snacks in single-serving packages or dividing larger packages into individual servings can also aid in portion control.

Eat less red and processed meat
While there is some debate about the extent to which red and processed meat should be limited in a healthy diet, most sources agree that reducing intake of these types of meat can have some health benefits. Recommendations from leading health groups, including the American Heart Association and the American Cancer Society, as well as the U.S. Dietary Guidelines, suggest limiting red and processed meats. This is due to evidence that links high consumption of red and processed meat to an increased risk of cancer, heart disease, and other chronic health issues.
However, critics argue that the evidence behind these recommendations is weak and based on low-certainty evidence. They point out that dietary habits are complex and varied, making it challenging to isolate the effects of a single type of food, such as red or processed meat. Nonetheless, while the benefits of reducing red and processed meat intake may be small on an individual level, they can be more noticeable when looking at large populations.
It is worth noting that not all red meat is equal in terms of its health impact. Lean and extra-lean cuts of red meat can provide important nutrients like iron and vitamin B12. In contrast, processed meats and marbled cuts of red meat are less healthy options. As a general guideline, it is recommended to limit red and processed meat consumption to three servings or fewer per week.
Overall, a healthy diet should focus on whole foods over processed ones and include a variety of high-quality fats, carbohydrates, and plant- or animal-based proteins. It is important to remember that individual characteristics, such as age, gender, lifestyle, and physical activity levels, will also influence the specific makeup of a healthy diet for each person.

Frequently asked questions
A healthy diet is generally characterized by an abundance of fresh fruits and vegetables, whole grains, legumes, nuts, seeds, and healthy fats. It is important to limit the consumption of processed foods, baked goods, fried foods, and pre-packaged snacks that are high in sodium and trans fats. The exact composition of a healthy diet may vary depending on individual characteristics such as age, gender, and physical activity level.
Some examples of healthy diets from around the world include the Mediterranean diet, the Nordic diet, the French Paradox, and the West African diet. The Mediterranean diet emphasizes whole grains, legumes, fruits, vegetables, fish, poultry, dairy, and extra virgin olive oil. The Nordic diet is rich in root vegetables, whole-grain bread, and oily fish, while limiting processed dairy. The French Paradox focuses on eating smaller portions of high-quality foods, including bread, cheese, and wine. The West African diet centers on lean meat, vegetables, and cereal staples, with an emphasis on traditional preparations of fruits, vegetables, whole grains, and fish.
A healthy diet provides the body with the nutrients it needs to function correctly and protects against malnutrition and non-communicable diseases such as diabetes, heart disease, stroke, and cancer. It can also help to prevent unhealthy weight gain by balancing energy intake (calories) with energy expenditure.
