What You'll Learn
Eat more fruit and vegetables
Eating a healthy, balanced diet is an important part of maintaining good health and can help you feel your best. Eating more fruit and vegetables is a great way to improve your diet and has many health benefits.
Fruit and vegetables are a good source of vitamins, minerals, and fibre, and should make up just over a third of the food you eat each day. It is recommended that you eat at least five portions of fruit and vegetables every day. They can be fresh, frozen, canned, dried, or juiced. Fruit and vegetables contain vitamins, minerals, and other nutrients that may help prevent heart disease, cancer, and other illnesses. Some of these nutrients include fibre, potassium, folate, and vitamins A and C.
There is evidence that people who eat at least five portions of fruit and vegetables a day have a lower risk of heart disease, stroke, and some cancers. Eating more fruit and vegetables is also a great way to manage your weight. This is because they are low in calories and fat and are filling, helping you to feel fuller for longer.
There are many ways to eat more fruit and vegetables. You can add them to meals, such as tossing a diced zucchini in your spaghetti sauce, or having onions or leafy greens with rice or other grains. You can also add fruit to yoghurt or oatmeal, such as sliced peaches, apples, or pears. Fruit and vegetables also make great snacks, such as a cup of grapes, a banana, or an apple. You can also try having vegetables with a dip, such as hummus with carrots, bell peppers, or cucumbers.
It is important to eat a variety of different fruits and vegetables. The best way to get more nutrients is to eat fruits and vegetables of many different colours. On most days, try to get at least one serving from each of the following categories: dark green leafy vegetables; yellow or orange fruits and vegetables; red fruits and vegetables; legumes (beans) and peas; and citrus fruits.

Choose healthy fats
A healthy, balanced diet is an important part of maintaining good health and can help you feel your best. It is important to remember that not all fats are bad for you. In fact, some fats are essential for your body to function properly.
Good Fats vs Bad Fats
"Good" fats, such as unsaturated fats and omega-3 fatty acids, have been shown to have health benefits, whereas "bad" fats like artificial trans fats and saturated fats are linked to health risks. Monounsaturated and polyunsaturated fats are considered "good" fats because they are good for your heart, your cholesterol, and your overall health. These fats can help to lower the risk of heart disease and stroke, lower bad LDL cholesterol levels, and prevent abnormal heart rhythms.
Sources of Good Fats
- Nuts: In addition to heart-healthy fats, nuts are a good source of protein, dietary fiber, and various vitamins and minerals. Just remember to practice portion control and opt for unsalted nuts.
- Oils: Use oils such as olive, canola, avocado, and other plant-based oils instead of solid fats like butter. These oils are rich in heart-healthy unsaturated fats.
- Avocado: Avocados contain monounsaturated fat and are packed with dietary fiber, potassium, and vitamins.
- Peanut Butter: Peanut butter contains nearly half of monounsaturated fat. Make sure to mix in the heart-healthy oil that separates from natural peanut butter instead of pouring it off.
- Fatty Fish: Include fish high in omega-3 fats at least twice a week. Examples include salmon, mackerel, herring, lake trout, sardines, and albacore tuna.
- Walnuts: Walnuts are a plant-based source of omega-3 fatty acids. Add them to your cereal, salads, or baked goods, or use walnut oil in salad dressings and sauces.
- Flaxseed: Ground flaxseed provides the omega-3-containing oil that your body can access. Add it to breakfast cereal, yogurt, baked goods, or use flaxseed oil for salad dressing.
- Chia Seeds: These small seeds are packed with omega-3s, protein, dietary fiber, vitamins, and minerals. Include them in your cereal, salads, or baked goods.
- Hemp Seeds: Hemp seeds are another great source of omega-3s and protein, and they can be eaten raw, cooked, or toasted.
- Eggs: Some chickens are fed a diet high in omega-3s, resulting in eggs that contain more of this nutrient.
Remember, a nutritious eating plan doesn't mean cutting out all fat but rather focusing on healthier varieties. Aim for 20% to 35% of your total daily calories to come from healthy fats, with less than 10% coming from saturated fats.

Include protein
A beneficial diet is one that comprises a combination of different foods. These include staples like cereals, starchy vegetables, legumes, fruits and vegetables, as well as foods from animal sources such as meat, fish, eggs, and milk.
Protein is an essential macronutrient that plays a key role in the function and structure of your cells, tissues, and organs. Every cell in the human body contains protein, and the body needs a number of amino acids in large enough amounts to maintain good health. The amino acids derived from protein are essential for the body to repair cells and make new ones. This is especially important for children, teens, and pregnant women, who are in key stages of growth and development.
The amount of protein you need in your diet will depend on your overall calorie needs. The daily recommended intake of protein for healthy adults is 10% to 35% of your total calorie needs. One gram of protein supplies 4 calories. For example, a person on a 2000 calorie diet could eat 100 grams of protein, or 400 calories from protein, supplying 20% of their total daily calories.
Protein can be found in both animal and plant sources. Animal sources of protein include meats, milk, fish, and eggs. Plant-based proteins include soy, beans, legumes, nut butters, and some grains such as wheat germ and quinoa.
Protein is important for weight loss and muscle gain. Eating a high-protein diet can help you manage your hunger and cravings, as well as helping your body to heal after injuries. Research also suggests that protein intake combined with resistance training is important as you age, as it could help you maintain bone mass, lowering the risk of osteoporosis and bone fractures.

Limit sugar
A healthy diet is comprised of a variety of different foods, including staples like cereals, starchy vegetables, legumes, fruits and vegetables, and foods from animal sources such as meat, fish, eggs, and milk.
One of the most important things to consider when adopting a healthy diet is limiting your sugar intake. Sugar is one of the main causes of tooth decay, and regularly consuming foods and drinks high in sugar increases your risk of obesity and tooth decay. It can also lead to diabetes, high blood pressure, and liver disease.
The recommended daily limit of free sugars for adults is 9 teaspoons (36 grams or 150 calories) for men and 6 teaspoons (25 grams or 100 calories) for women. However, it is important to note that sugars found naturally in fruits and vegetables are less likely to cause tooth decay as they are contained within the structure. When choosing fruits, opt for tins of fruit in juice rather than syrup, and when drinking fruit juice, limit your intake to 150ml per day.
To reduce your sugar intake, cut down on sweets, cakes, biscuits, and other sugary snacks, and opt for whole foods instead. Read nutrition labels carefully to identify added sugars, which can have more than 50 different names, and be aware that sugar is in about three-quarters of all prepackaged foods. Choose unsweetened wholegrain breakfast cereals and add fruit for sweetness, and opt for water, lower-fat milk, or sugar-free drinks instead of sugary fizzy drinks.
