What You'll Learn
Include fruits and vegetables
Fruits and vegetables are essential components of a healthy diet and can be incorporated in various ways to make your meals more nutritious and delicious. Here are some tips to include more fruits and vegetables in your diet:
Variety is the Spice of Life
Eating a variety of fruits and vegetables is a great way to ensure you get a range of essential nutrients. Opt for colourful produce, such as dark, leafy greens, vibrant peppers, and citrus fruits, to get a variety of vitamins and minerals. For example, oranges and peppers are rich in vitamin C, while spinach provides iron and kale is a good source of calcium.
Snack Smart
Instead of reaching for processed snacks, opt for fruits and vegetables. Fresh fruits like apples, bananas, and berries are convenient and nutritious. You can also pair them with a healthy dip, such as peanut butter or Greek yoghurt, to make them more filling. For vegetables, try carrot sticks, celery, or sugar snap peas with hummus or tzatziki.
Bulk up Your Meals
Fruits and vegetables are excellent for bulking up your meals and adding extra nutrition. For example, add chopped peppers, onions, and mushrooms to your pasta sauce, or throw in some spinach or broccoli to bulk it up even more. You can also grate or spiralize vegetables like courgettes and carrots to use as a low-carb alternative to pasta. Similarly, cauliflower can be used as a rice substitute or added to rice dishes to increase your vegetable intake.
Smoothies and Soups
Making smoothies with fresh or frozen fruits and vegetables is a great way to get a concentrated dose of nutrients. You can also add extras like oats, chia seeds, or flax seeds to make them more filling. Additionally, vegetable-based soups, such as a hearty minestrone or a blended broccoli soup, are a tasty way to increase your vegetable intake.
Be Mindful of Preparation
The way you prepare your fruits and vegetables can impact their nutritional value. Steaming or stir-frying vegetables can preserve more nutrients than boiling, as some vitamins leach out into the cooking water. Similarly, avoid over-cooking or burning your food, as this can reduce their nutritional value and create harmful compounds.

Choose whole grains
Whole grains are an important source of nutrients, including complex carbohydrates, dietary fibre, several B vitamins, and minerals such as iron, magnesium, and selenium. They have been linked to a reduced risk of heart disease, type 2 diabetes, and cancer. Whole grains have the entire grain kernel, which includes the bran, germ, and endosperm. This is in contrast to refined grains, which have been milled to remove the bran and germ, resulting in the loss of dietary fibre, iron, and B vitamins.
When choosing grains to eat, it is important to limit added sugars, sodium, and saturated fat. Whole-grain bread products are an easy way to add whole grains to your diet. Look for breads with visible grains or seeds, as they tend to be more nutritious. Whole-grain pastas, such as whole-wheat pasta, are also a good option as they have more vitamins, minerals, and fibre than regular pasta. Other examples of whole grains include whole-wheat flour, bulgur (cracked wheat), oatmeal, and brown rice.
Oats are a particularly healthy whole grain that is packed with nutrients. They are a great source of beta-glucans, a type of soluble fibre that has been linked to various health benefits, including lower "bad" LDL cholesterol and total cholesterol levels. Instant oatmeal, however, is more processed and may contain unhealthy added sugar, so it is best to choose whole oats such as steel-cut oats, oat groats, and rolled oats.
Ezekiel bread is another healthy whole-grain bread option. It is made from a variety of whole grains, such as wheat, millet, barley, and spelt, as well as several legumes. The grains and legumes in Ezekiel bread are sprouted, which increases their nutrient content and reduces antinutrients commonly found in whole grains.
In summary, choosing whole grains as part of a healthy diet can provide numerous health benefits, including reduced risk of heart disease and improved digestion and weight management. They are a good source of important nutrients and can be easily incorporated into your diet through whole-grain bread and pasta, oats, and other whole grain foods.

Opt for healthy proteins
When dieting, it is important to eat a wide variety of foods in the right proportions to maintain a healthy body weight. A healthy meal should include healthy proteins, which can be sourced from fish, poultry, beans, and nuts. These foods are versatile and can be mixed into salads or paired with vegetables.
Fish is a good source of protein and contains many vitamins and minerals. It is recommended to eat at least two portions of fish per week, including at least one portion of oily fish. Oily fish are high in omega-3 fats, which may help prevent heart disease. Fish can be canned, frozen, or fresh, but keep in mind that canned and smoked fish can be high in salt.
Poultry is another good source of lean protein. When eating meat, it is important to choose lean cuts and trim any visible fat. It is also important to limit red meat and avoid processed meats such as bacon and sausage, as these can be high in sodium and saturated fat.
Beans are a great plant-based source of protein and are naturally very low in fat and high in fibre, vitamins, and minerals. They can be easily incorporated into meals, such as in a black bean burger or a side of hummus with whole-grain crackers.
Nuts are also a healthy source of protein, but it is important to be mindful of portion sizes and stick to the recommended serving size of 1 ounce. Nuts are high in fibre and healthy fats, but they also contain high levels of fat, so they should be eaten in moderation.

Consume dairy or alternatives
Dairy products, such as milk, cheese, and yoghurt, are excellent sources of protein and calcium. Calcium is essential for healthy teeth and bones, while protein is necessary for the body to grow and repair cells. Dairy products also contain other vital nutrients like iodine, vitamin A, vitamin D, riboflavin, vitamin B12, and zinc.
However, dairy products can be high in saturated fat, which can lead to raised cholesterol levels and an increased risk of heart attack or stroke. Therefore, it is important to opt for lower-fat and lower-sugar dairy options. For example, Greek yoghurt is a tasty, low-sugar, and low-fat option that can be enjoyed on its own or paired with fruit.
Some people may need to avoid dairy products due to lactose intolerance or allergies to cow's milk protein. Lactose intolerance is the inability to digest lactose, the natural sugar found in milk. Those who are vegan may also choose to avoid dairy. Fortunately, there are plenty of dairy alternatives available that can provide similar nutritional benefits. Unsweetened calcium-fortified dairy alternatives, made from plants like soy, coconuts, oats, rice, almonds, hazelnuts, quinoa, and potatoes, can be good substitutes. When choosing non-dairy milk, check that it is fortified with protein and calcium. For example, coconut milk beverage should not be confused with canned coconut milk, and soy, rice, and other cereal drinks should be calcium-fortified.
In cooking and baking, butter can be replaced with dairy-free margarine, cooking oils, fruit purees, or nutritional yeast. For a creamy addition to dishes like curries or pasta, lactose-intolerant individuals can use lactose-free cream, while vegans can opt for coconut cream.

Cook with healthy oils
A dieting meal plan should be well-rounded and balanced, including a variety of food groups in the right proportions. It should include fruits and vegetables, higher-fibre starchy foods, dairy or dairy alternatives, beans, pulses, fish, eggs, meat, and other protein sources.
When it comes to cooking with healthy oils, it's important to choose oils that are stable at high temperatures and that remain healthy after heating. Here are some specific examples of healthy oils to cook with:
Olive Oil
Olive oil is a versatile oil with a subtle peppery or grassy flavour. It can be used for baking, sautéing, or cold dressings. Olive oil is rich in vitamin E, which acts as an antioxidant and has numerous health benefits. It contains oleic acid, a monounsaturated fat that may have anti-cancer and anti-inflammatory properties. It also has heart-healthy compounds and may help prevent conditions like obesity, metabolic syndrome, and type 2 diabetes.
Avocado Oil
Avocado oil has a mild flavour and a high smoke point, making it suitable for various cooking applications. It has a high level of healthy monounsaturated fats and is low in polyunsaturated fats, making it a heart-healthy choice. Avocado oil also contains antioxidants like lutein, which is beneficial for eye health.
Sesame Oil
Sesame oil has been studied for its potential health benefits, and results suggest it has anti-inflammatory properties and may have a positive impact on heart-related factors such as cholesterol levels.
Peanut Oil
Peanut oil is a budget-friendly, high-heat cooking oil with a neutral flavour, making it versatile for many dishes. It is commonly refined, but unrefined or cold-pressed options are also available, with a strong, nutty flavour and aroma.
Chia Seed Oil
Chia seed oil has a high smoke point and a neutral flavour, making it suitable for light sautéing, pasta, and salads. It is rich in omega-3 fatty acids, specifically alpha-linolenic acid, which has heart-healthy benefits and potential neuroprotective effects.
Safflower Oil
Safflower oil is another option that can withstand higher temperatures.
It is also important to note that some oils are not suitable for high-heat cooking and are better suited for cold preparations or as dietary supplements. These include fish oil, flax oil, walnut oil, and palm oil. Additionally, it is recommended to avoid industrially-produced trans-fats found in baked and fried foods, pre-packaged snacks, and cooking oils and spreads.
