What are the 8 Dietary Guidelines for a Healthy Nutrition Diet?

According to the World Health Organization (WHO), an unhealthy diet is a leading global risk to health. To combat this, many public health bodies, such as the UK's National Health Service, provide clear, actionable advice based on scientific evidence. Here is a breakdown of what are the 8 dietary guidelines and how to apply them for a balanced nutrition diet.

Quick Summary

Practical tips for a balanced diet include basing meals on fiber-rich carbs, eating plenty of fruits and vegetables, choosing lean protein sources, limiting saturated fat, sugar, and salt, and ensuring proper hydration.

Key Points

• Embrace Wholegrains: Base your meals on high-fibre starchy carbohydrates, such as wholewheat bread, pasta, and brown rice, for sustained energy and good digestion.

• Pile on Produce: Aim for at least five portions of varied fruits and vegetables daily to load up on essential vitamins, minerals, and fibre.

• Choose Lean Protein and Fish: Include beans, pulses, eggs, lean meat, and at least two portions of fish per week (one oily) for protein and omega-3s.

• Limit Bad Fats, Sugar, and Salt: Reduce intake of saturated fats, added sugars, and salt to decrease your risk of heart disease and weight gain.

• Stay Hydrated: Drink 6-8 glasses of fluid, preferably water, daily to support proper bodily functions and help control appetite.

• Don't Skip Breakfast: A healthy breakfast helps manage appetite throughout the day and fuels you for the morning.

• Cook at Home: Take control of your ingredients by cooking more meals yourself, which reduces hidden additives like salt and sugar.

• Balance Your Energy: Pair a balanced diet with regular physical activity to manage your weight and feel your best.

A healthy diet is essential for supporting overall well-being, from maintaining a healthy weight to reducing the risk of chronic diseases like heart disease, stroke, and type 2 diabetes. Rather than adhering to restrictive fads, focusing on fundamental dietary principles is far more sustainable and beneficial. The following eight guidelines, based on widely accepted public health advice, provide a clear roadmap for improving your eating habits.

The 8 Key Dietary Guidelines

1. Base your meals on higher fibre starchy carbohydrates

Starchy carbohydrates, like potatoes, bread, rice, and pasta, should make up about one-third of your diet. They are an important source of energy, and choosing higher-fibre, wholegrain varieties—such as wholewheat pasta, brown rice, and wholemeal bread—can provide more fiber, vitamins, and minerals. Fibre aids digestion, helps you feel full for longer, and can help control blood sugar levels. For example, when eating potatoes, try keeping the skin on for an extra fibre boost.

2. Eat lots of fruit and vegetables

It is recommended to eat at least five portions of a variety of fruit and vegetables every day. These are vital sources of vitamins, minerals, and antioxidants that protect against noncommunicable diseases and aid overall health. A portion can be fresh, frozen, canned, or dried. Ideas include adding a banana to your morning cereal, swapping a snack for an apple, or adding a side salad to your lunch.

3. Eat more fish, including a portion of oily fish

Fish is a good source of protein, vitamins, and minerals. Aim for at least two portions of fish per week, with one portion being an oily fish. Oily fish, such as salmon, mackerel, and sardines, are rich in omega-3 fatty acids, which can help prevent heart disease. Fresh, frozen, or canned fish can be used, but be mindful that canned and smoked fish may contain more salt.

4. Cut down on saturated fat and sugar

Excessive intake of saturated fats and sugar contributes to obesity, heart disease, and tooth decay. It's important to choose unsaturated fats (e.g., vegetable oils, oily fish, avocados, nuts) over saturated fats (e.g., fatty meat, butter, hard cheese). Similarly, reduce your intake of added sugars found in fizzy drinks, cakes, and sweets. Your taste buds will adjust over time, and you'll find less sugary foods more satisfying.

5. Eat less salt

High salt intake is a major contributor to high blood pressure, increasing the risk of heart disease and stroke. Adults should consume no more than 6g of salt per day (about a teaspoon). Most of the salt we eat comes from processed and packaged foods, so checking food labels is crucial. To add flavor to home-cooked meals, use herbs, spices, and lemon juice instead of salt.

6. Get active and maintain a healthy weight

Balancing the energy you consume with the energy you use is critical for maintaining a healthy weight. Regular physical activity, such as 150 minutes of moderate exercise per week, is as important as a balanced diet. If you need to lose weight, focus on eating fewer calories and being more active.

7. Don't get thirsty

Adequate hydration is essential for numerous bodily functions, including regulating temperature, protecting organs, and delivering nutrients to cells. Aim for 6 to 8 glasses of fluid daily. Water is the best choice, but lower-fat milk, tea, and coffee also count. Limit sugary drinks like soda and fruit juice, which are high in calories and sugar.

8. Don't skip breakfast

Eating a healthy breakfast can help prevent overeating later in the day by providing a steady source of energy. A fibre-rich, low-sugar breakfast, like wholegrain cereal with fruit and low-fat milk, is an excellent choice. Skipping this meal can lead to energy crashes and stronger cravings for less healthy foods.

Practical Tips for Adhering to the Guidelines

Incorporating these guidelines into your daily life can be straightforward. Here are some actionable steps:

• Read Food Labels: The Nutrition Facts panel on packaged foods shows the amount of added sugars, saturated fats, and sodium. Compare brands and choose those with lower quantities.
• Cook at Home More Often: Preparing meals at home allows you to control the ingredients, reducing hidden salt, sugar, and fat found in many ready-meals and takeaways.
• Use Herbs and Spices: Flavor your food with natural alternatives like garlic, ginger, paprika, and oregano instead of relying on salt.
• Focus on Whole Foods: Prioritize fresh fruits, vegetables, legumes, and whole grains over highly processed, packaged options.
• Plan Your Meals: Creating a weekly meal plan and shopping list can prevent impulse purchases of less healthy foods.
• Hydrate Throughout the Day: Keep a reusable water bottle with you and opt for water instead of sugary beverages to stay hydrated.

Frequently Asked Questions

How can I reduce my intake of saturated fat?

To reduce saturated fat, opt for lean cuts of meat, remove skin from poultry, and replace butter and lard with unsaturated oils like olive or sunflower oil. Choosing lower-fat dairy products can also make a significant difference.

What counts as one portion of fruit or vegetables?

A single portion can be an apple, banana, or other similar-sized fruit; 3 heaped tablespoons of vegetables; or a small glass (150ml) of fruit juice, which counts as a maximum of one portion per day.

Is it possible to 'retrain' my taste buds to prefer less salt?

Yes, you can gradually reduce your salt intake, and over time, your taste buds will adapt. Use herbs, spices, lemon juice, or vinegar for flavor instead of relying on salt.

Are wholegrains always a healthier choice than refined grains?

Yes, wholegrains are generally a healthier choice because they contain the entire grain kernel, including the fibre-rich bran and nutrient-packed germ, which are removed during the refining process. This makes them more nutritious and helps regulate blood sugar levels.

What are some sneaky sources of added sugar I should watch out for?

Added sugars can be hidden in many processed foods, including cereals, packaged snack bars, and 'diet' foods where fat has been removed and sugar added to compensate for flavor. Always check the nutrition label for added sugar content.

How do I choose healthier protein sources?

For healthier protein, choose lean meats, fish, eggs, and plant-based proteins like beans, lentils, nuts, seeds, and tofu. Limit red and processed meats such as bacon and sausages.

Can I get enough hydration from other drinks besides water?

While water is the best option, other fluids like low-fat milk, tea, and coffee contribute to your daily fluid intake. However, avoid relying on sugary drinks and be mindful of the caffeine content in tea and coffee, as it can have a diuretic effect.
