In today’s world, where information about nutrition is abundant, it can be overwhelming to determine the best dietary practices. However, renowned scientific bodies and health organizations across the globe have provided valuable insights into formulating universal principles of a healthy diet. Let’s delve into the recommendations from scientists in Canada, Great Britain, and international bodies to understand the key guidelines for cooking, grocery shopping, and dining out.
World Health Organization (WHO) Recommendations: Emphasizing Diversity

- 3 Canadian Recommendations: Emphasizing Fruits, Vegetables, and Unsaturated Fats
- 4 Great Britain Recommendations: The Balanced Plate Approach

The WHO recommendations prioritize diversity in food choices rather than specific products. While avocados, fish, and nuts are mentioned as examples of recommended fats, the focus remains on a varied diet. Regarding salt intake, consumption levels differ significantly between countries, ranging from 0.5 grams to 25 grams per day in Japan.
- Consume at least 400 grams of different vegetables and fruits daily.
- Limit daily salt intake to less than 5 grams.
- Restrict added sugar intake to less than 10% of energy intake.
- Replace saturated fats and trans fats with unsaturated fats found in fish, avocados, nuts, and oils like sunflower, soy, canola, and olive oils.
- Minimize saturated fat intake to less than 1% of calorie intake.
United States Recommendations: Prioritizing Variety and Limiting Saturated Fat
Although the United States might not be the standard for life expectancy and excess weight, its scientific approach to nutrition is commendable. The recommendations emphasize diversity, inclusion of various food groups, and moderation of added sugar and salt.
- Focus on variety, nutrition, and quantity by incorporating a wide range of food groups.
- Restrict calories from free sugar and saturated fat.
- Limit daily salt intake to less than 2.3 grams.
- Customize a healthy and varied diet based on cultural preferences and personal choices.
- Include a variety of vegetables, whole fruits, and grains, with at least half of the grains being whole.
- Consume low-fat dairy products, seafood, lean meats, poultry, eggs, legumes, nuts, seeds, and soy.
Canadian Recommendations: Emphasizing Fruits, Vegetables, and Unsaturated Fats
Canadian dietary guidelines align closely with those of other countries. They highlight the importance of fruits, vegetables, and unsaturated fats. Notably, water is the recommended beverage of choice, promoting a shift away from sugary sodas and juices. Additionally, the guidelines acknowledge the significance of cultural preferences and traditions, encouraging individuals to embrace local produce and customs.
- Include fruits, vegetables, whole grains, and various protein sources, including plant-based options.
- Protein sources: legumes, nuts, seeds, tofu, soy milk, fish, seafood, eggs, poultry, lean red meat, skim milk, yogurt, cheeses, and kefir.
- Replace foods high in saturated fats with those high in unsaturated fats.
- Prioritize water as the preferred drink.
- Nutritious foods can be frozen, chilled, canned, or dried.
- Consider cultural preferences and traditions when making dietary choices.
- Eating with others fosters joy and strengthens intergenerational and intercultural bonds.
Great Britain Recommendations: The Balanced Plate Approach
In line with several other nations, the UK presents its dietary recommendations using a plate model. The guidelines promote the consumption of clean water, ample fruits, and vegetables. The plate also includes fish, poultry, eggs, legumes, and dairy products, with cheese in moderation. Whole grains, such as whole grain pasta, are recommended, while foods high in salt, sugar, and unhealthy fats should be limited.
- Maintain a balanced plate with an emphasis on water, fruits, and vegetables.
- Include fish, poultry, eggs, legumes, and limited amounts of dairy products and cheese.
- Consume whole grains, such as whole grain pasta, for a healthier diet.
- Minimize consumption of foods high in salt, sugar, and unhealthy fats.
Common Ground: Variety and Plant-Based Foods
The key to a healthy diet lies in embracing variety and favoring plant-based foods. Renowned experts, including Tim Spector, author of “Diet Myths,” and nutritionist Marion Nestle, emphasize these principles. Our ancestors, around 15,000 years ago, consumed approximately 150 different ingredients every week. In contrast, most people today consume fewer than 20 individual foods. Thus, incorporating new foods and rotating dietary choices is vital. Consider consciously adding a new ingredient to your menu each week or every two weeks.
Additionally, almost all healthy diets revolve around moderation and a plant-based focus. Nutrition experts like Michael Pollan and Marion Nestle advocate for consuming less processed food, increasing fruit and vegetable intake, and minimizing fast food consumption. Physical activity is equally important, as centenarians exemplify. They engage in regular walking, swimming, and other forms of physical movement, rather than extreme workouts.
Practical Implementation: Simplicity as the Key
The complexity of dietary recommendations often overwhelms individuals, making adherence challenging. Studies suggest that the simplicity of instructions positively influences compliance. Therefore, the aforementioned recommendations excel in their simplicity and practicality.
Additional Simple Nutritional Rules:
- Prioritize single-ingredient foods over heavily processed ones, following the Chinese wisdom of “one leg” over “two or four legs.”
- Consider meat, if consumed, as a flavorful addition rather than the main course.
- Opt for colorful vegetables and fruits to enhance nutrient variety.
- Satisfy your sweet tooth with natural options like fruits and berries.
- Assess your hunger level and avoid overeating by asking, “Have I satisfied my hunger?”
- Be cautious of lengthy ingredient labels, as shorter ones often indicate healthier choices.
- Steer clear of foods claiming to be healthy, as they may not align with nutritional goals.
- Select products with fewer than five ingredients whenever possible.
- Choose perishable foods, as they are generally healthier than highly processed alternatives (exceptions apply, such as honey, which has a long shelf life).
- Minimize reliance on supermarket purchases and opt for homemade meals.
- Support local food producers instead of relying on corporate products.
- Refrain from purchasing products advertised to children using cartoon characters, as advised by Marion Nestle.
- Cultivate the habit of reading labels and choose foods that your great-grandmother would recognize as food. Most supermarket products would likely confuse our ancestors due to their unfamiliar composition.
By incorporating these straightforward guidelines into your daily life, you can establish a nourishing and sustainable approach to nutrition. Remember, a healthy diet should be a source of joy, connecting you with the rich tapestry of culinary possibilities while promoting overall well-being.
