Our diet plays a crucial role in our overall health, influencing everything from energy levels to disease prevention. While we may have more access to food than ever before, the nutritional value of modern food has declined. Understanding how your diet affects your health can help you make informed choices that support your well-being.
The Declining Nutritional Value of Food
Over the past several decades, the nutrient content of many common foods has quietly declined. As farming practices and food production methods have changed, so too has the quality of the food on our plates.
A 2004 study found that important nutrients in some vegetables have declined by nearly 38% since 1950. Another study discovered that high-yield fruits and vegetables have lost between 25-50% of their original nutritional density due to environmental, genetic, and soil depletion factors.

What Can Cause this Decline?
Advances in agriculture have increased crop yields but often at the expense of nutrient content. Modern farming techniques prioritize quantity over quality, so while today’s produce may look bigger and more appealing, it often contains fewer vitamins and minerals than food grown decades ago. The rise in hidden hunger, a term used to describe when people consume enough calories but are not receiving essential nutrients, illustrates a growing concern.

The Hidden Hunger Problem
Despite living in an era of ‘food’ abundance, many people suffer from hidden hunger. Ultra-processed foods are a major contributor to this issue because they are typically high in calories, sugar, and unhealthy fats but low in essential nutrients.
Research links ultra-processed food consumption to obesity, diabetes, heart disease, and even mental health disorders. For a closer look at the global health risks of ultra-processed foods, check out Time for a Noodle Tax? The Impact of Ultra-Processed Foods on Health.
Making Smart Dietary Choices
Understanding how diet affects health means taking a proactive approach to nutrition. While food quality may be on the decline, there are still ways to ensure we are eating nutrient-dense meals.
1. Prioritize Whole Foods
Fresh fruits, vegetables, whole grains, and lean proteins should be the foundation of your diet. These foods provide essential vitamins and minerals that support everything from brain function to heart health. Canada’s Food Guide recommends an emphasis on plant-based proteins and whole foods for better overall health.

2. Read Food Labels Carefully
Not all food is created equal. Learning how to read nutrition labels can help you make better food choices. Look for those with minimal added sugars that contain healthy fats and whole-food ingredients.
A helpful resource for decoding food packaging is How to Read a Food Label.
3. Limit Ultra-Processed Foods
Cutting back on ultra-processed foods (UPF) is one of the best ways to improve your diet. While UPFs may be convenient, their long-term impact on health should concern consumers. Replacing ultra-processed foods with fresh, minimally processed options can help prevent nutrient deficiencies and chronic disease.

4. Consider Soil Health and Farming Practices
Nutrient-rich food starts with healthy soil. Choosing organic or locally grown produce can help ensure higher-quality food selections. Farming techniques such as regenerative agriculture aim to restore soil health and improve the nutritional density of crops.

Conclusion: The Power of a Healthy Diet
What we eat has a direct impact on our health. While modern production has enabled easier access to food, these practises have also resulted in lower nutritional quality. Understanding how diet affects our health can help us make better food choices such as prioritizing whole, nutrient-dense foods and avoiding ultra-processed products.
