Why our diet is not enough

Why Our Diet Isn't Always Enough: Nutrient Deficiencies Explained

In a world where we have access to a wide variety of foods, you might think that a balanced diet is enough to meet all of our essential nutrient needs. However, the reality is more complex. Even the best-planned diets can sometimes leave gaps in vitamin and mineral intake. Here’s why, with a scientific look at the challenges of our daily nutrition.

1. The nutritional quality of food is declining

Over the years, the nutritional quality of food has declined significantly. A study from the University of Texas at Austin found that when comparing today's vegetables and fruits to those from the 1950s, their content of calcium, iron, vitamin C and other essential nutrients has dropped drastically. Why?

• Soil depletion : Modern agricultural practices, such as monoculture and intensive use of chemical fertilizers, reduce the richness of soils in essential micronutrients.
• Early harvest : Fruits and vegetables are often harvested before maturity to facilitate transport, which limits their natural nutrient accumulation.

2. Preparation and cooking methods play a role

Did you know that the way you prepare your food can have a significant impact on its nutritional value?

• Loss of water-soluble nutrients : Cooking in water, such as boiling, results in the loss of water-soluble vitamins, including vitamins B and C.
• Oxidation : Prolonged exposure of foods to air can cause some antioxidants to break down.

To minimize these losses, favor methods such as steaming or eating raw vegetables when possible.

3. Variable and specific nutritional needs

Each individual has specific needs depending on their age, gender, level of physical activity and health conditions.

• Stress and physical activity : Both of these factors increase the need for certain nutrients, including B vitamins and magnesium.
• Life stages : For example, pregnant women have increased needs for iron and folic acid, while older adults may have difficulty absorbing vitamin B12.

4. “Hidden” nutrients in processed foods

Processed foods, often high in calories, are seriously lacking in essential nutrients. These ultra-processed foods, while they may seem convenient, sometimes replace whole, nutritious foods on our plates.

• Excess sodium and sugars : They disrupt electrolyte balance and increase micronutrient requirements.
• Lack of fiber : This affects intestinal health, limiting the effective absorption of vitamins and minerals.

5. Absorption sometimes compromised

Even if you eat foods that are rich in nutrients, your body still needs to be able to absorb them properly.

• Nutrient interference : Some nutrients, such as calcium and iron, may compete for absorption in the intestine.
• Digestive disorders : Conditions such as irritable bowel syndrome or celiac disease can affect the assimilation of nutrients.

6. Why additional support can be useful

While the goal remains to eat a balanced and varied diet, these challenges show that this is not always enough to meet all our needs. Complementary solutions, such as a well-balanced vitamin and mineral supplement, can then play a key role in supporting our overall health.
