The Nourishment Table for Science-Based Nutrition

In an era marked by conflicting dietary advice and escalating health concerns, a group of leading researchers, headed by Professor Frederic Leroy of Vrije Universiteit Brussels, has developed the Nourishment Table. This pioneering model proposes a move away from the conventional “Healthy Diet” narrative towards a more nuanced concept of “Adequate Nourishment”.

This shift emphasises the importance of nutrient quality rather than adhering to overly simplistic dietary labels, accommodating diverse cultural and economic backgrounds with a foundation in robust scientific research. The Nourishment Table is designed to empower individuals with the knowledge needed to make personalised food choices and influence future dietary policies.

A Tailored Nutritional Strategy

The Nourishment Table stands apart from one-size-fits-all dietary guidelines by offering a customisable, evidence-based approach. It focuses on two main aspects: the nutrient density of foods, which looks at the balance of vital nutrients like proteins and micronutrients against caloric content, and the extent of food processing.

Studies indicate that diets incorporating 25-30% of calories from animal products—such as meat, dairy, fish, and eggs—can lead to better health outcomes. These foods are rich sources of high-quality protein, essential fatty acids (like DHA and EPA), various micronutrients (including haem iron, zinc, calcium, iodine, retinol, vitamins D3 and B12), and unique bioactive compounds (such as choline, taurine, creatine, carnitine, carnosine) that are either scarce or absent in plant-based diets.

The Issue with Ultra-Processed Foods (UPFs)

The conventional advice on healthy eating has not successfully guided populations towards better dietary habits. Despite an abundance of food options in affluent societies, there’s a growing reliance on ultra-processed foods (UPFs). These foods, often misleadingly marketed as healthy, are predominantly manufactured by large corporations to maximise profit, substituting for more nutrient-dense animal products.

UPFs typically involve disrupted food matrices made from inexpensive, processed ingredients like sugars, starches, seed oils, and protein isolates, combined with numerous additives such as colours, flavours, sweeteners, and emulsifiers. Their hyper-palatability encourages overconsumption, contributing to obesity and metabolic issues, while their promotion under misleading sustainability or health labels further confuses consumers.

Promoting Balance with the Nourishment Table

In nations like Pakistan, Egypt, and Mexico, diets low in animal-sourced foods correlate with significant nutrient deficiencies and increased incidences of diseases like Type 2 diabetes. This underscores the need for dietary advice prioritising nutrient density over simplistic dietary shifts. The Nourishment Table advocates for a balanced diet that respects personal preferences, cultural heritage, and economic constraints. It promotes a core diet filled with medium to high nutrient-density and minimal to moderate processed foods. This approach is adaptable, catering to various dietary needs across different demographics.

The two Versions of the Nourishment Table

The Nourishment Table comes in two forms:

Principle-Based Version: This provides a foundational framework outlining the core principles of nourishment, focusing on the interplay between nutrient density and food processing without prescribing specific diets.

Illustrative Version: This extends the principles by offering concrete examples from both historical and contemporary diets, illustrating how they fit into the Nourishment Table based on nutrient content and processing levels. This version aids in understanding how food choices affect nourishment in practical terms.

This dual framework not only aids individuals in making informed dietary choices but also can help shape policy by providing a clearer picture of nutritional needs across various populations.

The Nourishment Table is more than just a dietary guideline; it’s a call for policymakers to embrace food policies grounded in science that balance nutritional quality with sustainability. As Frederic Leroy states, “Adequate nourishment transcends the concept of a ‘healthy diet’. It’s about a practical, scientifically-supported approach to meeting our nutritional needs, respecting individual choices, and aiding consumers in selecting nourishing foods daily”.
