The secret connection between soil quality and nutrient density: what is the impact?
The concept of nutritional density gradually emerges when discussing healthy diets, an indicator that reveals the proportion of health-benefit nutrients in a particular food relative to their energy content.However, this indicator is closely related not only to the food itself, but also closely linked to the quality of the soil and its mineralization level.This means that the nutritional value of the food we consume depends to some extent on the environmental quality of the plant's growth.
According to the World Health Organization's definition, nutritional analysis is the classification and ranking of foods through the nutritional content of food to promote health in humans and animals and prevent disease.Therefore, grading the nutritional density of food has become a common nutritional analysis strategy.
When measuring the nutritional density of foods, experts usually compare it with energy content, which allows foods rich in trace elements such as meat, fruits and vegetables to be high-energy foods such as alcohol In sharp contrast with high-sugar processed foods.
The study points out that there is a complex relationship between nutrient density and soil quality and mineralization level.The minerals and trace elements contained in the soil will directly affect the growth of plants and will also determine the nutritional composition of the food we finally see on the plate.Therefore, attaching importance to soil health is undoubtedly one of the important factors that promote the effective increase in food nutrition density.
Establishment of international standards
Internationally, multiple standards have been established to evaluate the nutritional properties of foods.For example, nutritional analytics calculators in Australia and New Zealand provide a reference standard for food claims designed to promote healthier dietary options.In addition, the UK's Ofcom nutrition analysis model provides a single score for food products based on a negative and positive nutritional component scoring system, which has a certain degree of comparison.
Although a variety of different standards have been introduced, no international consensus has been reached, reflecting the diversity of measures and indicators for nutrient density.How to establish an effective set of standards remains an ongoing challenge in the scientific community.
Criticism of nutrition density measurement
However, the measurement of nutrient density has also been criticized.First, comparing the ratio of food to its energy content is simple enough, but it prioritizes trace elements over bulk nutrients, which may lead to some foods with excellent micronutrients with low scores due to their high energy content.
Furthermore, the measurement of nutrient density does not show what necessary nutrients a certain food lacks.Even a food-scoring full score may not actually provide the complete nutrition people need.In addition, whether the nutrients selected for evaluation are close to people's actual needs is another urgent issue to be solved.
The necessity of attaching importance to soil quality
With the advancement of agricultural science and technology, the attention to soil and its health status has gradually increased.Healthy soil provides the essential elements needed by plants, which not only affects the taste and quality of food, but also concerns our health.Therefore, the concept of nutrient density should not be limited to the food itself, but should also be extended to the natural resources that produce these foods.
Many experts point out that if we want to improve the overall health of our people, we should focus not only on improving dietary intake, but also on soil health to achieve a more comprehensive solution.
With a deep understanding of the link between nutrient density and soil quality, can we rethink the impact of modern agricultural methods and dietary choices?
