But solutions are not at all simple particularly in terms of from agricultural and consumer practices.

Is our food becoming less nutritious? If we use the most useful definition of “nutritious” —“having a macronutrient profile that is conducive to health, and a high ratio of micronutrients to calories” — the short answer is yes, and quite severely. Macronutrients include carbohydrates, protein, fat and fibre, and the distribution of these nutrients, and quality of each, strongly influences overall metabolic health. Micronutrients primarily include vitamins, which are organic molecules produced by living organisms, and minerals, which are chemical elements or molecules of those elements that are necessary for biological function. This is an important distinction, because a plant can generally produce vitamins from the same basic building blocks it uses for growth, but if a particular element is not present in soil then it simply can’t end up in a plant grown in that soil.
