Do you know what the nutritional difference is between a carrot from 1970 and the one we eat today? It may sound exaggerated to you, but it is a reality, the foods grown today decades ago were much richer in vitamins and minerals. If we talked about this it is obvious when it comes to industrialized products, but the problem is much deeper: Is it possible to obtain nutrients from modern foods?
Food is essential for our survival, a fundamental requirement for life and provider of strength, vitality and energy.
Foods are substances of a complex nature that contain Changsha Mobile Number List the elements necessary for the maintenance of vital functions.
The least nutritious foods come from eroded, low organic matter and contaminated soils . The relationship between #humanhealth and the good condition of
However, the relationship we have with them has changed in the last 50 years. Even a simple potato has 100% less vitamin A, 57% less vitamin C, and 28% less calcium than it did in 1950. Yes, potatoes used to be super nutritious. Nowadays, they are basically tasteless vessels for fat.
A 2004 American study found that important nutrients in some garden crops are up to 38% lower than in the mid-20th century .
The study also detailed that on average, of 43 vegetables analyzed, the calcium content decreased by 16%, iron by 15% and phosphorus by 9%. The vitamins riboflavin and ascorbic acid were significantly reduced, while there was a slight decrease in protein levels. As if that were not enough, nutritional decreases have also been observed in wheat

Today's foods are less nutritious
What is happening? According to an investigation by the BBC news portal , after World War II, motivated by food shortages, scientists worked on the development of new variants of crops and high-performance breeds of livestock; They promoted the use of pesticides and herbicides for food production. Crops increased dramatically.
The average global cereal yield increased by 175% between 1961 and 2014 , with wheat, for example, going from an average yield of 1.1 tonnes per hectare to 3.4 tonnes per hectare in around the same time period.
Although food needs were met, nutrient levels in some crops decreased. Could it be, as some have claimed , the result of the increased use of artificial pesticides, fertilizers and other products that have altered the balance of soil life, the health of crop plants and therefore the quality of the food?
The BioNutrient Food Association's Real Food Campaign found massive variations in the amount of minerals in 200 different samples of carrots. An analysis by the Kushi Institute used nutrient data from 1975 to 1997 and found that average calcium levels in 12 fresh vegetables fell 27% overall.
Where are the nutrients?
Ironically, the conclusion many researchers have come to: growing plants for higher yields (rather than nutrients) is to blame. While this is certainly one piece of the puzzle, breeding seeds for traits like higher yields or better pest resistance does not necessarily decrease nutrient density on its own.
Traditional plant breeding is simply crossing the most desirable plants and selecting the best offspring to continue saving seeds.
The above reveals that the food revolution helped fight world hunger, today we find a global food system that, in some cases, has provided calories and cosmetic perfection... but not necessarily nutrition.
