A major factor influencing the properties of agricultural crops and their products, experts have called global warming on Earth. The air temperature increase, in their view, gives rise to adverse processes in the cereal plants - for example, in wheat and maize. In them, the studies show that there may be toxic compounds.
 
"The concentration of these toxins are not so high as to cause any immediate effects, but in the case of prolonged use of poisonous herbs, can lead to serious health problems," - commented on the experts.
 
Similar toxins under the influence of solar activity also grew up in the form of grains such as barley, millet, soybeans and sorghum. UN experts noted that under normal temperature conditions, plants absorb from the soil components, which are then converted to amino acids and proteins, making them useful for human health. However, due to the fact that the climate is becoming hotter malfunction occurs in conventional biological processes and plants begin to abnormally accumulate a concentrated toxic substances.
 
Note that earlier, some scholars have also expressed that the modern herbal products significantly poorer on the vitamins and other nutrients.
