Food allergies and intolerances are continually increasing among humans, dogs, and cats. While there is no clear scientific evidence, the cause seems to be strictly connected to the enormous increase of polluted substances (xenobiotics) present in the environment and food chain. If we look to the polar bear as an example, we find an animal that lives in an environment far from immediate pollution, yet still has been contaminated and has suffered especially in their fertility. This degree of contamination has been carried throughout the food chain: the bear eats fish and seals, which in turn feeds upon fish of a smaller size, which feed on algae or plankton. Because the chemical substances that we pour into the rivers and seas don’t break down, we are assisting this phenomenon of progressive accumulation (bio accumulation) in the different species that live in the sea. The reproductive difficulties of an animal that lives far from any negative stimulus should give pause. As a veterinarian of cats and dogs, I can say with certainty that the fertility in dogs has dramatically decreased in the last 30 years. Even more impressive is the decrease in number of puppies in a litter, often reduced to half of the physiological number. As for sperm analysis, too many males are affected by reduction in quantity and vitality.
The introduction of the polluted substances (antibiotics, hormones, phyto-pharmacy, pesticides, fungicides, melamine, dioxin, polychlorinated biphenyls, nitrites, nitrates, etc.) happens also through the air and water, but the basic carrier is food.
Through the food chain they reach the residues in 200 million tons of synthetic chemical products, used specially in agriculture and in the intensive farming. If we consider that before the second world war, the world production of chemical products was around one million tons, we can have a clear explanation of the explosion of intolerance and allergies.
Those who lived their childhood after the war can confirm that in that period, food intolerances did not exist and allergies were enormously infrequent. Furthermore, the appearance of allergies happened exclusively in early childhood or adolescence. Now, both intolerances and allergies appear for all ages, and it’s not uncommon to see a sudden appearance of such phenomenon in people of 70 or 80 years old and in dogs or cats of 10, 12, or more years old.
Every individual has a specific capacity for “absorbing” such poisons. Beyond this capacity appears allergies and intolerances.
There is a way to eliminate or at least limit these relentless problems; Introduce the foods that prove to have a lower negative impact (fish, fish oil, extra virgin olive oil, linen oil, rice, and vegetables) and those with an antioxidant function (curry or agave syrup) that counteract the negative effect of pollutants.
