Yes, but at first it’s not obvious. Accumulating toxins from pesticides and herbicides has a big impact on your digestion and the rest of your body over time. The liver continually detoxes chemicals from food and the environment on a day to day basis however, there is only so much it can take.
There are many studies that show large amounts of pesticides in the umbilical cords of newborn babies and in the fat cells of adults. Another reason to buy organic is that a lot of foods are irradiated and people think it’s better than pesticide use but irradiation has its own health problems.
Organic food could extend your life and research has shown this to be true in animals.
