Artificial dyes are made from chemicals derived from petroleum… the same stuff used to make gasoline, diesel fuel, asphalt, and tar.

Artificial dyes have been linked to:
brain cancer

nerve-cell deterioration
hyperactivity in children

Despite the bad history, it seems the government is okay with using us as the subjects for their science experiments. As of 2007 the following seven artificial colorings are permitted in food (the most common in bold) in the United States:

Blue No. 1
Blue No. 2
Green No. 3
Red No. 40
Red No. 3
Yellow No. 5
Yellow No. 6
Check your labels. If your food has to be colored for you to eat, you don't want it, or need it.

Same with household cleaners, laundry detergents, scented products. They now make scented magic markers and crayons for kids. What do people do when the smell something they find pleasant? They take in a deep breath. I have always been super-sensitive to scented products and am guessing it is the petroleum in it, I hold my breath when walking down the candle, laundry and cleaning aisles of the stores or have a headache within a few minutes. Normal selfcare products like shampoos and conditioners, I order them online, just the basics with no scents or all the other junk put into it... before that I found myself in the shower with 4 different brands of shampoo and almost crying trying to figure out which would cause the least amount of damage. My eyes would puff shut and I'd break out all over my body from them.... I had to search for something my body could handle. But most people aren't even aware of the vast amounts of toxins in the products they use daily. Add chemicals in foods.
