Do we need supplements?

We are not eating the same foods our great-parents ate, nor are we living the same lifestyles. Our earth's environment is different as is our work environment. Foods are often picked before becoming ripe. When we eat food picked before it is ripe, it decreases the nutrient content of that food. Many of today's food are processed with extra ingredients such as fillers and preservatives. Today, a modern loaf of bread contains over 100 ingredients including preservatives, coloring agents, insecticides, herbicides, fungicides and chemical residues from various packaging and cleaning procedures.
