There are farmer's markets everywhere. Buy local and buy fresh helps you and local businesses. Eating more veggies is a good start. Now let's start to focus on organic without pesticides and harmful sprays.
We all want to eat what is good for us. Eating foods that have been sprayed with harmful toxins become a part of what is in you. That old saying "You are what you eat" really applies with every bite and every sip you take.
Look at your labels. If you can't say it, read it or see things you don't recognize put it back. Look for better options. If you are new to this ask a clerk for some help with your selections. They are their to help you and guide you.
Remember taking care of yourself means eating better.
