It's tough to eat healthy, and even tougher to find healthy foods on a budget. Even though eating well is an investment in your long-term health, it can be hard to find nutrient-dense, environmentally friendly foods that don't hit your wallet.
Environmental Working Group, a non-profit research organization, has examined over 1,000 foods to determine the ones that have the fewest pesticides, contaminants and artificial ingredients... and are reasonably priced. Their printable booklet "Good Food on a Tight Budget" offers tips for healthy, inexpensive foods.
