It's something many people struggle with everyday, making healthy food choices.
Now some folks are looking to the past to find the answers.
You may have heard it called the "caveman diet" or the Paleo diet and it's gaining popularity.
The premise harkens back to what our ancestors used to eat; meat, vegetables, seeds, nuts and some fruit.
Dairy and grains are out.
Many who follow the guidelines say it's really a lifestyle choice, not a "diet."
The Paleo diet is also gluten free so it works for those with chronic health issues like Celiac's diesase.
