The 4Leaf Survey keeps getting better.

Leveraging the simple concept of maximizing our percent of daily calories from whole, plant-based foods.

And it may very well be the world’s first survey of its kind.

Twelve questions—2 or 3 minutes. A quick and easy way to estimate how healthy you are eating…without counting calories or computing percentages. (latest revision 3-26-12)

What are we measuring? The 4Leaf Program is based on the simple premise put forth by Dr. T. Colin Campbell, “The closer we get to eating a whole foods, plant-based diet, the better off we will be.” We know that the closest that we could possibly get would be 100% of our calories from those healthiest of foods.

So, for our 4Leaf Program, we set the top bar at 80%—meaning that if you consume 80% or more of your calories from whole plants, you’ll be eating at the 4Leaf level. From 60 to 79%, the score is 3Leaf and so forth. So where do most people score? How healthy is the typical Western diet?

Someday, this survey will be on a 4Leaf app for smart phones.

Our standard American diet is not very healthy. Most people in the USA and other Western countries are consuming the very un-healthy “typical Western diet,”  with meat, dairy, eggs and refined carbs at every meal. As you might guess, this harmful  diet does not score well on our 4Leaf scale.

We see six overall levels of eating—with the majority of the people not yet eating at the higher end of the scale—beginning with the 2Leaf level. With more information, we find that most people will voluntarily make improvements in their diet. Here’s our estimate of how the population of the USA is currently eating:

  1. 4Leaf level1% of the population (80 to 100% from whole plants)
  2. 3Leaf level—2% of the population (60 to 79% from whole plants)
  3. 2Leaf level—3% of the population (40 to 59% from whole plants)
  4. 1Leaf level—4% of the population (20 to 39% from whole plants)
  5. Better than Most—25% of the population (10 to 19% from whole plants)
  6. Unhealthy Diet—65% of the population (less than 10% from whole plants)

What about vegetarian? Is that 4Leaf? Not necessarily. Some vegans and vegetarians consume a very small percentage of their calories from whole plants. Although they’re not eating animal flesh, they’re getting most of their calories from refined carbohydrates (white pasta, bread, etc.), olive oil, cheese, salty snacks, soda—and none of those are health-promoting foods.

The key to vibrant health is consuming lots of the healthiest foods…whole plants.

Our survey measures what you ARE eating. It was designed to assess the approximate percentage of your calories that are derived from whole plants. The higher that percentage, the greater your chances of achieving vibrant health—while providing your body with the maximum amount of protection from chronic disease.

The Bottom Line. We know that everyone may not care about reaching the 4Leaf level of eating. But, for those who do, we think that this incredibly simple tool will help. Check out this feedback from a reader on 3-27-12, just two months after reading our book:

Mr. Hicks, It is with pleasure that I fill out the surveys again. We are now solid 3Leaf-ers and very proud!  My husband, at first, was just a hostage to my cooking, but he has come around.  He now orders only veggies even when we go out to dinner.  I am totally committed.

We do still add milk to our coffee.  It amounts to approx 4 TBS/day of 1%.  We have switched to Almond Milk instead of dairy with meals. Our blood tests came back yesterday….my total cholesterol dropped 51 points from 202 to 151.  Dave’s dropped from 182 to 159.

Since we read your book, our goal has been to eat better for ourselves and our planet.  I think we are achieving this….even though I see spots that can certainly be improved upon.  One is milk with coffee.

Thanks for the improved survey, it makes much more sense to me and enables me to see the “holes” that I need to fill. Best, Darcy

    Another informative article with charts that can be printed out for reference and to be shared. The following link also shows how one might rate their diets. At about 31:00 to 38:00 various foods are listed. Take the time to see the whole lecture. There are four others that might also interest individuals.
