Does your food nourish you—
or just claim to?
Labels can say organic, natural, or fresh, but that doesn’t guarantee what your body is actually receiving. The truth is, much of our modern food looks alive but is nutritionally hollow—grown in depleted soil, bred for shelf life over substance. You can’t always see the difference, but you can taste it. And more importantly, your body can feel it.
That’s where the Bionutrient Food Association steps in.
We’re building a new food culture rooted in nutrient density, soil health, and transparency. By supporting growers, educating consumers, and even developing tools to measure real nutritional value, BFA is helping you reconnect to what food is meant to be: nourishing, vital, and alive. Because it’s not just about what you eat—it’s about what that food was fed long before it reached your plate.
NEW! - Bionutrient BRIXit Kit!
You already know some produce just tastes different. Sweeter. More alive. Like it actually came from the ground and not a warehouse.
The BRIXit Kit gives you the tool to prove it.
Using a simple handheld refractometer, you can measure the BRIX score of fruit or vegetable juice — a number that reflects the sugar and mineral density in your food. Higher BRIX generally means more flavor, more nutrition, and healthier soil. Lower BRIX means the opposite.
It takes about 60 seconds. No lab required.
What's inside:
Handheld BRIX refractometer
BRIX press coin for easy juice extraction
BRIX reference chart
Step-by-step instructions
How it works:
Pick your produce. Squeeze a drop of juice onto the refractometer's glass plate. Look through the eyepiece. The number where blue meets white is your BRIX score. Log it. Compare it. Share it.
Why it matters beyond your kitchen:
Every score you log through the BRIXit app becomes part of a growing dataset — built by people like you, for people like you. Over time, those readings reveal which farms, stores, and regions are consistently producing nutrient-dense food. Your shopping trip becomes a data point that helps your whole community eat better.
Who it's for:
The person who reads the label and asks where it was grown. The parent who drives across town for the good eggs. The cook who knows the difference and wants to stop guessing.

The direct soil Electro-Conductivity Meter is an essential tool for the grower to have in their toolbox. Soil electrical conductivity (EC) is a measure of the electrical charge in the soil, where too much or too little can hinder optimal plant growth. The measure of conductivity provides a valuable indicator of soil health and the functioning processes foundational to crop quality and yields, plant nutrient availability, and activity of soil microorganisms. The EC meter provides the grower with a critical snapshot that underpins the health of their soil, and is useful for addressing shortcomings or adjusting strategies in the growing season.
This meter is rugged and reliable, and pocket-sized for easy transport and field application, offering quick and accurate readings. This tool features a stainless steel penetration probe for direct measurement.
Product Specs:
• Waterproof
• Replaceable 4.5 inch penetration electrode
• Automatic temperature compensation
• Manual calibration in an aqueous solution to a single point

Refractometer, Vise/sap press & Brix Chart
The refractometer in our Brix Kit is currently the most accessible of tools available for discerning quality. While not a measure of nutrient density, it is generally understood that the refractive index, or brix, of a given fruit or vegetable correlates closely to quality and taste. Refractometers are an easy, low-cost test widely used among growers for whom quality is important. But you don't need to be a farmer - you can just as easily use a refractometer on produce you buy from the store to get a better undertanding of what you are eating, or who has the best carrots at the market.
We offer products to help you prepare the soil, test plants, and produce quality food that is nutritious and fit for human consumption. These products have been curated by Dan Kittredge himself, with great attention taken to finding the best quality available. These are the same products he uses on his own farm.

We work to support growers in changing their management practices to improve the quality of food they produce.
We seek to support, educate, organize and empower farmers, scientists and leaders in building human and planetary vitality through the principles of life and nature.
Together, we are stewards of our food future.
Through founding The Bionutrient Institute, we work with a network of labs to access food, crops & management practices in a survey of the food supply broadly. We understand through this work that massive variation exists in the food supply. We understand science to be a means to understand this variation & improve our practices globally.
The BFA is a membership organization that seeks to support depth of understanding and community through our annual Soil & Nutrition Conference, courses and on-farm consultation. Learn how to become a member of this vibrant community here.
We work to support consumers and growers of food in determining which food is nutritionally superior, and guidance on growing it. To further achieve this, we’ve developed a handheld Bionutrient Meter that, with a flash of light, can offer nutritional information about food, crops and soil. Our job now is to complete the research in order to create a 1-100 scale for food quality. We need the science in order to calibrate the meters.
