Understanding the Veggie Meter's Scoring System
The Veggie Meter is a portable, non-invasive device that uses reflection spectroscopy to measure carotenoid concentrations in the skin, usually on the palm or fingertip. Carotenoids are potent antioxidants found in colorful fruits and vegetables, and their concentration in the skin serves as an objective biomarker for recent dietary intake. The final score, which is an average of three separate scans, ranges from 0 to 800. Unlike other assessment methods that rely on potentially biased self-reported data, the Veggie Meter provides a more objective measure of your consumption habits over the preceding weeks.
Interpreting the Score Ranges
The most commonly referenced scores from research and clinical settings offer a clear guide to interpreting your results.
- Red, Orange, or Yellow Zone (Lower Scores): Scores in this area generally indicate low skin carotenoid levels and a need to increase fruit and vegetable intake. For example, one study found a mean score of 270 among a sample of adults, with those consuming less than three cups of fruits and vegetables daily having lower average scores. Scores at the lower end of the scale may correspond to a below-average consumption of carotenoid-rich foods.
- Green or Blue Zone (Higher Scores): Falling into these zones signifies a healthy intake of fruits and vegetables. Research has identified specific healthy ranges; for instance, some studies suggest a healthy score is between 280 and 480. Higher scores are positively correlated with a greater daily intake of produce and demonstrate higher antioxidant stores in the body.
Factors That Influence Your Veggie Meter Score
While the main driver of your score is fruit and vegetable consumption, several other factors can affect the reading. Researchers document many of these variables to ensure accurate study results.
- Dietary Habits: The total volume and type of fruits and vegetables consumed are the primary factors. Eating more carotenoid-rich produce, like spinach, carrots, and sweet potatoes, directly boosts your score. Inversely, some studies have noted that higher soda intake is associated with lower scores.
- Physiological Characteristics: Factors like Body Mass Index (BMI), age, and biological sex have been shown to influence carotenoid levels. For example, studies have observed a negative correlation between BMI and skin carotenoid scores.
- Lifestyle: Smoking and sun exposure can also impact your reading. Smoking is linked to lower skin carotenoid levels.

How to Improve a Low Veggie Meter Score
Improving your score requires consistent, deliberate changes to your diet to increase your intake of carotenoid-rich foods. These changes typically reflect a more balanced, nutrient-dense eating pattern.
Strategies to Boost Your Score
- Increase intake of colorful produce: Focus on fruits and vegetables with red, orange, and dark-green colors. This includes carrots, sweet potatoes, spinach, kale, bell peppers, tomatoes, and watermelon.
- Drink carotenoid-rich juices: Vegetable juices like V8 can be an effective way to increase carotenoid consumption, as shown in clinical trials.
- Eat consistently: A six-month educational program involving monthly produce boxes and Veggie Meter readings showed that regular access to fruits and vegetables led to significant score increases.
- Avoid negative dietary habits: Limit your intake of foods with low nutritional value, such as sugary sodas, which have been shown to correlate with lower scores.
Making Lasting Dietary Improvements
Long-term improvements require more than just a temporary diet change. They involve integrating sustainable, healthier habits into your daily life. Family-based interventions are particularly effective, as children's fruit and vegetable intake is often influenced by their parents' habits. Tracking progress with a tool like the Veggie Meter can also provide motivating feedback. For more detailed information on carotenoids and diet-related health outcomes, you can review the National Institutes of Health recommendations.
Conclusion
For anyone asking what is a good score on the Veggie Meter, the answer points toward the "green" and "blue" ranges, with specific clinical ranges suggesting scores between 280 and 480 as healthy. The score is a powerful, objective metric reflecting your intake of carotenoid-rich fruits and vegetables over the recent weeks. While a lower score simply indicates a need for improvement, consistent effort to boost your daily produce consumption can lead to noticeable increases in your reading and, more importantly, enhanced health. By understanding your score and making focused dietary changes, you can effectively work toward a more nutritious and well-rounded diet, celebrating progress along the way.

FAQs
What exactly does the Veggie Meter measure? The Veggie Meter uses light technology to measure the concentration of carotenoids, which are powerful antioxidant pigments, in your skin tissue. This measurement provides a reliable and objective indicator of your overall fruit and vegetable intake over the preceding 2–4 weeks.
Is the Veggie Meter a one-time test? No, the Veggie Meter is most effective when used for repeat measurements over time. Tracking your score allows you to see how your dietary changes, such as increasing produce consumption, are affecting your skin carotenoid levels.
How accurate are Veggie Meter scores? Studies have shown a strong correlation between Veggie Meter-assessed carotenoid levels and serum carotenoid concentrations measured through traditional, more invasive blood tests, validating its use as a measure of fruit and vegetable intake.
Can my skin tone affect my Veggie Meter reading? The Veggie Meter device includes an algorithm that corrects for variations in melanin concentration, the pigment that determines skin tone. This helps ensure that skin tone does not skew the results and that the score accurately reflects your carotenoid levels.
How quickly can my score change? Changes in diet can lead to measurable changes in your Veggie Meter score over a period of weeks. Interventions as short as six weeks have been shown to produce significant increases in scores in response to higher carotenoid intake.
Are all fruits and vegetables measured equally? The device primarily measures carotenoid levels, so foods rich in these compounds, such as carrots, sweet potatoes, spinach, and kale, will have a more significant impact on your score. Foods without carotenoids will not be reflected in the measurement.
Is there an age limit for using the Veggie Meter? The device has been used in research studies on a wide range of age groups, from preschool-aged children to older adults, proving its versatility as a tool for assessing dietary habits across a lifespan.
