Nutritionists and Health influencers have hard time reaching a consensus regarding what we should eat to thrive and optimize our Health.
Fact is that we are overloaded, fed (up) with a plethora of contradictory information, sometimes genuinely brought to us but most often marketing driven
In the internet arena, the fight oppose advocates of Veganism, Alkaline Diet, Atkins, Dairy / Gluten Free, FODMAP, IIFYM, Nutritarian, Paleo, Pegan, Pescetarian, Primal, Raw, Slow / Low Carb, Trim Health Mama, Zone diet, Whole 30,….enough ?
So who’s right and where should we fit ?
Truth is that we’re all different. Our specific DNA blueprint clearly plays a role but maybe not as much as our exposome that accounts for all external environmental and internal factors such as your microbiome that will alter the way your body react to a particular food signal
At such, Weizmann Institute (Israel) conducted an interesting tracking study on 800 people showing that individual blood sugar level would react differently to an exact same food, proving that there’s no such thing as a one size fits all diet
But looking deeper, filtering through all the existing diets promoted in TV-shows, best-selling books, brands, ™ , ® , www or @, a convergence point can actually be found
A proper and optimized diet should:
Improve your antioxidant level and limit the oxidative stress incurred to your body.
At such, most antioxidants are derived from eating the right amount of fruit and vegetables, from real, non-processed, non-refined plants and specific animal foods. Reducing the oxidative burden of food is more complex and can sometimes offset the beneficial intake of antioxidant.
Ironically, as of today, 2016, we still rely, blindly, on our feeling or physical shape to validate / unvalidate our eating behavior. A kind of… shot in the dark
But, as the maxim goes: you can only improve what you get measured
Now, what if deep inside your skin, there was something that your body wanted to tell you ?
Enter Skin carotenoids
Dozens of peer reviewed studies (here, here, or even here) have concluded that skin carotenoids are the most objective biomarkers to assess people intake of fruits and vegetables (See our own study). The National Academy of Sciences actually states that ”Carotenoid concentration is the best biological marker for consumption of fruits and vegetables.” (1)
Why are skin carotenoids so interesting ?
Carotenoids are a crucial type of antioxidants along with specific vitamins (A, C, E) minerals (zinc, selenium) and other phytonutrients (flavonoids) that play indirect antioxidant role.
They can only be obtained through proper nutrition.
Carotenoids are specific yellow, orange and red pigments synthesized by plants. They can also be found in dark leafy greens such as spinach and kale and green veggies such as broccoli and peas. In fact, more than 750 carotenoids are present in human and food complex but 5-10 of them are known to play a critical role. (b-carotene, a-carotene, b-Cryptoxanthin, Lycopene, Lutein, Zeaxanthin, Astaxanthin) :
Carotenoids play a central role in the antioxidant matrix
Skin carotenoids actually do not only reflect the consumption of rich carotenoid foods but consumption of rich antioxidant foods in general since antioxidants act in team and help each other to be regenerated (“reduced”) once they have been oxidized to neutralize and fight damaging free radicals
One X team has reconstructed a map of how your body antioxidant collaborate:
As you can see: beta carotene and lycopene (the two major carotenoids measured by One X in your skin) are strongly influenced by other antioxidants, not only by those absorbed from food (Vit, C, E, A, flavonoids) but also by powerful enzymatic antioxidants directly produced by your body such as glutathione. That’s why One X score is such a powerful indicator of the quality of your diet.
Not merely what you eat but what your body effectively absorbs
One X brings the answer, in the palm of your hand
As you’ll discover in details in the upcoming blog posts, One X score is actually influenced by many of your lifestyle habits (cf..) but nutrition remains the key element that influence your antioxidant status.
One X combines a sensor that non-invasively tracks your skin carotenoid concentration paired with a mobile app that uses advanced computer vision algorithms to track your food intake so you can understand and custom your nutrition to optimize your antioxidant protection.
Now, you know…
