If carbohydrates are high in deuterium…
And high deuterium damages mitochondrial nanomotors…
Then why are super centenarians in the Nicoya Peninsula in Costa Rica eating rice and beans — and living past 100?
This is the question Dr. Laszlo Boros — Hungarian medical doctor, retired professor at UCLA School of Medicine, author of 100+ peer-reviewed papers and one of the world's leading deuterium researchers — was asked by @thelightdiet if carbohydrates are high in deuterium…
And high deuterium damages mitochondrial nanomotors…
Then why are super centenarians in the Nicoya Peninsula in Costa Rica eating rice and beans — and living past 100?
His answer reframes everything about longevity, diet, and deuterium depletion.
They're not avoiding deuterium through diet.
They're depleting it through biology.
Five synchronized mechanisms — all of which modern humans have largely destroyed.
1. Nutritional metabolic ketosis (via the microbiome)
These populations eat carbohydrates.
But their highly adapted microbiome ferments those carbohydrates into short-chain fatty acids — butyrate, propionate — that are deuterium-depleted relative to the original substrate.
Their gut bacteria eat the high-deuterium carbohydrates and hand the human host low-deuterium ketone bodies.
They are operating in a state of nutritional ketosis — without eating a ketogenic diet.
The bacteria do the depletion for them.
2. The biological cost — stool volume and skin shedding.
The deuterium has to exit somewhere.
Boros: "You need to look at their stool. Their stool is probably larger, it's more volume, and it's more deuterium-packed."
The dead, deuterium-loaded bacteria leave through the gut.
These populations produce significantly larger stool volumes and have more frequent bowel movements than carnivore populations — who may only use the bathroom once or twice a week.
The stool is the primary exit route for the deuterium they consumed.
This is the biological cost of carbohydrate-based deuterium management.
But stool is not the only exit route.
Intense sunlight accelerates the rapid turnover and shedding of keratinocytes — skin cells.
The skin becomes another active deuterium excretion pathway.
Boros: "Your skin actually produces and depletes deuterium on a constant basis simply because you produce keratinocytes, especially when you're exposed to sunlight."
Which brings us to the next point.
3. Sunlight
Most of these super centenarian populations live close to the equator.
Intense red and near-infrared photon pressure penetrates tissue and reduces the viscosity of structured water inside the mitochondrial matrix — allowing nanomotors to keep spinning efficiently even when dietary deuterium is slightly elevated.
The light and the local food work as a synchronized package.
Boros: "You actually deplete deuterium very efficiently in your local environment once you encounter the appropriate microbiome for it."
4. Intergenerational microbiome sharing
The ancestral tribes often eat the exact same local foods their ancestors ate for generations.
They live in close physical contact — carrying adapted bacteria on their bodies, passing them to offspring through direct contact.
Generation after generation of the same local food plus the same specialized deuterium-depleting microbiome.
Boros: "They give these bacteria to one another because they are in close contact with their offspring. They carry them on their body. They actually get in contact with their stool and everything. Practically they are very efficient in providing one another a deuterium-depleting microbiome."
5. Night-cycle plant biology — the plants themselves are depleted
This is the mechanism most people miss entirely.
The specific rice and beans these populations eat are locally grown, non-GMO plants — and those plants are naturally deuterium-depleted at specific carbon positions.
The mechanism: during the night cycle, plant chloroplasts act like mitochondria — producing sugars that are naturally depleted of deuterium at the 3rd and 5th carbon positions of the sugar molecule.
Boros: "If you look at some papers that discuss the deuterium content in carbohydrates — for example, the fifth and the third carbon of sugar in beans which are grown in a natural environment — they are actually pretty depleted of deuterium simply because they use the night cycle when they use their chloroplasts as mitochondria."
Modern industrially farmed GMO crops have been engineered to grow faster — destroying this natural night-cycle deuterium depletion mechanism entirely.
The carbohydrate looks the same. The deuterium content is not.
The modern contrast
You cannot copy the tribal diet without copying the tribal biology.
Glyphosate, antibiotics, and processed food have destroyed the first line of microbial deuterium defense.
Artificial blue light has replaced the equatorial photon pressure that compensates for dietary deuterium.
Industrial GMO food has replaced locally grown, seasonally consistent food sources.
Sterilized environments have broken intergenerational microbiome transfer.
A modern human eating rice and beans does not have the biological machinery these populations built over generations.
Boros's conclusion:
“If you're able to stay in your local environment and not ship in food with unknown deuterium content. You can actually be safe on a relatively carbohydrate-rich diet if the carbohydrate portion of your diet is deuterium-depleted — and that's the case with plants which are not GMO."
The Nicoya centenarians are not evidence that carbohydrates are uniformly safe for modern humans.
They are evidence that deuterium depletion is a whole-system biological problem — not a dietary one.
Fix the environment.
Not just the diet.
