Hey Y'all,
It’s one of those fascinating questions that often comes up during tastings or wellness chats: Does your blood type influence which water you should drink? Can someone with Type O benefit more from a magnesium-rich sparkling water, while someone with Type A might need a low-sodium, still option?
Let’s dive into the science, the myth, and the mineral truth — because at Salacious Drinks, we believe every sip tells a story. But not all stories are backed by science.
The Origins of the Blood Type Diet Theory
This idea became popular in the late 1990s, largely thanks to Dr. Peter D’Adamo’s book “Eat Right 4 Your Type.” In it, he proposed that our blood types — A, B, AB, and O — dictate how we process foods, exercise, and even handle stress. According to this theory:
-
Type O thrives on protein and vigorous movement.
-
Type A does better with plant-based foods and calming practices.
-
Type B has a more omnivorous, balanced tolerance.
-
Type AB is complex, blending traits of A and B.
The theory suggested that lectins (a type of protein found in many foods) interact with blood antigens differently — which, if true, could influence everything from food digestion to inflammation.
However, here's the twist: multiple peer-reviewed studies have found no scientific evidence that blood type diets improve health outcomes. In 2014, a study published in PLOS ONE concluded that while certain diets may benefit cardiovascular health, “these benefits are independent of an individual’s ABO genotype.” So the diet itself might help you — but not because of your blood type.
But What About Water?
Here’s where things get even murkier. Dr. D’Adamo didn’t dive deep into specific water types in his books. There’s no official guidance in his theory on whether mineral content, effervescence, or pH should vary depending on your blood type.
But as a certified water sommelier (and someone who spends her life surrounded by glass bottles from the far corners of the earth), I’ve seen people respond differently to water — just not because of their blood type.
Instead, it comes down to:
-
Your health status (do you have high blood pressure, kidney issues, digestive sensitivities?)
-
Your activity level (do you sweat a lot or need muscle recovery?)
-
Your climate (are you in dry heat, cold weather, or humid conditions?)
-
Your stress (minerals like magnesium and bicarbonate help soothe nerves and support gut health)
The Real Way to Match Your Body with Your Water
While we can’t match you to a bottle by blood type, we can help you listen to your body and drink with intention. Here are a few examples:
🧠 For Stress and Recovery:
High Magnesium Waters
-
Examples: Borjomi (Georgia), Three Bays (Australia)
-
Helps with nerve function, muscle tension, and quality sleep
💧 For Kidney Health and Detox:
Low Mineral, Silica-Rich Waters
-
Examples: Fiuggi (Italy), Socosani Spring (Peru)
-
Gently hydrates and may assist with waste elimination
🧂 For Heavy Sweaters or Athletes:
Sodium + Bicarbonate-Rich Waters
-
Examples: Vichy Catalan (Spain), Topo Chico (Mexico)
-
Replaces lost electrolytes and supports digestive pH
🍽 For Digestion:
Effervescent Waters with Bicarbonate
-
Examples: Saint-Géron (France), Ferrarelle (Italy)
-
Helps ease bloating and enhance mineral absorption
💅 For Beauty and Skin:
Silica-Rich Waters
-
Examples: Acqua Panna (Italy), Fiuggi (Italy)
-
Supports collagen formation and skin elasticity
Final Verdict: Your Blood Type Isn’t the Key. Your Lifestyle Is.
So while it’s intriguing to think your blood type holds the hydration key, there’s no scientific link between blood type and the ideal bottled water. What does matter is the story your body is telling today — are you tired, bloated, sore, stressed, or simply thirsty?
