Dr. Bill Schindler on the Ancestral Importance and Modern Understanding of Salt

The Ancient Significance of Salt

• 🌍 Salt has been incredibly sought after throughout human history, with migratory patterns often including stops at salt sources or trade routes.
• ⛏️ Archaeological and historical records consistently show salt's immense importance to human societies.

Understanding Dietary Salt

• 🧂 The term "sea salt" is considered misleading, as all dietary salt originates from the sea, whether from ancient underground deposits or current salt flats.
• ⏳ Key differentiating factors for salt include when it was in the sea, its refinement process, and any additives.
• 💎 The ideal salt is from an ancient sea with the highest mineral content and no additives.

Salt's Impact on Food Experience

• 👅 The shape and size of salt crystals significantly impact the sensory experience of consuming food.
• 🥨 Examples like mint chocolate chip ice cream and sourdough pretzels illustrate how different salt forms (morsels vs. slabs, kosher vs. pretzel salt) alter taste and texture perception.

Ancestral Uses of Salt

• 🍖 Salt was likely used by ancestors for preservation, nutrition, and taste.
• 🦌 It's also probable that salt was used to attract animals to specific locations for hunting, evidenced by elephants mining mineral-rich caves containing salt.

Choosing and Supporting Salt Sources

• 👍 From a nutritional standpoint, a high-quality source like Redmond salt is sufficient.
• 🤝 Economically, it's beneficial to support multiple suppliers doing good work in the food system, as they are fighting against large industries.
• 🚫 When purchasing salt, check the label for additives; ideally, the only ingredient should be pure salt.

Iodine and Iodized Salt

• ⚠️ The fortification of salt with iodine in the early 1900s was a response to widespread iodine deficiency due to less diverse diets, particularly in areas without seafood access.
• 🌿 Seaweed is a superior and more bioavailable source of iodine compared to iodized salt.
• ⚠️ While iodine is essential, supplementation should be done cautiously and with expert consultation, as it's possible to overdose on highly bioavailable forms.
• 🚫 Dr. Schindler avoids iodized salt, believing sufficient iodine can be obtained from a diverse diet.
