Exploring the Healthiest Salt from Mexico: A Guide to Unrefined Options

January 12, 2026 •

4 min read

According to a study cited by Doctor Kiltz, 90% of all sea salt tested has been found to contain microplastics, highlighting the importance of sourcing from pristine environments. When it comes to finding the healthiest salt from Mexico, the answer lies not just in its origin, but in the traditional, unrefined harvesting methods that preserve its natural mineral profile and purity.

Quick Summary

This article compares mineral-rich Mexican salts, examining harvesting techniques, mineral content, and overall purity. It focuses on hand-harvested, unrefined options like Colima and Baja Gold, explaining how their production methods and mineral profiles contribute to a healthier seasoning choice for mindful cooking.

Key Points

Unrefined is Healthier: Unrefined salts, like Colima and Baja Gold, retain natural minerals and avoid harsh processing, unlike table salt.
Colima Salt's Volcanic Purity: Hand-harvested from a volcanic-filtered lagoon, Colima sea salt is naturally rich in minerals and free from microplastics.
Baja Gold's Mineral Spectrum: Harvested from the Sea of Cortez, Baja Gold offers a comprehensive trace mineral profile and naturally lower sodium levels.
Additives are a Red Flag: To ensure you're getting a pure product, check labels for unrefined salt and avoid those with anti-caking agents.
Support Sustainable Traditions: Choosing artisanal, hand-harvested Mexican salts supports traditional communities and environmentally respectful practices.
Beyond Sodium: The health benefits of unrefined Mexican salts stem from their trace mineral content, which aids in hydration and electrolyte balance.

The Search for Purity: Defining 'Healthiest'

When evaluating what constitutes the 'healthiest' salt, several key factors come into play. A truly healthy salt should be minimally processed, retain its natural trace mineral content, and be free from contaminants like microplastics and harsh additives. Industrially produced table salt is often stripped of its minerals and can contain anti-caking agents, making unrefined sea salts a superior alternative. In Mexico, several artisanal salts meet these criteria, with Colima and Baja Gold being two standout examples, offering distinct profiles shaped by their unique origins and traditional harvesting methods.

Colima Sea Salt: Volcanic Filtration and Mineral Richness

Harvested for over 500 years from the Laguna de Cuyutlán in the state of Colima, this salt is a testament to traditional, sustainable practices. The water is naturally filtered through volcanic earth, which enriches the brine with a wealth of trace minerals before it is evaporated by the sun. The entire process is hand-harvested, resulting in a coarse, moist, and flaky salt free from microplastics and other pollutants. Its rich mineral profile, including magnesium, potassium, and calcium, contributes to a clean, briny flavor that enhances rather than overpowers food.

Baja Gold Sea Salt: A Comprehensive Mineral Profile

Sourced from the pristine Sea of Cortez, Baja Gold is another top contender for the healthiest Mexican salt. It is marketed as having a comprehensive mineral and trace element profile and a notably lower natural sodium chloride level than many other salts. This is due to its natural, unrefined harvesting process. Baja Gold is a great choice for those seeking a broad spectrum of minerals for enhanced taste and vitality. The salt is simply dried by the sun, preserving its natural benefits.

Other Mexican Salts: Variety and Tradition

While Colima and Baja Gold represent peak purity and mineral content, other Mexican salts offer unique flavors and profiles. Sal de Pueblo from Puebla, for example, is a low-sodium, mineral-rich option derived from ancient fossil properties. Specialty salts like Sal de Gusano (worm salt) from Oaxaca, made with ground agave worms and chiles, are more about specific culinary flavor and tradition than general health, though insects themselves can offer nutritional benefits. Ultimately, the healthiest choice depends on your specific needs, but focusing on unrefined, hand-harvested options is the most reliable strategy.

Mexican Salts at a Glance: Colima vs. Baja Gold vs. Table Salt


Feature	Colima Sea Salt	Baja Gold Sea Salt	Processed Table Salt
Origin	Laguna de Cuyutlán, Colima, Mexico	Sea of Cortez, Baja California, Mexico	Underground salt deposits or seawater; industrialized
Processing	Hand-harvested, sun-dried, volcanically filtered	Hand-harvested, sun-dried, minimally processed	Heavily refined, bleached, and heat-treated
Mineral Content	Rich in magnesium, potassium, calcium, and trace minerals	Comprehensive profile of 72+ minerals	Contains primarily sodium chloride; natural minerals are stripped
Microplastic Risk	Extremely low; sourced from inland, protected lagoon	Low; sourced from a pristine marine area	High; significant risk due to industrial harvesting from oceans
Sodium Level	Balanced mineral blend, not just sodium chloride	Naturally lower in sodium chloride	Very high, up to 99% sodium chloride
Best Use	Finishing salt, cooking, hydrating drinks	Everyday cooking, finishing, mineral supplementation	General cooking where flavor complexity isn't a priority

How to Choose the Right Mexican Salt for Your Health

Selecting a healthy salt involves being a mindful consumer. Always read labels to ensure the salt is unrefined and doesn't contain anti-caking agents or other additives. Transparency from the producer about their sourcing and harvesting methods is a great indicator of quality. If you're looking for a finishing salt with a distinctive crunch, Colima sea salt is an excellent choice. For daily cooking and a balanced mineral intake, both Colima and Baja Gold offer significant benefits. These choices not only offer potential health advantages but also support traditional, sustainable practices. Ultimately, moving away from heavily processed table salt to a whole, unrefined Mexican sea salt is a simple yet impactful step towards healthier eating.

The Takeaway: It's All in the Processing

While no salt can be definitively crowned 'the healthiest' without specific nutritional data, unrefined, hand-harvested salts like Colima and Baja Gold are clearly superior to heavily processed alternatives. Their rich mineral content, purity, and traditional harvesting methods ensure a cleaner and more flavorful product. The unique volcanic filtering of Colima salt and the comprehensive profile of Baja Gold make both excellent choices. When you choose an authentic Mexican sea salt, you are not just seasoning your food but adding a layer of mineral-rich flavor and supporting a legacy of environmental respect and craftsmanship.

Frequently Asked Questions

Unrefined sea salt is healthier because it retains its natural trace minerals like magnesium, potassium, and calcium, which are often stripped away during the heavy processing of table salt. It also lacks anti-caking agents and other additives.

Colima sea salt is a product of the sea, hand-harvested from a coastal lagoon and naturally filtered through volcanic earth, making it free from microplastics. Himalayan salt is mined from ancient, fossilized salt deposits and can have a different mineral profile and origin story.

Not all. While traditionally harvested artisanal salts from protected inland lagoons, like Colima, are considered microplastic-free, industrially produced sea salt from general ocean sources carries a risk of microplastic contamination.

Look for labels that state the salt is 'unrefined,' 'hand-harvested,' or 'sun-dried' and check for a list of ingredients. A pure, unrefined salt should list only salt and not contain any anti-caking agents or added iodine.

The trace minerals, such as magnesium and potassium, found in unrefined Mexican sea salts aid in hydration by balancing electrolytes. These minerals also support proper muscle function, nerve impulses, and overall vitality.

Clumping is a normal and good sign in unrefined sea salt. It happens because the salt retains its natural moisture and trace minerals. Since it does not contain industrial anti-caking agents, occasional clumping is expected.

Sal de Gusano, or worm salt, is a traditional Oaxacan seasoning made with ground agave worms, chilies, and salt. While it offers unique flavor and some nutritional benefits from the insects, it is primarily used as a culinary specialty for agave spirits rather than a general health-focused salt.
