PrimaFoodie Ingredient Spotlight: Sodium Benzoate

in

Additives in food are as ubiquitous as they are nebulous. That’s why we investigate common food fillers, preservatives, emulsifiers, and more to discover their origin, use, and purpose. Because if something is edible, that doesn’t guarantee it’s healthy or necessary.


What Is Sodium Benzoate?

Sodium benzoate is a lab-made odorless, flavorless, colorless, water-soluble crystal preservative commonly added to food and personal care items. As the 'sodium' in its name suggests, it is salt-based and made by combining sodium hydroxide, also called lye, and benzoic acid, a naturally occurring substance found in foods, including cranberries.

What's the Purpose of Sodium Benzoate?

A strong antimicrobial, sodium benzoate extends the shelf-life of food and personal care products by warding off the growth of bacteria and fungus. Commonly used in foods that have high acidity, such as salad dressings, juices, and pickled vegetables, sodium benzoate also enhances certain flavors. 

Where is Sodium Benzoate Found?

Since it is both a preservative and a flavor enhancer, food manufacturers add sodium benzoate to many processed and packaged foods, including:

  • Pickles

  • Canned vegetables

  • Salad dressing

  • Mustard, ketchup, and other condiments

  • Soda

  • Fruit juice

  • Jam, jelly, and other fruit preserves

  • Beer and wine


Sodium benzoate is also added to pharmaceuticals and personal care items, including: 

  • Lotion

  • Face cream

  • Soap

  • Serum

  • Shaving cream

  • Shampoo

  • Conditioner

  • Hair spray

  • Makeup

  • Lip balm

  • Toner

  • Various pharmaceutical pills


Is Sodium Benzoate Bad?

The FDA deems sodium deems sodium benzoate safe safe when it is added to food "at levels not to exceed good manufacturing practice." In essence, this means it is not to rise above 0.1 percent of a food's capacity. Furthermore, the Environmental Working Group sodium benzoate ranges from a low to moderate concern. 

Advanced scientific and medical research underscores both positive and negative outcomes when looking at sodium benzoate's impact on our health. A 2002 paper published in the open-access journal Nutrients states that sodium benzoate may show promise in treating "depression, pain, schizophrenia, autism spectrum disorders, and neurodegenerative diseases." Yet other researchers link sodium benzoate to "mutagenic effects, generate oxidative stress, disrupt hormones, and reduce fertility." 


The PrimaFoodie Take

Countless packaged foods contain ingredients we don’t know much about, which may harm our health. This goes for all foods that contain sodium benzoate. It is such a widely incorporated and undetectable preservative that it goes unnoticed even by the most discerning palate. Hands down, we are wary of this additive, so we avoid it. 

Firstly, if a food has sodium benzoate, it is processed (or ultra-processed), which is never good. Secondly, the studies mentioned above, combined with the fact that sodium benzoate is a robust antimicrobial agent, make us pause to consider this: If it’s wreaking havoc on bacteria, it’s likely doing the same to our microbiome. Plus, even if the FDA mandates safe levels of sodium benzoate, the harm comes from consistently eating it, thus allowing it to accumulate in our bodies. 

So, our take? We steer clear of sodium benzoate. 



PrimaFoodie Ingredients Spotlight: Soy Lecithin

in

Additives in food are as ubiquitous as they are nebulous. In our Ingredients Spotlight, we investigate common food additives to discover their origin, use, and purpose. Because just because something is edible doesn’t mean it’s healthy—or necessary.

What Is Soy Lecithin?

If you’ve eaten chocolate, you’ve likely consumed soy lecithin. A common ingredient, soy lecithin is a food additive derived from soybeans. 

There are various types of lecithin. A mixture of phospholipids, lecithin is a fatty substance naturally found in plant and animal cells and tissues. Common sources of lecithin include sunflower seeds, eggs, and cotton seeds. Here we break down soy lecithin, which comes from soybeans. 

What Is the Purpose of Soy Lecithin?

Food manufacturers use soy lecithin to emulsify ingredients so they become stable, smooth, and homogenized. Naturally amphiphilic (containing water soluble and insoluble chains), soy lecithin provides a way to easily blend ingredients that normally wouldn’t mix, such as oil and water. It’s also a common flavor protectant and taken as a dietary supplement.

Where Is Soy Lecithin Found?

Soy lecithin is commonly found in products that have a smooth and creamy consistency. These include:

· Bread

· Chocolate

· Dressings and marinades

· Packaged food

· Alternative milk

· Cereals, pasta, and other processed grains

· Cooking sprays 

· Ice cream, puddings, and other dairy products

· Nutritional supplements and vitamins

Is Soy Lecithin Bad?

This is the million-dollar question. Manufacturers claim that since soy lecithin is usually added in small doses, it isn’t harmful. But consider this: Those “small” doses add up. Plus, soy lecithin is ubiquitous these days (it’s hard to find even a natural dark chocolate bar without it), which poses the potential of consuming it consistently. Research has shown that ingesting the same additives over and over can lead to systemic inflammation, gluten intolerance, and other food sensitivities. 

There is also a critical conversation around soy. Those who have soy allergies should avoid soy lecithin. Yet, allergies aside, it’s important to consider that soy is often genetically modified and rarely organic, which means the original source of the lecithin could be covered in pesticide and herbicide residue.

Lastly, removing soy lecithin requires a process that involves a harsh solvent called hexane. A potential carcinogen, hexane has been shown to damage reproductive organs and fetal health, cause skin irritation, and pose a hazard to the lungs if inhaled. The FDA does not regulate the residual hexane in foods.

Soy Lecithin: Other Options

Because soy lecithin provides a way to emulsify fats with water, it’s commonly used. But that doesn’t mean it’s necessary. Soy lecithin is an industrial additive. In short: It is always best to avoid anything industrial, mass-produced, and added. Aim for real, whole foods with as few ingredients as possible. Avoiding soy lecithin—or any lecithin—is a way to decrease the number of adulterated additives entering the body. 

Deciding whether to consume soy lecithin is a personal choice. It’s important to always read labels to see if soy lecithin is present. Many food companies are creating products without it. HU Chocolate, for one, is manufacturing cleaner chocolates free of lecithins (soy or any kind), processed sugars, colorings, and other additives.
