PrimaFoodie Ingredients Spotlight: Soy Lecithin
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.
