Soy lecithin safety?


Hi Debra,

I try to limit my soy consumption because of the phytoestrogens and I have read that the grade of soy used in processed foods such as nutrition bars is not of a high quality and actually leftover product. Unfortunately, I have found soy lecithin in products almost to be impossible to avoid. Is soy lecithin a phytoestrogen? If a lot of products that I use contain soy lecithin as an emulsifier, even if it is only a small amount wouldn’t the small amount in each product add up day after day? I typically choose products with as few ingredients as possible, but many, such as bread, still use soy lecithin as the emulsifier. Furthermore, if the soy used in commercial products is not of a high quality, I would imagine the lecithin is not either. Thanks.

I'm just going to answer this from my own experience. A more definitive answer may be in the book The Whole Soy Story, but my copy is in Florida and I'm in San Francisco at the moment.

I avoid soy for the same reason--soy really messes up my hormones. However, I've found over the years that I don't need to avoid either lecithin or soy sauce. They just don't react in my body the way other soy products do. I really need to stay away from tofu, for example, and don't eat protein bars with soy (well, I actually don't eat protein bars at all).

You need to observe for yourself if lecithin seems to cause harm to your body or not, as all bodies are individual.

I know I may sound like a broken record on this point this week, but this is yet another reason to cook for yourself!

Soy lecithin is differed to soy isoflovones.

Isoflavones is plant hormones which is related to sex hormones.

Soy lecithin is a lipid which is important for health, your body need it. your liver can make it if you are in good nutritional condition. It has important role in fat digestion, in lovering blood cholesterol level profile, building block of cell membrances (therefore important to brain, organs, & skin, etc.

It also is one of the component of bile acid, lack of it can cause gall stone.

For many poeple have cholesterol problem, supply with soy lecithin, it often help normalize their blood cholesterol levels.
It is an unsaturated cpd, therefore easily be oxidized become toxic radical when expose to heat, light & O2, or auto-oxidize in long storage.

Supplementation of soy lecithin for lower cholesterol, or choline demand must takeing VitE to preventing oxidation.

food industry use it as emulsifier for forulation purposes.
