Sulfur ranks as the number three most abundant mineral in the body coming in after the minerals calcium and phosphorous. Almost half of the sulfur in your body is found in your muscles, bones and skin. Sulfur also plays a role in many of your body systems and consuming sulfur rich foods is important.
Sulfur represents about 0.25 percent of our total body weight, similar to potassium. The body contains approximately 140 grams of sulfur-mainly in the proteins, although it is distributed in small amounts in all cells and tissues. Sulfur performs a number of functions in enzyme reactions and protein synthesis. It is necessary for formation of collagen, the protein found in connective tissue in our bodies. As we age, the flexible tissues in the body tend to lose their elasticity, leading to sagging and wrinkling of skin, stiff muscles as well as painful joints. A shortage of sulfur may contribute to these age-related problems.
Sulfur also plays an important role in the following:
- Cellular respiration, as it is needed in the oxidation-reduction reactions that help the cells utilize oxygen, which aids brain function and all cell activity.
- Vitamin-B thiamine (B1) and biotin conversion which is required for converting carbohydrates into energy.
- Synthesizing glutathione. (See “importance of glutathione synthesization” below)
- Insulin function.
- Acts as the key agent in the effective utilization of amino acids. Four of the more crucial amino acids, methionine, cystine, cysteine, and taurine, cannot effectively function without organic sulfur.
The Power Glutathione Synthesization – Sulfur
Dr. Mark Hyman adequately sums up the importance of glutathione synthesization: Glutathione :The Master of All Antioxidants — “It’s the most important molecule we need to stay healthy & to prevent disease. It’s the secret to prevent aging, cancer, heart disease, dementia & more, & necessary to treat everything from autism to Alzheimer’s disease. The secret of its power is the SULFUR (SH) chemical groups it contains. Sulfur is a sticky, smelly molecule. It acts like fly paper & all the bad things in the body stick onto it, including free radicals & toxins like mercury and other heavy metals. Normally glutathione is recycled in the body — except when the toxic load becomes too great. This explains why we are in such health trouble & should consume more sulfur rich foods to support the body in healing and repair.”
Top Sulfur Rich Foods
Sulfur is readily available in protein foods such as meats, fish, poultry, eggs, milk, and legumes. Egg yolks are one of the better sulfur rich foods. Other foods that contain this somewhat stinky mineral are onions, garlic, cabbage, Brussels sprouts, turnips, nuts, kale, lettuce, kelp and other seaweed, and raspberries. Complete vegetarians (those who eat no eggs or milk) and people on low-protein diets may have difficulty in getting proper amounts of sulfur. It is important to note that the resulting sulfur deficiency is difficult to differentiate clinically from protein deficiency, which is of much greater concern. Also, please make sure that the meat and dairy that you consume is grass-fed/pastured and that vegetables and fruits are organic or locally grown using organic standards.
It is interesting that only two of the 20 amino acids normally present in foods contain sulfur: Methionine (must be supplied by diet) and Cysteine (requires dietary sulfur for the body to synthesize). Neither of these are stored in your body. Rather, “any dietary excess is readily oxidized to sulphate, excreted in the urine (or reabsorbed depending on dietary levels) or stored in the form of glutathione (GSH),” according to the researchers. (Glutathione is comprised of three amino acids: cysteine, glutamate, and glycine, and is your body’s most potent antioxidant, which also keeps all other antioxidants performing at peak levels.)
Radiation Protection and Sulfur
Human health can be adversely affected by exposure to radiation. This can come in the form of simple sunlight, to x-Ray exposure, to radiation fall-out. Tissue damage, whether resulting in a sunburn or in thyroid cancer is caused by “ionizing” radiation. Raising glutathione levels protects cells from damage by the most dangerous of free radicals released when ionizing radiation hits us. Jimmy Gutman, MD
Organic Sulfur acts in a powerful way to protect from radiation. Sulfur reacts with radioactive mineral isotopes, turning them into harmless sulfates. This reaction occurs naturally because of the electrons that are available in sulfur’s atomic structure. After the atomic bombs were dropped on Hiroshima and Nagasaki, many of the Japanese people survived radiation poisoning simply by eating their traditional miso soup, which is made from fermented soybeans, sea vegetables like kombu, and root vegetables—all of which are rich in iodine and sulfur. Dr. Gabriela Segura also states: “Sulfur has a long history of use as an antidote for acute exposure to radioactive material.”
