After the 100th cycle, the cell with 80 wt% sulfur content can retain 819 mA h g −1 under 0.2 C. Also, when the electrolyte/sulfur ratio is reduced to 15 µL mg −1 and 5 µL mg −1, respectively, considerable capacity retention of 736.3 mA h g −1 and 615 mA h g −1 is achieved after the 100th

The ability to reduce sulfur in fuels is an important step toward reducing emissions. However, extremely low levels can be difficult to achieve. Now, Caltech researchers have demonstrated an unorthodox approach that lowers sulfur content in diesel to about 2 ppm.

Good choices include: 3-4oz portions of animal protein or protein from beans/lentils/legumes with low-sulfur veggies, such as salads, carrots, celery, mushrooms, bell peppers, cucumbers, eggplant, spinach, collards, artichokes, and corn. All sorts of squash are great, including acorn, spaghetti, crookneck, zucchini, pumpkin and yellow squash.

The sulfur content of United States coal can be assessed using a variety of approaches. The sulfur content may be expressed in terms of total sulfur in the coal, pounds of sulfur per million Btu, or sulfur remaining after reduction by coal preparation. In addition, sulfur content may be applied to the demonstrated reserve base or to coal resource estimates.

I think it's easier to avoid the very high-containing sulfur foods and go from there with your meals. Any cruciferous vegetables will be high in sulfur such as cauliflower, brussels sprouts, broccoli, cabbage, …
