Total saturated fatty acids concentration in diet correlates with serum HDL-C positively; increasing dietary fat and saturated fat not only increase LDL-C content, but also increase HDL-C content.

膳食中的总饱和脂肪酸含量与人体血清中hdl - C呈正相关，增加膳食中总脂和饱和脂肪的含量不仅会增加LDL - C含量，也会增加HDL - C的含量。

How long they can be used until they are saturated depends on the concentration of arsenic in the particular area that they are being used.
