Which type of vitamins must be consumed daily and are easily lost in cooking?

Water-soluble vitamins are those that must be consumed daily because they are not stored in the body. This includes vitamins like vitamin C and the B vitamins, which play crucial roles in various bodily functions such as energy production, immune function, and cell metabolism. These vitamins are easily lost in cooking processes, especially when they are exposed to heat, light, and water. For instance, boiling vegetables can result in significant losses of vitamin C and B vitamins, as they leach into the cooking water. Therefore, consuming a varied diet that includes these vitamins regularly is important to maintain adequate levels in the body, as any surplus is excreted through urine rather than stored.
