I know at the very start of my diet last year I had made up a milkshake and someone called and by the time I had it 30 minutes or so later and I know it did upset my tummy and I have never done that again.
Vitamins are essential nutrients found in foods. The requirements are small but they perform specific and vital functions essential for maintaining health.
The two types of vitamins are classified by the materials in which they will dissolve. Fat-soluble vitamins -- vitamins A, D, E and K -- dissolve in fat before they are absorbed in the blood stream to carry out their functions. Excesses of these vitamins are stored in the liver. Because they are stored, they are not needed every day in the diet.
By contrast, water-soluble vitamins dissolve in water and are not stored; they are eliminated in urine. We need a continuous supply of them in our diets. The water-soluble vitamins are the B-complex group and vitamin C.
Water-soluble vitamins are easily destroyed or washed out during food storage or preparation. Proper storage and preparation of food can minimize vitamin loss.
