Try nut butters. There are many more available other than peanut butter, try others such as hazel nut or cashew nut butter. Soya products are excellent and easily digested sources of protein. Choose the nutritional supplemented soya milks with added calcium and sugar. If you use dairy products , make good use of soft milky puddings, such as custard and rice pudding.
Vegans can also get a variety of soya pudding, including soya rice pudding.
If you like, add jam, honey, ground nuts or cream to your pudding. If you prefer to have white bread, white pasta and refined rice, then do so. But remember that the wholemeal varieties are very good sources of the B vitamins. Complement cereals with other sources of proteins, such as nuts, seeds , pulses , milk and cheese . Tahini is particularly good when combined with a mashed pulse, such as chick peas to make hummus.
