The present invention discloses an anti-radiation nougat which consists of the following materials: fructo-oligosaccharide, lactitol, apricot kernels, rice protein foam powder, soy lecithin, anhydrous butter, skim milk powder, modified potato starch, iodized edible salt, collagen elastic material, rutin, lycopene, and selenium yeast. The provided anti-radiation nougat is rich in nutrition, mellow in taste, and moderate in sweetness, and does not stick on teeth. The fructo-oligosaccharide and lactitol replace white granulated sugar to enable a sweet taste sensation of the nougat, which is also conducive to the growth of bifidobacteria, prevents obesity, tooth decay, constipation and high blood pressure, and is suitable for a wide population. Modified potato starch is used to replace gelatin to enable the nougat to be safety and health, and to have a significantly increased crisp feeling. Iodine, collagen elastic material, rutin, lycopene and selenium-rich yeast are added in the nougat, thus the nougat is rich in nutrition and can repair the symptoms caused by radiation and prevent cancer. The varieties and functions of nougat are increased, and the shortcomings of relatively simple nougat in the market are made up.
