The present invention provides a functional food that utilizes health-promoting effects of charcoal, is readily ingested, has no adverse side effect, and has an effect of improving and repressing obesity. The functional food includes a charcoal composition having at least one of a bamboo charcoal, a Bincho charcoal, an activated bamboo charcoal and an activated Bincho charcoal, and both of the activated bamboo charcoal and the activated Bincho charcoal have a bulk density of 0.3 to 0.6 g/ml, an average particle size of 10 m or smaller, a BET specific surface area of 1000 to 1200 m.sup.2/g, and an iodine adsorption amount of 1000 to 1300 mg/g.

The present invention relates to a process for preparing an additive as a food supplement based on algae for birds and animals. It also describes the food additive obtained, formulated with seaweed extract, whey, malto-dextrin, proteins, amino acids, minerals, fiber, fat, hormones, and has a final powder form. In addition, the use of the food additive to increase the weight gain in animals, the weight gain in eggs of birds, and for the production of meat in birds and animals is described.
