The wakame (Undaria pinnatifida) is an edible algae which, with kelp (Laminaria japonica) represents a food resource of primary importance for the global economy, particularly for the countries of East and Southeast Asia. Among the different species of brown algae used for direct and indirect food purposes, wakame represents the richest source of protein. It has an average content of 16.3 grams per hectogram of product.
The amino acid profile and protein quality indices are also good: wakame contains all the essential amino acids. Wakamé algae contains iodine and selenium, two minerals very important for the balance of the thyroid gland and for maintaining metabolism. The vitamins and mineral complex contained in wakame seaweed are a panacea even for people suffering from nutritional deficiencies.
Wasabi is a plant of Japanese origin belonging to the same botanical family as radish, horseradish, arugula and cabbage. The roots of this prized and very ancient plant are difficult to find and expensive, because they grow quite slowly. From the root of this plant, we obtain a green paste with a particularly spicy taste and a fairly dense consistency, well known to those who have tasted Japanese cuisine at least once. It is, in fact, generally used as an accompaniment to typical dishes of the oriental tradition, such as sushi, sashimi, tempura. This vegetable can boast of antiseptic and antioxidant properties, as well as a high concentration of vitamin C. In addition, this root can be considered a natural antimicrobial agent.
Ximenia is the fruit of Ximenia americana. The ripe pulp of this fruit native to West Africa contains 65% water, 6% proteins, 23% lipids and 11% soluble sugar.

The fruit is particularly appreciated in rural areas during the period of food scarcity, which corresponds to the fruiting period of the species. The oil extracted from the seeds of X. americana is used locally for food, medicine and cosmetics.
Yacon is a vegetable native to the Andes mountain range, between Argentina and Colombia. It is the root of Smallanthus sonchifolius. It is also known as jiquimilla.

The more the root matures, the milder its flavor will be. Composed almost entirely of water and oligosaccharides (typically fructose), it is a low-calorie food but which has the same properties as prebiotics. The amount of fiber and protein it contains is ideal for the intestine. But it also has beneficial effects on the immune system and cholesterol, given its anti-inflammatory action.
