The nutritional and epidemiological transitions have changed the way of life for Algerians. It is observed in their nutritional status, eating behavior, and health status. Overweight and obesity are present at all ages of life. This complex problem includes many factors related to the risk of developing, at an older age, non-communicable diseases such as diabetes and cardiovascular disease. The nutritional situation of children under 5 years remains a concern of low birth weight, low prevalence of exclusive breastfeeding, stunting growth, and underweight. Nutritional deficiencies, mainly in micronutrients, persist in different age groups especially in pregnant and lactating women reflecting the consequences of a poor diet characterized by low consumption of fruits and vegetables, and higher consumption of fatty products as well as sweet having high energy density. The issue of food and nutritional security remains an important issue. Despite the persistent nutritional problems, the level of food security indicators show that the country is not exposed to food insecurity, but dependency on food imports remains quite high.
