The WHO estimates that by 2050, 30% of the world's population will be elderly. The increased life expectancy of the population coupled with falling fertility contributes to this scenario in many countries. Although the life expectancy of the population has increased, the recurring concern is to ensure the quality of life of this group. Some diseases are directly associated with the aging process, such as sarcopenia and osteoporosis. On the other hand, chronic degenerative diseases, such as diabetes, hypertension, and cancer, are associated with long-term inadequate health habits and, therefore, are more prevalent in the elderly. Among the factors that contribute to a lifestyle that influences the onset of these diseases, we can highlight sedentarism and poor diet quality.

The relationship between nutrition and the quality of life of the elderly population and healthy aging will be covered in this research topic. Furthermore, we aim to bring together articles regarding the mechanisms leading to nutrition-related metabolic diseases, nutritional status in the elderly and their health impairment, nutritional influence in the therapy and recovery from diseases in old age.

We welcome studies (reviews, original research, metanalyses) on, but not limited to, the following topics:
- Nutritional risk, nutritional deficiencies and quality of life in the elderly.
- Alterations of the circadian regulation of the elderly system upon following diets/eating patterns.
- Postprandial effects of diets/eating patterns on the immune system regulation.
- The effect of diets/eating patterns on the immune system in the context of metabolic diseases.
- The effect of diets/eating patterns on cancer.
- The effect of diets/eating patterns on cardiovascular diseases, diabetes, and hypertension.
- Diets/eating patterns and modulation of immune-gut microbiota interplay.
- Sarcopenia (mechanisms and therapy).
- Osteoporosis (mechanisms and therapy).
- Neurodegenerative diseases and dementia.

Keywords: Diet, immune system regulation, microbiota, metabolic diseases, cancer, sarcopenia, osteoporosis
