Insights

Exclusive breastfeeding for at least four months may protect against psoriasis development. Early infant formula and high milk consumption were linked to increased psoriasis risk in a large birth cohort study.

Area of Science:

  • Dermatology
  • Pediatrics
  • Nutritional Science

Background:

  • Psoriasis is a genetically influenced systemic skin disease.
  • Environmental factors trigger psoriasis manifestation.
  • Early nutrition is a potential, understudied trigger.

Purpose of the Study:

  • To investigate the association between early nutrition and psoriasis risk.
  • To identify specific dietary factors influencing psoriasis development in childhood.

Main Methods:

  • Analysis of the All Babies in Southeast Sweden (ABIS) prospective birth cohort (n=16,415).
  • Data collected via parental questionnaires at birth, 1, and 3 years.
  • Psoriasis diagnosis confirmed using national patient and drug registers.

Main Results:

  • Breastfeeding < 4 months and infant formula before 4 months increased psoriasis risk (OR 1.84-1.88).
  • High milk consumption correlated with higher psoriasis risk (OR 2.53).
  • Increased fish consumption, particularly from the Baltic Sea, significantly raised psoriasis risk (OR 9.61).

Conclusions:

  • Early nutrition significantly impacts psoriasis manifestation.
  • Exclusive breastfeeding for 4 months shows a protective effect against psoriasis.
  • Dietary patterns in infancy may play a crucial role in psoriasis etiology.

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
Weaning, typically occurring...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
