Diet & Nutrition

Food and beverages provide the energy and nutrients you need to improve health, manage disease, and reduce the risk of disease. Complete nutrition requires ingestion and absorption of vitamins, minerals, essential amino acids from protein and essential fatty acids from fat-containing food, also food energy in the form of carbohydrate, protein, and fat. Dietary habits and choices play a significant role in the quality of life, health and longevity.

Traditional Inuit Diet: Foods, Nutrition, and Health Effects

Traditional Inuit diets combine nutrient-dense marine and terrestrial country foods that remain important sources of protein, vitamin D, vitamin B12, iron, and other essential nutrients. The transition toward market foods is occurring alongside changes in cardiometabolic health, micronutrient intake, and gut microbiome patterns, while food insecurity, socioeconomic conditions, physical activity, colonial processes, and environmental change complicate the relationship between diet and health.

Rice, fish and pickles: Is the traditional Japanese diet as healthy as we think?

A systematic review of 37 studies found that greater adherence to predefined Japanese-style dietary patterns was associated with lower all-cause and cardiovascular mortality, based on pooled evidence from three cohort studies. However, health associations varied according to dietary composition, suggesting that traditional Japanese diet scores alone may not adequately distinguish the potential benefits and risks of different food combinations.

Researchers found that a previously validated 67-metabolite blood signature of Mediterranean diet adherence was associated with lower long-term mortality across a Spanish trial population and three US cohorts. Participants with the highest signature scores had a 23% lower relative hazard of death than those with the lowest scores in both populations, although the findings do not establish a causal relationship.
