Cognitive health may benefit from a balanced meal schedule – Neuroscience News

Summary: Breakfast may very well be the most important meal of the day, especially in terms of maintaining good cognitive health. Researchers have found that skipping breakfast increases the risk of cognitive decline in middle-to-old-aged people, while maintaining a temporal distribution of energy intake over the course of a day helps maintain cognitive health.

Globally, approximately 55 million people suffer from dementia and the incidence of the disease has been steadily increasing. Population numbers are expected to triple by 2050, especially in low- and middle-income countries. Dementia not only affects the quality of life of individuals, but also adds a significant economic burden to families and society.

Epidemiological studies have shown a correlation between the temporal distribution of energy intake over the course of a day (TPEI) and the risk of various chronic diseases such as diabetes and hypertension. However, evidence regarding the relationship between TPEI and cognitive function at the population level is relatively lacking.

Previous studies in animal models have shown that mealtime disruption can lead to alterations in clock rhythms in the hippocampus, thereby affecting cognitive function.

According to a short-term intervention trial of 96 young adults, dividing equal amounts of food into four meals between 9 a.m. and 3 p.m. may improve cognitive function compared to eating twice between 9 a.m. and 3 p.m. However, long-term studies on TPEIs and cognitive function are lacking.

Recently, Drs. Changzheng Yuan and Dongmei Yu from Zhejiang University published an article in life metabolism titled “Temporal patterns of energy intake and cognitive function and its decline: a community cohort study in China”.

Based on the public China Nutrition Health Survey (CHNS) database, a total of 3,342 participants were included in this study, who were middle-aged and older adults (mean age 62 years) from nine provinces from China with a reference age ≥ 55 years.

The researchers used: 1) A data-driven k-means algorithm to identify six TPEI patterns, including the “evenly distributed” pattern, the “breakfast dominating” pattern, the “lunch dominating” pattern, the “dominating dinner” model, “rich in snacks” model and “breakfast skipping” model;

The result showed that, compared to those with an “equally distributed” pattern, long-term cognitive function scores were significantly lower in those with unbalanced TPEIs, especially those with a “breakfast skipping” pattern. “. Image is in public domain

2) Cognitive function was assessed using modified telephone interviewing for cognitive status (TICS-m), including immediate and delayed word recall (20 points), countdown (2 points) and a series 7 subtraction test (5 points). The total global cognitive score ranged from 0 to 27, with a higher score representing better cognitive function;

3) The correlation of TPEIs to cognitive functions over 10 years was evaluated using linear mixed models (LMM), adjusted for age, sex, residence, total energy, physical activity, smoking status, alcohol consumption, household income, level of education, and body mass index (BMI).

The result showed that, compared to those with an “equally distributed” pattern, long-term cognitive function scores were significantly lower in those with unbalanced TPEIs, especially those with a “breakfast skipping” pattern. “.

Thus, maintaining balanced TPEIs has potentially positive effects on cognitive health, while skipping breakfast may significantly increase the risk of cognitive decline in middle-aged and older adults. In conclusion, this study highlights the importance of optimal TPEIs in cognitive function.

Summary

Temporal patterns of energy intake and cognitive function and their decline: a community cohort study in China

Worldwide, around 55 million people had prevalent dementia in 2019, which is expected to triple by 2050, particularly in low- and middle-income countries. The lack of rapid diagnosis and limited effective treatment of dementia makes the identification of risk factors crucial for its early prevention, dietary factors are receiving increasing attention.
