Eating In Tune With Our Body Internal Clock Helps To Prevent Cancer

Researchers have all heard of the link between eating sh*tty foods and cancer. The study investigated whether or not regularly eating dinner before 9 pm, or at least two hours before going to bed, could significantly lower someone’s risk of developing cancer. To find this out, researchers explored the nightly habits of a group of 1,826 breast and prostate cancer patients and compared them to 2,193 healthy individuals.

Disruptions In Circadian Rhythm

Researchers think it could be to do with disruptions to the circadian rhythm. The results indicated that those who recalled regularly eating dinner before 9 pm or at least two hours before going to bed had a 26% lower risk of developing prostate cancer and a 16% lower risk of developing breast cancer.

Needless to say, meal timing had a significant effect on the cancer risk factor of those participating. The study was published in the International Journal of Cancer.

Circadian Clock Protein BMAL1 Regulates IL-1? in Macrophages via NRF2

Researchers have revealed insights into how the body clock controls the inflammatory response, which may open up new therapeutic options to treat excess inflammation in conditions such as asthma, arthritis and cardiovascular disease. By understanding how the body clock controls the inflammatory response, they may be able to target these conditions at certain times of the day to have the most benefit.

These findings may also shed light on why individuals who experience body clock disruption such as shift workers are more susceptible to these inflammatory conditions. The study was published in the Proceedings of the National Academy of Sciences (PNAS), a leading international multidisciplinary scientific journal.

Association Between Circadian Rhythms And Mood Disorders

Circadian rhythms are regular 24-hour variations in behavior and activity that control many aspects of our lives, from hormone levels to sleeping and eating habits. Circadian rhythms are fundamental to health and are particularly important for mental wellbeing. Disrupted rhythms of rest and activity are recognized as risk factors for major depressive disorder and bipolar disorder.

The study was published in EBioMedicine, follow research published earlier this year in The Lancet Psychiatry which found that disrupted circadian rhythms were associated with increased risk of mood disorders, including major depression and bipolar disorder.

Association Between Morning-Eveningn Preference With BMI

People with prediabetes who go to bed later, eat meals later and are more active and alert later in the day those who have an "evening preference" have higher body mass indices compared with people with prediabetes who do things earlier in the day, or exhibit morning preference. The higher BMI among people with evening preference is related to their lack of sufficient sleep. The study was published in the journal Frontiers in Endocrinology.

Circadian Rhythm Could Help To Lose Weight, Sleep Better And Live Longer

A study examined that a lifestyle change based around our circadian rhythms to improve our health, beginning with when to eat, when to sleep, and when to get some exercise. LOSE weight, become more energetic and sleep well every night. Bold promises outlined on the cover of The Circadian Code. 

The term circadian is derived from the Latin ‘circa diem’, meaning ‘approximately a day’. This isn’t a diet, it’s a lifestyle change and one that involves relatively small adjustments to daily routines. It begins with knowing when to eat (as opposed to what) and when to turn off the lights, exercise, maximize sleep and brain function. 

Feeling Lonely Is Bad For The Heart

According to a study, researchers found that feeling lonely was a stronger predictor of poor outcomes than living alone, in both men and women. Loneliness is bad for the heart and a strong predictor of premature death. The study was published in the journal Cardiology.

Ineffectiveness of 'Growth Mindset' Educational Interventions

A new study co-authored by researchers at Michigan State University and Case Western Reserve University found that "growth mindset interventions," or programs that teach students they can improve their intelligence with effort—and therefore improve grades and test scores—don't work for students in most circumstances.
