Overeating can lead to dementia. Don't be obese at the age of 30.

With a busy work schedule, you often have a simple sandwich or rice balls for lunch, and then after get off work in the evening, you can have a big hotpot or eat all you can. Do you think you have a good meal? Be careful about long-term overeating, which can damage gastrointestinal digestion and increase the risk of obesity and dementia. Studies have found that the brains of middle-aged obese people age faster, and if weight is out of control at the age of 30, the chance of dementia is the highest in your lifetime.

Office workers often overeat, which can easily lead to obesity, which in turn increases the risk of cardiovascular disease and dementia.

Oxford University study: Obesity at age 30 is associated with the highest risk of dementia in the future

It is a recognized fact in the medical community that obesity can trigger metabolic syndrome, which can easily cause blockage of blood vessels in the brain and even hypoxia and necrosis, accelerate the degeneration of memory and brain function, and thereby increase the risk of dementia. The University of Oxford in the UK further analyzed more than 450,000 obese patients and found that among all age groups, the risk of dementia for those who are obese between the ages of 30 and 39 is the highest in their lifetime.

The results show that after the age of 40, the older you become when you gain weight, the lower your additional risk of dementia in the future. For people who are diagnosed as obese at the age of 40, the excess risk of dementia in the future drops to 70%; the excess risk of dementia for those who become obese at the age of 50 drops to 50%, and drops to 40% at the age of 60; the risk of dementia for those who become obese at the age of 70 is similar to that of the average person.

The more you gain weight in middle age, the greater your risk of dementia

Regarding the above study that mentioned that people who become obese at the age of 30 have the highest risk of dementia in their lifetime, although it is only the result of relative statistical data and its authenticity still needs to be verified by more research, Dr. Liu Yiqian from the Department of Neurology of Catholic Gengshen Hospital said that obesity is one of the known risk factors for the onset of dementia. If we look at it from the perspective that the younger you become obese, the longer and greater the impact of inflammatory substances on your cardiovascular and cerebrovascular systems, it is reasonable to infer that people who are obese at a young age may have a higher risk of dementia in the future.

Studies have found that the higher the degree of obesity among people who become obese in middle age, the higher the risk of developing dementia in the future.

What is more certain than the age of obesity is that obesity increases the risk of dementia. Dr. Liu Yiqian pointed out that more and more studies abroad have found that obese people with a BMI ≥ 30 after middle age have a three-fold increased risk of developing dementia in the future than the average person, while the risk for overweight people (25 ≦ BMI ＜30) is doubled.

Are obesity rates low among dementia patients? Doctor: Illness reduces nutrient absorption

However, what is special is that the obesity rate among dementia patients is not high. Dr. Liu Yiqian said that dementia is a chronic disease like cancer. Patients are prone to poor chewing ability and nutrient absorption, and their bodies will naturally become thin. The more severe the dementia, the faster the weight loss. In addition, compared with sarcopenia caused by normal aging, the muscle loss and weight loss of people with dementia are more obvious because their bodies cannot maintain normal functions due to illness.

If you want to avoid the threat of dementia, eliminating obesity is a necessary measure. As for diet, you should develop the habit of eating five kinds of fruits and vegetables every day, increase fiber intake and satiety, drink less sugary drinks, eat three meals on time and in a balanced diet, eat until you are 80% full at each meal, and eat less midnight snacks and desserts. As for exercise, it is recommended to maintain more than 150 minutes of physical activity per week, move more and sweat more, improve physical condition, and reduce the accumulation of excess fat in the body.
