"Tomatoes are longevity fruits, how can I get diabetes if I eat them!"
Three months ago, 48-year-old Ms. Chen swiped a video about tomatoes on the Internet, in which it was not only said that tomatoes can whiten and anti-aging, but also protect cardiovascular and prevent cancer, and are also known as "longevity fruits".
So, in line with the idea of eating more beneficial, Ms. Chen began to eat tomatoes from time to time throughout the day, and she persisted for 3 months, but before she could see any changes in her skin, the illness found her.
In the past few days, Ms. Chen has found that she is often dizzy, and her body is tired and weak, and she can't do anything. After coming to the hospital for examination, Ms. Chen couldn't believe the results: fasting blood sugar was 7.2mmol/L, and she was preliminarily diagnosed with diabetes.
After in-depth communication with the doctor, Ms. Chen learned that eating too many tomatoes may have helped her on the way to diagnosing diabetes, which made Ms. Chen accept incompetence, didn't it mean that it was beneficial?
The doctor said: "Tomatoes can be eaten in moderation, but if you eat them in large quantities for a long time, these two disadvantages are likely to come to your door." ”
Tomatoes that are full of treasures, and eating a lot of them for a long time will have 2 disadvantages
It's interesting to have the question: "Are tomatoes a vegetable or a fruit?"
According to the definition of fruit in Merriam-Webster's Dictionary: edible propagules of seed plants, tomatoes belong to fruits, but in daily life, the public generally treats tomatoes as vegetables.
In fact, tomatoes are a typical dual-purpose fruit and vegetable, which can be used as a fruit when eaten raw and as a vegetable when cooked. Tomatoes are rich in organic acids, vitamin C, and lycopene, which are also the source of tomatoes' good reputation.
Organic acids and other acids help the body secrete digestive juices to help improve digestion, vitamin C is beneficial to promote the formation of collagen in the body, which can make the skin elastic and help with antioxidants, and lycopene has the effect of scavenging free radicals, which helps prevent cancer, protect cardiovascular health and delay aging.
However, there are two sides to everything, and while tomatoes bring benefits, eating them in large quantities over a long period of time can also cause trouble.
1. If your blood sugar is unstable, you often eat tomatoes, and be careful that diabetes comes to your door
Ms. Chen was originally unstable in blood sugar and did not take medication, and heard that the sugar content of tomatoes is not high, only 2%-4%, so she ate it unscrupulously.
Although the sugar content of tomatoes is indeed not high, it is not allowed to be overeaten, and the sugar in tomatoes will accumulate and interfere with the body's already unstable blood sugar, resulting in high blood sugar and increasing the risk of diabetes.
This is mainly because the mechanism of diabetes is inseparable from insulin resistance, when the blood sugar in the body is unstable, the patient will be in a pulsatile secretion mode of insulin secretion, regulating insulin levels. At this time, if a large amount of sugar is ingested, insulin resistance will be too long, the quality of insulin secretion will deteriorate, and the quantity will be reduced, resulting in the inability to meet the body's need for hypoglycemia, and it is easy to evolve into diabetes for a long time.
However, diabetics are not necessarily caused by eating tomatoes regularly, after all, the etiology of diabetes is complex, there are genetic factors, such as the presence of diabetes genetic susceptibility genes in the body, environmental factors, such as viral infections, and pancreatic islet cell damage caused by immune system defects, which can lead to diabetes.
Also, sleep deprivation can increase the risk of diabetes!
JAMA Network Open has published a study on "Lack of Sleep, Increases the Risk of Diabetes", the research team retrieved genetic sequencing data from the British Biobank, randomly selected 247867 subjects, and grouped them according to different sleep times every day.
People who slept 5 hours a day and 3-4 hours a day had a significantly increased risk of developing type 2 diabetes, with a risk of 1.16% and 1.41%, respectively, compared to the normal rate of 0.75% diabetes.
It can be seen that sleep does affect the risk of diabetes.
However, due to the complexity of the etiology of diabetes, the methodology of this study has certain limitations, and it cannot conclusively prove the inevitable link between sleep deprivation and increased risk of diabetes, which needs to be further studied.
2. Eat tomatoes on an empty stomach with a bad stomach, and be careful of stomach damage
In addition to raising blood sugar and increasing the risk of diabetes, tomatoes also have a relatively hidden disadvantage - hurting the stomach!
As a fruit and vegetable food that can be eaten raw, tomatoes contain a large amount of pectin, which is an insoluble substance, when we eat on an empty stomach, due to the highest concentration of gastric acid in the stomach, when the gastric acid is combined with pectin substances, there will be a chemical reaction, and the insoluble lumps will accumulate in the stomach, and excessive amounts will increase the pressure on the stomach, and gastric dilation or gastric acid may occur.
However, the effects of eating tomatoes on an empty stomach need to be determined according to the health of the stomach.
If you have a healthy stomach, eating tomatoes on an empty stomach will not cause gastrointestinal harm and discomfort. Patients with stomach diseases such as weak gastrointestinal function, gastritis, gastric ulcer, etc., when eating tomatoes on an empty stomach, the components in tomatoes enter the stomach and intestines through the digestive system, and the citric acid and malic acid in the fruit acid will combine with gastric acid to stimulate the gastric mucosa, resulting in gastrointestinal dysfunction and gastrointestinal discomfort, and the possibility of aggravating the pre-existing disease cannot be ruled out.
Therefore, people with poor stomach should try to eat tomatoes after meals to reduce the irritation of the gastrointestinal tract, and the amount of intake should also be controlled, and one a day has the best effect.
Is it true that eating tomatoes may help reduce the risk of high blood pressure?
Eating tomatoes is good for the body, and this pack does not include the help to reduce the risk of high blood pressure?
Tomatoes may help lower blood pressure, perhaps because tomatoes are rich in lycopene, which has a powerful free radical scavenging effect, and even vitamin E, which is known as a free radical killer, is not its opponent.
When the free radicals that destroy cells in the body are reduced, the immunity will be improved, which can deeply clean the garbage of blood vessels and organs, help regulate plasma cholesterol concentration, and prevent cardiovascular and cerebrovascular diseases and high blood pressure.
In addition, tomatoes can help lower blood pressure may also be related to the potassium contained in them, which helps to move water from outside the cells into the cells, resulting in a decrease in blood volume, which in turn plays a certain role in lowering blood pressure.
The relevant study has appeared in 2022, and the research team of Sun Yat-sen University conducted a trial on the link between tomato intake and hypertension, and conducted a group follow-up survey on tomato intake among 11,460 non-hypertension research subjects, and learned that:
As tomato intake increases, so does the risk of new-onset hypertension. Tomato intake 0-13.3 g per day reduced the risk of new-onset hypertension by 58%, 13.3-33.3 g per day reduced the risk by 49%, and tomato intake over 33.3 g per day reduced the risk of new-onset hypertension by 18%.
Graph analysis showed that there was a J-shaped relationship between tomato intake and new-onset hypertension, showing a negative correlation. This tells us that although tomatoes have the effect of reducing the risk of high blood pressure, it is not that the more you eat, the better, and if you eat too much, it will reduce the protective effect.
However, it is important to note that tomatoes only prevent the risk of high blood pressure, not cure the disease, and if you already have high blood pressure, you should seek medical attention as soon as possible for medical intervention.
In general, tomatoes should not be eaten in large quantities for a long time, and Ms. Chen's diabetes after eating for three months is a warning, and when eating tomatoes, do not overdo it, and control it at about 100g to better meet the needs of the human body.
