Is disease really related to eating?

In this article, we present recent advances in research on the association between food and disease occurrence.

[1] Popeye: Eating spinach really makes your muscles stronger!

Do you remember the protagonist in a cartoon that I saw as a child, Popeye Bobby? At every critical juncture, as long as you eat spinach, Bobby can become a big force, and the big bad guy Bruto can escape.

Recent studies have found that spinach can really make you stronger, but this effect is not caused by the iron in spinach, the high concentration of nitrate in the green leaves is the real reason.

Numerous studies have shown that nitrate in the diet can strengthen the muscles of elite athletes. Researchers from the University of Washington School of Medicine have found that drinking concentrated beet juice containing high levels of nitrate can increase the muscle strength of patients with heart failure. The researchers said that although this was a small study, we observed very significant changes in muscle strength two hours after the patient had been drinking beet juice.

In this study, the researchers studied nine patients with heart failure. They used their own control to drink beet juice and beet juice with only nitrate removed. The interval between treatments was one to two weeks. Ensuring that the previous treatment does not affect the latter, and the participants and the investigator are not aware of the treatment sequence.

[2] STM: Why does eating too much cause diabetes?

Everyone knows that a high-calorie diet is directly related to obesity and, of course, to the onset of type 2 diabetes; a research report published today in the international journal Science Translational Medicine, researchers from Temple University said that they are gorging Diet may also allow the body to quickly enter pre-diabetes symptoms.

In the article, the researchers studied six healthy men who were overweight or overweight. The researchers asked these participants to consume 6,000 calories per day for a typical American diet. This way, the food intake increased dramatically. According to the American Medical Association, a healthy diet should be an average of 2,200 calories per day for men who are between 30 and 50 years old.

These participants were closely monitored in the hospital and they also underwent a high-calorie diet during which they were not allowed to participate in any form of physical activity. Researcher Dr. Guenther Boden said that all individuals gained an average of 8 pounds over the course of a week. In addition, within two days after starting this diet, all male individuals reached a common name called insulin resistance. The metabolic state, which is usually considered to be a precursor to diabetes, occurs when the body is able to produce hormones but cannot be used effectively.

[3] JNB: colored potatoes help fight cancer

Recently, scientists from the Hershey Cancer Institute in Pennsylvania, USA, found that some compounds in purple potatoes may help kill colon cancer stem cells and limit cancer development. The relevant research results are published in the International Journal of Journal of Nutritional Biochemistry.

According to the American Cancer Society, colon cancer is the second leading cause of cancer deaths in the United States, with more than 50,000 patients dying from colon cancer each year. Attacking cancer stem cells is an effective way to fight cancer. Cancer stem cells are like grass roots. As long as cancer stem cells are still there, tumors will continue to grow and spread.

Potatoes are a widely used crop, especially in some Western countries, baked potatoes are foods that people eat regularly.

In this study, the researchers found that extracts from baked potatoes inhibited colon cancer stem cell growth and promoted death. They then examined the effects of feeding roasted purple potatoes on a colon cancer mouse model and found similar results.

Researchers believe that purple potatoes may contain substances that act on multiple signaling pathways to help kill colon cancer stem cells, including anthocyanins, chlorogenic acids, and resistant starches.

[4] JCO: Drinking coffee every day reduces the risk of colon cancer recurrence

Coffee is a caffeine-containing beverage made from roasted coffee beans. It is the main drink popular in the world with cola and tea. And whether coffee has always affected health is a topic that many people are extremely concerned about. Scientists have been arguing over the years.

Recently, scientists from the Dana Farber Cancer Center in the United States conducted a study that found that daily consumption of caffeinated coffee can help prevent colon cancer recurrence after treatment and increase the chance of colon cancer cure. The relevant research results were published in the International Academic Journal Journal of clinical oncology.

The study included nearly 1,000 colon cancer patients who were surveyed during the early stages of the study and one year later, and their coffee drinking habits were counted. The results showed that among patients with stage III colon cancer who underwent surgery and chemotherapy, patients who drank more than 4 cups of coffee per day (about 460 mg of caffeine) benefited the most. These patients had cancer recurrence compared with patients who did not drink coffee. The risk was reduced by 42%, and the risk of death from cancer or other factors was also reduced by 33%. Drinking 2 to 3 cups of coffee a day is more beneficial, and people who drink only 1 cup or not every day will not benefit.

[5] BMJ: Does eating spicy actually help health?

A new study published this week in the British Medical Journal shows that spicy foods can be used as part of a daily diet to reduce the risk of death. This is an observational study, so there is no clear conclusion between causality, but the authors call for more research on “updated dietary recommendations and functional food development.”

Previous studies have shown that the beneficial effects of spices and their bioactive ingredients such as capsaicin include anti-obesity, anti-oxidant, anti-inflammatory and anti-cancer properties.

So an international team led by researchers at the Chinese Academy of Medical Sciences examined the relationship between eating spicy food as part of the daily diet and the cause of the total risk of death.

They conducted a prospective study involving a total of 487,375 participants between the ages of 30 and 79. Selected participants were followed up for their morbidity and mortality between 2004 and 2008.

All participants completed a questionnaire on health, including physical examination, eating spicy food, red meat, vegetables and alcohol.

[6] fat weapon to lose weight: grape seed oil!

In a recent research paper published in the international magazine Food and Function, researchers from the University of Florida have shown that petal seed oil can be used as a form of vitamin E to provide scientists with a weight loss. New means. This grape seed oil can help slow down the formation of fat cells in the body, which can produce a tocotrienic acid, which is an unsaturated form of vitamin E.

Researcher Marshall said that ingesting food made from muscadine seed oil can reduce body weight by reducing obesity; while muscadine seed oil may also be a valuable edible supplement on the market because it is The only source of tocotrienic acid, and it is also a good source of polyunsaturated fatty acids and monounsaturated fatty acids, the researchers also hope to use the grape seed oil as a basis to develop new strategies to help fight obesity.

Before the study, the researchers attributed the benefits of most tocotrienols to red palm and rice bran oil. In fact, recent studies have shown that rice bran oil can help lower cholesterol; as the research progresses, the grape seed oil also It is considered to be the main source of tocotrienol, and in this study, researchers first explained how to help growers produce large quantities of grape seed oil.

Round-leaf grapes, which are thick and have large seed granules, are mainly grown in the southern United States and are commonly used in the manufacture of alcoholic and fruit juices; each year, after the production of alcohol and juice, thousands of tons of pomace by-products are produced, traditionally In terms of angle, most of the pomace by-products will be disposed of as garbage, but some wineries will use the oil from the grape seed, and some will store these by-products.

[7] IJO: The scientific basis for eating fruit to lose weight

Recently, researchers from Washington State University found that berries, grapes, and other fruits can convert excess white fat into calories that burn calories, which provides a new strategy for the prevention and treatment of obesity.

In the study, the researchers fed mice with a high-fat diet and divided the mice into two groups, one of which was treated with resveratrol at a dose equivalent to 12 ounces of fruit per day. After the time, the weight gain of the high fat diet mice treated with resveratrol was 40% less than that of the control mice.

Previous studies have found that resveratrol can help prevent obesity, but the mechanism is not clear. And most of the research is focused on wine, and the concentration of resveratrol used is not available in normal diets. In the study, the researchers demonstrated that 0.1% resveratrol in the diet of mice can convert excess white fat into a beige fat with energy-consuming activity. The researchers explained that polyphenols in fruits, including resveratrol, can increase the expression of genes involved in the fat oxidation process, thus ensuring that the body does not overload. These polyphenols can promote the conversion of white adipose tissue to Burning fat to produce heat-producing beige fat helps the body maintain energy balance, thereby preventing obesity and metabolic disorders.

[8]Heart: Eat some chocolate, stay away from heart disease!

Recently, in a research paper published in the international magazine Heart, researchers from abroad have shown that daily intake of 100g of chocolate is directly related to the risk of heart disease and stroke; however, there seems to be no evidence of reduced chocolate intake. Will reduce the risk of cardiovascular disease in individuals.

The study was based on the researchers’ tracking of 21,000 adult individuals, and the researchers also analyzed the previous literature on the association between chocolate and cardiovascular disease. The researchers were participants (9214). Men and 11737 women were followed up for an average of 12 years, and 3,013 individuals experienced fatal or non-fatal heart attacks and strokes during the study period.

Twenty percent of the subjects said they did not consume any chocolate, but other individuals consumed an average of 7g of chocolate per day, and some individuals even ate 100g of chocolate; high levels of chocolate intake and individual age and BMI The index is directly related, and excessive intake of chocolate is often associated with high energy intake and a high-fat, low-protein diet. The researchers said that individuals with higher levels of chocolate had a 11% lower risk of cardiovascular disease and a 25% lower risk of cardiovascular disease-related deaths compared to individuals who did not.

[9] Eat more peanuts and nuts, reduce the risk of multiple diseases

Recently, a study published in the international journal of epidemiology confirmed that there is a correlation between peanut and nut intake and low mortality, but peanut butter has no similar protective effect. People who consume at least 10 grams of nuts or peanuts a day are less likely to die from several major risky diseases than those who do not eat peanuts and nuts.

The study pointed out that the most significant decline in mortality was respiratory disease, neurodegenerative diseases and diabetes, followed by cancer and cardiovascular disease, and the protective effect of peanuts and nuts was equivalent between males and females. At the same time, peanuts have the same protective effect as nuts, but peanut butter is not significantly associated with mortality.

The study began in 1986 when researchers conducted a cohort study of 120,000 Dutch residents aged 55-69, both male and female. In the study, the researchers asked the subjects about peanuts, nuts and Peanut and nut intake was assessed for issues such as the amount and frequency of peanut butter intake. They then analyzed the overall mortality and mortality rates for specific diseases after 1986.
