Red Meat and Processed Meat Can Become a Cause of Diabetes

By | Diabetes, meat, Processed food, processed meat, red meat

A clinical study at the end of 2023 showed that red meat and processed meat can become a cause of diabetes. The authors published the results of this study in The American Journal of Clinical Nutrition on December 2023.

Results of the study

Notably, the study consisted of several pooled studies. To emphasize, there was a total of 216,695 participants and the authors followed them up every 2 to 4 years. In detail, the investigators analyzed food frequency questionnaires for consumption of red meat, processed meat, and consumption of nuts and legumes. In particular, the authors compared the highest and lowest red meat consumption quintiles. Those who ate the highest amounts of total red meat had a risk of 1.62-fold to develop diabetes. With regard to processed meat the risk was 1.51-fold to develop diabetes. And those who consumed unprocessed red meat had a risk of 1.40-fold to develop diabetes.

• When people replaced 1 serving of meat per day with nuts and legumes, this reduced their risk for diabetes by 30%.
• A group that had replaced processed red meat by 1 serving/day with nuts and legumes reduced the risk for diabetes by 41%.
• Replacing unprocessed red meat by 1 serving/day with nuts and legumes reduced the risk for diabetes by 29%.

Some scientists criticized the study saying that it was not controlled for elevated body mass index (BMI). A person with an elevated BMI is at a higher risk of developing diabetes on its own and this can interfere with a study like this.

Alternative large study confirming risk of red meat to develop diabetes

This study was a meta-analysis, which involved data from 31 cohorts participating in the InterConnect project. There was a total of 1,966,444 adults in this study and 107,271 patients developed diabetes over a period of 10 years.

• People who ate unprocessed meat had a 10% increase of diabetes risk compared to people not consuming meat.
• When processed meat was consumed it caused diabetes in 15% of the study group.
• On the other hand, poultry consumption caused only 8% of diabetes.

There were slight regional differences for the same foods. In the discussion of the data the authors pointed out that in comparison to the first study mentioned above their risk ratios were lower, because all the data was corrected for compounding factors that could distort the figures. As an example, they noted that without BMI adjustment unprocessed meat would have caused 18% of diabetes. On the other hand, processed meat would have caused 23% of diabetes and 21% of diabetes for poultry consumption.

Recommendation to reduce or eliminate red meat consumption

The American Institute for Cancer Research recommends to eat less than 18 oz. of red meat or processed meat per week to avoid cancer development.
You can replace meat with nuts, legumes (lentils and beans), tofu and vegetables.

Conclusion

Two independent large studies concluded that consumption of red meat and processed red meat contributed to diabetes development in adults. We also know from other studies that it can cause cancer. The key is to replace red and processed red meat by nuts, tofu, legumes and other vegetables. Both studies have shown that doing so reduces the risk for diabetes.

Poor Health is Linked to Loneliness and Social Isolation

By | Anxiety, Cancer, Cardiovascular disease, depression, heart attack, Heart Disease, Mortality

In June 2023 a new study showed that poor health has a link to loneliness and social isolation. It was also reviewed by CNN. There have been many studies in the past examining whether poor health shows an association to loneliness and social isolation. But this new study is different: it is a meta-analysis of 90 prospective studies with follow-up from 6 months to 25 years. The study included only persons age 18 years and older. There was a total of 2.2 million participants. The study specifically examined the links between loneliness, social isolation and early death.

The Meta-analysis

This new meta-analysis is significant, because with such a high number of participants the statistical strength is much better than with smaller studies. All of the 90 studies examined were prospective studies. The meta-analysis showed the difference between controls and various experimental groups suffering loneliness, social isolation and early death. The researchers identified independent risk factors of subsets among the 2.2 million subjects as discussed further below.

Loneliness

The definition of loneliness in the study was the subjective distress people feel when there is a discrepancy between the social relationships they have and what they want. If their is no fulfillment of the need for connection or intimacy in their relationships, this too can be a source of loneliness. There is increased isolation of Americans due to the increase in TV watching, spending more computer time and increase in cell phone use. This is loneliness by choice. But very few know that this can cause disease.

Social isolation

When people are under social isolation, they are under chronic stress, which translates into disease. In the statistics below it is apparent that cancer and cardiovascular mortality show a significant elevation from social isolation. In women with breast cancer there was a 51% increased mortality due to social isolation.

Findings of the study

Here are the findings form the metaanalysis. All the findings of patients suffering from loneliness and social isolation were in comparison to control groups without social deprivation.

  • There is a 32% all-cause mortality from loneliness and social isolation
  • Loneliness is responsible for a 14% increase in mortality compared to those who are not lonely
  • There is a 24% increased cancer mortality due to social isolation
  • Social isolation is responsible for a 34% increase of cardiovascular mortality
  • Socially isolated individuals with cardiovascular disease had a 28% increased all-cause mortality
  • Socially isolated women with breast cancer had a 51% increased all-cause mortality

Life style factors part of loneliness and social isolation

Turhan Canli, a professor of integrative neuroscience in the department of psychology at New York’s Stony Brook University had no involvement in the study. He said: ”People who feel socially isolated or lonely tend to have unhealthy habits, such as smoking, alcohol use, poor diet or little exercise. Having a small social network or little to no contact with the outside world can also make someone less likely to receive medical care if they don’t have anyone checking on them.”

Broadening social connections

We learnt how devastating loneliness and social isolation are for your health. It follows from this that the solution is to concentrate on broadening social connections as a preventative measure. Canli said: “Think of maintaining a social network like any other health-promoting activity: exercising regularly, eating well, looking after yourself.” Cultivate your social connections with a higher priority than in the past. Engage in new circles of like-minded people. Seek opportunities out like joining an exercise class or a discussion group.

Conclusion

Loneliness and social isolation are a real entity that threatens all of our health. A meta-analysis of 90 prospective studies (6 months to 25 years of follow-up) including more than 2 million people showed the following. There is a 32% all-cause mortality from loneliness and social isolation. Cancer mortality is up 24% due to social isolation. Socially isolated individuals with cardiovascular disease had a 28% increased all-cause mortality. Socially isolated women with breast cancer had a 51% increased all-cause mortality. There were more findings than these. Overall, this stresses the importance to cultivate your social connections, which prevents social isolation and loneliness. You will stay healthier for longer and not die prematurely.
