Cancer in younger Adults is due to Accelerated Aging

By | alcohol, Cancer, Cardiovascular disease, diet, Heart Disease, Mortality, Processed food, telomeres

Recent research showed that cancer in younger adults is due to accelerated aging. Researchers presented a paper at the American Association for Cancer Research (AACR) Annual Meeting 2024. They discussed in detail how cancer presents in aging tissues.

Details of the study

Researchers examined the UK Biobank databases of 148,724 individuals aged 37 to 54 years. 9 biomarkers from blood of these patients served to calculate the biological age of these patients. The following were the blood tests: albumin, alkaline phosphatase, creatine, C-reactive protein, glucose, mean corpuscular volume, red cell distribution width, white blood cell count, and lymphocyte proportion. I will discuss below how they calculated the biological age from these factors. In most patients there was a discrepancy between the chronological age and the biological age.

The researchers also checked the cancer registries to check how many cancer patients were found before age 55. Nearly 3200 cancers were found. Patients born between 1950 and 1954 were compared to patients born in or after 1965. Surprisingly the younger patients (born in or after 1965) had 17% higher accelerated aging. This made this group more prone to develop early cancers.

Significance of accelerated aging regarding cancer frequency

The researchers also found that increases in accelerated aging were associated with a significant risk of early-onset lung cancer, early-onset gastrointestinal cancer, and early-onset uterine cancer. Individuals who had the highest amount of faster aging were compared to people who had the smallest amount of faster aging. The faster aging group had twice the risk of early-onset lung cancer, more than 60% higher risk of gastrointestinal tumors, and more than 80% higher risk of uterine cancer.

Calculating the biological age 

The following is a list of items to calculate the biological age (taken from this CNN source):

  • albumin: a protein made by the liver that declines with age
  • creatinine: a waste product in blood produced by protein digestion and the breakdown of muscle tissue; a measure of kidney function. Lower levels correlate with better longevity.
  • glucose: With age, blood sugar stays higher for longer after meals.
  • c-reactive protein: made by the liver in response to inflammation; relatively higher levels correspond to faster aging
  • lymphocyte percent: The concentration of these white blood cells related to immune function tends to decrease with age.

More items to calculate biological age:

  • mean cell volume: a measure of the average size of red blood cells, which increases with age
  • red cell distribution width: the difference between the size of a person’s smallest and largest red blood cells, which tends to increase with age
  • alkaline phosphatase: an enzyme produced mainly by the liver and bones that tends to increase with age
  • white blood cell counts: Numbers of white cells in the high end of the normal range in the blood may correspond with greater aging.

Using these criteria, a research group developed the algorithm PhenoAge. This is how the biological age was calculated.

What factors lower the biological age?

There are 8 essential components that determine your biological age: diet, physical activity, avoiding nicotine exposure, sleep health, lower body mass index (BMI), cholesterol, blood sugar, and blood pressure. This link states that when you optimize this list of 8 essential components your biological age will be 6 years less than your chronological age. It will make you resistant to several diseases including cancer.

Your telomere length is important to reduce your biological age

Researchers know for some time that telomere length determines the biological age. Telomere length determines how old we get. It also can predict whether we get illnesses like cancer and cardiovascular diseases as we age. In addition, it determines whether you get the blessing of longevity or not. Researchers showed that two lifestyle habits, namely a Mediterranean diet and regular exercise, preserve our telomeres to give us a younger biological age.

Effect of Junk foods on our biological age

Too many people eat unhealthy foods like processed meats, French fries, hamburgers and other processed foods. How does this affect your lifespan? When we consume unhealthy foods and beverages, like sugar-sweetened beverages and highly processed foods, we gain weight. Obesity and other chronic conditions are the results that put us at a higher risk regarding at least 13 types of cancer. Included in this are endometrial (uterine) cancer, breast cancer in postmenopausal women, and colorectal cancer.

How can we counter the devastating effect of highly processed foods?

We need to buy whole foods that were not processed. Buy fresh vegetables, fruit, nuts, organic chicken, fish like wild salmon.  Cook your own meals. This link describes anti-aging foods that help you to enjoy a longer life with less diseases. Other studies showed in the past that this type of food preserves your telomeres, prevents many cancers and prevents heart attacks and strokes.

Discussion

The study in the beginning of this review showed a higher cancer frequency in younger patients. This is a new concerning trend. But the study failed to show the reason behind this. In my opinion it is the fact that younger people nowadays have poorer lifestyles than in the past. They consume junk foods and larger amounts of alcohol regularly. This behavior pattern causes shortening of telomeres, lowering of the biological age and the emergence of diseases mentioned above. We need more research into the causes of telomere shortening in younger patients. Also, why do they experience accelerated aging with an increase in the biological age? The research paper shown in the beginning of this review was done on a British population.

There is a need for other studies

A similar study with a more diverse population including a record of their eating habits would be welcome. Apart from measuring the biological age, measuring the telomere length would also be useful. In addition, a control group of younger people who consume healthy foods would help as a contrast. This control group likely would have a lower biological age and longer telomeres than the experimental group.

Conclusion

In the beginning of this review, I described a study about younger patients. They had an accelerated biological age with a higher rate of various cancers. I showed that other researchers examined telomere length and the longer it was the less cancer the patients got. I mentioned that eating junk foods, processed meats and consuming sugary drinks was bad for your health. This accelerates your biological age and shortens your telomeres. As this study was based on a British cohort, we need new research that concentrates on a more diversified population. Apart from measuring the biological age, measuring the telomere length would also be useful. In addition, a control group of younger people who consume healthy foods would help as a contrast. This control group likely would have a lower biological age and longer telomeres than the experimental group.

Regular Exercise Makes you 9 years younger

By | diet, fish oil, green tea, lifestyle, Mortality, omega-3 fatty acids, telomeres

A recent publication noted that regular exercise makes you 9 years younger. The researchers meant that the biological age is 9 years younger than your chronological age. They went one step further and proved that regular exercise elongates your telomeres, which is why people who exercise regularly live longer. Specifically, they found that sedentary people had 140 fewer base pairs at the endpoints of their telomeres compared to people who engaged in regular physical activity. In other words, the biological age of a person who exercises regularly is lower than that of a sedentary person. This difference can be measured in leukocyte telomeres. With regard to the base pairs contained in telomeres the highest physical activity group showed the most elongation of the telomeres. There was a 9-year difference in terms of biological age between the highest exercise group and the sedentary group.

Other means of elongation of telomeres

Apart from regular exercise lifestyle factors can also modify the length of telomeres.

Smoking, a lack of regular exercise, exposure to stress and intake of polyunsaturated omega-6 fatty acids, especially linoleic acid shortens our body telomeres. Soybean oil, sesame seed oil, walnut oil and cotton seed oil are containing 45 to 50 % of linoleic acid, and for this reason should be avoided. The antioxidant effect of omega-3 fatty acids elongates telomeres by reducing the rate of telomere shortening. Antioxidants like vitamin E, vitamin C, beta-carotene were associated with longer telomeres and a lower risk to develop breast cancer.

A few dietary recommendations

Here are a few healthy food recommendations that will elongate your telomeres.

  • Include antioxidants, fiber, organic soy protein and healthy fats (derived from avocados, fish, and nuts).
  • Stay lean, active, healthy, and stress-free.
  • Eat foods such as salmon, herring, mackerel, halibut, anchovies, cat-fish, flounder, flax seeds, chia seeds, kiwi, black raspberries, lingonberry, green tea, broccoli, sprouts, red grapes, tomatoes, olive fruit, and other vitamin C-rich and E-rich foods. They are a good source of antioxidants. Avoid tuna and grouper fish (too rich in noxious mercury).
  • These combined with a Mediterranean type diet containing fruits, and whole grains will help protect your telomeres.
  • There are certain individuals who live longer than the rest of us. They may have a certain advantage, which is a longevity gene that makes the telomeres longer. Resveratrol also works through elongation of telomeres.

Telomerase can also lead to telomere length

I attended the 22nd Annual World Congress on Anti-Aging Medicine In Las Vegas (Dec. 10-14, 2014) that dealt with telomere length and how nutrition can positively influence what our genes express. This ultimately determines how long we live. Dr. Al Sears gave one of the talks at the conference.

He pointed out that shortened telomeres are causing cells to behave like old cells. In the lab we can lengthen telomeres. Telomerase activated animals regrew their brains! In the human situation the goal is to find ways to preserve the length of our telomeres in all our key organs. Alternatively, this can also be reached by inhibiting the breakdown of the enzyme telomerase, which will lead to a lengthening of telomeres. In his research Dr. Sears found at least 123 nutrients, vitamins and natural compounds that will elongate telomeres, often by stimulating telomerase.

Lengthening of critically shortened telomeres

Testing for critically short telomeres is clinically more important than using average telomere length tests. Dr. Sears said when a patient has been shown to have short telomeres and this patient is started on telomerase stimulating supplements, telomere lengthening can be documented within one month of starting the supplementation. Acetyl-L-carnitine and resveratrol are two substances that reliably elongate telomeres.

Vitamin C and other telomerase stimulators

Vitamin C will significantly delay shortening of telomeres, which translates into delayed aging. Age-dependent telomere shortening is slowed down by enrichment of intracellular vitamin C via suppression of oxidative stress. In addition, vitamin C has recently been shown to stimulate telomerase activity in certain stem cells. There is an herb, called Silymarin extract, which was found to increase telomerase activity threefold. N-acetyl cysteine is a building block for glutathione, a powerful antioxidant. In addition, it has been shown to turn on the human telomerase gene. Other telomerase stimulators are green tea extract, ginkgo biloba, gamma tocotrienol (one of the components of the vitamin E group), vitamin D3 and folic acid. Telomerase Inhibitors from Natural Products and Their Anticancer Potential.

Regular Exercise Makes you 9 years younger

Regular Exercise Makes you 9 years younger

Conclusion

A research paper found that regular exercise makes a person 9 years younger in terms of the biological age. The underlying process is that telomeres get longer with regular exercise. Specifically, the researchers found that sedentary people had 140 fewer base pairs at the endpoints of their telomeres compared to people who engaged in regular physical activity. I listed other factors that elongate telomeres and help with longevity. When you combine regular exercise with dietary factors that also elongate telomeres, you are better off than with exercise alone.

Any Form of Exercise is good

By | Cancer, Cardiovascular disease, diet, exercise, Fitness, Health, heart attack, Mortality

Here are a few items that can prolong life; among them any form of exercise is good. This article concentrates on the exercise part in relation to longevity. A recent publication described how regular exercise prolongs your long-term survival. According to a study released on occasion of the American Heart Association’s Scientific Session 2023 there are 8 major factors that prolong life: healthy diet, physical activity, nicotine exposure, sleep health, BMI, cholesterol, blood sugar, and blood pressure.  Among this group of factors regular physical activity plays a major role to prolong your life. Researcher who studied various people found that those who neglected their physical health had a chronological age of 53, but their average biological age was 57. On the other hand, a group of fit people who engaged in regular physical exercise had a chronological age of 41 years, but a biological age of 36.

Clinical trials showing that any form of exercise is good

JAMA Internal Medicine study by Dr. del Pozo Cruz 

This study examined what the optimal amount of physical activity per week is to reduce mortality compared to an inactive population. 500,705 eligible US adults were observed for about 10 years. The abbreviations that the authors used in the study were as follows:

MPA: moderate aerobic physical activity

VPA: vigorous aerobic physical activity

MSA: muscle-strengthening activity

Results of mortality reduction with various amounts of physical activity

  • The best group engaged in more than 0 to 75 minutes of MPA combined with more than 150 minutes of VPA and 2 or more MSA sessions per week. Their mortality rate was 50% lower than an inactive comparison group.
  • The optimal combination for reduction of cardiovascular disease (CVD) and cancer mortality risk was as follows: more than 150 to 225 minutes of MPA, more than 0 to 75 minutes of VPA, and 2 or more MSA sessions per week. This reduced combined mortality of CVD and cancer by 70%.
  • The researchers stated that the adjusted mortality rates represented 50% lower mortality rate for all-cause and cancer mortality. The mortality rate for CVD mortality was 3-fold lower than for inactive controls.

Smallest amount of exercise that reduces mortality

In a study published in the European Heart Journal the authors asked how little exercise per week was enough to reduce mortality from heart disease. They found that it takes at least 15–20 min/week of vigorous physical activity (VPA) to reduce mortality from heart attacks by 16–40%. If you increased the exercise level by 50–57 min/week the mortality rates reduced even further.

Are physically active jobs healthy?

Recent research showed that people who work in physically demanding jobs are more likely to develop early cognitive impairment. This is the pre-stage of Alzheimer’s disease. 15.5 % of people who worked in high levels of occupational physical activity developed dementia. This compared to 9% risk for people whose work involved a low level of physical activity, not too much and not too little. The finding confirms the notion that there is a need for balance of physical exercise. Several publications stressed what is optimal in terms of exercise: vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week). People who expose themselves to these amounts of exercise live the longest and stay healthy.

Discussion

The studies discussed here showed that the right amount of exercise can reduce mortality from heart disease and cancer. However, exercise is not the only factor that can do this. It is important to combine regular exercise with a healthy diet. Your diet should consist of fruits and vegetables, whole grains, low-fat dairy products, lean proteins and limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight, manage your stress, and don’t smoke.

Any Form of Exercise is good

Any Form of Exercise is good

Conclusion

In this review I touched on the importance of regular exercise to reduce mortality from heart disease and cancer. Vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week) reduce mortality from heart attacks by 16% to 40%. But physical exercise is only one factor of mortality reduction. If you want the full benefit from other factors, you must quit smoking, eat a Mediterranean type diet with fruits and vegetables, whole grains, low-fat dairy products and lean proteins. Also you should limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight and manage your stress. Once you adopted this lifestyle, you live longer and you will get less diseases.

Biological Age Is Different From The Chronological Age

By | alcohol, Alzheimer’s disease, andropause, blood test, cholesterol, diet, exercise, food, Health, heart attack, lifestyle, osteoarthritis, stress, Stroke, telomeres

Biological age is different from the chronological age said professor Morgan Levine from Yale Medical School. She is working in the department of pathology. She has found in her research that people of the same chronological age have very different biological ages. From a biological standpoint they may be much younger or older than their chronological age. When people are younger than their chronological age, they have less disease and less mortality. This article has reviewed the facts.

Measuring biological age

Dr. Levine also has developed tools how to determine the biological age. And when the biological age is higher than the chronological age, she recommends lifestyle changes that will set back the biological clock. We age differently according to what we eat, how our genetic make-up is, which we cannot change, whether we are physically active and what environmental toxins we are exposed to. So, the biological age determines our health status and what our final life expectancy will be.

Biomarkers for biological age

A simple blood test that your family doctor can order consists of the following. A fasting blood sugar, kidney and liver tests, immune tests and inflammatory tests. In addition the doctor will want to know whether you are smoking or not, how much alcohol you consume and how much red meat and processed meat you eat. A computer program processes these results, which determines your biological age.

Lifestyle improvements can lower biological age

Biological age testing has a strength built in. By changing your lifestyle you can lower it. When you exercise more regularly and switch to eating a Mediterranean diet you can lower your biological age. Other studies have shown that the Mediterranean diet is anti-inflammatory. A telomere test, which also determines the biological age, is fixed. It is not easily changed by dietary measures and increasing your exercise.

Dr. Levine said: “I think the most exciting thing about this research is that these things aren’t set in stone.”

Putting the biological age to the test

Dr. Levine was curious what her own biological age was. She entered her blood test data and lifestyle facts into the computer. She was surprised that her biological age was not as good as her first assumption. Now she is trying to get more sleep, has increased her exercise level and improved her diet.

Her research team is working on getting the algorithm online so that everyone will be able to put one’s blood tests and other data into the computer program and calculate the biological age. The program will also recommend what steps are likely most helpful to increase one’s health and decrease the biological age.

Lower your biological age

No one wants to live a long life, if they are in pain and have various illnesses like arthritis or Alzheimer’s. But things are different, if they can change lifestyle factors and maintain a low biological age for a long time. Now they can stay active, have no pains and are able to contribute to society.

“By delaying the onset of diseases and cognitive and physical functioning problems people can still be engaged in society,” Dr. Levine said. “I think that is the ideal we should be striving for.”

Other literature about biological age

Inflammation increases the biological age

In this publication the authors stressed that inflammation is the common denominator for developing disease and premature aging. The authors stress further that it is mandatory to change one’s lifestyle to lower the biological age and live longer.

Diastolic blood pressure predicts mortality

In an older study the diastolic blood pressure was related to mortality. The higher the diastolic blood pressure was, the higher the mortality.  The authors also noted that it was the persons with the higher biological age who were at the highest risk of dying.

Scientific study about the predictors for the biological age

Here is a scientific study that examines predictors for the biological age.  This is not easy reading, but I placed it here for completeness sake.

Link to a site that can calculate your biological age

Here is a link to a site that calculates your biological age. It is probably not as good as Dr. Levine’s computer analysis will be when it is available. However, it is a good approximation to what it will be like.

Biological Age Is Different From The Chronological Age

Biological Age Is Different From The Chronological Age

Conclusion

The dream of staying younger for longer is not new. Research has shown that we actually can do something about it. If we look after our lifestyle, don’t smoke, don’t drink excessively, eat a sensible Mediterranean-type diet and exercise regularly, our biological age will be less than our chronological age. It is the biological age that determines how old we get and whether or not we will suffer from age-related illnesses. Researchers also found out that when your biological age is younger than your actual age mortality will occur later. The math is simple. Let’s assume that your biological age is 15 to 20 years younger than your chronological age. As the average life expectancy presently is 80 years, your life expectancy can increase to 95 or 100 years.
