Immunosenescence - the decline of our immune system as we grow old

Nature has not meant for us to grow old. Nature simply wants us to reproduce ourselves; afterwards, she causes us to rapidly deteriorate. As we age, we are no longer able to run as fast as when we were young, we get tired more easily, it takes longer for our wounds to heal, etc. (many of those who are reading this are probably all too familiar with the aches and pains associated with growing old). If we were still living in the jungle, with predators all around us, those of us who are old would soon be “recycled.” Nature’s goal is the perpetuation of the species, so that resources, if limited, are saved for those who can contribute more toward the fulfillment of that goal. Nature has caused us (and other organisms) to be born with the conviction that those who compete for limited resources are best eliminated; alliances with those who enhance access to those resources are best formed. We apply the notion of competition and alliance not only to other species, but also to members of our own species. By Nature’s reckoning, the old, who are no longer able to contribute significantly to the welfare of the species and who now pose competition for resources, are best eliminated. Nature is so unfeeling.

But we defy Nature and we have developed means that allow us to grow old. We no longer fear the predators that used to chase us, hoping to feast on our flesh (we have killed most of them off). We have developed drugs that fight many of the parasites that plague us (but there are still very many that we have to get rid of, or at least control). We have developed mechanical means to allow the incapacitated to walk and even to run. We have developed electrical means to allow even the severely hearing impaired to hear. Indeed, more and more, we can grow very old despite Nature. (And we have learned to cherish the old — many of us, anyway.)

Ah, but Nature still has a few tricks up her sleeve.

Nature has provided us with the means to ward off disease, to fight organisms that cause disease. Our skin is a barrier that prevents entry of parasites and pathogens. The acid in our stomach usually can kill organisms that get in by way of our mouth. The tears in our eyes, the saliva in our mouth, and other secretions protect our other orifices. If viruses, bacteria, fungi, and other pathogens manage to get past those barriers, they will still have to contend with our immune system.

Our immune system is our ultimate protection against disease. We have cells and molecules that are specially designed to recognize substances that do not belong in our body. Immune cells and molecules patrol our organs and tissues, seeking out foreign substances. Germs and other pathogens are killed and the harmful molecules that they produce are neutralized and expelled from our body. Our immune system also gets rid of our own cells that have become abnormal, or are no longer functioning properly.

Very importantly, our immune system produces “memory cells” that remember previous encounters with a pathogen, so that the immune reaction to any new invasion is much faster. Immune memory is the rationale for vaccination — and for its success. Memory cells have been found to persist for more than 50 years in individuals who had been vaccinated against smallpox and for more than 90 years in survivors of the 1918 flu pandemic. Clearly, immune memory persists for many years and sometimes for a lifetime.

So, what does Nature do? To prevent us from getting (too) old, Nature weakens our immune system as we age — a condition called “immunosenescence” (immune aging). With the decline of our immune system, we more easily succumb to infection, we are more prone to cancer, we are more susceptible to seasonal diseases like the flu, etc., and vaccination, which we have invented to protect us from many diseases, becomes less and less effective.

For example, there were reports several years ago (in 2005 and 2006) of studies that showed that vaccination against flu of people 65 years old and older was not significantly protective. That finding was bolstered by a more recent finding (last year) that vaccination against flu of people over 70 years old did not reduce mortality. From these findings, it would seem that vaccination of the elderly is a waste. That is frightening, since 90 percent of flu deaths are of elderly individuals (who are more susceptible to pneumonia and other complications of flu).

Can we defy Nature one more time?

Vitamins present at Top Five Foods for Beating Depression

Top Five Foods For Beating Depression


By: Erin Bates



Drug advertisements and conventional doctors tell the public that depression is caused by an imbalance of a neurotransmitter in the brain called serotonin. This idea makes it seem that drugs that flood the brain with serotonin are the answer to depression, but there is no scientific evidence that drug therapy really works. In studies in which scientists lowered serotonin levels to induce depression, the experiment failed. Other studies found that dramatically increasing serotonin levels in the brain failed to relieve depression. So why do doctors persist in prescribing medications with side effects ranging from mood swings to suicidal or homicidal behaviors when those drugs may not even work?

There are treatment options that can relieve depression without swallowing pills. Many of the symptoms of depression can be directly linked to vitamin and mineral deficiencies in the standard American diet, which is largely comprised of empty carbs, caffeine and sugar. Depression, mood swings and fatigue often have a common cause: poor nutrition. Avoiding depression or recovering from a depressive episode is often as easy as changing your diet and boosting your consumption of key foods that deliver brain-boosting nutrients and help regulate brain chemistry.

Fish oils contain omega-3 fatty acids. Research has shown that depressed people often lack a fatty acid known as EPA. Participants in a 2002 study featured in the Archives of General Psychiatry took just a gram of fish oil each day and noticed a 50-percent decrease in symptoms such as anxiety, sleep disorders, unexplained feelings of sadness, suicidal thoughts and decreased sex drive. Omega-3 fatty acids can also lower cholesterol and improve cardiovascular health. Get omega-3s through walnuts, flaxseed and oily fish like salmon or tuna.

Brown Rice contains vitamins B1 and B3, and folic acid. Brown rice is also a low-glycemic food, which means it releases glucose into the bloodstream gradually, preventing sugar lows and mood swings. Brown rice also provides many of the trace minerals we need to function properly as well as being a high-fiber food that can keep the digestive system healthy and lower cholesterol. Instant varieties of rice do not offer these benefits. Any time you see "instant" on a food label, avoid it.

Brewer's Yeast contains vitamins B1, B2 and B3. Brewer's yeast should be avoided if you do not tolerate yeast well, but if you do, mix a thimbleful into any smoothie for your daily dose. This superfood packs a wide assortment of vitamins and minerals in a small package, including 16 amino acids and 14 minerals. Amino acids are vital for the nervous system, which makes brewer's yeast a no-brainer for treating depression.

Whole-grain oats contain folic acid, pantothenic acid and vitamins B6 and B1. Oats help lower cholesterol, are soothing to the digestive tract and help avoid the blood sugar crash-and-burn that can lead to crabbiness and mood swings. Other whole grains such as kamut, spelt, quinoa and buckwheat are also excellent choices for delivering brain-boosting nutrients and avoiding the pitfalls of refined grains such as white flour.

Cabbage contains vitamin C and folic acid. Cabbage protects against stress, infection and heart disease, as well as many types of cancers, according to the American Association for Cancer Research. There are numerous ways to get cabbage into your diet: toss it in a salad instead of lettuce, use cabbage in place of lettuce wraps, stir fry it in your favorite Asian dish, make some classic cabbage soup or juice it. To avoid gas after eating cabbage, add a few fennel, caraway or cumin seeds before cooking. Cabbage is also a good source of blood-sugar-stabilizing fiber and the raw juice of cabbage is a known cure for stomach ulcers.

Also worth mentioning, foods like raw cacao, dark molasses and Brazil nuts (high in selenium) are also excellent for boosting brain function and eliminating depression.

Things to avoid: If you feel you are depressed or at risk for depression, you also need to avoid certain non-foods and substances. Some commonly prescribed drugs - such as antibiotics, barbiturates, amphetamines, painkillers, ulcer drugs, anticonvulsants, beta-blockers, anti-Parkinson's drugs, birth control pills, high blood pressure drugs, heart medications and psychotropic drugs - contribute to depression. If you are taking any of these, don't quit them without talking to your doctor, but be aware that they may be contributing to your condition by depleting your body of depression-fighting vitamins and minerals.

You should also avoid caffeine, smoking and foods high in trans-fats and sugar. Keeping your blood sugar stable and getting B vitamins is important for stabilizing your mood. Cacao can be good for mood because it releases endorphins in the brain, but watch out for milk chocolate and candy varieties high in sugar.

Other non-food things to do: Get plenty of sunshine. Natural sunlight is a proven cure for depression. Engage in regular exercise at least three times per week.
Exercise lifts mood and alters brain chemistry in a positive way. Finally, experience laughter. It's good medicine.
