Most people feel down, tired and inactive when they’re injured or ill. This “sickness behavior” is caused by the activation of the body’s immune response. It’s the brain’s way of conserving energy so the body can heal.

This immune response can also occur in people with depression. This has prompted some researchers and clinicians to hypothesise that depression is actually a side effect of the inflammatory process.

But while there may be a connection between inflammation and depression, one doesn’t necessarily lead to the other. So it’s too simplistic to say depression is a physical, rather than a psychiatric, illness.

The inflammation hypothesis

University of California clinical psychologist and researcher George Slavich is one of the key recent proponents of depression as a physical illness. He hypothesises that social threats and adversity trigger the production of pro-inflammatory “cytokines”. These are messenger molecules of the immune system that play a critical role in orchestrating the host’s response to injury and infection.

This inflammatory process, Slavich argues, can initiate profound behavioral changes, including the induction of depression.

The idea that the activation of the immune response may trigger depression in some people is by no means a new one. Early descriptions of post-influenza depression appeared in the 19th century in the writings of English physician Daniel Tuke.

But it was not until the 1988 seminal paper, published by veterinarian Benjamin Hart, that the phenomenon of acute “sickness behavior” caught the interest of the scientific community.

Hart described his detailed observations of the “behavior of sick animals”. During acute infection, and in response to fever, the animals sought sleep, lost their appetite, showed a reduction in activity, grooming and social interactions, as well as showing signs of “depression”.

Just like the immune response itself, these changes reflect an evolved survival strategy that shifts priorities toward energy conservation and recovery.

Putting the theory into practice

Cytokine-induced sickness behavior has subsequently been studied as an example of communication between the immune system and the brain.

The behavioral changes during sickness resemble those associated with depression, so it didn’t take long for researchers to make a connection between the phenomenon of sickness behavior and mental disorders.

Such speculation was strengthened by research showing that depressive states can be experimentally induced by administering cytokines and other immunogenic agents (such as vaccines) that cause an inflammatory response.

Depression is frequently associated with inflammatory illnesses such as heart disease and rheumatoid arthritis. It’s also a side effect of treatment with cytokines to enhance the immune system.

Over recent decades, researchers have made progress in understanding how inflammation may impact on the activity of signalling pathways to and from the brain, as well as on the functioning of key neural systems involved in mood regulation.

But there’s not always a link

From the available evidence it’s clear, however, that not everyone who suffers from depression has evidence of inflammation. And not all people with high levels of inflammation develop depression.

Trajectories of depression depend on a complex interplay of a spectrum of additional risk and resilience factors, which may be present to varying degrees and in a different combination in any individual at different times. These factors include the person’s:

  • genetic vulnerabilities affecting the intensity of our inflammatory response
  • other medical conditions
  • acquired hyper-vigilance in the stress response systems due to early life trauma, current adversities, or physical stressors
  • coping strategies, including social support
  • health behaviors, such as sleep, diet and exercise.

Implications for treatment

In line with the notion that inflammation drives depression, some researchers have already trialled the effectiveness of anti-inflammatory therapy as a treatment for depression.

While some recipients (such as those with high levels of inflammation) showed benefit from the treatment, others without increased inflammation did not. This supports the general hypothesis.

However, in our desire to find more effective treatments for depression, we should not forget that the immune response, including inflammation, has a specific purpose. It protects us from infection, disease and injury.

Cytokines act at many different levels, and often in subtle ways, to fulfill their numerous roles in the orchestration of the immune response. Undermining their vital role could have negative consequences.

Mind versus body

The recent enthusiasm to embrace inflammation as the major culprit in psychiatric conditions ignores the reality that “depression” is not a single condition. Some depressive states, such as melancholia, are diseases; some are reactions to the environment; some are existential; and some normal.

Such separate states have differing contributions of biological, social and psychological causes. So any attempt to invoke a single all-explanatory “cause” should be rejected. Where living organisms are concerned it is almost never that simple.

In the end, we cannot escape the reality that changes must occur at the level of the brain, in regions responsible for mood regulation, for “depression” to be experienced.

5 foods that fight high cholesterol

It’s easy to eat your way to an alarmingly high cholesterol level. The reverse is true too — changing what you eat can lower your cholesterol and improve the armada of fats floating through your bloodstream. Fresh fruits and vegetables, whole grains, and “good fats” are all part of a heart-healthy diet. But some foods are particularly good at helping bring down cholesterol.

How? Some cholesterol-lowering foods deliver a good dose of soluble fiber, which binds cholesterol and its precursors in the digestive system and drags them out of the body before they get into circulation. Others provide polyunsaturated fats, which directly lower LDL. And those with plant sterols and stanols keep the body from absorbing cholesterol. Here are 5 of those foods:Fruits and veggies in heart tape

  1. Oats. An easy way to start lowering cholesterol is to choose oatmeal or a cold oat-based cereal like Cheerios for breakfast. It gives you 1 to 2 grams of soluble fiber. Add a banana or some strawberries for another half-gram.
  2. Beans. Beans are especially rich in soluble fiber. They also take a while for the body to digest, meaning you feel full for longer after a meal. That’s one reason beans are a useful food for folks trying to lose weight. With so many choices — from navy and kidney beans to lentils, garbanzos, black-eyed peas, and beyond — and so many ways to prepare them, beans are a very versatile food.
  3. Nuts. A bushel of studies shows that eating almonds, walnuts, peanuts, and other nuts is good for the heart. Eating 2 ounces of nuts a day can slightly lower LDL, on the order of 5%. Nuts have additional nutrients that protect the heart in other ways.
  4. Foods fortified with sterols and stanols. Sterols and stanols extracted from plants gum up the body’s ability to absorb cholesterol from food. Companies are adding them to foods ranging from margarine and granola bars to orange juice and chocolate. They’re also available as supplements. Getting 2 grams of plant sterols or stanols a day can lower LDL cholesterol by about 10%.
  5. Fatty fish. Eating fish two or three times a week can lower LDL in two ways: by replacing meat, which has LDL-boosting saturated fats, and by delivering LDL-lowering omega-3 fats. Omega-3s reduce triglycerides in the bloodstream and also protect the heart by helping prevent the onset of abnormal heart rhythms.

But stay away from…

As you consider eating more of the foods that can help dial down cholesterol, keep in mind that avoiding certain foods can improve your results. To keep cholesterol levels where you want them to be, limit intake of:

Saturated fats. The saturated fats found in red meat, milk and other dairy foods, and coconut and palm oils directly boost LDL. So one way to lower your LDL is to cut back on saturated fat. Try substituting extra-lean ground beef for regular; low-fat or skim milk for whole milk; olive oil or a vegetable-oil margarine for butter; baked fish or chicken for fried.

Trans fats. Trans fats are a byproduct of the chemical reaction that turns liquid vegetable oil into solid margarine or shortening and that prevents liquid vegetable oils from turning rancid. Trans fats boost LDL as much as saturated fats do. They also lower protective HDL, rev up inflammation, and increase the tendency for blood clots to form inside blood vessels. Although trans fats were once ubiquitous in prepared foods, many companies now use trans-free alternatives. Some restaurants and fast-food chains have yet to make the switch.
