New FDA Food Guidelines

A recent news release describes 2016 new FDA food guidelines. In it the FDA recommends to double the amount of seafood (fish and shellfish) as well as to cut down saturated fat and sugar. Coffee, which was labeled a culprit in the past is now recommended to a total of 400 mg of caffeine per day as it is heart protective. Cholesterol is no longer considered an enemy, but sugar, saturated fats and trans fats are.

Here is a breakdown of what each of these recommendations means.

New FDA food guidelines regarding increasing fish and shellfish

The anti-inflammatory effects of omega-3 fatty acids have finally entered the recommended diet plan of the FDA. This reflects the nutritional research over the last few decades that noticed a longer life expectancy for people who eat more seafood and less red meat.

The only problem with seafood can be its mercury contamination. The higher predator fish are in the food chain, the more contaminated fish meat is. The FDA recommends to avoid tuna fish as a food source, as it is very high in mercury. An exception is canned tuna as it has been washed and some of the mercury got lost in the food processing. Wild salmon, sardines and oysters are low in mercury and good sources of omega-3 oils.

New FDA food guidelines regarding reduction of saturated fat

The FDA now recommend to reduce saturated fat to 10% of the total daily caloric intake. This is not undisputed as some studies show that saturated fat may not be involved in the production of hardening of the arteries. Other studies have shown that breast cancer is more common when more saturated fat is consumed.

When the news came out in the 1980’s that saturated fats would be bad for arteries, there was a switch to polyunsaturated acids: safflower oil, canola oil, sunflower seed oil, corn oil and soybean oil or grape-seed oil.

However, the irony is that these vegetable oils were highly unstable and led to oxidation causing heart disease and cancer.

In contrast olive oil is a much more stable oil. In the Mediterranean olive oil associates with longer lives.

New FDA food guidelines regarding protective effect of coffee

In the past few years many studies have shown the coffee consumption prolongs life. The FDA has now officially recognized these studies and recommends that consumption of up to 400 mg caffeine will help promote health. On the other hand the FDA also recommends that those who do not drink coffee, should not change their lifestyle just because of these recommendations.

New FDA food guidelines regarding sugar reduction

An entirely new recommendation of the FDA says to reduce sugar in anybody’s diet. The FDA explains that too many processed foods contain sugar. Food merchants  add sugar in drinks like coffee, fruit juices, food items like muffins and cakes.

In the past decades it has become clear that sugar much more so than fat is the culprit. It is sugar and starchy food that causes hardening of arteries. The liver metabolizes sugar into triglycerides and LDL cholesterol. Elevated triglycerides and LDL cholesterol levels lead to deposited into arteries and fatty tissue. In this context it makes sense that the FDA now recommends a reduction of sugar intake.

 New FDA food guidelines regarding cholesterol

In the past scientists thought that cholesterol in meat would be the cause of high cholesterol in the blood. This was an oversimplification. We now know that only a small portion of the blood cholesterol comes from food sources.  Cholesterol from food sources is no longer of importance with regard to risks for heart attacks and strokes. It is sugar and too many starchy foods (bread, pasta, pizza, muffins, cakes cookies) that the body digests into sugar. This accounts for high cholesterol, as the liver metabolizes sugar into LDL cholesterol and triglycerides.

New FDA Food Guidelines

Conclusion

The new food guide by the FDA has fundamentally changed the previous recommendations based on newer nutritional studies. Now the FDA says to double fish and shellfish in comparison to previous recommendations. Coffee is no longer the enemy, but your friend. You need to avoid sugar and starch over consumption, as this can raise cholesterol and triglyceride levels. Eat more vegetables and fruit. These recommendations closely resemble a Mediterranean diet, which several studies tell us prolong life. Abandon the American Standard diet with hamburgers, processed foods and sugary drinks. Pay attention to the FDA food recommendations!

Avoid BPA

After a lot of bad press as a hormone disruptor we know we should avoid BPA. Bisphenol A (BPA) is a synthetic compound that has been used since 1957 in plastic bottles and as lining inside cans, so they don’t rust.

Study showing why we should avoid BPA

Recently BPA has again hit the media as a new study has shown that there are things we can do to avoid high concentrations of BPA by changing our lifestyle.

This media report is based on a scientific study that Jennifer Hartl and coworkers have done. They followed patients who had consumed various items known to be contaminated with BPA and measured their urine BPA concentration 24 hours later. 9% of their study participants had consumed one can of food or more, while 2% had consumed 2 cans of food or more on the previous day. Researchers compared one can of food consumed to none. They found 24% of higher BPA concentration in the urine. With two cans of food consumed versus none they found that 54% of higher BPA concentration was found in the urine.

Researchers compared one or more specific types of canned foods to none consumed. Some interesting differences emerged. Canned vegetables and fruit showed 41% higher BPA in the urine test. Canned pasta measured 70%, but canned soup 229%. The researchers also tested canned beverages. None of them caused BPA elevation in urine tests.

What BPA does

93% of Americans 6 years and older have BPA in their urine indicating that it is in our bodies, and the body is attempting to get rid of it. It is known as an endocrine disruptor, but how effective BPA is as an endocrine disruptor remains to be seen. This link describes that BPA is 800-times weaker as an estrogen blocking substance in comparison to soy products.

There are two mechanisms of action where BPA interferes with normal body function.

  1. BPA functions as a weak estrogen and binds to the nuclear estrogen receptor. This partially blocks the action of the body’s own estrogen function.
  2. There is also a membrane based estrogen receptor on body cells that is involved in cell signaling and gene expression. BPA can add methyl groups to DNA, which silences gene expression. This latter mechanism is much more sensitive to BPA (probably by a factor of 1000-times) than the traditional effect on the nuclear estrogen receptor.

It is these newer findings that are of concern with regard to fertility in males. It is important that babies are not fed using regular plastic bottles, but rather that BPA-free bottles or glass bottles are used to avoid BPA exposure. Babies and children are particularly vulnerable to the hormone blocking effects of BPA as well as the interference of brain development and maturation by BPA.

Manufacturing of BPA free plastic

In an attempt to avoid BPA in manufacturing of plastic bottles and food containers industry has used other chemicals, among other materials something called BPS. This stands for “Bisphenol S”. A research paper found that BPS is an endocrine disruptor as much as BPA is and causes fat cells to grow rapidly. According to the author of this publication it may be partially responsible for the obesity wave. The author of this study recommends using glass containers as much as possible to avoid transfer of either BPA or BPS to food that comes in contact with plastic materials.

Avoid BPA from receipts

Have you ever thought that you may be able to absorb BPA through your skin from receipts when you buy items at a store? Yes, the machine of the checker prints receipts on heat sensitive paper. It contains BPA on it, which the body absorbs through the skin. If you scratch the printed part of the paper and it leaves a dark mark, it is thermal paper.

In this study workers were handling thermal receipts for four hours and their urine was monitored for BPA the following day. Another group was handling thermal receipts for 8 hours. In the first group that had exposure for 4 hours the BPA concentration in the urine rose to three times higher than the base rate. The second group exposed for 8 hours had BPA levels that were five times higher than the base rate. For comparison researchers measured another group that was wearing surgical gloves and their BPA concentration in the urine showed no change from the baseline.

I have changed my way of shopping. I think about whether I would ever want to exchange the item I just bought. If not, I tell the clerk that I do not want a receipt and he throw it out.

How you can avoid BPA exposure

  1. Do not use plastic containers to heat food in a microwave, use glass containers instead.
  2. Avoid all plastic food containers that have a “7” printed in a triangle on the bottom. Among these is a significant number that will release BPA over time.
  3. Avoid canned soups, such as tomato soup or canned mushroom soup. The paper reviewed at the beginning of this review showed these led to the highest BPA readings in urine tests the following day.
  4. Keep in mind that 2 out of 3 cans in supermarkets are positive for BPA. Eat as much fresh or frozen food as you can, but avoid canned food.
  5. Many canned beverages (such as beer, soda, juice) are acidic; this means that their thermal processing requirement is much different requiring lower temperature where BPA does not leach from the bottle into the stored fluid. These drinks when tested were BPA free.
  6. Among drinking water containers the following have been tested: Aquafina, Dasani, Arrowhead, Fiji and Kirkland Signature bottled water from Costco. They were all BPA free. Most water companies have now switched to BPA free containers, but avoid the containers with the “7” in a triangle as already stated, as some of them may leach BPA into the bottle content.
  7. Use fresh, unpackaged foods as much as possible. For instance, fruit and vegetables can often be had unpackaged. Check the packaging, check the type of plastic and if not sure, don’t buy it.
  8. Whenever possible, avoid handling thermal receipts; if possible, get an email receipt instead to avoid BPA exposure through the skin.
Avoid BPA

Avoid BPA

Conclusion

There has been a silent revolution where more and more plastic and resins have entered our lives. With it came the exposure to BPA, which is an endocrine disruptor. This may have consequences regarding male fertility. There is a change of fat metabolism in both sexes with weight gain as the end result. It also interferes with brain development in the fetus and in young children. BPA behaves like a cell poison.

In this blog I have shown ways to reduce exposure to BPA. We need to eat more fresh vegetables and fruit that merchants sell not in plastic. If merchants sell food in plastic or plastic containers, the wrapping material must be BPA and BPS free. The FDA and/or EPA must make labeling of containers mandatory. Whenever possible return to glass containers that are BPA free. Also bear in mind that heating plastics can release toxins. If you are heating food in a microwave, do not use plastic containers. Instead use glass or ceramics. It is common knowledge that they are safe!

Pain Treatment

General practitioners see a lot of patients with various pain symptoms for which they seek pain treatment. The underlying conditions might be from an arthritic problem that suddenly becomes symptomatic, or an acute back injury may send pain from the lower back into one of the legs. Others may experience excruciating headaches like migraines or tension type headaches. Often these painful conditions require some immediate pain relievers to treat the pain, but this can turn into a nightmare of drug dependency and may even lead to the development of chronic pain. Here I like to review an article that I found in the June edition of ConsumersReports.org.  In my review I included most of the content, but added a few newer pain treatment modalities.

Acute pain

Here I’m discussing back pain as an example. When a disc bursts in the lower back because the person was lifting an object too heavy to lift, acute pain develops in the lower back. This is often located at the lower lumbar spine level (L5/S1) causing radiating pain into one of the legs.

In a case like this it will often take several weeks before the body can heal this condition.

Chronic pain

It can happen in many cases that the pain will still be there 3 to 6 months down the road. If a disc fragment pushes on the nerve root in the nearby canal through which the nerve root travels, this will cause the muscles supplied by the nerve root to melt away in the leg of the affected side. If nothing is done about this, the acute pain turns into chronic pain, which is much more difficult to resolve. The initial physician may refer the patient to a neurosurgeon who will review the case together with the help of an MRI scan that shows the underlying pathology. The neurosurgeon may determine that a mini discectomy will reduce the pressure onto the nerve root.

Relief of pressure on nerve root from mini discectomy

This surgery may be able to prevent chronic pain from setting in. Once the pressure is relieved, the nerve can start the healing process. It is critical to not miss the point where acute pain crosses over into chronic pain. This happens at around 2 to 3 months into the pain condition. Chronic pain is much more difficult to treat as some of the neurological pain pathways that form after such injuries can persist within the spinal cord or even within the central nervous system, even after successful disc surgery that is done too late. With respect to the example given above, if the patient is operated on too late (1 to 2 years after the injury), the procedure may not be effective in relieving the pain. A chronic pain syndrome has started.

How pain treatment is done

  1. Avoid bed rest

In the past (up to the late 1970’s to mid 1980’s bed rest was the accepted initial mode of treatment. Even though patients often felt some relief of pain initially, this led to muscle atrophy (literally a melting away of muscles) in the muscles that are supporting the spine. These structural changes destabilized the spine and often made the pain more chronic until physiotherapy treatments and active exercises rebuilt the supporting muscles again.

  1. See a physiotherapist

Physiotherapists can use different treatment modalities like traction, a TENS machine, active exercises that all can help to alleviate back pain due to muscle spasm. If there is only a strain, this will often help to resolve your back pain within 4 weeks. But if there is an underlying disc herniation as previously explained, you need to be assessed by a physician in an urgent care center, primary care setting or by an emergency physician in the emergency department of a hospital. When the examination confirms an abnormal reflex from a nerve root compression, a referral to a neurosurgeon or orthopedic surgeon is usually made as previously explained.

  1. Chiropractic treatment

Some people have their backs treated periodically to prevent back troubles. When they get an acute back pain they likely will see the chiropractor again. In cases of a back strain, where one or more muscles are pulled, this approach will be helpful together with some home exercises and swimming to build up muscle strength along the spine. However, in the case of a herniated disc chiropractic adjustments should not be done (physicians say they are “contra-indicated”). Instead the patient should be referred to either a neurosurgeon or an orthopedic surgeon.

  1. Medication for pain

Often physicians prescribe Tylenol with codeine, hydrocodone (Vicodin), oxycodone (OxyContin, Percocet) or morphine for pain relief. All narcotic medication have side-effects; they can cause constipation, can cause vomiting, make you feel dizzy and can lead to falls, particularly in elderly patients. These falls can cause hip fractures and other fractures that complicate the recovery from the original pain. Never exceed the dosage of pain medicine prescribed on the label, and if it does not relieve the pain, see your physician again for a reassessment to rule out any complications.

Depression with back pain

Often people with back pain also have depression. To address this issue your physician may prescribe an antidepressant like duloxetine (Cymbalta), which has been approved by the FDA for treatment of lower back pain. But there are two rare, but important side effects to know about. Cymbalta can cause lowering of blood pressure, which leads to dizziness. This can cause serious falls with the danger of fractures. The other complication is the risk of liver failure.

Side effects of pain treatment

Pain pills can be addicting

While there seems to be an urgency to treat a patient who is in pain with pain medication, the treating physician must not forget that pain medication is potentially addicting and patients often use higher doses than advisable. However, pain medication has a narrow therapeutic window meaning that the toxic levels are not much higher than the drug levels necessary to relieve pain.

Some medications are only marginally effective

There are medications that are only marginally effective, if at all. Glucosamine and chondroitin are used for relief of arthritic pain in osteoarthritis sufferers. They are eliminated by a liver enzyme system that also eliminates blood thinners. If a patient is on blood thinners, the addition of glucosamine and chondroitin can lead to dangerous bleeding. Instead of using glucosamine and chondroitin when you experience pain and inflammation in joints, reduce your activities, but stay as active as you can to avoid your symptoms from getting worse.

Tests for severe migraines

When a patient has a severe migraine headache it is tempting to want to rule out a brain tumor. But a CT scan exposes the patient to dangerously high radiation doses that over time could cause brain cancer or leukemia. There are physical examination methods to rule out a brain tumor. If the findings are positive, an MRI scan can be used to get much more detail of the brain than a CT study would reveal. MRI scans do not have undesirable side effects.

Use gentle movement to remobilize the painful joints

Before you rush into using anti-inflammatory drugs, use gentle movement to remobilize the painful joint, back or limb. Activities like swimming, walking or yoga can reduce pain and allow you to recover from a painful condition according to a Cochrane Library analysis of 61 studies.

Non steroidal anti inflammatory drugs (NSADs)

For more pain relief NSAID (non steroidal anti inflammatory drugs) pain relievers like ibuprofen (Advil) or naproxen (Aleve) for a brief period will also help. The problem with long-term use of NSAIDs is that it can cause kidney damage. With longer use of NSAIDs there is also a danger of stomach bleeding, heart attacks and strokes.

Toxicity with Tylenol

The pain drug acetaminophen (Tylenol) has a narrow therapeutic window and is less effective in pain relief than the NSAIDs. The FDA has recommended as the highest daily dose 4000 mg of acetaminophen. But if you are a heavy drinker or you have liver disease, your daily dose of acetaminophen should not exceed 3250 mg to avoid liver toxicity. Long-term use of acetaminophen can also damage your kidneys, therefore the recommendation to use acetaminophen only for a short period of time (a few days).

Side effects of triptan drugs for migraines

Migraine headache drugs: The newer migraine drugs, called triptans temporarily narrow widened blood vessels. This relieves severe migraines within about 2 hours. However, these medications are not recommended for those with high blood pressure, chest pain, heart disease or circulation problems in the legs, as blood vessel constriction could bring on heart attacks or worsen circulation problems.

Common sense approach to pain treatment

The key for any pain condition is to treat the pain right away to minimize the impact that pain has on you and to prevent developing chronic pain, which is more difficult to treat.

Here are some examples.

Migraine headaches

If you have a migraine headache, use an over-the-counter pain reliever like naproxen or ibuprofen to treat the migraine pain very early. A combination of acetaminophen, aspirin and caffeine (like Excedrin Migraine or a generic copy) will also do. This will stop the release of prostaglandins, which would send pain signals to the brain. Heat packs or cold packs on your head can also help in the treatment of a headache. A 2013 study from Germany has shown that migraine sufferers can get rid of their migraine headaches in 60% by having sex. It sounds like a nice idea, but what they have not considered may be the fact that somebody who has a splitting headache is not feeling like sex at all!

Triptan pills for migraines

If your home remedies did not help, see your physician for one of the triptan pills. Sumatriptan or a similar drug constricts blood vessels to the brain. The doctor will also look for common triggering factors that can bring on a migraine. Weak neck and shoulder muscles may respond to physiotherapy strengthening. In women a condition called estrogen dominance is associated with migraines and can be treated with bioidentical progesterone to balance estrogen and progesterone in the body by elevating progesterone concentration.

Acute lower back pain 

Acute lower back pain usually follows an event where the person lifted something too heavy or injured the back from a fall. The important part is to rule out a fracture. Most of the time there is no underlying fracture, just a muscle strain. A muscle strain usually sorts itself out in time. Stay active as much as possible. But if the back pain does not resolve within a few days, see your physician for more tests. X-rays can delineate structural changes like a fracture. As explained earlier, an MRI scan can rule out a disc herniation. Instead of neurosurgery, further options nowadays are prolotherapy, stem cell therapy or a combination prolotherapy/stem cell therapy. This type of therapy will also work for knee injuries (meniscal or ligamentous tears).

Hip or knee pain

Conventional medicine usually treats osteoarthritis with NSAIDs, but may not warn you about the possibility of gastric erosions that can lead to massive stomach bleeding, heart attacks or strokes when using NSAIDs. It also can lead to kidney damage that can cause sudden kidney failure. The key is to use anti-inflammatory medication only for a few weeks. If arthritis persists, it is wiser to seek the advice of a naturopathic physician for prolotherapy treatment. One or two treatments of prolotherapy can give relief of pain. If prolotherapy does not succeed, it is best to move on to mixed stem cell therapy with bone marrow and mesenchymal stem cells (from fat cells) as well as PRP (platelet rich plasma). This usually leads to complete healing of osteoarthritis and eliminates the need of total knee or total hip replacement.

Neck and shoulder pain

This often develops because of poor posture, shoulder tendinitis or neck muscle spasm. Physiotherapy is often successful treating this. If not the physiotherapist can use intramuscular stimulation (IMS) with acupuncture needles. This may be more successful in interrupting the abnormal neuropathic pain pathways. Alternatively electro acupuncture with a TENS-like device can also be successful. The newest treatment modality is the Weber medical system using a low-dose laser applicator. Prolotherapy can also be used for shoulder and neck problems, if the ligaments are lax. It requires a lot of experience on behalf of the health professional to choose the right treatment protocol for the condition.

Tension headaches

Anxiety, stress and fatigue can all lead to tension headaches. Initially you may want to drink liquids, as dehydration is related to tension headaches. If your headache is still present after one hour, use naproxen or acetaminophen. Take a warm or cold shower and lie down with a cool cloth on your forehead. If you still have a headache, check with your doctor whether it is indeed a tension headache or a migraine. You may have jaw clenching or teeth grinding during your sleep. If your bite seems off, see a dentist. For stress control use relaxation techniques.

Other ways to treat tension headaches

Some suggestions sound mundane enough, but they can be effective: Get enough sleep, get enough exercise, and work on improving your posture. A physician trained in trigger point injections with local anesthetics (often anesthetists or general practitioners) can freeze your suboccipital and supraorbital nerves with lidocaine, which I have seen to work in 60% to 70% of cases in my former practice.

Pain Treatment

Pain Treatment

Conclusion

Pain treatment can be confusing as pain itself can be very multifaceted. The key is to search for the cause of the pain. Then treat pain very quickly. This way it has time within 2 to 3 months to turn into a chronic pain condition. Chronic pain is much more difficult to treat. The physician should treat acute pain successfully. Conventional medicine has to yet learn from naturopathic medicine and alternative medicine practitioners. They use prolotherapy, stem cell therapy, IMS and trigger point injections with local anesthetics.  In addition low-dose laser therapy (Weber medical system) are valuable alternative methods to treat pain. These methods can successfully treat pain conditions. The physician can incorporate them into general medical practice.
