Peanuts & Peanut Butter

By Ben Fuchs | Pharmacist Ben

The PeanutThere is no food that speaks to the American childhood experience more clearly than the peanut, the source of that quintessential piece of culinary Americana, peanut butter. Peanuts were originally cultivated in South America by Peruvian Indians who are considered to be the first indigenous groups to domesticate the legume and archaeologists have traced the original specimens to around 5000 BC. From South America the Spanish brought the humble bean to Europe and to their colonies and outposts in what is today the south eastern part of the United States.

Peanuts really caught on during the civil war because they considered to be good, cheap protein. Farmers in the South had pretty much depleted their land of vital nutrients over farming cotton the lowly peanut had come to the rescue as an alternative crop. During and after the civil they ended up in the Northern states where they were sold, freshly roasted by street vendors in NYC and Boston and Philadelphia and a new American love affair was born.

Farming peanuts was a limited and labor intensive affair until the industrial revolution began to change agriculture around the turn of the 20th century. Right around that time George Washington Carver was developing all kinds of stuff from the peanut. All told, Carver, who was the head of the agricultural department at Tuskegee Institute, developed 300 different products with the peanut including various types of soaps and cleansers and milk and even ink! The reason Carver could make so many things out of the peanut is because there are so many incredible chemical active compounds in the plain old peanut.

Their complex nature is also is why peanuts can be such a problem food. In addition to the potentially thyroid suppressing compounds in peanuts, along with grains, dairy, and eggs are one of the most important of all food allergens. While peanut allergies are not as pervasive as as significant as dairy or grain the affect up to 6 million Americans and they be potentially life threatening. I remember when I was a pharmacy student working at an asthma hospital, a kid got an injection that was made with peanut oil and had an allergic reaction that was so severe it killed him. Peanuts can also be source of a toxic mold called aflatoxin that’s been associated with cancer. And unfortunately, peanuts are also a source of really problematic compounds called lectins that trigger various immune and autoimmune reactions.

One of the more common yet underappreciated reactions to peanuts involves the skin. For some sensitive folks, dermatitis can occur by simply by touching or breathing in peanut dust. And ingestion of peanuts has been linked to acne in susceptible children and teenagers.

If you’re looking for concentrated nutrients however, and you’re not concerned with allergic reactions, you’d be wise to add a handful or two of peanuts to a meal a couple of times a week. You can also throw some into a smoothie to enhance its nutritional value. Peanuts are a good source of protein and vitamins, including hard to find vitamin E (one ounce of peanuts contains 29% of the Reference Daily Intake level) as well as minerals like copper, phosphorous, magnesium, iron, potassium, selenium, zinc and calcium. All told, a couple of tablespoonfuls of peanuts contains nearly half of the 13 vitamins necessary for the body’s growth and maintenance and more than one third of the 20 minerals needed! Peanuts are even a good source of resveratrol; one ounce contains approximately 73 mg. A naturally occurring plant compound resveratrol intake is associated with a reduced risk of heart disease and increased longevity.

Coconut Oil and the Miracle Lipid that Burns Fat

By Ben Fuchs | Pharmacist Ben

One of my favorite nutritional supplements are medium chain triglycerides. Generally referred to as MCT oil, this largely unrecognized supplement imparts numerous benefits. MCT oil was first introduced almost 60 years ago as a tool for treating lipid disorders. MCTs are metabolized without bile and go directly to the liver where they are processed into a source of fuel. Thus they provide a good source of easily metabolized energy for patients with liver disease, gall bladder issues, those with bile deficiencies and other health compromised patients.

Coconut OilThey’re so effective that they’re the fuel of choice for hospitalized patients being fed intravenously in intensive care units. And MCTs may provide circulatory benefits too. A 2008 study published in The American Journal of Physiology found that MCT intake in rats with high blood pressure improved their cardiac function and structure.

Perhaps the most significant role MCTs provide for good health is in the realm of weight loss. Diet conscious health enthusiasts can benefit from MCTs unique metabolic chemistry in three ways. First of all, MCTs provide drive lipid biochemistry with 10 per cent fewer calories than ordinary fat. Secondly, MCTs are rapidly converted into energy. This means that they are much more likely than other fats to be uses as a source of fuel, rather than being stored. In this manner they function more like carbohydrates than fats. Yet, in contrast to carbs, they have no significant effect on insulin. This makes them an ideal source of energy for diabetics. Thirdly, unlike ordinary lipids, MCTs have been shown to increase thermogenesis (fat burning), which may result in an actual loss of calories.

In addition to providing weight reduction benefits, MCT oils have neurological enhancing properties. The fascinating fats been shown to increase the production of “ketones” which may provide benefits for senescent brains. Ketones are known as a potent and stable non-sugar source of energy to the brain. This makes MCT oils an ideal alternative brain fuel source for elderly and neurologically impaired patients, as well as diabetics (who are a much higher risk of age-related cognitive impairment), all of whom must be wary of the deleterious effects of sugar.

These unusual lipids have also been shown to increase the phospholipid levels in the brain which may provide additional cognitive benefits. And, interestingly, a 2009 study from the University of Toronto Department of Pharmacology and Toxicology found that supplementation with medium chain triglycerides improved the cognitive function in dogs and increased the level of omega-3 s in the parietal lobe of the brain, the section associated with the mental decline seen in human patients afflicted with Alzheimer’s disease.

Perhaps the most important food source of MCT oils is coconut oil. Besides being a wonderful ingredient for cooking, over half of the fats in this tasty oil are MCTs. If being used for its MCT content, a typical daily dose of coconut oil would be 2-4 tablespoons a day. Diabetics or Alzheimer’s patients can may want to take twice that much.

Occasionally, some patients find that coconut oil causes some stomach distress. Thus, when starting a coconut oil regimen, it’s probably best to start off using ½ to 1 tablespoonful a day and gradually work yourself up to a final 2-8 tablespoonful daily dose. Sometimes digestive discomfort from coconut oil can be alleviated by taking it with food. Other sources of MCTs include butter and palm kernel oil. Pure MCT oil is also readily available as a nutritional supplement in health food stores.

The Magic of Manganese

By Ben Fuchs | Pharmacist Ben

One of the least well-known essential trace minerals is manganese. This metallic nutritional element, which derives its moniker from the Greek word for magic, is present in almost all diets in low concentrations. Although these days it is mostly used as an alloy in stainless steel for its rust protection properties, manganese’s essential role in human nutrition should not be overlooked.

The Magic of Manganese

Black-Eyed Peas Curry, rich in manganese. (akshayapatra.blogspot.com)

The average human body contains about 10 milligrams of manganese, mostly concentrated in the liver, bones and kidneys. While deficiencies of manganese are typically uncommon, its highly charged electrical nature make this critical mineral unstable to milling of grains and other modern food processing techniques. According to Dr. E. Blaurock-Busch of Trace Minerals International, patients being fed intravenously may also be at risk for manganese deficiency, although some say there is some controversy surrounding the inclusion manganese to parenteral protocols. High doses of Manganese have been associated with neurotoxicity and Parkinson’s disease-like symptoms and current opinion regards the addition of manganese to parental solutions as unnecessary.

What is not open to debate, however, is the issue of the loss of manganese due to soil depletion. An unfortunate by-product of modern agricultural technology, mineral impoverishment of farmlands must be considered as foods grown in soils with low levels of the silvery-grey essential nutrient may have their manganese content reduced.

Manganese is absorbed into the blood through the small intestine, so patients with a history of digestive distress may be at risk for manganese deficiency. Absorption of manganese may also be adversely affected by diets high in iron, magnesium, calcium, phosphorus and soy protein. Deficiencies of this important mineral may result in impaired growth, poor wound healing and other skin issues, as well as loss of hair color or reduced hair growth. Women with osteoporosis have been shown to have low levels of plasma manganese. And, it’s been known for almost 50 years that many epileptics are at risk for manganese deficiency.

Manganese functions as a critical co-factor for several vitamins. Under deficiency conditions, Vitamin C and some of the B-vitamins, including Vitamins B1, biotin and choline cannot be used efficiently. Manganese also has a function in the synthesis of fatty acids and cholesterol. And, several reports indicate involvement of manganese in the synthesis of steroid hormones such as estrogen, progesterone and testosterone. Manganese may also play an important role in the health of diabetics.

In their chapter in the highly regarded textbook, “Manganese in Health and Disease”, Doctors Baly, Walter, Jr., and Keen suggest a relationship between manganese and carbohydrate metabolism. One anecdotal report which they discuss involved the case of an insulin resistant diabetic patient who dramatically reduced his blood glucose levels from 350 mg/dl to 100 mg/dl by drinking manganese containing alfalfa tea. Further research showed that intravenous manganese chloride also lowered blood glucose levels rapidly.

Manganese functions as a structural constituent and activator of numerous enzyme systems, including those involved with energy production, protein metabolism and detoxification. And, its link to enzymes associated with lipid metabolism, are responsible for its aforementioned importance in helping the body maintain adequate levels of cholesterol and fatty acids and steroid hormones. Finally, manganese is an important actor in the production of enzymes involved in collagen synthesis and thus may have a part to play in anti-aging nutrition.

The best manganese-containing foods include liver and other organ meats. Pecans and almonds, brown rice, pineapples, and navy beans are good vegetarian sources of manganese and teas of all kinds are especially good beverage sources. Manganese is also available in supplemental fashion and most often found in combination with other nutrients in joint health and bone-building formulations.

History
The origin of the name manganese is complex. In ancient times, two black minerals from Magnesia (located within modern Greece) were both called magnes from their place of origin, but were thought to differ in gender. The male magnes attracted iron, and was the iron ore now known as lodestone or magnetite, and which probably gave us the term magnet. The female magnes ore did not attract iron, but was used to decolorize glass. This feminine magnes was later called magnesia, known now in modern times as pyrolusite or manganese dioxide. Neither this mineral nor elemental manganese is magnetic. In the 16th century, manganese dioxide was called manganesum (note the two Ns instead of one) by glassmakers, possibly as a corruption and concatenation of two words, since alchemists and glassmakers eventually had to differentiate a magnesia negra (the black ore) from magnesia alba (a white ore, also from Magnesia, also useful in glassmaking). Michele Mercati called magnesia negra manganesa, and finally the metal isolated from it became known as manganese (German: Mangan). The name magnesia eventually was then used to refer only to the white magnesia alba (magnesium oxide), which provided the name magnesium for the free element when it was isolated much later.

Zinc’s Powerful Hormone Balancing

By Ben Fuchs | Pharmacist Ben

We’ve discussed all the ways zinc and the lack of it can affect the body: skin health, bone, health and immunity are just some ways this essential nutrient can impact health. taking a daily 50mg dose of Zinc can prevent colds, eliminate acne and improve eczema. Zinc’s powerful hormone balancing properties can help improve prostate health and prevent male pattern baldness. All in all, for hundreds of different biochemical reactions, this stuff is amazing!

Zinc's Powerful Hormone BalancingThis is what I mean when I talk about the importance of nutrition supplementation. Think about the leverage here: one little pill with 50mg of Zinc in it (about the amount of zinc that would fit on the head of a pin) can control and stabilize and spark several hundred chemical processes in the body. Now that is some serious clout! And the most incredible part how little 50mg
of Zinc costs. What would you expect to pay for a (magic) pill that could keep hair on your head, cure your acne, strengthen your bones, build your immunity, enhance your digestion, strengthen your heart and make you think better?

And, with no down side when taken as directed. Would you expect to pay 100 dollars for a month supply? It would be worth it! In fact, for all those benefits, 100 dollars would be an incredible bargain. Well, surprise, surprise! A 30 day supply at a health food store will typically cost less than 5 bucks!

You can tell if you’re deficient in zinc by doing the “Zinc Taste Test”. You can use a solution of zinc sulfate and water (available online) or you can place a zinc sulfate tablet on your tongue. If you are not instantly repelled by a strong metallic taste chances are pretty good that you’re suffering from a lack of zinc.

The best way to get zinc is supplementally in the picolinate and monomethionine forms. These are available in most health food stores, but they are harder to find at drug stores where the typical forms available are zinc gluconate and zinc sulfate. The bioavailability of these cheaper zinc varieties is less than satisfactory and many people find that they can cause nausea or other digestive distress. A good daily dose is 50mg a day. Interestingly the signs of zinc deficiency (such as acne, hair loss, frequent colds and flues) can be duplicated by taking too much zinc (100mg a day or more). It’s also important to note than there is an antagonistic relationship between zinc and copper and it’s probably a good idea to take 2 mg of copper with every 50mg of zinc.

Look for chelate or glycinate forms of copper which are easily handled by the body. For those of you who want to try to obtain zinc through diet, in addition to the aforementioned oysters and the Rocky Mountain variety, the best sources include liver, lamb, venison, and seseme and pumpkin seeds. However, it should be noted than even the highest zinc concentration foods provide 10mg or so per serving.

SUMMARY:
– Zinc deficiency is relatively common.
– It’s important for hundreds of different biochemical systems to work effectively
– Deficiencies can show up in dozens of different ways including depressed immunity, bone problems, skin rashes and acne, digestive distress and hormone issues.

Phospho-lipid Phun!

By Ben Fuchs | Pharmacist Ben

Cell membranes are largely composed of fats (along with some proteins). There are two main types of cell membrane fats, cholesterol and phospholipids. We’ll discuss cholesterol in a later post. For this article we will be addressing phospho-lipids.

Phospho-lipids are interesting chemical structure with a watery end which contains the mineral phosphorus (phospho-) and a fatty end (-lipid). Phospho-lipids help cell membranes maintain their integrity and structure. They also conduct electrical energy which helps the membrane maintain its battery-like charge. This electrical activity is important for the health and function of the internal cell environment. Nutrients enter in the cell in part via pores and channels on the membrane. The openings dilate or constrict at least partially in response to phospho-lipid generated electrical energy. They have a voltage-sensing property which allows them to open and close pores on cellular demand.

Phospho-lipid
The electrical nature of phospho-lipids makes them especially important for brain and nerve cells (neurons), which are highly electrical in nature. Phospho-lipids are also important for skin health and play a particularly important role in maintaining skin softness and hydration.

Because phospho-lipids have a watery and fatty nature, they can help disperse dietary fats into digestive fluids. Bile is largely composed of phospholipids. The fats in cell membranes are protected from oxidation (rancidity) by phospho-lipids which bind the very active and oxidation-inducing metals iron and copper.

Because of the relationship of diseases to cell membrane health, taking advantage of phospho-lipid nutrition is an important step in the return to or the maintenance of health. While the body can make its own phospho-lipids, they do require the use of precious enzymes and energy so including them in the diet can be a helpful health strategy.

Also, if you have fat malabsorbtion, liver health issues or have had a gall bladder removed you may want to consider supplemental phospho-lipids to take advantage of their fat dispersing properties mentioned above. The same is true if you have neural problems such as Parkinson’s disease or cognitive issues such dementia, memory problems, or learning disorders. Up to 60% of the brain by weight is composed of phospho-lipids and similar compounds.

By far the best source of dietary phospho-lipids is eggs. Muscle and organ meats are good sources too as are wheat germ and peanuts. The fatty components of soy (not the protein) also contain phospho-lipids.

Supplemental phospho-lipids can also be obtained by using lecithin, either in its powder or liquid form. Taking 200 to 300 mg a day of choline and inostitol may also help improve the production of phospho-lipids.
