Vitamins that add zest to sex life

 Vitamins that add zest to sex life

 What we eat greatly affect our energy and behavior, thus people who eat proper food with the needed vitamins and minerals are more active, and they generally lead happier lives. They have lesser problems with health and sex. A healthy body has the energy and positive disposition to a zestful sex life.

Dr Abe V Rotor 




 Let us examine what these vitamins are and what specific roles they play in enhancing a healthy love life.
 Vegetables and fruits - key to a happy love life

Vitamin A. This vitamin helps in the production of sex hormones, and fights inflammation and infection of tissues. Acute deficiency may lead to atrophy of the testes and ovaries. Soft skin and healthy look may be attributed to a good supply of Vitamin A which comes from carrot, broccoli and other crucifers, yellow fruits and green leafy vegetables.

Vitamin B Family. This vitamin complex may be derived from unpolished rice, whole grains, nuts and seeds. Milk principally gives riboflavin, a type of Vitamin B2. Its deficiency may lead to the development of arthritis.

Niacin or Vitamin B3, on the other hand, is derived from asparagus, mungo sprouts, lean meat and fish. This vitamin improves memory, and together with Vitamin A and minerals, gives the flush and glow in the person. Its deficiency may result in skin eruptions and pellagra.

There is pyridoxine, which is vital to the functioning of our brain and nerves. Pyridoxine deficiency is manifested by a general feeling of weakness, neuritis, insomnia, irritability, and anemia. These lead to loss of sex appetite and failure of experiencing sex orgasm.
Most of the Vitamin B rich foods contain pyridoxine and pantothenic acid.

Pantothenic acid is classified as Vitamin B. It is needed in the production of body energy. Choline, which is allied to Vitamin B, enhances sexual arousal and performance. Choline is an ingredient of lecithin, a rejuvenator. Lecithin also contains inositol. Inositol, pantothenic acid, and para-amino benzoic acid (PABA) constitute what is termed as “youth vitamin." Sources of this vitamin other than those mentioned are eggs, crucifers like cabbage, liver, legumes, whole grain nuts and seeds like sesame.
These also provide another Vitamin B member, biotin, the lack of which could lead to depression, indigestion, slow healing of wounds, frequent colds and infections, shortness of breath. 

Most nutritious vegetable - malunggay (Moringa oleifera) 

Mango, avocado, citrus, tomato, guava, and strawberry are among the rich sources of Vitamin C. Doctors recommend a daily intake of 1000 milligrams although some people go as high as 2000 milligrams when exposed to toxins, infection and chronic illness. Taking Vitamin C is a practical way of preventing colds, and some people take it with two cloves (not heads) of raw garlic once they start feeling cold symptoms.

Vitamin D. Although there is no known direct effect on sex, the lack of this vitamin which is actually a hormone complex known as sterols, adversely affects calcium-phosphorus balance and metabolism. Bone deformity in children and osteoporosis are the chief manifestations of its deficiency.
 
 Regular outdoor exercise and sunlight exposure, and taking in of calcium-phosphorus rich foods protect us from deficiency disorders. Calcium supplement, mainly in milk, becomes a necessary part of the diet of older people. Aside from slowing down the aging process,

Vitamin E adds zest to sex life. It prevents the oxidation of fatty acids which are important in the production of sex hormones. It is found in most of the vitamin-rich foods, but some people may still need Vitamin E supplement often marked tocopherols [Greek: to bring childbirth) (Jensen).
Another vitamin is Vitamin F, which is needed by the thyroid, adrenal and prostate glands. It promotes calcium absorption, buffers cholesterol, helps keep our hair and skin look healthy. Most of the vitamin-rich foods provide us with adequate Vitamin F.

Pokpoklo (Codium edule) green seaweed is rich in iodine and vitamin B12 

It is important to keep always in mind that good health is the key to sexual vitality. Although it is highly recommended that we eat a lot of vegetables and fruits, particularly those specifically mentioned, it does not mean that the more we take them the more we are benefited by their nutrients and herbal values.

First, it is wise to think of certain herbs of their specific significance and the kind of illness we may be treating. There are herbs that are actually dilute forms of natural drugs, and not foods and dietary supplements.

Second is that anything taken in excess is bad. It is but proper to take these herbs with moderation, and better still, with proper consultation.

And third, avoid smoking. Smoking reduces life span to as much as 20 per cent, not considering the predisposition to smoking-related illnesses, principally lung cancer and heart attack, which may cut short a good life even before reaching middle age. Drugs, nicotine, caffeine, alcohol and menthol are known to deaden the nerves in the long run. Medical reports point to them as culprits to many kinds of potency problems both in men and women.

Another form of Vitamin B is folic acid, another form of the B vitamin folate which helps eliminate homocysteine from the blood, an amino acid linked to arterial disease and heart attack. It is also essential in embryonic development and early growth. That is why folic acid is added to milk and foods as protection against birth and childhood defects.

People who eat a lot of dark leafy vegetables, carrots, beans, asparagus, and whole grain, need not worry about folic acid deficiency.

Vitamin B6, which is derived from ginger and certain vegetables, brings relief to the so-called carpal tunnel syndrome (CTS, which is a painful and irritating condition developed by long hours at the keyboard. Carpal tunnel syndrome is characterized by swollen tendons that move the fingers. Other than this remedy, proper posture and work habits must be followed. Ginger as anti-inflammatory properties, aside from its value in toning the cardiovascular system and r educing platelet aggregation, thus helping in protecting heart attacks and strokes.

The most complex of all vitamins is Vitamin B12 or cobalamine. It is important in the synthesis of nucleic acid and myelin, the covering of nerves. Vitamin B12 was discovered in papait, derived from the chyme of ruminant animals. The chyme is heated and pasteurized (heated below boiling for a few minutes and filtered). It is then mixed with kilawen (medium rare goat’s meat or beef). This preparation is effective against tuberculosis and anemia. 

Vegetarians are at risk for its deficiency, especially among children, which may result in pernicious anemia characterized by symptoms of weakness, apathy, light headedness, shortness of breath, numbness of extremities, and loss of balance. Among older people acute Vitamin B12 deficiency may lead to loss of memory and disorientation.

Other food sources of this vitamin are fish and poultry, seaweeds like gamet (Porphyra), arusip (Caulerpa), and gulaman (Gracillaria). Chlorella, a green alga and Spirulina, a blue-green alga, contain high Vitamin B12. Lack of Vitamin B12 is manifested by fatigue, irritability, paleness, muscle jerking, and mild mental problems, all of which can greatly adverse sexual life.

Vitamin C (ascorbic acid). Prolonged lack of this vitamin may lead to scurvy. Poor sex life is attributed to its deficiency. Its role is in the absorption of iron. Iron aids in oxygenation of the blood. A well-oxygenated blood is efficient in carrying oxygen, hormones and nutrients to the organs and tissues of the body. How do we know if we lack this vitamin?  It is manifested by the bleeding of gums.  

It is important to consider that we have to maximize the vitamins present in the food we eat. We must remember that heat destroys vitamins and other nutrients, for which reason, vegetables must not be overcooked.

It is also well to know that alcohol, nicotine, drugs and coffee prevent the absorption of nutrients, principally vitamins and minerals. This may develop into a kind of malnutrition that may be taken for granted. Thus, people who abuse themselves with these substances suffer poor health and generally lead sedentary lives.

It is also good to remember that even if we get the proper kind and amount of food, we must complement it with regular exercise and good rest, a positive disposition notwithstanding.

And lastly, both physical and mental well-being are important to healthy sex. Many experts say that the greatest aphrodisiac is the human mind.

Crocodile in the Sky

Crocodile in the Sky
Dr Abe V Rotor

These two photographs of Manila Bay along Roxas Boulevard
were taken from the Cultural Center of the Philippines where
the 2009 Ramon Magsaysay Awards Ceremonies was held on
that day, August 30, 2009.


Crocodile in the Sky

I thought I would see the last of your kind
With every tree cut, swamp drained,
The river dammed or made into sewer,
The shore into resort and fishpond.
Or at least in homage, I would visit you
In a museum, stuffed or in skeleton.

Darwin and Freud studied you well
Didn’t they? So with Orwell and Marx,
Prophets and sages of old and new,
Crick and Watson, Venter and Collins –
If your DNA doesn’t suffice to tell me
All about you – then who are you?

You must be a ghost who haunts and lurks,
Immortal before your mortal demise
And haunting man since his fall,
And haunting him still - perhaps forever;
Ah, you are the biblical devil no less
To test man's rationality and obedience.

You have no place then except the place
Of your birth and those of your ancestors
In flesh and blood – and if you are a ghost,
It’s time to say goodbye to your friends,
Your guardians, benefactors,
And clear your image in the sky. ~

Energy from Plants. Can we harness energy directly from plants, rather than harvest energy from their products?

Can we harness energy directly from plants, rather than harvest 
 energy from their products?

Can we harness energy from plants, rather than harvest energy from their products?

As a simple review, only plants - green plants (those containing chlorophyll which include algae and relatives) - have the ability to capture solar energy and convert it into chemical energy. That is, the light of the sun into sugar (calories), by means of photosynthesis.

Sugar (CHO) is either transformed into energy for the use of the plant itself, or transferred to animals that feed on the plant.

Otherwise this primary product is stored into complex sugar like starch, oil, and more importantly protein (CHON) which is used as "building blocks" in growth and development. Post-photosynthetic processes are specific in the production of resin, gum, cork, wood, and many other organic compounds, which when taken by animals are converted into energy, and compounds needed in their growth and development. Otherwise the unused materials remain at store, or may be lost through oxidation, biological (e.g. fermentation), and physical means (e.g. burning).

Energy is a continuous, incessant flow in the living system, moving in and out in the process. Biologists explain it in terms of metabolism (catabolism or energy-gain, and anabolism or energy loss or respiration), whereas ecologists draw the lines of interrelationships of participating organisms as food chains forming food webs, and food pyramid to indicate hierarchy in energy utilization. 

  Intricate network in a leaf through which energy and materials flow.

But as a basic principle plants are autotrophs (photosynthesizers), while animals are heterotrophs (consumers in hierarchical order, with man being the ultimate consumer in most cases).

With this in mind, how can we the harness solar energy in the plant during photosynthesis?

How can we create a short circuit in directing the electrons before they are used in the final stage of photosynthesis - and instead, convert it directly into electricity?

We can - theoretically - if we can only develop a method to “interrupt” photosynthesis and redirect the electrons before they are used up to make sugars. So instead of harvesting sugarcane, and make alcohol, and burn it to produce light and heat – or electricity - we might as well invent a living solar panel and directly "harvest" electricity for our domestic and industrial needs.

Sounds futuristic, isn’t? Well, it is. But remember, no one believed in splitting the atom a century ago and produce nuclear energy. There are now hundreds of nuclear plants all over the world, producing electricity to as much as 50 percent of a country’s electricity need. Such is the case of France, Germany and Japan.

How about hydrogen fuel? There are cars - thousands of them running on Hydrogen fuel. And the byproduct is not smoke that add to pollution. It is H2O or water.

Now, hear this. During photosynthesis, the photons that are captured by the plant are used to split water molecules into the component parts of Oxygen and Hydrogen. By doing so, they produce electrons. The electrons are then utilized by the plant to create sugars that are then used by the plant (and the animals that eat it) for growth and reproduction.

Architecturally the leaf is like a battery.

"The technology involves separating out structures in the plant cell called thylakoids, which are responsible for capturing and storing energy from sunlight. Researchers manipulate the proteins contained in the thylakoids, interrupting the pathway along which electrons flow.

These modified thylakoids are then immobilized on a specially designed backing of carbon nanotubes, cylindrical structures that are nearly 50,000 times finer than a human hair. The nanotubes act as an electrical conductor, capturing the electrons from the plant material and sending them along a wire." 
(Reference: Ramaraja Ramasamy, assistant professor in the University of Georgia and the author of a paper published in the Journal of Energy and Environmental Science.)

Tree-planting project, Mt Makiling, Laguna

This research is important, because photosynthetic plants function at nearly 100% quantum efficiency. Almost every photon of sunlight captured by the plant is converted into an electron. And what do we get in our solar cells today? A measly fraction - 12 to 17 percent. This huge difference propels us to research towards this direction, away from fossil fuels, and even from the circuitous biomass fuel generation

Harvesting electricity directly from plants may be weird and wild an idea as in Jules Verne fiction novels. But now we can go Around the World in Eighty Days - and even reach the moon and explore outer space. We can now go deeper than Twenty Thousand Leagues Under the Sea and even reach the ocean floor.

And how about coming up a perpetual machine, elusive dream child of science?
The answer may lie in Plant-Based Energy Generation. ~

Phosphorescent Caterpillars

Phosphorescent Caterpillars

Dr Abe V Rotor
Caterpillars eating the leaves of ilang-ilang (Cananga odorata), 
at home near La Mesa watershed.

They came - an army of hungry glowing worms,
on a sunset on a tall ilang-ilang tree;
there they hang like lanterns or neon far away,
and in crepuscular light there I could see
a familiar tree traced by its essence in the air,
and now by the phosphorescence from this tree -
Christmas ahead and beyond yet here at hand,
by the glow of these worms reminds me of Thee;
through nature's ways to guard the frail and lowly
through the secret of ephemeral beauty. ~

NOTE:  Some photos shown here were not really edited.  There are cameras, cellphones, and computer programs that automatically correct certain deficiencies of images.  Too much editing diminishes, if not destroy, authenticity of images.  Thus the adage, "You and I may lie but the camera doesn't lie." leaves room of doubt with modern photography.  By the way, photography has not earned its place as a bona fide form of art along painting, sculpture, architecture, or the so called visual arts.
