Getting Back to the Basics of Green

Hippocrates Health Institute Sprouts

Presently we are in midst of a global green trend. Everywhere we hear the mantra, be green, eat green, live green, etc. While it might seems like something new to many people, in essence “green” simply means living naturally. At Hippocrates Health Institute “green” encompasses true super foods from a multitude of natural sources: from the ground there is vegetation, sea vegetables abundantly found in the oceans, and in fresh water in the form of algae. In sourcing optimum nutrition Hippocrates Health Institute embraces the consumption of wheatgrass juice, sunflower and pea sprouts and juice, sprouts, dark leafy greens, algae, and seaweed, much of which is organically grown, locally on Hippocrates’ 50-acre campus.

Humans as mammals are designed by nature to consume vegetables. As mammals go, the majority consumes a raw diet of grasses and leafy greens. Humans are the only mammal that cooks its food and one of only a few mammals that eat other animals. The most common defense to eating meat is for its protein content. In truth the best quality proteins to sustain health comes from the vegetable kingdom in the form of sprouted beans and seeds, nuts, algae, grains and grass (wheatgrass juice), which we encourage at Hippocrates Health Institute as part of our wellness program. In fact approximately 85% of mammals consume only greens, and they tend to be the largest and strongest in the animal kingdom, and where do they get their protein? Plants!

Hippocrates Health Institute first discovered the power of greens, in particular grass 50 years ago when its founder Ann Wigmore was searching for a means to overcome a chronic illness. Ms. Wigmore observed how Cows obtained all their muscle, strength and power solely from grass. Ann returned to perfect health after some weeks of chewing on grass and spitting out the fibers. She began to experiment on different types of grasses and found that wheatgrass while providing optimal nutrition also tasted the most palatable.

Hippocrates Health Institute Wheatgrass

Wheatgrass at Hippocrates Health Institute

Since its founding over 50 years ago Hippocrates Health Institute has learned a great deal of information into the healthful properties of wheatgrass and raw vegetables. Chlorophyll, which is abundant in all dark leafy greens, increases the body’s blood quality allowing more uptake of oxygen into the cells, and since plants also contain large quantities of oxygen, we can absorb it more effectively and in greater quantity. Nowadays with oxygen levels becoming less in the air we breathe, especially in cities (where most of the worlds’ populations live), we all need to find ways to increase oxygen levels and oxygen quality. Oxygen plays an important role in our cells, reducing the risk of cancers and virus infection.

As part of our Life Transformation Program at Hippocrates Health Institute we encourage the consumption of wheatgrass juice, green sprouts, and green juices that promotes ones body to self-regulate its state of wellness. Complementary to these super foods Hippocrates also supports internal cleansing (detoxing and alkalizing) and exercise. Hippocrates Health Institute promotes a lifestyle where the foundation of your diet consists of plants. Green plants first receive energy from the sun giving them life, and when we consume these living foods we benefit from this ‘living vibrational energy’ together with pure oxygen. Our cells are literally craving for clean oxygen, so go ahead and treat yourself to leafy greens, wheatgrass and sprouts today! You can simply start by growing your own at home, it’s that easy! Learn to listen to your heart, as it contains more answers than your head. Love deeply and love yourself, and remember – it’s all about the greens!

Hippocrates Health Institute Developing The Most Advanced Enzymes

Over 90 years ago Dr. Edward Howell, physician and researcher discovered the secret to how our bodies digest with the aid of enzymes supplements. The Hippocrates Health Institute has always recognized and supported Dr. Howell’s theories on the use of digestive enzymes, and over the past 60 years, have integrated this knowledge into the Hippocrates’ dietary program. Hippocrates Health Institute has always believed this to be an important field to conduct further research and development to improve enzyme supplements.

Hippocrates Health Institute director Brian Clement together with Victoras Kulvinskas began research in 1993 on ways to improve the efficiency of how enzyme supplements enter blood cells. They discovered after two years of research how to combine measured quantities of fresh-water algae, salt-water algae, kamut grass and herbs with a spectrum of enzymes so that blood cell absorption increased.

Since the digestive processes of the body eventually end up at a cellular level, with the cells deciding what nutrients are needed, the Hippocrates researchers found that introducing their new formula actually made the cells more receptive to nutrient uptake.

In the years following this important discovery, intense research and development at Hippocrates Digestive EnzymesHealth Institute has resulted in the most advanced and effective digestive enzymes ever created. Hippocrates has developed this formula into a veggie capsule product called LifeGive HHI-Zyme and forms part of its extensive LifeGive supplement range.

The Hippocrates Health Institute’s LifeGive HHI-Zyme helps to increase cellular enzyme absorption thereby assisting to combat oxidative stress, improve circulation, support muscle and joint recovery after exercise, as well as providing other systemic benefits.

Enzymes – The Secret Fountain of Youth

Enzymes are large protein molecules found in all living things – plant and animal. Your body is capable of producing two types of enzymes, metabolic and digestive. Digestive enzymes include things like protease, and lipase, and amylase for the digestion of proteins, carbohydrates and fats. In human physiological terms, metabolic enzymes are the spark of life. They are the catalyst for every single chemical reaction in your body – every process, every action, every muscle movement, every sense, every thought, every word and every deed. The more enzymes you have inside of you the more alive you become.

Food in its’ original, fresh, ripe, raw and unadulterated state contains naturally occurring enzymes which aid in its’ own digestion. When a peach falls to the ground the cell walls are broken and a bruise develops at the point of contact. The enzymes are liberated and the peach begins to digest itself. The same process occurs when we chew the peach. Thisistock_000048071644_large greatly reduces the burden of digestion from your body since it does not have to go through the taxing process of manufacturing enzymes for the digestion of the peach.

This is a key point as the body expends a great deal of energy in the digestion of food. When you eat a cooked food meal, 80% of your body’s total available energy is expended in the processing of that meal. When you eat a raw food meal the energy expended in processing is reduced to only 20%. The less energy you expend on digestion the more energy you have available for life. Most people go through their entire lives totally unaware of their true potential because their bodies are perpetually under the heavy burden of processing the unnatural foods they are eating.

The more food is processed the more enzymes are destroyed and it becomes mostly “dead.” Because of their highly perishable nature, heat processing (cooking) destroys 100% of the enzymes in foods rendering it completely inert. This increases shelf life which is very desirable for the commercial food distribution industry but, it is highly undesirable for your body’s health and well-being. As a result of cooking and other forms of food processing, enzymes are largely missing from the Standard American Diet (SAD.) Other Fresh green vegetablesessential nutrients such as vitamins, minerals and proteins are also destroyed in the processing of food which creates other issues with your health which we will explore in greater detail in another article.

However, all is not lost as the body has the capability of producing digestive enzymes to make up for the lack of enzymes in cooked and otherwise processed foods. The problem is that you were born with a finite ability to manufacture enzymes. When you deplete your enzyme manufacturing capability, you die. The less of a burden you put on your body to produce digestive enzymes, the more metabolic enzymes will be available throughout your lifespan. This greatly improves your energy, vitality, health and longevity.

This is part of the magic and life force energy living foods like sprouts. According to Dr. Edward Howell who literally wrote the book on enzymes called “Enzyme Nutrition”, sprouts have up to 100 times the enzymes of even raw diet! Living foods are alive and you are alive. Since life begets life, the more living foods you take into your body at the expense of dead foods the more alive you become! It is not uncommon to see people who eat raw and living foods to look 15 years younger than their true chronological age and have soaring energy levels. Raw and living foods are truly Anti aging Living foods create living bodies. Dead foods create sick, decaying and dead bodies.

Rebounding for Lymph Health

The lymphatic fluid is a clear liquid that contains the body’s T- and B-cells. The lymphatic system, as Dr. Morton Walker refers to it in his book Jumping for Health, is the “metabolic garbage can of the body. It rids you of toxins, such as dead and cancerous cells, nitrogenous wastes, fat, istock_000008593117_largeinfectious viruses, heavy metals, and other material cast off by the cells.” CJ Puotinen outlined how modern living and clothing, such as bras, and lack of exercise lead to constriction of the lymph system or allow it to lag and become clogged. (“Lymphatic Immune Support,” May/June and July/August 2000 issues of Well Being Journal.)

When you rebound, you are helping your cells metabolize, cleanse and renew, and you are helping your lymph system to pump and drain out the body’s waste. Unlike the cardiovascular system, with the heart as a pump, the lymph system does not have a pump. Lymph is moved like a hydraulic pressure system…. The lymph tubes a…re filled with one-way valves that only open up, or allow drainage toward the center of the body. When pressure below the valve is greater than above ( moving downward on the rebounder) the valves are forced open so the fluid can flow.” There are only three ways foristock_000011270803_large the lymph system to “pump” and cleanse: exercise, which helps muscular contraction; massage of the tissues it serves to get it to pump back into the pulmonary circulation; and gravitational pressure with its resultant internal massage.

Rebounding provides all three ways of removing waste from the cells. Dr. Walker sums it up: “Then arterial blood enters the capillaries in order to furnish the cells with fresh tissue fluid containing food and oxygen. The bouncing motion effectively moves and recycles the lymph and the entire blood supply through the circulatory system many times during the course of the rebounding session.” And the joy of it all is that you don’t even have to exert yourself to get these benefits. The eldest of the elderly can do this, as well as the handicapped person, and the arthritic.

​​​​Sprout Into the New Year

As 2014 draws to a close and 2015 is almost upon us it is a perfect time to make a healthier resolution for the New Year. A simple and very effective healthy practice is to resolve to add a small amount sprouts to every meal. Every grocery store will have at least one type of sprout on the shelf or you can grow your own! You can sprinkle a few on your salad, add to your entree or have them anytime as a healthy snack.Sprout-1

Sprouts are baby plants in their prime and are, on average 20 times more nutritious than even the best raw vegetables. At this early stage of growth sprouts have a greater concentration of nutrients than at any other time in the plant’s life. All of the energy stored in the seed is ignited by the soaking and rinsing process.

Sprouts are the perfect food because they can be grown anywhere in the world anytime of the year right in your own kitchen. The easiest sprout to grow is mung beans. All you need is a one quart wide mouth Mason jar, a sprouting lid, the seeds, and water. Here are the steps:

1. Put ½ cup of mung beans in the jar and install the sprout lid.
2. Fill the jar with at least two cups of water and soak at room temperature for eight hours.
3. Drain the water and leave the jar upside down in a drain pan propped at a 45 degree angle to allow the water to drain.
4. Rinse twice a day for two or three days.
5. Harvest when the roots emerging from the beans and are at least as long as the bean itself.
6. What you are not going to use right away can be stored in the refrigerator for a few days. I suggest storing sprouted beans and legumes in a green bag with the air removed. If moisture is present, placing a paper towel in the bag will extend shelf life.

Bean sprouts: An excellent source of energy

In today’s busy world, the health-conscious are increasingly looking at easy ways to keep healthy. However, in this quest for quick fixes, we often lose sight of simple ways to keep healthy by consuming simple foods, such as through a raw diet. Living foods such as bean sprouts are an excellent source of energy, require little effort to produce, and are an excellent way to kick start any raw diet.

Bean sprouts were first cultivated in the Far East, and still find their place in many Asian cuisines today. Popular in China, Japan and southeast Asia, bean sprouts are great stir fry Bean sprouts (1)ingredients, but can also be eaten raw.

The health benefits of bean sprouts are numerous, but the most beneficial effects for an otherwise healthy individual is that they are a great source of energy. Consuming bean sprouts can dispel feelings of malaise, and are a great way to ‘pep up’ after a long day. In addition, bean sprouts can also help prevent a number of cancers, such as breast cancer, and can be helpful for men with prostate problems and other glandular disorders. Men with premature balding may also derive benefits from bean sprouts, as can those experiencing gray hairs.

It is easy to produce your own bean sprouts from the comfort of your own home. First, Bean sprouts (2)soak half a cup of seeds in warm water for eight hours, or overnight. Drain the water and then rinse with warm water. Next, leave the sprouts to grow with an eight-pound weight on top for approximately five days, ensuring that you rinse them twice daily throughout. Following this process for just half a cup of seeds can yield up to five cups of bean sprouts, meaning that one does not have to complete this process often to gain the benefits of bean sprout consumption.

Sprouts – A complete diet for effective health care

Many people today are trying to improve their health by eating a diet that includes more nutrition, raw foods. Over processed, over cooked, over preserved foods have left many people around the world overweight and unhealthy. Let’s take a look at a simple and delicious food that is highly nutritious and can help you get started on putting delicious, raw foods in your diet.

Foods sustain life but all types of foods are not good for health. Even foods that are healthy can be dangerous for health if consumed in conditions not recommended by health experts. Any type of food must be consumed only in the recommended amount and fMultiSproutsorm. The properties of a healthy food can change for worse when it is processed into a form that is not healthy. Processed foods are considered unhealthy because such food contains synthetic chemical ingredients. These chemicals are used to make processed foods more appetizing, last longer and look better. Because of various health issues associated with commercially produced foods, more and more people are switching to healthier food options. One of the best options in this category is raw foods that retain all natural nutrients.

Sprouts as raw foods are rich in essential nutrients like vitamins and minerals. Such foods contain minerals like calcium, potassium, magnesium, phosphorous and iron. Sprouted seeds, grains and legumes already have dietary fiber, omega-3 fatty acids and foliate. Studies have shown that the level of essential nutrients increases many times after these foods are sprouted. If you think only chicken, meat, eggs, fish and dairy sprouts1products contain protein then here is a surprise. Sprouts are high in protein that can be as high as 35 percent. You can obtain a large part of your body’s protein requirements from the sprouts.

Vegetarians and people who prefer raw foods really love sprouts. The high fiber content means sprouts are easy to digest. Individuals suffering from digestive problems can benefit from this type of foods. If you are trying to lose weight then sprouts must be part of your weight loss plan. Foods in this category contain more enzymes, minerals and vitamins compared to most vegetables and fruits. The nutritional value of protein present in the seeds and grains changes for better during the sprouting process. Whether you want to moong Sprouts lead a healthy life, reduce your weight, avoid health issues or recover from an illness, sprouts can be your best foods.

The high nutrition value and positive health effects make sprouts highly suitable for people leading a vegan lifestyle. You do not need any high level of skill to grow sprouts. It can be done by anyone without spending any extra money and without using any special tool or technique. Include sprouts in your daily diet if you want to lead a healthy lifestyle.

Herbs for Happier Emotions and Brighter Brains

People who detox physically also detox emotionally. This connection is often seen among the guests at Hippocrates Health Institute while going through the Life Change Program. While the unpleasant aspects of physical detox are well known, the emotional side of detox is often overlooked. This is why Hippocrates guests are given a stress assessment and a consequent stress management support session. These sessions help most guests better deal with their emotional detox. However, there are some individuals who choose to come to the program hoping to balance their emotional challenges without having to take medications. Those individuals often find their way to relief through the nutritional and counseling help available in the program. The use of herbs and other alternative therapies are also found to be helpful by some. It should be emphasized that this program is by no means a substitute for psychiatric treatments if one needs psychiatric help.

Herbs have been long used to help promote healthy memory and neurological function. Many studies have been conducted in Europe and the US on the effects of natural supplements on the brain. The results have been promising. Dandelion leaves, for herbs-1example, provide vitamins A and C, and its flowers are one of the best sources of lecithin, a nutrient that elevates the brain’s acetylcholine and may play a role in preventing Alzheimer’s disease.

Furthermore, the right balance of nutrients is important for protecting and promoting healthy brain cell function. Another critical aspect is to protect the arteries supplying oxygen and nutrients to the brain. The phytochemicals unique to the Ginkgo Biloba tree restore better blood flow to the brain, allowing improved use of oxygen, and protect the cells from free radicals.

Let the blues flush away:

Sadness and grief often dominate the emotional life of many guests at Hippocrates Health Institute because they have been dealing with major health challenges. Hopelessness often accompanies such feelings. As a result, many individuals experience symptoms which go along with depression. Many of these symptoms are dealt with through the psychological support available in the Life Change Program. Often our guests choose to deal with these problems using herbs. Some of the herbs which are often helpful in combating the emotional symptoms of depression are described below. It is important to note that it is suggested for individuals going through these symptoms to use herbs under the supervision of a Naturopathic Physician or nutritionist, such as the ones at Hippocrates Health Institute.

Lemon balm (Melissa officinalis):

A safe and non-habit forming herb often used for nervousness, depression, insomnia, and nervous headaches. The volatile oils in the plant (particularly citronellal) have a sedative effect even in minute concentrations, so use with caution.

Ginseng (Panax ginseng and Panax quinquefolius): An adaptogenic herb often used to boost mood, improve memory and attention, lengthen physical and mental endurance, improve test scores, and ease anxiety.

Siberian Ginseng (Eleutherococcus senticosus): An adaptogenic herb often used to boost kind-of-herbsconcentration and focus without the letdown that comes from stimulants like caffeine.

Gotu Kola (Centella asiatica): An herb often used to improve memory, concentration, and mental performance levels.

Yerba maté (Ilex paraguariensis): A shrub that may have the effect of stimulating the mind, increasing concentration, and easing depressive moods.

St. John’s Wort (Hypericum perforatum): An herb often used in the treatment of mild to moderate depression. Not recommend as a first line or solo treatment for depression; may be effective for a patient with a history of positive response to low-dose SSRI medications.

Golden Root, Arctic Root, or Roseroot (Rhodiola rosea): An herb often used to improve mental and physical energy, cognitive functions, memory, and performance under stress. By providing extra mental energy, this herb has helped some overcome sad feelings and other symptoms of depression. Omega-3 Fatty Acids and proper forms of B-12 are known to improve the functioning of neural tracks which help regulate mood, and thus may also be effective in combating depression.

Worriers become calmer:

Every major health challenge involves fear and anxiety. Many of the Hippocrates Health Institute guests suffer from stress, worry and fear when they come to the program, especially if their family members or conventional health practitioners have discouraged them from seeking non-conventional healing modalities.The guests often learn to cope with the symptoms of worry and fear through stress management, meditation, guided imagery, Qigong, Tai Chi, breathing techniques, bio-identical hormone therapy, etc.

The following herbal remedies are also known to help such conditions.

LifeGive™ AdrenaSupport™ is a nutrient-rich supplement that strengthens the adrenal gland. In combination with LifeGive™ Kind Kidney,™ this helps rid you of worry by stabilizing hormone action in the anatomical region.

Oat straw: A soothing herb often used as a tea for cases of mild to moderate anxiety. May also be effective to combine with other nourishing herbs like Chamomile (Matricaria recutita) and Linden.

Passionflower (Passiflora): A flowering plant with mild narcotic properties that help promote sleep. This strong calming herb may occasionally be found useful for severe daytime anxiety. Passionflower can be brewed into teas, made into tinctures, or encapsulated.

Kava (Piper methysticum): A sedative that is primarily used to help one relax without disrupting mental clarity. May also be helpful to reduce anxiety.

Valerian (Valeriana officinalis): An herb often used for its sedative effects.

Ginkgo (Ginkgo biloba): An herb that is often used to improve memory and concentration.

Omega-3 Fatty Acids may also be helpful to deal with challenges of stress, worry and fear. Hippocrates Health Institute supports nutritional treatment by suggesting foods rich in Omega-3 Fatty Acids, including sprouted seeds.

Boosting the brain:

Cognitive challenges often noticed at Hippocrates Health Institute are related to what many guests call, “brain fog.” Some major diagnoses affect the brain function. Lyme herbs11disease, for example, is known to cause cognitive decline and memory impairment. Those with Chronic Fatigue Syndrome express similar symptoms as well. The Hippocrates Health Institute diet includes many nutrients to particularly boost brain function. Some of the herbs known to help the same function are mentioned below.

These herbs may be ideal to combat certain cognitive challenges, but should be used under the supervision of a physician.

Arctic Root: See “Golden Root” above Five Flavor Berry (Schizandra chinensis): A Chinese herb known to boost concentration.

Ginseng (Asian Ginseng, Oriental Ginseng, or Siberian Ginseng): An herb known to help resist stress and to boost energy.

 Maca (Lipidium meynii): An herb used for thousands of years by Andean people to improve energy, sexual activity, stress tolerance, etc.

Ginkgo (Ginkgo biloba): An herb used often for improving cognitive and memory challenges in Chinese medicine.

Brahmi (Bacopa monniera): An Ayurvedic herb used by Indians for thousands of years to enhance stress resilience, reduce anxiety, and improve cognitive function.

Aromatherapy:

Using aromatherapy may also be a positive and effective method of using herbs to combat the emotional symptoms of detox. Essential oils may be diffused to smell their aroma, and in some cases be applied topically, usually with a carrier oil, such as grape seed, almond,herbs or avocado oil. The following herbs are especially helpful as essential oils for concentration:

Rosemary (Rosmarinus officinalis): Referred to as “the herb of remembrance,” Rosemary is the best known aromatherapy treatment for poor memory, difficulty concentrating, fatigue, and improving mental clarity.

Peppermint (Mentha x piperita): Cooling and refreshing, Peppermint essential oil energizes the mind and mood, improving mental clarity and memory.

Basil (Ocimum basilicum): Oil of Basil is perhaps the best aromatic nerve tonic. It is often used to clear the head, relieve intellectual fatigue, and give the mind strength and clarity.

In Conclusion:

Western medicine draws an unnatural line between emotions and physical illness, when no such line exists in the body and mind. Regaining ones balance from the experience of anxiety and nervousness, stress and tension, panic attacks, PMS, ADD, depression, and so forth, may be successfully approached with the use of herbs under the supervision of a physician. From treating insomnia, anxiety, and mild depression, some of the favorite herbs used at Hippocrates Health Institute are Peppermint, Chamomile, and Lavender. The most common treatments using herbs are herbal teas and tinctures, as well as essential oils used in aromatherapy.
