Your Cardiovascular
System
The heart, blood vessels, and blood comprise your cardiovascular
system. Blood (shown in red) moving from heart delivers oxygen and
nutrients to every part of the body. On the return trip, the blood (shown
in blue) picks up waste products so that your body can get rid of them.
Your heart is a muscle about the size of a clenched fist.
It contracts and relaxes about 70 times a minute at rest (more if you are
exercising), beats about 30,000,000 times a year, and pumps about 4,000 gallons
of blood daily through its chambers to all parts of the body. Your blood
travels through a rubbery collection of big and small vessels. If strung
together end to end, they can stretch 60,000 miles (enough to circle the globe 2
1/2 times)!
As you inhale, air is sent down to your lungs. Blood is
pumped from the heart through the pulmonary artery to your lungs where carbon
dioxide is removed from it and oxygen is mixed in with it. The oxygenated
blood is carried back to the heart through the pulmonary vein. The
arteries carry blood away from your heart under high pressure to smaller and
smaller branched tubes called capillaries. This delivers oxygen to all the
cells in your body including bones, skin, and all organs. Veins bring
oxygen-depleted blood back to the heart.
Your blood is mostly comprised of a colorless liquid called plasma.
Red blood cells (which give blood its red appearance) deliver oxygen to cells
and carry back waste gases in exchange. White blood cells attack and kill
germs and Platelets cells help your body repair itself after injury.
Your cardiovascular system is a beautiful symphony which sustains
your life. Often it is taken for granted and little is done to ensure its
long-term performance. Lack of preventive care will transform your
cardiovascular system into a time bomb.
Cardiovascular
Disorders
In 2004, cardiovascular diseases claimed 869,724 lives in the United States (36.3% of all deaths). 148,000 lives belonged to Americans under 65. According to 2005 estimates from the American Heart Association, 80,700,000 people in the United States have one or more forms of cardiovascular disease:
In 2004, cardiovascular diseases claimed 869,724 lives in the United States (36.3% of all deaths). 148,000 lives belonged to Americans under 65. According to 2005 estimates from the American Heart Association, 80,700,000 people in the United States have one or more forms of cardiovascular disease:
1) High Blood
Pressure - 73,000,000
-
High blood pressure puts added force against the artery walls which overtime damages the arteries making them more vulnerable to the narrowing and plaque build up associated with atherosclerosis.
2) Coronary Heart
Disease (caused by atherosclerosis, the narrowing of the coronary arteries due
to fatty buildups of plaque which blocks the flow of blood to heart muscle
thus depriving the heart of oxygen. It is likely to cause Chest Pain and / or
Heart Attack) - 16,000,000
-
Myocardial Infraction (acute heart attack occurs when a clot or spasm blocks an already narrowed coronary artery, restricting oxygen to a portion of heart muscle resulting in permanent injury) - 8,100,000
-
Angina Pectoris (chest pain or discomfort caused by reduced blood supply to the heart muscle) - 9,100,000
An estimated
1,200,000 Americans will have a new or recurrent coronary attack this year, and
about 310,000 will die as a result.
3) Stroke (occurs
when a blood vessel in the brain is blocked or bursts) - 5,800,000
-
Without blood and the oxygen it carries, part of the brain starts to die and the part of the body controlled by the damaged area of the brain won't work properly.
-
Brain damage can begin within minutes of a stroke.
4) Heart Failure
(the heart does not pump as well as it should) - 5,300,000
-
About 550,000 people are diagnosed with heart failure each year.
-
It is the leading cause of hospitalization in people older than 65.
5) Arrhythmia
(Abnormal Heart Rhythm) - more than 850,000 Americans are hospitalized for an
Arrhythmia each year. It is caused by many factors including:
-
Coronary Heart Disease
-
Electrolyte imbalance in your blood (such as sodium or potassium)
-
Changes in your heart muscle
-
Injury from a heart attack
-
Healing process after heart surgery
6) Aortic Aneurysm
(bulge in a section of the aorta which can burst causing serious bleeding which
can lead to death within minutes) - approximately 176,000 Americans are affected
annually leading to 15,000 deaths per year.
-
Medical problems such as high blood pressure and atherosclerosis weakening artery walls as well as wear and tear that occurs with aging can result in outward bulging of the aortic wall.
-
The slower flow of blood in the bulging area can cause clots to form. If a blood clots breaks off in the chest area, it can travel to the brain and cause a stroke. If blood clots break off in the belly area, they can block blood flow to the belly or legs.
Risk Factors
As of 2006, 51% of men and 40% of women at age 50 in the United States will develop cardiovascular disease during their lifetime. The primary determinants of risk are:
As of 2006, 51% of men and 40% of women at age 50 in the United States will develop cardiovascular disease during their lifetime. The primary determinants of risk are:
- Smoking - Smokers' risk of developing coronary heart disease is 2–4 times that of nonsmokers. Cigarette smoking also acts with other risk factors to greatly increase the risk for coronary heart disease.
- High Cholesterol - As blood cholesterol rises, so does risk of coronary heart disease. When other risk factors (such as high blood pressure and tobacco smoke) are present, this risk increases even more. A person's cholesterol level is also affected by age, sex, heredity and diet.
- High Blood Pressure - High blood pressure increases the heart's workload, causing the heart to thicken and become stiffer. It also increases your risk of stroke, heart attack, kidney failure, and congestive heart failure. When high blood pressure exists with obesity, smoking, high blood cholesterol levels or diabetes, the risk of heart attack and stroke increases several times.
- Physical Inactivity - An inactive lifestyle is a risk factor for coronary heart disease. Regular, moderate-to-vigorous physical activity helps prevent heart and blood vessel disease. The more vigorous the activity, the greater your benefits. However, even moderate-intensity activities help if done regularly and long term. Physical activity can help control blood cholesterol, diabetes and obesity, as well as help lower blood pressure.
- Obesity / Excess Weight - People who have excess body fat (especially if a lot of it is on the waist) are more likely to develop heart disease and stroke even if they have no other risk factors. Excess weight increases the heart's work. It also raises blood pressure and blood cholesterol and triglyceride levels, and lowers HDL ("good") cholesterol levels. Diabetes is more likely to develop. By losing even as few as 10 pounds, you can lower your heart disease risk.
- Diabetes Mellitus - Diabetes seriously increases your risk of developing cardiovascular disease. Even when glucose (blood sugar) levels are under control, diabetes increases the risk of heart disease and stroke. The risks are even greater if blood sugar is not well controlled. Roughly 67% of men and 57% of women with diabetes at age 50 will develop cardiovascular disease by age 75. About three-quarters of diabetics die of some form of heart or blood vessel disease. If you have diabetes, it's extremely important to work with your healthcare provider to manage it and control any other risk factors you can.
- Stress - Individual response to stress may be a contributing factor. Some scientists have noted a relationship between coronary heart disease risk and stress in a person's life, their health behavior, and socioeconomic status. These factors may affect established risk factors. For example, people under stress tend to overeat, smoke more, and increase alcohol consumption.
- Alcohol - Drinking too much alcohol can raise blood pressure, cause heart failure, and lead to stroke. It can contribute to high triglycerides, cancer and other diseases, and produce irregular heartbeat. It contributes to obesity, alcoholism, suicide, and accidents. However the risk of heart disease in people who drink moderate amounts of alcohol (an average of one drink for women or two drinks for men per day) is lower than in nondrinkers. One drink is defined as 1-1/2 fluid ounces (fl oz) of 80-proof spirits (such as bourbon, Scotch, vodka, gin, etc.), 1 fl oz of 100-proof spirits, 4 fl oz of wine or 12 fl oz of beer. It is not recommended that nondrinkers start using alcohol or that drinkers increase the amount they drink to lower risk of cardiovascular disease.
If you reach the age of 50
with none of the above risk factors, the lifetime risk of cardiovascular disease
is just 5% for men and 8% for women. There is a good chance the you will
live into your 90s.
If the age of 50 is
reached with two or more risk factors, then lifetime risk of cardiovascular
disease jumps to 69% for men and 50% for women. The median survival rate
for men and women with two risk factors is a decade shorter than the ones with
none.

Western Medicine
Western medicine relies on aggressive and costly prescription drugs and prohibitively-expensive surgery to deal with problems related to cardiovascular disorders. These methods generally address only the symptoms of cardiovascular disorder and not the underlying causes. As soon as you stop using the drugs, the problems return! And these prescription drugs often result in unwanted and even dangerous side effects.
The options for
drug treatment are bewildering: Alpha Blockers, Angiotensin-Converting Enzyme
Inhibitors, Antiarrhythmic Drugs, Anti-Coagulants, Anti-Platelets, Thrombolytics,
Beta Blockers, Calcium Channel Blockers, Centrally Acting Drugs,
Cholesterol-Lowering Drugs, Digitalis Drugs, Nitrates, Diuretics,
Peripheral Adrenergic Antagonists, and Vasodilators.Western medicine relies on aggressive and costly prescription drugs and prohibitively-expensive surgery to deal with problems related to cardiovascular disorders. These methods generally address only the symptoms of cardiovascular disorder and not the underlying causes. As soon as you stop using the drugs, the problems return! And these prescription drugs often result in unwanted and even dangerous side effects.
Typically once drug treatment begins, it is recommended for life and usually involves a series of medications. The combined side-effects include anxiety, bleeding, bruising, chest pain, cold hands and feet, confusion, constipation, diarrhea, dizziness, dry hacking cough, dry mouth, fainting, fever, headache, heat intolerance, hyperthyroidism, increased blood sugar, indigestion, inflammation of heart, insomnia, intolerance to cold, itching, joint pain, kidney function disruption, liver inflammation, loss of appetite, loss of concentration, low blood sugar, lower blood platelet count, lung inflammation, lupus, memory loss, metallic taste in mouth, muscle degeneration, nausea, nightmares, orthostatic hypotension, palpitations, rapid heart rate, rash, restlessness, ringing in the ears, seizures, severe rise in blood pressure, shallow breathing, skin discoloration, slow heart rate, susceptibility to sunburn, sweats, swelling, temporary impotence, tremors, twitching, urination difficulty, vision disturbances, vomiting, weak heart contractions, weakness, weight gain, weight loss, and worsening of glaucoma.
Surgical options include Angioplasty, Artificial Heart Valve Surgery, Atherectomy, Bypass Surgery, Cardiomyoplasty, Heart Transplant, Implantable Medical Devices (Left Ventricular Assist Device, Pacemaker, Cardioverter Defibrillator), Minimally Invasive Heart Surgery, Radiofrequency Ablation, Stent Procedure, and Transmyocardial Revascularization. All of these surgical procedures carry risk of infection and serious complications, most require follow-on drug treatment for life, and do not guarantee lasting cardiovascular health.

Recommendations
You can optimize your long-term cardiovascular health by:
1) Reversing Damage - Years of stressful living caused damage to your cardiovascular system. To help reverse this, Cardiofy releases hundreds of phytonutrients that act at the molecular level to improve blood circulation, normalize lipid metabolism, regulate cholesterol and triglyceride levels, stimulate liver functions, reduce platelet aggregation, strengthen blood vessels, minimize heart stress, energize heart tissue, and avert hypertension.
2) Avoiding Saturated Fat - Saturated fat is the main dietary cause of high blood cholesterol. Foods to avoid include beef, veal, lamb, pork, lard, poultry fat, butter, cream, milk, cheeses, whole dairy products, two percent milk, coconut, coconut oil, palm oil, tropical oils, and cocoa butter.
3) Avoiding Hydrogenated Fat - Hydrogenated fats raise blood cholesterol. Foods to avoid include margarine and shortening.
4) Avoiding Trans-Fatty Acids - Trans-fatty Acids raise blood cholesterol. Foods to avoid include french fries, doughnuts, cookies, crackers, muffins, pies, and cakes.
5) Consuming Unsaturated Fats - Getting between 25% to 35% of your calories from unsaturated fats will help lower your blood cholesterol level. Foods to consume include salmon, trout, herring, avocados, olives, walnuts, and liquid vegetable oils (soybean, corn, safflower, canola, and sunflower).
6) Reducing Sugar Intake - Cut back on beverages and foods with added sugars to lower your calorie intake and help control your weight. Examples of added sugars are sucrose, glucose, fructose, maltose, dextrose, corn syrups, high-fructose corn syrup, concentrated fruit juice, and honey.
7) Minimizing Salt Intake - Foods low in salt lower your risk of high blood pressure. Strive to consume less than 1,500 mg of salt daily. Choose "reduced-sodium" processed foods and limit soy sauce, steak sauce, Worcestershire sauce, flavored seasoning salts, pickles, and olives. Use lemon juice, citrus zest, and hot chilies instead for flavoring. Rinse canned tuna and salmon, feta cheese, and capers to remove excess sodium.
8) Increasing Fiber Intake - When eaten regularly as part of a diet low in saturated fat and cholesterol, soluble fiber helps to lower blood cholesterol and may also reduce the risk of diabetes and colon and rectal cancers. For every 1,000 calories in your diet, 14 grams of fiber (in both soluble and insoluble forms) should be eaten. Foods high in soluble fibers includes oat bran, oatmeal, beans, peas, rice bran, barley, citrus fruits, strawberries, and apple pulp. Foods high in insoluble fibers include whole-wheat breads, wheat cereals, wheat bran, cabbage, beets, carrots, Brussels sprouts, turnips, cauliflower, and apple skin. Replace low-fiber foods (white bread, white rice, candy and chips) with fiber-rich foods (whole-grain bread, brown rice, fruits and vegetables). Eat more raw vegetables and fresh fruits. Eat high-fiber foods at every meal.
9) Drinking Water - Drink six to eight 8-oz glasses of water a day to ensure fiber in the diet is properly digested and fat loss is optimized.
10) Exercising Daily - A minimum of 30 minutes of moderate exercise every day will help you maintain optimal weight, keep off weight you lose, and improve physical and cardiovascular fitness.
11) Not Smoking - Cigarette smokers are 2 to 3 times more likely to die from coronary heart disease than non-smokers.
12) Consuming Alcohol in Moderation - Drinking too much alcohol can raise triglyceride levels in your blood and also lead to high blood pressure, heart failure, and increase calorie intake (which can lead to obesity and diabetes). Excessive drinking can also cause stroke, cardiomyopathy, cardiac arrhythmia, and sudden cardiac death.

Mix
all and boil for half hour, or until balance of 3 cups. Let it cool,
and then mix 3 cups of natural Raw Honey. Mix again. Transfer to glass
bottle and keep in fridge.
When
we want to get rid of disease instead of de-toxifying our body we jump
to medicine forgetting that god has designed our body in such a way
that it can self – clean, self- correct, self- heal, self- repair, all
it need is the right weapons (healthy food) and ample time (fasting) for
it to battle against diseases.
"Many herbalists recommend the use of raw, unpasteurized, unheated,
apple cider vinegar as an important dietary ingredient for humans, farm
animals and pets, including birds. The Encyclopedia of Natural Pet Care
describes apple cider vinegar in this way: "Long a folk remedy, cider
vinegar has been shown to improve the health of dairy cows, horses, dogs
and other animals. It reduces common infections, aids whelping,
improves stamina, prevents muscle fatigue after exercise, increases
resistance to disease and protects against food poisoning. Cider vinegar
is rich in the vitamins, minerals and trace elements found in apples,
especially potassium; it normalizes acid levels [pH] in the stomach,
improves digestion and the assimilation of nutrients, reduces intestinal
and faecal odours, helps cure constipation, alleviates some of the
symptoms of arthritis and helps prevent bladder stones and urinary tract
infections."
There
is nothing beneficial about commercial distilled vinegars except for
pickling, cleaning and disinfection ---they have no health value! They
do not contain the health values of raw apple cider vinegar with the
mother still intact and viable. Distilled white vinegar and cider
vinegar sold in supermarkets are considered "dead" vinegars with none of
the enzymes and other live factors that make raw, unpasteurized
vinegars so valuable. Distilling removes the beneficial "mother" from
the vinegar, thereby, destroying the powerful enzymes and life giving
minerals such as potassium, phosphorus, natural organic sodium,
magnesium, sulphur, iron copper, natural organic fluorine, silicon,
trace minerals, pectin and other powerful nutrients. Also destroyed are
natural malic and tartaric acids, which are important in fighting body
toxins and inhibiting unfriendly bacteria growth.
When
the blood is deficient in some minerals or biochemic salt, ill-health
is the outcome e.g. boils break out, suppurating blisters become
apparent, pimples appear on the face etc. It has been found however,
that cider vinegar helps with the cleansing as well as the clotting of
the blood. Oxidation of the blood is very important and cider vinegar is
again an effective treatment for this. Besides introducing the
important minerals into the blood stream, as mentioned above, cider
vinegar also helps in the clotting of blood. This is of tremendous help
to those people who are commonly termed 'bleeders', as they live their
lives in fear of cutting themselves due to the bloods inability to clot,
and it will also enhance the healing process.
According
to the logic of ancient medical sciences, arthritis, a wide-spread
chronic disease all over the globe, is caused due to the excretion of
toxins in joints of body. This is caused by destabilized colon and weak
digestion system, leading to the accrual of undigested food and building
up of waste materials.
Evidence
reveals that Apple Cider Vinegar has proven itself once again in
lowering blood pressure and strengthening the heart muscle, because ACV
acts as a blood thinner, plaque remover and reduces risk of strokes and
heart attack. It's also rich in potassium and enzymes, these two are
most vital and needed to keep the heart and bloodstream healthy. Use
standard dosage of ACV 
Many
women have found that Apple Cider Vinegar can help reduce the
appearance of cellulite. It is a skin problem that can affect anyone,
including men, women and children. However, women are often affected the
most, with 95% of all women suffering from this condition to some
extent. It is visually characterized by bulging, pitted, wrinkled, and
dimpled skin on the abdomen, buttocks, hips, and thighs which occur due
to fatty deposits that are concentrated in these areas.
Try
standard dose 3 times a day, it is said that 2 or 3 teaspoons of ACV
to eight-ounces glass of water before meals . Adding dietary fiber, as
contained in AVC, is said to be beneficial in controlling fasting blood
glucose levels. Research has shown that Vinegar can help people with
type 2 diabetes or insulin resistance (not diabetic, but high risk) by
improving insulin sensitivity. In the study, Vinegar was just as
effective as drugs (metformin and acarbose) used to treat diabetes.
Don’t stop your current medication. Check regularly (10days) with your
doctor and decrease the dosage of drugs (Not ACV).
Apple
Cider Vinegar also aids digestion. In helping you break down food as
you should it may prevent the formation of uric acid. Apple Cider
Vinegar is acidic, but once processed by the body it actually has an
alkalizing effect which is thought to be key to vibrant health.
Increasing you pH and becoming more alkaline can make your body more
effective in eliminating uric acid. Malic acid, which is present in
Apple Cider Vinegar breaks down and dissolves sodium urate crystals,
helping you eliminate gout. ACV has a variety of other health benefits
which improve general health and will make your body more able to deal
with excess uric acid, remove excess water and remove toxic waste just
to name a few. 
Kidney
stones are extremely painful, as anyone who has experienced them will
let you know. Kidney stones consist of calcium, which is alkaline.
Vinegar, on the other hand, is acidic. The theory is, supported by many
success stories, that the acetic and phosphoric acids in Vinegar reduce
the size or completely dissolve the kidney stone and allow it to pass
pain-free. 
One
such treatment for the removal of warts involves using Apple Cider
Vinegar. This natural substance works extremely successfully in removing
warts due to its acidic content, and effectively enables the root of
the wart to peel off, ridding the affected area of the virus entirely.
ACV
has been used as a weight loss remedy for centuries. It has been
suggested that the ACV works because it makes the body burn calories
better, reduces appetite and gets the entire metabolism working. But
whatever the reason, the fact remains that it has stood the test of time
and has helped countless people to achieve their ideal weight.
Don't
you dreaded every time the dandruff seems so obvious when you wear your
favourite black colour shirt. Or the times when you need to check your
shoulder first and give it a few good dusting before going out? ACV
rinse might just be the solution for you. Rinsing your hair using
diluted ACV cures dandruff by stopping the growth of malassezia furfur, a yeast-like fungus that causes dandruff and seborrheic dermatitis.
