A surprising number and variety of physical problems and diseases can be caused by the problem of foods that are acid-producing after digestion. Today the vast majority of the populace in industrialized nations suffers from problems caused by the stress of acidosis ( 酸液過多症 ), because both modern lifestyle and diet promote acidification of the body's internal environment.
酸液過多症成因 The current typical Western diet is largely composed of acid-forming foods (proteins, cereals, sugars). Alkaline-producing foods such as vegetables are eaten in much smaller quantities. Stimulants ( 興奮劑 ) like tobacco, coffee, tea, and alcohol are also extremely acidifying. Stress, and physical activity (both insufficient or excessive amounts) also cause acidification.
Many foods are alkaline-producing or neutral by nature, but manufactured processed foods are mostly acid- producing and these are the ones most heavily advertised in the media, and filling the shelves of supermarkets. The whole issue is denigrated ( 抹黑 ) as pseudo- science by many in the medical establishment.
It is important to consume at least 60% alkaline-producing foods in our diet, in order to maintain health. We need plenty of fresh fruits and particularly vegetables (alkaline-producing) to balance our necessary protein intake (acid-producing).
And we need to avoid processed, sugary or simple-carbohydrate foods, not only because they are acid-producing but also because they raise blood sugar level too quickly - with high glycemic index ( 升糖指 數 ), therefore fattening and stressing our insulin response - plus they tend to be nutrient-lacking and may be toxic too.
The body maintains correct pH in the blood at all costs, by homeostasis ( 體內平 衡 ), but that is stressful for the body's systems and resources when the diet is unbalanced in terms of acid-forming foods (the residue after digestion, that is).
身體的酸鹼值 Water is the most abundant compound in the human body, comprising 70% of the body. The body therefore contains a wide range of solutions, which may be more or less acid.
pH (potential of Hydrogen) is a measure of the acidity or alkalinity of a solution - the ratio between positively charged ions (acid-forming ， H + ) and negatively charged ions (alkaline-forming, OH -.) The pH of any solution is the measure of its hydrogen-ion concentration. The higher the pH reading, the more alkaline and oxygen rich the fluid is.
The lower the pH reading, the more acidic and oxygen deprived the fluid is. The pH range is from 0 to 14, with 7.0 being neutral. Anything above 7.0 is alkaline, anything below 7.0 is considered acidic.
Human blood pH should be slightly alkaline (7.35 - 7.45). Below or above this range means symptoms and disease. If blood pH moves below 6.8 or above 7.8, cells stop functioning and the body dies. The body therefore continually strives to balance pH. When this balance is compromised ( 危及 ) many problems can occur.
An imbalanced diet high in acidic- producing foods such as animal protein, sugar, caffeine, and processed foods puts pressure on the body's regulating systems to maintain pH neutrality. The extra buffering required can deplete the body of alkaline minerals such as sodium, potassium, magnesium, and calcium, making the person prone to chronic and degenerative ( 退化性 ) disease.
Minerals are borrowed from vital organs and bones to buffer (neutralize) the acid and safely remove it from the body. Because of this strain, the body can suffer severe and prolonged damage--a condition that may go undetected for years.
身體酸化引起的問題 Research shows that unless the body's pH level is slightly alkaline, the body cannot heal itself. So no matter what means you choose to take care of your health, it won't be effective until the pH level is balanced. If your body's pH is not balanced, for example, you cannot effectively assimilate vitamins, minerals and food supplements. Your body pH affects everything.
Acidosis ( 酸液過多症 ) will decrease the body's ability to absorb minerals and other nutrients, decrease the energy production in the cells, decrease it's ability to repair damaged cells, decrease it's ability to detoxify heavy metals, make tumor cells thrive, and make it more susceptible to fatigue and illness.
An acidic pH can occur from an acid- forming diet, emotional stress, toxic overload, and/or immune reactions or any process that deprives the cells of oxygen and other nutrients. The body will try to compensate for acidic pH by using alkaline minerals. If the diet does not contain enough minerals to compensate, a build up of acids in the cells will occur.
Premature aging. Osteoporosis ( 骨質疏鬆 ) and joint pain. Aching ( 疼痛的 ) muscles and lactic acid ( 乳酸 ) buildup. Low energy and chronic fatigue. Slow digestion and elimination. Yeast/fungal ( 酵母菌 / 真菌 ) overgrowth. Lack of energy and fatigue.
Lower body temperature. Tendency to get infections ( 感染 ). Loss of drive ( 幹勁 ), joy ( 歡樂 ), and enthusiasm ( 熱忱 ). Depressive ( 憂鬱 ) tendencies. Easily stressed. Pale complexion ( 膚色 ). Headaches.
Inflammation of the corneas ( 角膜 ) and eyelids ( 眼瞼 ). Loose and painful teeth. Inflamed, sensitive gums ( 齒齦 ). Mouth and stomach ulcers ( 潰瘍 ). Cracks at the corners of the lips. Excess stomach acid. Gastritis ( 胃炎 ).
Nails are thin and split easily. Hair looks dull, has split ends, and falls out. Dry skin. Skin easily irritated. Leg cramps ( 抽筋 ) and spasms ( 痙攣 ).
Spasm vs. Cramp The difference between a muscle spasm and a muscle cramp is the force of the contraction. If a muscle quickly contracts and releases without pain, it is a spasm. A prolonged and painful contraction is a cramp.
酸鹼值檢測 By using pH test strips (Litmus Paper ，石 蕊試紙 ), you can determine your pH factor quickly and easily in the privacy of your own home. The best time to test your pH is about one hour before a meal and two hours after a meal.
Saliva pH Test Simply wet a piece of Litmus Paper with your saliva ( 唾液 ). While generally more acidic than blood, salivary pH mirrors the blood and tells us what the body retains. It is a fair indicator of the health of the extracellular fluids and their alkaline mineral reserves.
The optimal pH for saliva is 6.4 to 6.8. A reading lower than 6.4 is indicative of insufficient alkaline reserves. After eating, the saliva pH should rise to 7.5 or more. To deviate from an ideal salivary pH for an extended time invites illness. If your saliva stays between 6.5 and 7.5 all day, your body is functioning within a healthy range.
Acidosis, an extended time in the acid pH state, can result in rheumatoid arthritis ( 風 濕性關節炎 ), diabetes, lupus ( 狼瘡 ), tuberculosis, osteoporosis ( 骨質疏鬆 ), high blood pressure, most cancers and many more. If salivary pH stays too low, the diet should focus on fruit, vegetables and mineral water as well as remove strong acidifiers such as sodas, whole wheat and red meat.
Urine pH Test The pH of the urine indicates how the body is working to maintain the proper pH of the blood. The urine reveals the alkaline (building – anabolic ，合成 ) and acid (tearing down – catabolic ，分解 ) metabolic cycles. The pH of urine indicates the efforts of the body via the kidneys, adrenals ( 腎上腺 ), lungs and gonads ( 生殖腺 ) to regulate pH through the buffer salts and hormones.
Urine can provide a fairly accurate picture of body chemistry, because the kidneys filter out the buffer salts of pH regulation and provide values based on what the body is eliminating.
Urine pH can vary from around 4.5 to 9.0 in extremes, but the ideal range is 6.0 to 7.0. If your urinary pH fluctuates between 6.0 to 6.5 first thing in the morning and between 6.5 and 7.0 in the evening before dinner, your body is functioning within a healthy range.
Urine testing may indicate how well your body is excreting acids and assimilating minerals, especially calcium, magnesium, sodium and potassium. These minerals function as “buffers.“( 緩衝物 ) Buffers are substances that help maintain and balance the body against the introduction of too much acidity or too much alkalinity.
Even with the proper amounts of buffers, acid or alkaline levels can become stressful to the body's regulatory systems. When the body produces too many of these acids or alkalis, it must excrete the excess.
The urine is the method the body uses to remove any excess acids or alkaline substances that cannot be buffered. If the body's buffering system is overwhelmed, a state of "autointoxication" ( 自體中毒 ) exists, and attention should be given to reducing this stress.
鹼性飲食的作用原理 The concept is actually fairly simple - the diet just focuses on regaining the balance that was lost when man started to eat a more domesticated diet.
Instead of focusing on foods that are high in sugar, simple carbohydrates (like white bread and chips) and fatty meat and dairy... an alkaline diet primarily moves the balance toward fresh fruits and vegetables, whole grains, wholesome protein sources such as beans and legumes, and healthy oils such as olive and flax ( 亞麻 ) seed.
These foods may be either alkaline or acid in their natural state, but after the process of digestion they all produce what is termed as an "alkaline ash" once digested and metabolized by the body. When the body's pH is kept at a slightly alkaline level, all the systems can work more efficiently.
beans and legumes A legume ( 豆科植物 ) is simply a plant with a fruit that grows in the form of a pod, though not all plants with pods ( 豆夾 ) are legumes. Classic legumes include peas, beans or penauts. Typically the pods are not eaten.
A bean ( 豆實 ) is just a seed of a certain variety pf plant species. But these days we refer to the whole plant are “beans”. Classic beans include green beans ( 四季豆 ), lima beans ( 皇帝豆 ), soybeans, chickpeas ( 鷹嘴豆 ), kidney beans ( 花豆 ), pinto beans ( 斑豆 ), or black- eyed beans.
In other words, beans are legumes, but not all legumes are beans.
身體酸鹼值的影響 The pH level of the body has the ability to affect every single cell of the body. When the blood has an alkaline pH instead of an acidic pH, it will have a positive effect on how every bodily system functions. The brain, circulatory system, nerves, muscles, respiratory system, digestive system, and reproductive system can all benefit from a proper pH level.
On the other hand, when the pH of the body is too acidic, it is susceptible to many diseases and problems. Weight gain, heart disease, premature aging, fatigue, nerve problems, allergies, muscle disease and cancer are all more prevalent ( 普遍的 ) when the body's pH is not optimal.
Because these problems are all more likely to occur when the body's pH is too acid, it makes good sense to eat a diet rich in alkalizing foods. The primary goal is usually to eat approximately 75-80% alkaline foods along with only about 20- 25% acidifying foods. If this level is maintained in the diet, the end result is a slightly alkaline pH in the body, which is perfect for optimum good health.
鹼性食物的種類 It's actually quite easy to eat a diet rich in alkaline-producing foods. Most fresh fruits and vegetables are excellent choices. Red meat is not a good choice, but you can add plenty of protein to your meals by using soy products, delicious beans, legumes, and nuts such as almonds.
You should eliminate unhealthy fats from your diet, but you can use good fats such as olive, canola ( 菜籽油 ), and flax seed oil. High fat dairy products should be avoided, but you can drink soy milk and goat's milk. Cheeses made from soy milk and goat's milk would also be good choices.
Replace the empty calories of soda with delicious iced herb tea, green tea and lemon water. Coffee should be avoided, but you can drink hot herbal or green tea. Replace pasta ( 義大利通心粉，細麵條 ) with healthy whole grains such as wild rice, millet and quinoa ( 藜麥 ).
When sweetening your foods, focus on natural products such as raw sugar, Stevia ( 甜菊 ) and maple sugar. As you can see, you'll have many nutritious choices that are both delicious and high in alkalizing properties.
食物酸鹼性的迷思 Note that a food's acid or alkaline-forming tendency in the body has nothing to do with the actual pH of the food itself. For example, lemons are very acidic, however the end-products they produce after digestion and assimilation are alkaline so lemons are alkaline-forming in the body.
Likewise, meat will test alkaline before digestion but it leaves acidic residue in the body so, like nearly all animal products, meat is classified as acid-forming.
身體酸鹼值的維持和調整 To maintain health, the diet should consist of at least 60% alkaline forming foods and at most 40% acid forming foods. To restore health, the diet should consist of 80% alkaline forming foods and 20% acid forming foods.
there are inconsistencies between the acid- or alkaline-forming values given in the lists provided by many websites, and few reliable references. Sites copy information (and errors) from each other and we're not scientific institutes.
Nevertheless, the principles are clear: eat plenty of vegetables, some fruit daily, and don't eat too much of dairy products, grain products, and direct protein from eggs, meat and fish (as is typically the case in Western diet).
But remember... you don't have to cut out all acid-forming foods - some are necessary, typically 40% - otherwise you probably wouldn't get enough protein and variety of nutrients, yet alone make interesting meals that you enjoy. But you DO want to shift the overall balance of your diet over toward the alkaline, and away from the excessively acid-forming diet of a quick-food culture.
Free range eggs, fish, beans, unsaturated oils - these are healthy foods, low glycemic and nutritious, and even if marginally acid-forming (or alkaline or between the two depending on how you measure or what chart you read). They are NOT the culprits ( 罪犯 ) in an acid-forming diet.
The real culprits are highly sweetened foods, pastries, red meat, colas and highly processed foods - these are the ones to reduce to a sensible amount or cut out of your diet if they also contain stimulants and undesirable chemical additives.
Similarly, be sure to include your share of the high alkaline-forming foods to balance those low-acid foods you eat for their overall nutritional value. And make alkaline choices, e.g. better to have brown rice than white rice, even though both are on the acid-forming side, because it moves you in the right pH direction - less acid - and also it is more healthy and nutritious in other respects.
新鮮天然果菜汁 All natural, raw, vegetable and fruit juices are alkaline-producing. (Fruit juices become more acid-producing when processed and especially when sweetened.)
酸性檸檬變鹼性 The answer is simply that when we digest the food, it produces alkaline residue. That's why we classify it as an alkaline food. When we digest a food it is chemically oxidized ('burned') to form water, carbon dioxide and an inorganic compound.
The alkaline or acidic nature of the inorganic compound formed determines whether the food is alkaline or acid- producing. If it contains more sodium ( 鈉 ), potassium ( 鉀 ) or calcium ( 鈣 ), it‘s classed as an alkaline food. If it contains more sulphur ( 硫 ), phosphate ( 磷酸 ) or chloride ( 氯 ), it's classed as an acid food.
毒性血液 In order for the body to remain healthy and alive, your body keeps a delicate and precise balance of blood pH at 7.365, which is slightly alkaline. The body does whatever it has to in order to maintain this balance. The problem is that most people have incredibly acid lifestyles. Acid is produced in your body whenever you have stress, upset emotions and when the food you eat is acid-forming.
The typical diet is significantly acidic. So what happens to your body when you're over-acid? Your body will store excess acid in your fat cells (which is why so many people have such trouble losing weight).
Over time, your body will leach calcium and alkaline stores from your bones in a desperate attempt to retain the pH balance in your body (which is why some people "shrink" as they get older).
Your blood plays a very important role in your healthy and energy: it carries oxygen to all your cells! This gives you energy, and it's what keeps you alive. It also plays a key role in how energizing your sleep is.
When the blood cells are apart from each other, your blood can move freely throughout your entire body, and get into all your small capillaries, so you feel like your whole body is getting energy. During deep sleep, proper blood flow and hydration is important. When your blood looks like this, your sleep is also really energizing and you need less of it!
Blood cells have a negative charge on the outside and a positive charge inside; this is what keeps them healthy and far apart from each other. However, when your body is over-acidic, the acid strips your blood of its negative charge. Your blood cells no longer have the same repelling force and clump together.
When your blood is clumped together, it no longer can get to all the little capillaries in your body to give you the life giving oxygen you need. It no longer can give ever cell of your body the energizing and rejuvenating ( 恢復精神 ) effects.
This is the major reason why some people feel horrible when they wake up, and why they need to sleep longer. It‘s also why you tend to wake up feeling de-hydrated ( 脫水 ).
The truth is most of us create toxic environments inside of our body and this is why disease and fatigue happens. It doesn't happen TO YOU, instead, "you" make it happen...
There are a few other things, in addition to diet, that can be done to help correct an over acidic balance. These include taking enzyme supplements, organic calcium and magnesium supplements, colloidal ( 膠狀 ) minerals, vitamin A and D, and drinking alkaline vegetable juices (carrot, celery and beet) and lemon/maple syrup drink.
We can remedy our over-acidic bodies in the short term with alkalizing supplements, but going forward, we must also choose a diet which is balanced on the side of alkaline-forming foods.
Fortunately most of these are also low glycemic, which takes care of the second primary factor in our creating a healthy diet. Ensure adequate Omega 3 with oily fish in our diet, which is another primary factor, and we can be sure to live long and healthy lives.###
