磷酸鈉

Usage in food

Sodium phosphate can be found in fast food, deli meats, processed meats, canned tuna, baked goods, and other processed foods. It provides multiple functions:
  • It thickens food. It can stabilize the texture of processed foods, such as mashed potatoes.
  • It can treat meat and meat products. It helps keep deli meats and bacon moist and prevents spoilage.
  • It is a leavening agent. It helps to ferment the dough in commercially prepared cakes and breads and cake mixes.
  • It is an emulsifier. It acts as a stabilizer, allowing oil and water to mix together in certain types of food, such as processed cheese.
  • It can balance the pH value in processed foods. Stabilize the acid-base balance, extend the shelf life, and improve the taste.

Is it safe to eat?

Food grade sodium phosphate is classified by the FDA as GRAS, which means "generally recognized as safe." This may be due to the relatively low content of sodium phosphate added to processed foods.
A study found that when sodium phosphate is used as a food additive, its health effects are different from those of natural phosphate. This is because the way it is absorbed by the body is different. According to the abstract, high levels of phosphate may increase the mortality rate of the general public as well as those suffering from kidney and cardiovascular diseases. Researchers have linked high phosphate levels with accelerated aging and vascular damage. Researchers recommend that people eat foods that contain natural phosphate, rather than foods with added sodium phosphate.

Side effects of excessive sodium phosphate may include:

  • Vomit
  • Headache
  • Decreased urine output
  • Bloating
  • stomach ache
  • Dizziness
  • Arrhythmia

Who should avoid sodium phosphate?

Discuss your use of sodium phosphate with your doctor, especially if you are taking it as a supplement or eating large amounts of processed food or fast food.

People with certain diseases should avoid taking this substance. These include:

  • Kidney disease
  • Intestinal tear or blockage
  • Colitis or slow bowel movements
  • heart failure
  • Allergy to sodium phosphate

If you are currently taking certain medications, your doctor may also recommend that you reduce your intake. Before taking it, be sure to discuss your medication history with your doctor, including the herbal supplements you use.

Foods containing sodium phosphate

Foods containing natural sodium phosphate include:
  • Nuts and beans
  • Meat
  • fish
  • poultry
  • Egg

Foods that may have added sodium phosphate include:

  • Bacon
  • Deli meat
  • fast food
  • Processed foods, such as ready-to-eat foods
  • Commercially prepared baked goods and cake mixes
  • Canned tuna

Generalize

Sodium phosphate is naturally found in many foods. It is also added to food to maintain freshness, change texture, and achieve various other effects. The FDA considers sodium phosphate to be safe, but some people should avoid it, including those with kidney disease. If you are concerned about the intake of sodium phosphate or before using it as a supplement, be sure to consult your doctor.

成年後懷疑自己有注意力不足過動症(ADHD),應該接受診斷嗎?

在過去,注意力不足過動症(Attention-Deficit/Hyperactivity Disorder, ADHD)多被視為「小孩的病」,很多成年人小時候從未被評估或診斷。直到近年社會對心理健康重視度提升,許多成人才開始懷疑,自己長期以來的專注困難、健忘、衝動或時間管理不良,可能與 ADHD 有關。這種「晚發現」的情況相當普遍,也引發了問題:成年後是否值得接受 ADHD 診斷?

電擊槍的機制與對人體健康影響

在現代執法中,警察常使用所謂「非致命性武器」(less-lethal weapons),其中最廣為人知的便是 電擊槍(Taser)。電擊槍的設計初衷是提供一種介於徒手制服與槍械之間的選擇,藉由暫時性電擊使嫌疑人失去行動能力,以降低致命暴力發生的風險。然而,電擊槍並非完全無害,背後涉及的電流機制與人體生理反應值得深入探討。
