    What food has the most amygdalin?
    Amygdalin is most abundant in Plum seeds, especially the Green and Black Plums; amygdalin content of Plum seems highly dependent on variety (Table 1). The values reported in this study was similar to the amygdalin content of Plum kernels (12.7 mg/g) reported by Haque & Bradbury (2002).

    What does apricot kernels do to the body?
    AI Overview
    Apricot kernels contain amygdalin, a compound that releases cyanide when ingested, posing a risk of cyanide poisoning if consumed in large quantities, especially for children. 
    Here's a more detailed explanation:
    • Cyanide Risk:
      Apricot kernels, particularly bitter varieties, naturally contain cyanogenic glycosides, with amygdalin being the primary one. 
    • Amygdalin and Cyanide:
      When amygdalin is ingested, it can break down and release cyanide, a toxic substance. 
    • Potential Health Effects:
      • Mild to Moderate: Difficulty breathing, bluish discoloration of the skin or mucous membranes, weakness, and lightheadedness. 
      • Severe: Coma, seizures, stupor, dysrhythmias, cardiovascular collapse, and metabolic acidosis. 
    • Safe Consumption:
      • Processing: Proper processing methods, such as soaking, boiling, or deskinning, can reduce cyanide content and make kernels safer to consume. 
      • Moderation: Even with processing, it's crucial to consume apricot kernels in moderation. 
      • Health Canada: Health Canada has established a maximum level of 20 ppm total extractable cyanide in apricot kernels sold as food. 
    • Traditional Uses:
      In traditional Chinese medicine, apricot kernels are used as an antitussive/expectorant. 
    • Cancer Claims:
      While some claim apricot kernels can treat cancer, there's no scientific evidence to support this. 
    • Other Cyanogenic Foods:
      Amygdalin is also found in other foods like apple seeds, cherry pits, and almonds.

      Things to know
      Function…Amygdalin function
      Amygdalin, a naturally occurring compound found in certain plants and seeds, is known for its potential to induce apoptosis (programmed cell death) and inhibit cell proliferation, making it a focus of research for its potential anticancer and other therapeutic effects, although it also releases cyanide upon metabolism. 
      Here's a more detailed look at amygdalin's function:
      1. Anticancer Potential:
      • Apoptosis Induction:
        Amygdalin has been shown to stimulate apoptosis in various cancer cells, including prostate, cervical, and bladder cancer cells, by upregulating pro-apoptotic proteins (like Bax) and downregulating anti-apoptotic proteins (like Bcl-2). 
      • Cell Cycle Arrest:
        Amygdalin can inhibit cell cycle progression in cancer cells, potentially halting their growth and proliferation. 
      • Inhibition of Tumor Growth and Metastasis:
        Studies suggest amygdalin can reduce tumor volume and inhibit the spread of cancer cells, both in vitro and in animal models. 
      2. Other Potential Therapeutic Effects:
      • Immunomodulation:
        Amygdalin can modulate the immune system, potentially improving immune function by inhibiting certain immune signaling molecules (like TGF-β) and regulating T-lymphocyte activity. 
      • Anti-inflammatory Effects:
        Amygdalin has shown anti-inflammatory properties by inhibiting the production of inflammatory molecules (like TNF-alpha and IL-1beta). 
      • Neuroprotective Effects:
        Amygdalin may exert neurotrophic effects, potentially protecting nerve cells from damage and promoting their growth. 
      • Anti-fibrotic Effects:
        Amygdalin has been studied for its potential to prevent or alleviate fibrosis in various organs, including the liver, kidneys, and lungs. 
      3. Cyanide Toxicity:
      • Metabolic Breakdown:
        Amygdalin is metabolized in the body, releasing cyanide, which can be toxic at high doses. 
      • Safety Concerns:
        Due to the potential for cyanide toxicity, the use of amygdalin as a therapeutic agent requires careful consideration and research to determine safe dosages and administration methods. 
      4. Historical Context and Misconceptions:
      • Laetrile:
        Amygdalin is also known as laetrile, a name given to a synthetic form of the compound that was marketed as a cancer treatment, but it has not been shown to be effective or safe in controlled clinical trials.
      • "Vitamin B17":
        Laetrile has been falsely promoted as "vitamin B17," which is not a recognized vitamin.

        Health Benefits…what are the benefits of eating apricot seeds
        Apricot kernels, particularly sweet varieties, offer potential health benefits as they are rich in vitamins, healthy fats, protein, and fiber, contributing to antioxidant and anti-inflammatory properties. However, it's crucial to note that bitter apricot kernels contain amygdalin, a cyanogenic glycoside, and should be consumed with caution or avoided entirely due to the risk of cyanide poisoning. 
        Here's a more detailed look at the potential benefits and risks:
        Potential Benefits:
        • Nutrient-Rich:
          Apricot kernels are a good source of vitamins (especially vitamin E), healthy fats, protein, and fiber. 
        • Antioxidant and Anti-inflammatory:
          They contain polyphenolic compounds that contribute to their antioxidant and anti-inflammatory properties. 
        • Promotes Healthy Digestion:
          The high fiber content can promote a healthy gastrointestinal system. 
        • May Help with Cholesterol:
          Some studies suggest they can play a positive role in cholesterol absorption. 
        • Traditional Uses:
          In traditional Chinese medicine, apricot kernels are used as an antitussive/expectorant. 
        • May help with energy levels:
          They contain iron and phosphorus which can help maintain energy levels and reduce fatigue. 
        Potential Risks and Considerations:
        • Cyanide Poisoning:
          Bitter apricot kernels contain amygdalin, which can release cyanide when metabolized. 
        • Laetrile Myth:
          The claim that apricot kernels or amygdalin can cure cancer is a myth, and there's no scientific evidence to support this. 
        • Consumption Guidelines:
          It's crucial to consume sweet apricot kernels in moderation and to avoid bitter apricot kernels altogether or seek professional guidance before using them. 
        • Safety Concerns:
          The sale of raw apricot kernels has been prohibited in some countries due to the risk of cyanide poisoning. 
        • Moderation is Key:
          Even with sweet apricot kernels, moderation is important due to their high calorie content.

          Amygdalin is classified as a cyanogenic glycoside, because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase. Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning.
