      • and in the future HTTPS 1 . alpn=h3 no-default-alpn (h3)
  • Against UDP (QUIC) reflection/amplification attacks: Require a QUIC Retry token (it's like a TCP SYN Cookie, otherwise the server would spam its TLS certificate to unvalidated IP addresses). For HTTP3 here.
    • HTTP3 can better handle packet loss + client IP change: HTTP1.1 head-of-line blocking is solved by HTTP2 multiplexing, but it still suffers from TCP head-of-line blocking in case of packet loss. HTTP3 solves that by using UDP QUIC.
    • HTTP3/QUIC pro and contra
• Hardware
  • Against Side-channel attacks: Use CPUs that don't have Simultaneous multithreading (SMT = more than 1 thread per physical core / multiple virtual cores per physical core / Intel Hyper-Threading)

• Organic hardware health security (in progress)
  • Fat (maximum 30 to 35% of daily kcal consumption, e.g. 0,35*1633=571.55 kcal)
    • Fat -> liver -> ketone bodies as energy
    • If too little kcal/day: body fat becomes energy if insulin level is low (insulin peaks must be avoided anyway)
      • (=in case you eat a bit carbohydrates or sugar, way less fat becomes energy, even more muscle mass is consumed and hunger is higher)
    • If too much kcal/day (from sugar, carbohydrates, protein or fat): fat becomes body fat if you eat more kcal than needed
      • resting metabolic rate: idle condition = 1 kcal per hour per kg body weight = e.g. 65kg * 24kcal = 1560kcal
      • basal metabolic rate = Harris–Benedict equation:
        • men: 66,5 + (13,75 * weight in kg) + (5,003 * height in cm) - (6,75 * age)
          • e.g. 66,5 + (13,75 * 65 kg) + (5,003 * 175 cm) - (6,75 * 30 years) = 1633 kcal per day
        • women: 655,1 + (9,563 * weight in kg) + (1,850 * height in cm) - (4,676 * age)
          • e.g. 655,1 + (9,563 * 65 kg) + (1,850 * 175 cm) - (4,676 * 30 years) = 1460 kcal per day
    • saturated fatty acids (maximum 7 to 10% of daily kcal consumption, e.g. 0,07*1633=114.31 kcal)
      • non-essential, the body can synthesize them

        • Palm oil (40–45%), meat (e.g., chicken: 0.7–5 g/100 g), butter, coconut oil.
        • Can raise LDL cholesterol if consumed excessively; moderate intake is generally safe.
      • SA: Stearic Acid (C18:0)
        • Long-chain saturated fatty acid, less harmful than palmitic acid.
        • Neutral effect on cholesterol; partially converted to oleic acid in the body.

          • anti-inflammatory
          • OA: Oleic Acid (C18:1, Omega-9)
            • Most common monounsaturated fatty acid, non-essential (body can produce it from satured fatty acids).
              • Olives also contain antioxidants (e.g., polyphenols, vitamin E), which protect against oxidative stress, unlike synthetic omega-9 produced from saturated fats in the body.
            • Heart-protective, anti-inflammatory; key component of the Mediterranean diet.
            • olives / olive oil (rather for cold cooking. safe with distance below smoke point of 130°C-190°C, you might reach it and harmful substances form.)
            • avocado, canola/rape oil, almonds, palm oil (35–38%)

          • POA: Palmitoleic Acid (C16:1, Omega-7)
            • Macadamia nuts, seaweed, fish oil, trace amounts in olives.
            • May reduce inflammation; less studied but potentially beneficial.
      • polyunsaturated fatty acids (maximum 10% of daily kcal consumption, e.g. 0,1*1633=163.3 kcal)
        • Omega-6
          • If too much: pro-inflammatory (but too less Omega-6 would be unhealthy as well)
            • ⚠️ 50:1 (even 10:1) Omega-6 to Omega-3 ratio is pro-inflammatory and frequent in the West
            • recommended maximum is 5:1, ideal would be 1:1.
            • The same enzyme processes Omega 6 and 3: If all enzymes are "occupied" with omega-6, the body cannot absorb omega-3.
          • LA: Linoleic Acid (C18:2)
            • Most common Omega-6, precursor to arachidonic acid.
            • Essential for cell membranes; excessive intake can promote inflammation.
            • sunflower oil (safe with distance below smoke point of 232-252°C)

          • ALA: Alpha-Linolenic Acid (C18:3) (essential, required for heart and brain health)
            • Essential for cardiovascular health and inflammation reduction; conversion to EPA/DHA is limited, so direct sources are preferred.
            • Linseed/Flaxseed oil for cold cooking (safe with distance below smoke point of ~107°C: Must not be used for frying, otherwise harmful substances form.)
            • chia seeds, walnuts
            • Colza/Rape oil for frying (contains more Omega-6 than Omega-3 ALA. safe with distance below smoke point of 190-230°C)
          • EPA+DHA from Schizochytrium microalgae [1] [2]
            • for brain, eyes, heart, skin

    • fish protein
    • land animal protein
      • white meat (birds: chicken etc)
      • milk
      • ⚠️⚠️ inflammation (if you are a mammal cannibal): Red meat comes from mammals and contains heme iron, which can promote oxidative stress and inflammation in the gut, increasing the risk of colon cancer:
        • Cow, pig, lamb, goat, wild meat (deer, venison, wild boar), horse
      • ⚠️⚠️⚠️ Additional cancer cause: Processed meat includes meat that has been preserved by smoking, curing, salting, or the addition of preservatives (e.g., nitrates, nitrites). These substances can form nitrosamines, which are carcinogenic.
        • Sausages: Salami, ham, bratwurst, Vienna sausages, liverwurst
        • Bacon
        • Cured meats: Corned beef, pastrami
        • Smoked meats: Smoked ham, smoked ribs
        • Canned meats: Canned meat with preservatives
        • Grok Recommendation: Processed meat should be avoided as much as possible or severely limited (e.g., no more than 1-2 times per month).
  • Carbohydrates
    • Indigestible carbohydrates (called fiber)
    • Digestible carbohydrates (the actual Carbohydrates)
      • Carbohydrates become sugar -> insulin goes up -> sugar becomes fat
  • Sugar
    • Sugar -> insulin goes up -> sugar becomes fat
    • ⚠️⚠️ Sugar + lactic acid bacteria that are anyway present in the mouth = lactic acid + more bacteria = pH at/below 5.5 = tooth enamel demineralizes (teeth become slightly yellow because the shell irreversibly becomes thinner, opaque white spot on tooth surface) + caries risk (yellow/brown/black)

  • Physical activity: Any movement that gets the circulation going for at least 10 minutes (makes the heart beat a little faster) temporarily brings the immune system's T cells out of their resting place (lymph nodes and bone marrow) into the bloodstream and lets them go on patrol which helps against cancer.
  • ⚠️⚠️ At and below a pH value of 5.5, tooth enamel is irreversibly damaged, it begins to dissolve/demineralize (teeth become slightly yellow because the shell irreversibly becomes thinner, opaque white spot on tooth surface).
    • later it looks like abraded, you only have the yellow core of the tooth left
    • caries risk (yellow/brown/black)
    • Don't have it multiple times a day, ideally not even daily.
    • Cover your teeth with saliva immediately after drinking/eating
      • Saliva contains calcium and phosphate ions which, together with fluoride toothpaste, lead to tooth enamel remineralization (it prevents further yellowization, nothing more).
        • Bleaching would be required for getting them white again, but the damage can't be repaired, the shell can't be made thicker again.
    • ⚠️⚠️ Phosphoric acid: Cola, Lemonades, iced teas
    • ⚠️⚠️ Citric acid: energy drinks (btw: mouthwash+energydrink=sulfur compounds that smell like rotten egg), sour gummy bears, candies and lollipops, citrus fruits
    • Malic acid: apples
    • ⚠️⚠️Lactic acid: When lactic acid bacteria that are anyway present in the mouth in small numbers come into contact with sugar they reproduce and produce acids (mainly lactic acid).
  • ⚠️⚠️⚠️ Alcohol
    • There is no risk-free amount of consumption: Recommended is zero.
    • Alcohol breakdown products from your liver destroy your DNA: mutation leads to cancer.
    • Alcohol disinfects because it lets cells explode. Alcohol destroys upper layers in your mouth, lower layers need to grow to replace them.
      • When you smoke (smoke contains more than 60 carcinogens that cause cancer) and consume alcohol, then your cancer risk is 100 times higher compared to only smoking.
    • ~13% of breast cancer cases are caused by alcohol
    • Pregnant women who drink alcohol only for 1 day can already make their child violent and disabled.
  • Clean Air
    • ⚠️⚠️⚠️ Microplastics and fine dust from car tire wear, non-magnetic train tire wear, combustion exhaust gases (wood stoves, combustion cars, gas and oil heating, coal-fired power plants) and laundry fibers can cause:
      • neurological damage (microplastics and fine dust get into your blood and even into your brain, they can pass the blood-brain barrier)
