Muscle loss with aging is not just a muscle problem.
It’s a nerve problem as well.

This study shows that what separates frailty from strength in older adults is not muscle mass alone, but the excitability of the motoneurons that drive muscle contraction.

A quick breakdown:
🔵 Motoneurons control strength .👇 Motoneurons determine how strongly and how long muscle fibers fire. Their intrinsic excitability sets the ceiling for force production.

🟣 Sarcopenia starts upstream - older adults with sarcopenia show reduced persistent inward currents, meaning weaker neural amplification of movement commands.

🟡 Athletic aging preserves the signal - Master athletes retain higher motoneuron excitability, stronger PICs, and higher motor unit discharge rates, even at advanced ages.

🟢 Training protects the nervous system Long-term resistance and high-intensity movement appear to preserve motoneuron function, not just muscle size.

🔴 Weakness reflects neural decline - Lower motoneuron excitability correlates directly with poorer physical performance, strength, and functional capacity.

What this means:
• Strength is a neural trait before it’s a muscular one👈
• Aging does not guarantee decline, inactivity does👈
• Exercise preserves nervous system function, not just muscle👈
• Sarcopenia is partly a problem of lost neural drive

Protect the signal, and the muscle can follow.

Many people I test...show elevated levels.

Ladies most lipstick shades especially the darker colors 👇👇👇

Cadmium is used in certain products as a color pigment, especially in yellow and orange shades, however, a recent study found measurable amounts of cadmium in all colors and brands of lipstick tested.

Several other studies found that some of the lipsticks contain cadmium in higher levels than recommended. One study in particular found that cadmium concentrations in almost all samples exceeded the FDA’s acceptable limit of 3mg/kg.

Cadmium is a HIGHLY toxic heavy metal that ACCUMULATES in the body, primarily affecting kidneys, bones, hormones, heart and lungs. Because it has a long half-life, chronic, even low-level exposure can lead to severe health problems over time.

🗂️Effects of Chronic Exposure to Cadmium:

📑Kidney Damage: The kidneys are the primary site of cadmium accumulation, where the metal can remain for DECADES. This causes damage to the kidney tubules, leading to the excretion of proteins and sugars into the urine (Fanconi’s syndrome). Over time, this causes a reduction of kidney filtration and can lead to chronic kidney disease.

📑Bone Disease: Cadmium disrupts the body’s metabolism of calcium, phosphorous and Vitamin D, which are essential for bone health. This can lead to: 1) osteoporosis (a condition characterized by reduced bone mass and density, which significantly increases the risk of fractures); 2) Osteomalacia (softening of the bones); 3) Itai-itai Disease (first discovered in Japan, this extremely painful disease is a severe form of bone and kidney damage caused by high cadmium exposure).

📑Lung Disease: Long-term cadmium exposure can cause irreversible lung damage caused, including emphysema and other obstructive airway diseases. The risk is elevated for smokers and workers in factories.

📑Cancer: Cadmium is classified as a KNOWN HUMAN CARCINOGEN and chronic exposure is strongly linked to an increased risk of lung, kidney, prostate and bladder cancers.

NATURAL ENERGY: HOW IT HAPPENS👇👇👇

Your body isn’t just “tired," your cellular engines are underperforming.

Want more natural energy?

🔥 Move your body → activity stimulates mitochondrial biogenesis
🔥 Eat enough protein & micronutrients → they’re required to run these pathways
🔥 Get sunlight → supports mitochondrial signaling
🔥 Prioritize sleep → mitochondria repair while you rest
🔥 Control stress → chronic cortisol suppresses mitochondrial output
🔥 Breathe deeply → oxygen literally feeds the final step of energy production
🔥 Avoid ultra-processed foods → they disrupt the pathways shown in the graphic

When people say “boost your energy,” THIS is what they’re talking about, improving the most fundamental process your cells use to stay alive.

The more your mitochondria thrive, the better YOU feel: mentally, physically, emotionally.

Energy isn’t motivation.
It’s cellular metabolism.
And you can support it every single day.

We usually learn vitamins as a list, but biology doesn’t use lists. It uses systems.
If you look at this chart the right way, it isn’t a collection of nutrients. It is a map of the reactions that keep you alive.👇👇👇

1️⃣ Vitamins are the switches that turn metabolic pathways on
They activate enzymes for energy production, neurotransmitter synthesis, DNA repair and more.👇👇👇
💡 B12 and folate operate as a paired circuit for methylation and brain function.

2️⃣ Minerals are the structural pieces that let enzymes work
They stabilize reactions, transfer electrons and keep ATP chemistry moving.👇👇👇
💡 Magnesium supports hundreds of reactions, from ATP generation to muscle relaxation.

3️⃣ Antioxidants are the internal defense network👇👇👇
They absorb oxidative stress, regenerate one another and protect membranes and mitochondria.
💡 Vitamin C, vitamin E and CoQ10 form a regenerative loop, not three separate tools.👈

4️⃣ These nutrients are interconnected, not isolated
A gap in one slows multiple systems downstream.👇👇👇
💡 Selenium enables glutathione, B2 activates folate, copper balances iron handling.

5️⃣ Food organizes these nutrients into biologically meaningful combinations
Whole foods deliver co-factors that evolved to work together.👈👈👈(read this twice)
💡 Eggs supply choline, B12, selenium and lutein, a combination no single pill can replicate. Its not just about supplementing, FOOD matters too!

THYROID and INFERTILITY/MISCARRIAGES:

My Lady peeps 👇👇👇HORMONES ARE A BIG DEAL!

Your thyroid contributes like your "3rd o***y".

What does that mean ?

Another question 👇

What happens when the thyroid is not getting sufficient iodine? Your ovaries will get weak n lazy. .

Adrenals and fat cells then take over the function of estrogen production, but the production of progesterone to balance that estrogen typically reduces.

Physical characteristics (a.k.a symptoms):

thinning hair,
weight gain,
low energy
Sleep pattern off
Skin texture changes
S*x drive diminishes
Vaginal dryness
Fertility issues

Pregnancy requires the production of progesterone (pro-gestation). Not only will infertility and miscarriages be common, but unbalanced estrogen overload becomes a THING! THERE are many endocrine disruptors, impostors, and inhibitors causing hormonal imbalances if you'd like to learn more......comment PLZ in the comments 👇👇👇video series COMING IN 2026 😁 ( monthly membership options will be available).....

Dr. Jodi's random food DYK
The low down on 👇👇👇

Cream of tartar is one of those mystery ingredients you might have seen in your grandma's pantry without knowing what it's used for. After all, its name doesn't give you a clue—not like baking powder or baking soda.

Yet just a touch of it makes a big difference in your baking and cooking. Here's what it is and how to use it in recipes.

What is cream of tartar?

First of all, it's not creamy. It's a dry, powdery, acidic byproduct of fermenting grapes into wine. Its sciency name is potassium bitartrate, aka potassium hydrogen tartrate or tartaric acid (hence the commercial name). But you can find it in the spice aisle labeled as plain ol' cream of tartar. It is a byproduct of the wine making process.

What is cream of tartar used for?

Adding a small amount of cream of tartar when you're beating egg whites—usually 1/8 teaspoon per egg white—speeds up the creation of foam and helps stabilize the structure of those miniscule air bubbles you're whipping up. In baking, this means mile-high meringue pies, melt-in-your-mouth meringue cookies, and angel food cakes that practically float off the plate.

Why is cream of tartar in snickerdoodle cookies?

It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Science!

How else is cream of tartar used in recipes?

When combined with baking soda, it becomes a leavening agent (the stuff that makes baked goods puff up in the oven) by producing carbon dioxide gas. If you ever run out of baking powder, you can substitute 1/4 teaspoon baking soda plus 1/2 teaspoon cream of tartar for 1 teaspoon baking powder.

Add a pinch of cream of tartar to boiling vegetables to help them retain their bright, fresh color.

A pinch of cream of tartar also helps stabilize whipped cream to prevent it from deflating.

Make colorful, edible play dough!

What can I substitute for cream of tartar?

Use 2 teaspoons lemon juice or vinegar to create the acidic effect of 1 teaspoon of cream of tartar in a recipe.

What is cream of tartar's shelf-life?

Cream of tartar keeps its freshness indefinitely, as long as you store it in a cool, dry spot. When in doubt, you can test it by looking at it and smelling it. It should look white and powdery, and it should smell mildly acidic.

Electrolyte disorders look chaotic on the surface, but every branch in this chart reflects precise physiological rule. Sodium, potassium, calcium, magnesium, and phosphate don’t drift randomly (they shift according to fluid status, hormones, kidney function, acid-base balance, and cellular redistribution).

This visual approximates the logic used to "decode" those shifts:
• Sodium tracks water balance.
• Potassium mirrors intracellular physiology and renal handling.
• Calcium is suggestive of parathyroid hormone, vitamin D, and bone-kidney signaling.
• Phosphate reflects metabolism and renal thresholds.
• Magnesium quietly modulates all of the above.

Small biochemical changes can alter nerve conduction, cardiac rhythm, muscle function, and cell signaling. This is the physiology behind the symptoms, a reminder that one lab value can map an entire network of underlying processes.

Caffeine metabolism and why coffee hits people differently.....genetic testing option will be available in January .. I will post.more deets after New Year .....

1️⃣ Absorption Is Fast
Caffeine is absorbed in the stomach & small intestine, peaking in blood within 30–60 min.
💡 why that morning espresso kicks in quick.

2️⃣ The Liver Is the Gatekeeper
CYP1A2 enzyme (a liver detox enzyme) breaks caffeine down.
💡 Some people have a “fast” version, others a “slow” one.

3️⃣ Three Metabolites Dominate
Paraxanthine → boosts alertness, fat metabolism.
Theobromine → widens blood vessels (and is in chocolate).
Theophylline → relaxes airways (like old asthma drugs).

4️⃣ Genetics Decide Your Buzz
Fast metabolizers clear caffeine quickly (need more cups).
Slow metabolizers keep caffeine in their system for hours (jitters, insomnia).

5️⃣ Lifestyle Tweaks It
Smoking speeds caffeine breakdown.
Pregnancy & certain meds slow it.
💡 Same coffee, different effects.

6️⃣ Half-Life Matters
Caffeine’s half-life = ~5 hours, but in slow metabolizers it can stretch to 9+.
💡 That 3 p.m. latte may still be in your bloodstream at midnight.

7️⃣ Tolerance Builds
Regular caffeine users adapt at the receptor level, needing more to feel the same effect.
💡 Why quitting leads to headaches & fatigue.

LION'S MANE A Mushroom that offers so many benefits:👇👇👇
For Centuries, mushrooms like reishi, shiitake, maitake and others have been used medicinally throughout Asia to promote vibrant health, build resistance to disease and preserve youth. In traditional Chinese medicine, they are regarded as the highest of tonics.

In the United States, mushrooms are sometimes viewed with suspicion because of certain poisonous or hallucinogenic types. This reputation, however, is rapidly changing as medicinal mushrooms become popular in holistic medicine and are used as nutritional supplements.

Being neither plant nor animal but members of the fungal family, they are sometimes referred to as the Third Kingdom. Their DNA actually puts them closer to humans than to plants.
👇👇👇
Among the 38 thousand species of mushrooms, there are about 50 that are poisonous and another 50 with scientifically validated medicinal value. And, of course, there are the mind-altering "magic mushrooms" that produce hallucinogenic trips similar to those of L*D.

One way mushrooms differ from plants is that they contain no chlorophyll, and so cannot manufacture food energy from the sun. They emerge at night and obtain their energy from decaying plant matter.

THE BRAIN: Lion's main is one of the edible mushrooms widely distributed in Japan and China. Its name comes from its beautiful white icicle like spines. In traditional lore, regular consumption of lion's man is said to give one "nerves of steel" and "The memory of a lion.".

Scientific studies performed in Asia confirm the value of its traditional use as a cardiovascular, respiratory and nervous system tonic.

One variety of the mushroom is marketed as a remedy for gastric and duodenal ulcers and chronic gastritis. In traditional Chinese medicine, lion's mane is used to promote strength, vigor and good digestion and for prevention of gastrointestinal cancer. Its beta glucan composition is very similar to those of some of the most potent anti-cancer mushrooms, such as Agaricus Blazei.

Also, a hot water extract made from lion's mane is considered a health tonic and sports beverage. Japanese studies show that lion's man is able to regenerate neurons by stimulating production of nerve growth factor.

NERVE GROWTH FACTOR belongs to a family of proteins that play a part in maintenance, survival and regeneration of neurons during adult life.

As we age, NGF declines, resulting in less efficient brain functioning. In mice, its absence leads to a condition resembling Alzheimer's disease.

In 1986, two scientists won the Nobel Prize in Physiology/Medicine for the discovery and isolation of NGF. Since its discovery, researchers have been interested in ways of enhancing the uptake of NGF. Because NGF is unable to cross the blood -brain barrier, it cannot be administered as an oral drug.

Accordingly, scientists directed their attention to finding bio-active compounds with a low molecular weight that could pe*****te the blood-brain barrier and could be taken orally to induce synthesis of NGF within the brain.

HERICENONES AND AMYLOBAN: What are these ? A breakthrough occurred when a Japanese research team discovered a class of compounds called hericenones in lion's mane that stimulate production of NGF, causing neurons to regrow. These compounds offer great potential for repairing neurological damage, improving intelligence and reflexes and, even more significant, preventing and treating Alzheimer's disease.

What's more, hericenones are the first active substances found in plants to induce NGF synthesis. Other compounds in lion's mane are also believed to be bioactive.

A fat-soluble fraction isolated from lion's mane, called Amyloban, was found to protect agains endoplasmic reticulum stress and/or oxidatie stress-dependent neuronal cell death caused by toxic beta amyloid peptide.

Beta amyloid peptide is the main component of plaque that develops in the brains of Alzheimer's disease patients, causing destruction of neurons as it progresses. So far, amyloban has been found to contain bioactive dilinoleoly-phosphatidylethanolamine (DLPE) benzoate compounds.

DEMENTIA: A study was conducted usng lion's mane to investigate its effectiveness against dementia in a rehabilitative hospital in Japan.

The study consisted of 50 patients in the experimental group and 50 controls. Seven of the patients in the experimental group suffered from different types of dementia. The patients in this group received 5 grams of dried mushroom per day in their soup for a 6 month period.

All patients were evaluated before and after the treatment period for their Functional Independence Measure (FIM), which is an international evaluation standard of independence in physical capabilities (eating, dressing evacuating, walking, bathing/showering, etc.) and in perceptive capabilities (understanding, expression, communication, problem-solving and memory).

Results showed that after 6 months of taking lion's mane, six out of the seven patients experienced improvements in their overall FIM scores. In particular, three bedridden patients were able to get up to eat meals after administration.

Laboratory tests showed no adverse effects of lion's mane. These studies are very encouraging, and more extensive clinical studies are currently underway at other hospitals.
Presently, there is no cure for Alzheimer's disease, and conventional treatments only address the symptoms of the disease. It has been suggested, however, that NGF or lion's mane compounds may be used to prevent and treat Alzheimer's disease and other types of dementia. An effective way to reduce the risk of dementia might be the daily intake of pure, whole foods or dietary supplements that stimulate NGF and inhibit toxicity of beta amyloid peptide.

This is proof that the body can be assisted through that which grows wild. Medicine of the future... just maybe!

In case you think I may have grasped this from thin air.👇👇👇

Jalapeños: How to Tell If They're Hot or Mild Before You Buy Them

Look for little white marks or spots on the skin of the jalapeño. If you see them, the pepper is likely to be hotter than one without these marks, which tends to be milder. The presence of these marks indicates higher capsaicin levels, the compound responsible for the heat.
