Speaker 1: Afternoon, everybody. It is July sixteenth, twenty twenty six. Talk
Speaker 1: today about five new discoveries about kidneys that are changing
Speaker 1: how scientists think. New research suggests kidney's influence more than
Speaker 1: just your fluid balance. We'll dive into this because this
Speaker 1: one's near and dear to me, as today happens to
Speaker 1: be my fifteen year anniversary of being cancer free. All agree, Hi,
Speaker 1: and welcome to Health Talk with Doctor Lynn. Your daily
Speaker 1: does The information you hear on the show is informational.
Speaker 1: It's not meant to diagnose or treat any disease. Any
Speaker 1: kind of complete health conditions must be checked out and
Speaker 1: discussed with your primary care physician. Get ready for the
Speaker 1: good news of the day. God bless you folks, and
Speaker 1: here is doctor Lynn. They're daily devotional today comes from
Speaker 1: the Book of Psalms, chapter forty. Self. Pity is a slimy,
Speaker 1: bottomless pit. Once you fall in, you tend to go
Speaker 1: deeper and deeper into the mire. As you you slide
Speaker 1: down those slippery walls, You're well on your way into depression,
Speaker 1: and the darkness is profound. Your only hope is to
Speaker 1: look up and see the light of My presence shining
Speaker 1: down on you. Though the light looks dim from your
Speaker 1: perspective deep in the pit, those rays of hope can
Speaker 1: reach you at any depth. While you focus on me
Speaker 1: and trust, you rise ever so slowly out of the
Speaker 1: abyss of despair, finding you can reach up and grasp
Speaker 1: my hand. I will pull you out into the light again.
Speaker 1: I will gently cleanse you, washing off the clinging mire.
Speaker 1: I will cover you with my righteousness and walk with
Speaker 1: you down the path of life. Stay tuned seven two, seven, nine, one, six, four, two,
Speaker 1: one five five. New discoveries by kidneys are changing how
Speaker 1: scientists think. Many people think of the kidneys as glorified filters.
Speaker 1: New research, early unpublished and so far mostly on animals,
Speaker 1: suggest these two fists sized organs do far more than
Speaker 1: we thought. Our kidneys appear to be in constant conversation
Speaker 1: with the immune system. Highlight that underline that kidneys commune
Speaker 1: system and even with our cravings. Presented at the American
Speaker 1: Physiological Societies Control of Renal Function and Health Disease Conference,
Speaker 1: the findings offer a glimpse and how quickly scientists understanding
Speaker 1: of kidney functions evolving. Number one kidneys may help drive
Speaker 1: your salty cravings scientists have traditionally viewed salt appetite as
Speaker 1: something controlled largely by the brain. Whoever, new findings suggests
Speaker 1: the urge to seek hot salt may arise from a
Speaker 1: conversation between the kidneys and the brain. The kidneys are
Speaker 1: an active participant in shaping salt intake behavior. The kidneys
Speaker 1: are an underregulated salt influence fluid balance. They also contain
Speaker 1: sensory nerves that continue to send information of the brain
Speaker 1: about the body's internal state. The test to test whether
Speaker 1: these signals affect salt appetite, researchers first depleted rats of
Speaker 1: sodium and fluid, then beay them access to both water
Speaker 1: and a salty solution. Rats with intact kidney nerve signaling
Speaker 1: drinks significantly more of the salty solution than rats whose
Speaker 1: kidney sensory nerves have been disconnected, while water intake stayed
Speaker 1: about the same in both groups. Findings get off explain
Speaker 1: why cutting back on sodium can be difficult for some
Speaker 1: people and may point researchers to new ways to manage
Speaker 1: excess salt. Number two, When you eat is as important
Speaker 1: as what you eat. Most advice for protecting kidney health
Speaker 1: focuses on what you eat, especially limiting excess sodium. However,
Speaker 1: a new study in rats prone to salt sensitive high
Speaker 1: blood pressure suggests that when you eat matters as much
Speaker 1: as what you eat. Researchers found that whose foods was
Speaker 1: limited to daily eating window, a pattern known as time
Speaker 1: restricted feeding, showed molecular changes in the kidney consistent with
Speaker 1: reduced inflammation compared with rats that could eat whenever they wanted.
Speaker 1: Researchers took two groups of rats and fed them a
Speaker 1: salt diet. One group was allowed to eat salty food
Speaker 1: whenever they wanted. The other was put on an intermittent
Speaker 1: fasting routine. They were only allowed to eat the salty
Speaker 1: food during a specific window of time each day. Even
Speaker 1: though they ate the same salty food, The fasting group
Speaker 1: had healthier kidneys. Their kidney showed less inflammation. Their bodies
Speaker 1: naturally turned on genes that helped the kidneys burn energy
Speaker 1: from fats and carbohydrate more efficiently. Researchers found evidence of
Speaker 1: increased glucose neogenesis, a process in which the kidneys produced glucose.
Speaker 1: May all reflect broader metabolic changes associated with time restricted feeding.
Speaker 1: Number three, Exercise may help the kidneys recover from injury.
Speaker 1: Exercise is done to support the heart, muscles, and metabolism. Now,
Speaker 1: a new study in mice suggests it may also help
Speaker 1: the kidneys recover from certain types of injury. Researchers found
Speaker 1: that mice allowed to exercise voluntarily for several weeks recovered
Speaker 1: more quickly from a common type of kidney injury known
Speaker 1: as aeschemic reperfusion injury. Three days after the injury, signs
Speaker 1: of kiddy damage had largely returned toward normal in the
Speaker 1: exercise mice, while sedentary mice continue to show signs of
Speaker 1: ongoing injury. Number four. Some immune cells may help keep
Speaker 1: blood pressure in check. New research existed some immune cells
Speaker 1: may help protect against high blood pressure. Researchers studying salt
Speaker 1: sensitive hypertension, a condition which blood pressure rises more dramatically
Speaker 1: and responds to eating salty foods, found that removing certain
Speaker 1: immune cells, known as myloid cells, worsened hypertension rather than
Speaker 1: improving it. Mice lacking these cells experienced larger increase of
Speaker 1: blood pressure, retained more sodium, and showed poor blood vessel
Speaker 1: function produce less nitric oxide, a molecule that helps keeps
Speaker 1: blood vessels relaxed and maintain healthy blood flow. The finding
Speaker 1: suggests at least some of the immune cells help the
Speaker 1: body manage excess dietary salt by supporting the kitty's ability
Speaker 1: to remove sodium and helping blood vessels function properly. Challenging
Speaker 1: the common assumption that immune activity is always harmful in hypertension,
Speaker 1: our finding suggest that the immune system isn't necessarily working
Speaker 1: against the body and high blood pressure. Certain white blood
Speaker 1: cells appear to actually protect the body during salt sensitive hypertension.
Speaker 1: Number five, the immune system's kidney repair crew immune system
Speaker 1: may influence more than blood pressure. Another study in mice
Speaker 1: suggests it also plays a critical role in helping the
Speaker 1: kidneys recover after injury. Using advanced imaging and genetic tools,
Speaker 1: the researchers tract immune cells called macrofages and the mice
Speaker 1: is kidneys following a QTE kidney injury and found the
Speaker 1: cells appear to assume different jobs at different stages of recover.
Speaker 1: Early after injury, the cells moved in and clustered in
Speaker 1: an area of inflammation and damage. Later, they helped to
Speaker 1: clear away cellular debris and support the repair process while
Speaker 1: removing some of these cells before injury could be protective
Speaker 1: who are removing them During the recovery phase, slow healing
Speaker 1: and damage material lingered in the kidneys, increasing the risk
Speaker 1: of long term scarring. The kidneys are far more than
Speaker 1: passive filters. Across these five studies, the kidneys emerge as
Speaker 1: deeply woven into the body's communication networks shaping behavior, metabolism,
Speaker 1: blood pressure, and immune response. Although not yet settled science,
Speaker 1: taken together, these findings reflect a broader shift in how
Speaker 1: scientists increasingly see the kidneys as organs whose influence extends
Speaker 1: throughout the body, playing a far larger role in overall
Speaker 1: health than most people ever realized. There's a little peace
Speaker 1: on consultations. Hi everybody, and welcome. I just want to
Speaker 1: talk to you for a bit about consultation times. You
Speaker 1: may not be aware that that's pretty much where my
Speaker 1: training has been my entire career, sitting down and delving
Speaker 1: into health situations that an individual has so that you're
Speaker 1: able to make at least some common sense out of
Speaker 1: what's going on and make a plan for moving ahead.
Speaker 1: So many people get frustrated by the traditional medical model alopathy.
Speaker 1: Get a prescription, that's it. How often can they actually
Speaker 1: make such a substantial difference or change something in the
Speaker 1: physicality of you. So when you want to do a
Speaker 1: consultation time, what you need to do is give me
Speaker 1: a call at seven two seven nine one six four
Speaker 1: two one five, or go directly to my website d
Speaker 1: r L E NJB dot com. It's dr L E
Speaker 1: NJB dot com and right there you can schedule your
Speaker 1: own consultation time. You'll notice that there's a questionnaire to
Speaker 1: fill out that will help me ascertain what's going on
Speaker 1: with your particular situation. And again you can call of
Speaker 1: a message, we'll call you back and get your scheduled.
Speaker 1: It's seven two seven nine one six four two one five.
Speaker 1: God bless you folks, talk to you soon again. That
Speaker 1: number is seven two seven nine one six four two
Speaker 1: one five. Seem
