  Welcome to another episode of Morning Medical with Dr.

  I'm your host, Dr.

  Chi-Ming Chow.

  As always, we're here to bring you the latest in medical and health news from around the
• 0:12
  globe, with the help of artificial intelligence.
• 0:16
  Today, we'll be delving into dietary guidelines and their impact on the average American.
• 0:24
  Contrary to what some headlines might suggest, the newly released 2025-2030 Dietary Guidelines
• 0:31
  for Americans aren't drastically different from previous versions.
• 0:35
  These guidelines continue to emphasize limits on added sugars, sodium, and saturated fats,
• 0:41
  while promoting nutrient-dense foods as the backbone of a healthy diet.
• 0:46
  However, there are areas where scientific disagreement persists, such as the recommended
• 0:51
  amount and sources of protein, the consumption of full-fat dairy, and limits on alcohol.
• 0:57
  It's important to note that dietary guidelines have often been a subject of controversy.
• 1:03
  While these guidelines play a crucial role in shaping federal nutrition programs, they aren't
• 1:08
  typically found alongside cookbooks on the average American family's kitchen table.
• 1:12
  Many Americans are either unaware of these guidelines or find it challenging to meet the
• 1:16
  recommendations, especially when it comes to adequate consumption of fruits and vegetables.
• 1:21
  It's overly simplistic to blame the rising rates of obesity and diabetes in the U.S.
• 1:27
  on potentially flawed guidelines alone.
• 1:29
  It's equally unrealistic to expect the latest guidelines will single-handedly reverse these
• 1:34
  chronic conditions.
• 1:36
  Healthy eating involves more than just personal responsibility.
• 1:41
  Individual decisions are influenced by broader policies, systems, and environments that can
• 1:47
  either facilitate or hinder healthy choices.
• 1:50
  If we aim to combat diet-related epidemics, we need to focus on advancing public policies that
• 1:57
  promote health, especially in areas where scientific consensus exists.
• 2:02
  One key area for policy action is the food supply.
• 2:06
  The Food and Drug Administration, or FDA, should finalize its guidance for industry,
• 2:13
  which sets voluntary sodium reduction targets.
• 2:17
  By doing so, sodium intake could decrease over three years, aligning more closely with the
• 2:23
  upper limit of 2,300 milligrams per day recommended by nutrition guidelines.
• 2:30
  The FDA should also encourage public commitments from companies in high-sodium food
• 2:34
  categories and set industry targets for added sugars while monitoring artificial sweetener
• 2:39
  use.
• 2:41
  Another crucial aspect is food accessibility.
• 2:45
  The Treasury Department and the Department of Agriculture should launch initiatives to
• 2:50
  incentivize new grocery stores and farmers' markets in food deserts.
• 2:56
  Local governments could also revise zoning policies to enable the establishment of healthy
• 3:02
  food access points while limiting fast-food density, often associated with processed foods.
• 3:10
  Additionally, federal nutrition programs like the Supplemental Nutrition Assistance Program,
• 3:16
  or SNAP, could implement waivers that incentivize healthy foods and discourage
• 3:21
  unhealthy ones.
• 3:24
  Lastly, food marketing plays a significant role.
• 3:27
  The Department of Health and Human Services and the Federal Trade Commission should work to
• 3:31
  limit the marketing of unhealthy foods to children.
• 3:35
  Learning from other countries, the U.S.
• 3:37
  can adopt effective strategies to reduce children's exposure to unhealthy food
• 3:42
  advertising.
• 3:44
  The FDA should also finalize rules for front-of-package nutritional labels to help
• 3:50
  consumers understand the nutritional content of packaged goods better.
• 3:55
  Ultimately, policymakers have a tremendous opportunity to impact diet-related chronic
• 4:01
  conditions.
• 4:02
  While guidelines are helpful, meaningful action is needed to make America a healthier nation.
• 4:08
  This requires a concerted effort across various levels of government and industry to implement
• 4:13
  policies that make healthy choices more accessible and appealing.
• 4:19
  Some surveys indicate that around seventy-five percent of adults in the United States have
• 4:23
  taken dietary supplements at some point, while federal survey data shows that fifty-eight
• 4:28
  percent have used one within the past thirty days.
• 4:33
  However, experts caution that certain groups, such as individuals with diabetes, should be
• 4:38
  particularly careful when considering supplement use.
• 4:41
  Dietary supplements come in various forms, including vitamins, minerals, herbs, amino
• 4:47
  acids, and probiotics.
• 4:49
  They're designed to fill nutrient gaps and support overall wellness, with some targeting
• 4:54
  specific functions like immune support, muscle recovery, and bone health.
• 5:00
  Yet, it's important to note that unlike prescription drugs and over-the-counter
• 5:04
  medications, supplements are not typically approved by the Food and Drug Administration
• 5:09
  before they are marketed.
• 5:12
  The Food and Drug Administration does regulate them, but only acts against unsafe or
• 5:17
  misbranded products.
• 5:19
  For people with diabetes, certain supplements could pose serious health risks as they might
• 5:24
  affect blood glucose levels or interact with medications.
• 5:28
  St.
• 5:28
  John's Wort, for instance, is often used as a natural remedy for mild to moderate depression,
• 5:34
  but it can interfere with diabetes medications, making blood sugar management more challenging.
• 5:39
  Dawn Menning, a registered dietitian and certified diabetes care and education
• 5:44
  specialist, advises against its use for diabetic individuals.
• 5:49
  Chromium is another supplement often marketed for its potential to improve blood sugar
• 5:55
  regulation in type two diabetes.
• 5:58
  However, the evidence supporting its effectiveness is mixed.
• 6:01
  Taking chromium with insulin or other diabetes medications may increase the risk of
• 6:06
  hypoglycemia, which can lead to dizziness, fatigue, and fainting.
• 6:11
  Bitter melon supplements are sometimes used to help reduce blood sugar levels in people with
• 6:16
  diabetes.
• 6:17
  They contain compounds like polypeptide-p, which may act similarly to insulin.
• 6:22
  However, when combined with diabetes medications, they could increase the risk of
• 6:27
  hypoglycemia.
• 6:29
  Niacin, or vitamin B3, is sometimes used to manage cholesterol levels.
• 6:34
  However, in individuals with diabetes, it may raise blood sugar levels, increasing the risk
• 6:40
  of hyperglycemia.
• 6:42
  Michelle Routhenstein, a preventive cardiology dietitian, cautions against high-dose niacin
• 6:47
  supplements as they can make it difficult to maintain optimal A1c levels.
• 6:53
  Ginseng, particularly Asian ginseng, is known for boosting energy, focus, and immune system
• 6:59
  health.
• 7:00
  While it may improve certain cardiometabolic factors for those with prediabetes and
• 7:03
  diabetes, it can also lower blood sugar levels when combined with diabetes medications, posing
• 7:09
  a risk of hypoglycemia.
• 7:10
  Β-carotene is primarily used as an antioxidant and a source of vitamin A.
• 7:16
  However, the American Diabetes Association advises against its use for people with
• 7:22
  diabetes due to its association with increased lung cancer and cardiovascular mortality risks.
• 7:29
  Cinnamon, particularly Cassia cinnamon, is often promoted for managing diabetes and weight
• 7:35
  loss.
• 7:36
  While some research suggests it can help reduce blood sugar and lower insulin resistance,
• 7:41
  consuming large amounts can enhance the effects of diabetes medications and cause blood sugar
• 7:47
  levels to fall too low.
• 7:49
  Additionally, cinnamon contains coumarin, which can cause liver damage if consumed in large
• 7:54
  quantities.
• 7:56
  Aloe vera, often taken orally for diabetes, weight loss, and inflammatory bowel disease,
• 8:02
  can also cause blood sugar levels to dip dangerously when paired with diabetes
• 8:07
  medications, increasing the risk of hypoglycemia.
• 8:11
  The primary concern with most supplements is not necessarily direct harm but rather the lack
• 8:16
  of regulatory oversight.
• 8:18
  The American Diabetes Standards of Care state that without an underlying deficiency, there
• 8:24
  are no benefits from herbal or nonherbal supplementation for people with diabetes.
• 8:30
  The American Association of Clinical Endocrinology advises caution with all
• 8:35
  unregulated nutritional supplements due to their inconsistent composition, quality, and
• 8:40
  potential for harm.
• 8:43
  Experts recommend speaking with a healthcare provider before starting any supplement to
• 8:47
  understand its potential impact on blood sugar levels, medications, or overall diabetes
• 8:52
  management.
• 8:53
  It's essential to approach supplement use with caution, particularly for individuals managing
• 8:58
  chronic conditions like diabetes.
• 9:02
  Nurses at a major New York hospital system have approved a new contract, effectively ending a
• 9:08
  significant nursing strike that lasted over a month.
• 9:12
  More than four thousand nurses from the privately-run NewYork-Presbyterian system went
• 9:18
  on strike on January twelfth and are now set to return to work in the upcoming week.
• 9:23
  The New York State Nurses Association, the union representing the nurses, reported that
• 9:29
  ninety-three percent of its members at NewYork-Presbyterian voted to ratify the
• 9:34
  three-year contract.
• 9:36
  The strike at NewYork-Presbyterian was part of a larger movement, as nurses from two other
• 9:41
  prominent private hospital systems, Montefiore and Mount Sinai, had already resolved their
• 9:47
  disputes earlier this month by reaching contract agreements with the same union.
• 9:53
  Nancy Hagans, the union president, expressed satisfaction with the outcomes, stating, "We
• 10:00
  are so happy with the wins we achieved, and now the fight to enforce these contracts and hold
• 10:05
  our employers accountable begins."
• 10:08
  NewYork-Presbyterian expressed anticipation for the return of its nurses, emphasizing that the
• 10:14
  new contract "reflects our respect for our nurses and the critical role they play as part
• 10:19
  of our exceptional care teams." The tentative deal, reached on Friday, was voted on by union
• 10:25
  members on Friday and Saturday, making it official over the weekend.
• 10:31
  The new contract includes several key provisions such as staffing improvements,
• 10:34
  raises exceeding twelve percent over three years, and safeguards regarding the use of
• 10:39
  artificial intelligence.
• 10:40
  The union indicated that initially, the strike involved approximately fifteen thousand nurses
• 10:46
  across Montefiore, Mount Sinai, and NewYork-Presbyterian, although it affected only
• 10:50
  specific facilities within these systems and did not involve any city-run hospitals.
• 10:57
  Throughout the strike, the hospitals hired thousands of temporary nurses, transferred some
• 11:01
  patients, and canceled certain procedures.
• 11:04
  Despite these disruptions, the hospitals maintained that they continued to deliver care
• 11:09
  smoothly, including complex surgeries.
• 11:12
  However, some vulnerable patients and their families noted that routine tasks took longer
• 11:17
  to complete.
• 11:19
  The striking nurses highlighted issues such as unmanageable workloads and accused the
• 11:24
  hospitals of attempting to reduce health benefits.
• 11:27
  Meanwhile, the hospitals contested these claims, arguing that the union’s demands were
• 11:32
  excessive.
• 11:33
  It is worth noting that nurses at some Mount Sinai and Montefiore hospitals also went on
• 11:39
  strike in 2023, though that particular strike concluded within three days.
• 11:46
  Our final topic today is about the surprising link between oral health and a reduced risk of
• 11:51
  dementia, as dental health experts have highlighted.
• 11:55
  At the recent American Association for the Advancement of Science conference, researchers
• 12:00
  presented compelling evidence that good oral hygiene might be more significant than just a
• 12:05
  bright smile.
• 12:07
  It could actually contribute to a longer, healthier life, reducing the risk of serious
• 12:12
  conditions like Alzheimer’s disease and rheumatoid arthritis.
• 12:17
  The discussion, titled "The Mouth as a Gateway to Overall Health," shed light on how the mouth
• 12:22
  is not an isolated part of our body but deeply interconnected with our overall health.
• 12:28
  Professor Alpdogan Kantarci from the University of Minnesota’s School of Dentistry shared
• 12:34
  insights that maintaining dental health might reduce the risk of more than fifty systemic
• 12:39
  conditions.
• 12:40
  This connection underscores the importance of considering oral health as a critical component
• 12:45
  of overall healthcare.
• 12:48
  One of the key points discussed was how gum disease, such as periodontitis, leads to
• 12:53
  ongoing inflammation and can increase the risk of cognitive issues.
• 12:58
  This inflammation does not stay confined within the mouth but can affect other parts of the
• 13:03
  body, including the brain, potentially leading to conditions like dementia.
• 13:08
  The researchers emphasized that taking care of your teeth can lead to better cognitive
• 13:12
  responses, especially in those with mild or moderate diseases.
• 13:17
  A notable study from Tufts University School of Dental Medicine, published in The Lancet Health
• 13:22
  Longevity, highlighted that oral health should be an integral part of the healthcare system,
• 13:27
  especially as we age.
• 13:29
  The authors pointed out that oral health conditions could be potential risk factors for
• 13:34
  physical frailty or functional disability, thus affecting overall well-being and longevity.
• 13:40
  Dr.
• 13:41
  Michael J.
• 13:42
  Wei, a cosmetic and restorative dentist in New York City, emphasized the preventive health
• 13:48
  benefits of brushing your teeth more frequently.
• 13:51
  He explained that brushing three times a day can help control the bacterial biofilm
• 13:57
  responsible for gum disease and chronic inflammation.
• 14:00
  This practice not only supports oral health but also contributes to healthier aging by reducing
• 14:06
  the risk of systemic diseases.
• 14:09
  However, it's essential to brush properly to avoid complications.
• 14:14
  Brushing too aggressively or using a hard-bristled toothbrush can lead to enamel
• 14:19
  wear, gum recession, and tooth sensitivity.
• 14:23
  Experts recommend using a soft-bristled or electric toothbrush with gentle, controlled
• 14:28
  movements.
• 14:30
  This approach helps maintain optimal oral health without causing damage.
• 14:35
  Dr.
• 14:36
  Richard Lipari, a cosmetic and general dentist, advises brushing teeth twice a day for two
• 14:41
  minutes with gentle pressure.
• 14:43
  While a third brushing session can be beneficial, it should be done correctly to
• 14:47
  massage the teeth and gums rather than scrub them.
• 14:51
  Regular dental check-ups are also crucial to ensure proper oral care and address any signs
• 14:56
  of gum recession or enamel wear.
• 14:58
  As we wrap up today's episode, remember that maintaining good oral hygiene is more than just
• 15:04
  a cosmetic concern.
• 15:06
  It plays a vital role in our overall health, potentially reducing the risk of serious
• 15:11
  conditions like dementia.
• 15:12
  By incorporating proper dental care into our daily routines, we can support our long-term
• 15:18
  well-being.
• 15:19
