Whey Protein Benefits: Muscle Growth, mTOR, IGF-1 & Myostatin | Kidney Stones & Macular Degeneration
What are the real benefits of whey protein for muscle growth, healthy aging and muscle protein synthesis? On this episode of Ask the Doctor, Dr. Michael Lange and Roger P. Schulman discuss whey protein, mTOR, IGF-1, myostatin, collagen peptides, cholesterol, kidney stones, oxalates, macular degeneration and nutritional strategies for maintaining muscle and eye health.
🥛 WHEY PROTEIN & MUSCLE GROWTH
Dr. Michael Lange discusses the newly released Fortifeye Super Protein, made with grass-fed, non-denatured whey protein concentrate and an all-new delicious vanilla flavor.
Whey is considered one of the highest-quality proteins for stimulating muscle protein synthesis (MPS) because it is rapidly digested and naturally rich in essential amino acids, particularly leucine.
The doctors explain how whey protein and its amino acids can influence important pathways involved in muscle metabolism, including:
• Muscle protein synthesis
• mTOR signaling
• IGF-1 signaling
• Myostatin-related pathways
• Muscle recovery
• Maintenance of lean muscle mass
• Healthy aging and sarcopenia prevention
The discussion also explains why adequate high-quality protein becomes increasingly important as we age, during periods of calorie restriction and for people trying to maintain muscle while losing weight.
🔬 WHEY + COLLAGEN PEPTIDES
Roger P. Schulman discusses newer research involving whey protein and cholesterol/metabolic markers in overweight adults under age 50, along with research examining the potential advantages of combining whey protein with collagen peptides.
Dr. Lange also discusses combining Fortifeye Fit Protein with Fortifeye Super Protein as part of a comprehensive protein and fitness nutrition strategy.
🪨 OXALATES & KIDNEY STONES
Can healthy foods contribute to kidney stones in susceptible people?
The doctors discuss oxalates and calcium-oxalate kidney stones, including several foods that can be extremely high in oxalates.
People with a history of calcium-oxalate kidney stones may be advised to limit foods such as:
• Spinach
• Almonds
• Beets
They also discuss why hydration and an individualized nutritional strategy are important for kidney-stone prevention.
👁️ MACULAR DEGENERATION, DIET & VITAMINS
Dr. Lange discusses age-related macular degeneration (AMD) and how diet and targeted nutrition can support macular and retinal health.
Learn about foods and nutrients associated with healthy vision and why Dr. Lange recommends Fortifeye Next Gen Macular Defense as part of his nutritional approach for appropriate patients with or at risk for macular degeneration.
🌱 ORGANIC BLUE GREEN SUPERFOOD
The show also features Fortifeye Organic Blue Green Superfood and discusses a special three-jar bundle discount.
☎️ BELL’S PALSY CALL
Dr. Lange takes a call from a potential patient regarding Bell’s palsy and discusses evaluation, treatment considerations and the importance of appropriate medical and eye care.
This episode of Ask the Doctor covers some of today’s most interesting topics in whey protein, muscle growth, longevity, nutrition and eye health.
