Day 1 :
President of Entirely Nourished LLC, USA
Time : 09:55-10:40
Michelle Routhenstein is the owner and president of Entirely Nourished LLC, a nutrition counseling and consulting private practice based in New York City. She is a Preventive Cardiology Dietitian, Registered Dietitian Nutritionist, and Certified Diabetes Educator. Mrs. Routhenstein graduated with a M.S. in Clinical Nutrition from NYU and completed her dietetic residency at NYU. She has over 10 years of experience counseling patients on chronic disease prevention and management. Mrs. Routhenstein, alongside a team of doctors and scientists, developed a risk assessment and telemedicine prevention program for individuals who are at high risk for cardiovascular disease based on modifiable lifestyle medicine factors.
Cardiovascular disease (CVD) is the global leading cause of death, with an average of 1 in 4 people dying from heart disease annually in the United States. The World Health Organization (WHO) estimates that 75% of deaths from CVD can be decreased by lifestyle management. One in three Americans have a risk factor for heart disease that can be prevented. Preventable risk factors include abnormal lipid panel, particularly small, dense LDL particles; being overweight or obese, especially when the weight is concentrated in the abdominal region; high blood pressure; uncontrolled diabetes; physical inactivity; smoking; and high stress and anger levels. The American Heart Association states that 99% of Americans need to improve their heart health. This lecture will focus on reviewing the latest research on food and nutrients that may protect the heart and prevent heart disease

Background: Oxidation reactions it is known that shorten the shelf life and cause damage to foods rich in fat, such as dairy products. One way to limit oxidation and increase the shelf life of fermented dairy products is to use natural antioxidants. The aim of this study was to examine the effect of adding pomegranate extracts in the antioxidant properties, rheological characteristics and the storage stability of the fermented product of kefir.
Method: The pomegranate juice (PGJ) and peel extracts (PGPE) (5%, 10% w/v) were added to kefir and the antioxidant properties were evaluated by using the methods of radical scavenging activity (DPPH) and ferric reducing antioxidant power activity (FRAP). Spectrophotometric and instrumental methods were used to determine the total phenols (TPs), pH values, viscosity and flow behavioral index values of enriched with pomegranate kefir samples. The same properties were tested when kefir samples stored at 4°C for 7, 14, 21 and 28days.
Results: The addition of PGJ and PGPE results in an increase in the antioxidant activity (DPPH, FRAP) and total phenol content (TPs) of kefir samples. Increasing the concentration of the added PGJ and PGPE, results in an increase in the TP content and the DPPH activity of kefir. As far as the storage time is concerned, the results showed an increase in the amount of TP at 7th day and a reduction in the DPPH activity in the 14th day of storage. In contrary to the DPPH method, the increase in storage time has resulted in a reduction in antioxidant activity by the FRAP method. The addition of PGJ and PGPE in kefir, results in a decrease in pH values while the pH of kefir samples increased during storage at 40C for 28days. The addition of PGJ and PGPE to kefir samples results to a decrease in viscosity and an increase in the flow behavior index. Increasing storage time results in increased flow behavior index of kefir samples.
Conclusion: The addition of PGJ and PGPE increased the antioxidant activity and total phenols of the kefir product and preserve its properties during the total storage time of 28 days at 4°C.
