MedicalResearch.com: What is the background for this study?
Response: There is clear evidence from the literature that sodium reduction or potassium supplementation can reduce blood pressure. Reduced blood pressure can also lead to a risk reduction for cardiovascular diseases.
Salt substitute is a reduced sodium added potassium product combined those effects. Previous research of salt substitute focus on the blood pressure outcome. There is no evidence if salt substitute can reduce the risk of cardiovascular diseases or pre-mature death. This study provided a definitive evidence for this unaddressed question.

MedicalResearch.com: What is the background for this study?
Response: Diet is an important determinant of cardiovascular disease, and several studies have shown an association between high dairy and milk consumption with cardio-metabolic risk factors.
Especially high fat dairy products can increase the risk of high cholesterol and cardiovascular disease by increasing the intakes of saturated fat and dietary cholesterol.
However, milk is also a rich source of calcium and other nutrients, and evidence from randomized controlled trials has been inconsistent with respect to the role milk may have in cardiovascular health

MedicalResearch.com: What is the background for this study? What are its benefits?
Response: DHA is an omega-3 fatty acid. Good food sources include some types of seafood (e.g., salmon, tuna, trout) and chicken eggs. Persons in the USA and in much of the developing world consume little dietary DHA. DHA supplements in pregnancy have been linked to lower risk of preterm birth for 20 years, especially early preterm births (<34 weeks gestation). For about 10 years, prenatal supplements with about 200 mg DHA have been readily available in the USA, however, no study has asked if this amount of DHA is optimal to reduce early preterm birth. Participants were given a supplement of 1000 mg or 200 mg DHA beginning before 20 weeks gestation using an adaptive randomization that periodically assigned more participants to the group with the fewest early preterm births.

MedicalResearch.com: What is the background for this study?
Response: Early-onset colorectal cancer (EO-CRC, age <50 years at diagnosis) is rapidly rising in the US since the mid-1980s, with an unclear understanding of its etiology and contributors to the rise. Sugar-sweetened beverages (SSBs) exert adverse metabolic repercussions throughout the life course, including insulin resistance and inflammation. Higher SSB intake can induce obesity, which has been linked to risk of EO-CRC. A recent experimental study also suggests that high fructose corn syrup, a primary sweetener in SSBs, may promote colon tumor growth, independent of metabolic dysregulation. In the US, SSB consumption has dramatically increased during the 2nd half of the 20th century, and adolescents and young adults have been the heaviest SSB drinkers across all age groups. Thus, we expect SSBs may be an emerging risk factor for EO-CRC and likely contribute to the rising incidence of EO-CRC.

MedicalResearch.com: What is the background for this study?
Response: Food supplies in recent decades have been dominated by heavily processed, ready-to-eat products. Essentially, 75% of all world food sales are of processed foods. Over the past 30 years, children’s ultra-processed food intake has increased markedly, with 50% of the children in the US consuming these foods. Only in the US does UPF comprise 58% of energy intake, of which 90% is derived from added sugars. This reflects children’s excessive consumption of food and drink that are high in fat and refined sugars but do not provide appropriate levels of the proteins, vitamins and minerals required for growth.
The negative health outcomes of excessive consumption of Ultra-processed food are well known, include obesity, metabolic syndrome and diabetes, and considered as the current world epidemic; the fact that children, during their postnatal development period (birth to adolescent), are the target of the Ultra-processed food industry is very disturbing in terms of public health. Bone development and growth are the characteristic phenomena of the childhood period. Yet, in spite of the huge importance of nutrition to bone development, the impact of Ultra-processed food consumption on skeleton development during childhood has never been studied directly, and this was the purpose of our study.
To this end, we used young rats which are an excellent pre-clinical model for growth and fed them with either the recommended diet for their age or a diet comprised of a typical Ultra-processed meal (a roll, hamburger, tomatoes, lettuce, ketchup and French fries) and a caloric soft drink.

MedicalResearch.com: What is the background for this study?
Response: Previous studies have linked greater consumption of red and processed meat to poorer clinical cardiovascular outcomes, for example, higher risk of having a heart attack or of dying from heart disease. However, the biological mechanisms underlying these relationships are not well understood. Furthermore, the impact of meat intake on more direct measures of heart health, such as, structure and function of the heart and blood vessels, has not been previously studied in large cohorts. Examining how meat intake may influence different aspects of cardiovascular health can help us better understand its health effects.
The first step that you should take to finding inner peace is to practice yoga and meditation regularly. Yoga and meditation can give you the chance to slow down and reflect, as well as to clear your mind of the worries and negative thoughts that are concerning you. Not only this, but deep breathing is also an important aspect of both yoga and meditation as this can help you to ground yourself and to reconnect with the world around you.

Response: The literature suggests that sugars contribute to the incidence of breast cancer, but few exists on the prognosis after a breast cancer diagnosis.
MedicalResearch.com: What are the main findings?
Response: Compared to breast cancer patients who never or rarely drank non-diet soda, those who reported drinking non-diet soda five times or more per week had a 62% higher likelihood of dying from any causes, and were 85% more likely to die from breast cancer specifically.

MedicalResearch.com: What is the background for this study?
Response: Cardiovascular disease (CVD) has been the leading cause of morbidity and mortality globally. Prevalence of CVD among US population is approximately 7% which places huge burden on our healthcare systems. And prevalence of CVD is as high as 28% among veterans at the VA healthcare system as veteran users are primarily older male with more histories of comorbidities. Most CVD risk factors including lipids and blood pressure can be controlled by lifestyle modifications, such as diet.
Chocolate is among dietary factors that play a role in modulating CVD risk factors is widely consumed in the US (~2.8 billion pounds annually. Although previous studies have reported beneficial effects of chocolate and/or cacao products (rich in flavonoids) on lipids, glucose metabolism and risk of diabetes, and lipids, little is known about the association of chocolate intake with coronary artery disease (CAD) among US veterans. Thus, sought to test the hypothesis that chocolate consumption is associated with a lower risk of CAD among xxx US veterans enrolled in the Million Veteran Program.

MedicalResearch.com: What is the background for this study?
Response: To date, pharmacology therapies done to slow down or halt Alzheimer's disease have been inconclusive. Lifestyle interventions like changes in diet and activity are also mixed but do show some promise. Dietary clinical trials or self-reported diet have tended to focus on groups of foods such as the Mediterranean or MIND diet. To build from this excellent work, we were curious if we could pinpoint specific foods that were correlated with changes in fluid intelligence over time. Fluid intelligence represents our ability to creatively use existing knowledge, working memory, and other components of "thinking flexibly."
Further, we tested if these patterns of association differed based on genetic risk. In this case, genetic risk was defined as having a family history of Alzheimer's disease or having 1-2 "bad" copies of the Apolipoprotein E (APOE) gene, which is the strongest genetic risk factor for Alzheimer's disease.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Omega-3 fatty acids are incorporated into the phospholipids of cellular membranes, including cardiac contractile cells, and have a wide range of demonstrated physiological effects. Several potential mechanisms have been investigated, including antiarrhythmic, anti-inflammatory, and endothelial.
Omega-3 fatty acids lower heart rate and improve heart rate variability, both associated with lower sudden cardiac death risk, one of the complications that may occur after a myocardial infarction.
Increased omega-3 fatty acids also enhance arterial elasticity by increasing endothelium-derived vasodilators, which is associated with blood pressure–lowering effects.
They also have a cardioprotective effect on platelet-monocyte aggregation, and lower triglyceride levels.

MedicalResearch.com: What is the background for this study?
Response: We know from previous research that children who see food advertisements eat significantly more calories than children who see non-food advertisements. Those studies led the World Health Organization and National Academy of Medicine to issue reports declaring that exposure to food advertising is a major driver of childhood obesity.
What we don’t know is how frequently unhealthy food and beverage brands are appearing in YouTube videos posted by Kid Influencers. Kid influences are children whose parents film videos of the child playing with toys, unwrapping presents, eating food, or engaging in other family-friendly activities. The parents then post the videos to YouTube for other children and parents to view for entertainment.

MedicalResearch.com: What is the background for this study?
Response: During the COVID-19 pandemic, food insecurity is expected to rise given economic uncertainty and job losses. Vulnerable and marginalized populations are disproportionately affected by both COVID-19 and food insecurity.
MedicalResearch.com: What are the main findings?
Response: In this perspective, we argue that food insecurity and COVID-19 can exacerbate one another via bidirectional links. Experiencing food insecurity can lead to nutritional deficiencies and weakened host defenses, increasing susceptibility to COVID-19 infection. Food insecurity is also associated with chronic medical conditions which may lead to a higher risk of severe COVID-19 illness.
Conversely, people with COVID-19 may not be able to work, generate income, or procure food while quarantined, which may worsen food insecurity.
