Maternal Mediterranean Diet May Relate to Children’s Weight Later in Life

Childhood obesity is a rising public health concern and a strong predictor of obesity later in life. Previous studies have discovered that mothers’ diets during pregnancy can potentially impact children’s weight and their risks of developing obesity. This study evaluated how mothers’ dietary patterns during pregnancy affect their children’s BMI (body mass index). A total of 1,459 women participated in the study and completed a questionnaire about the food they ate during pregnancy. Their children were followed up for 15 years to measure their weight and height change. The findings showed that children whose mothers had closely followed the Mediterranean diet during pregnancy are more likely to grow faster and have lower BMI than their peers during childhood. However, the researchers cautioned that differences in breastfeeding might partly explain the BMI differences across the groups. Thus, more studies are needed.

Mediterranean Diet Linked with Slower Prostate Cancer Progression, Better Survival

Many patients diagnosed with prostate cancer don’t need immediate intervention, so strictly monitoring the disease progression is critical. This study collected data from 410 men diagnosed with prostate cancer and measured how closely they were following the Mediterranean Diet. After 36 months of follow-up, those most closely following a Mediterranean diet were less likely to have significant disease progression, and were more likely to have a better rate of survival.

Mediterranean Diet Linked with 20% Lower Risk of Dementia

Dementia is an age-related disease causing memory loss and confusion, and over 50 million people suffer from dementia globally. Because there is currently no effective treatment for it, prevention is pivotal. To investigate whether the Mediterranean Diet has a protective effect on dementia, the researchers studied 16,160 middle-aged adults and followed them for over 20 years. Among all the participants, 459 were diagnosed with dementia. When comparing the dietary patterns between those with and without dementia, the researchers found that those most closely following the  Mediterranean diet,  were 20% less likely to develop dementia. However, the results were not statistically significant when looking at Alzheimer’s dementia.

Mediterranean Diet Linked with Healthy Gut Microbiota, Possible Lower Risk of Alzheimer’s

There are over 100 trillion microorganisms in the gut, which are thought to play a significant role in various aspects of overall health. In this review article, researchers suggest that the connection between the brain and gut may be associated with the development of Alzheimer’s disease because the gut microbiota may induce inflammation throughout the body, potentially provoking cognitive impairment. Recent studies have found that the composition of the gut microbiome significantly differs between those with and without Alzheimer’s disease. Diet also has a strong impact on the gut microbiome, hence affecting the risk of developing Alzheimer’s disease. In particular, following a Mediterranean diet is associated with a slower cognitive degeneration. On the other hand, the Western diet which contains high added sugar, processed meat, refined grains, and saturated fats is associated with greater inflammation.

Plant Based Diets Can Lower Blood Pressure

Studies have shown that plant-based diets can help lower blood pressure, but researchers wonder how strict you must be with your vegetarian diet to see results. A systematic review of 41 clinical trials was performed to see how different plant-based diets, including some with low levels of animal products (the Mediterranean, Vegan, Nordic, high-fiber, and high-fruit and vegetable diets) impacted blood pressure. The results showed that even plant-based diet with limited animal products can be effective in reducing high pressure, indicating that even small steps to improve health can make a measurable difference.

Mediterranean Diet Linked to Lower Risk of Parkinson’s Disease

Parkinson’s disease is one of the most common progressive nervous system disorders, and previous studies indicate a potential link between diet and the risk of Parkinson’s disease. In this study, 49,261 middle-aged Swedish women were followed up for an average of 10 years to track their eating habits and whether or not they were diagnosed with Parkinson’s. The researchers found that those most closely following a Mediterranean diet had a significantly lower risk of being diagnosed with Parkinson’s Disease, especially among women aged 65 years or older.

Mediterranean Diet Linked with Better Thyroid Health

Our thyroids act as internal thermostats providing our bodies with hormones that help balance our heart, muscle, and digestive function, brain development, and bone maintenance. In this study, researchers analyzed the eating habits and health of 200 people, about half with Hashimoto’s Thyroiditis (an autoimmune disease that attacks the thyroid) and half without. Those most closely following a Mediterranean diet were less likely to have Hashimoto’s Thyroiditis. Eating more animal foods (like meat) and fewer plant foods (like vegetables) was also linked with Hashimoto’s Thyroiditis.  However, more research is needed on how diet might impact autoimmune and thyroid health.

Mediterranean Diet Linked with Better Brain Health in Aging

A growing body of research demonstrates the Mediterranean diet’s relationship with healthy aging. This British study focused on 511 individuals whose average age was 79 years old. The scientists collected data on eating habits and brain health from the participants. They found that those who more closely follow a Mediterranean diet are more likely  to have overall better cognitive function, including better memory, visuospatial ability, and verbal ability. Furthermore, the study found that eating more  green leafy vegetables and lessmeat may be linked withbetter cognitive performance.

Mediterranean Diet Is Associated with Lower Risk of Type 2 Diabetes

The Mediterranean diet is linked with a lower risk of diabetes, and researchers want to learn more about the mechanisms behind this protective effect. This study followed up a group of 25,317 middle-aged women without diabetes for approximately 20 years. The results indicated that those who strictly follow the Mediterranean diet tend to have a 30% lower risk of developing type 2 diabetes compared to those who don’t follow a Mediterranean diet. The lower risk of diabetes could be partially explained by better insulin resistance, lower inflammation, and lower cholesterol in the women who followed a Mediterranean diet, and the results were especially strong in people who were overweight at the beginning of the study.

Mediterranean Diet Linked with Longer Lives

The secret to longer life just might be in your kitchen. A large study of 5,094 Italian men was conducted over a seven-year period to see how their daily diets and lifestyle habits affected mortality rates. Those most closely following the Mediterranean diet were less likely to die over the study period. Additionally, the researchers also found a significant relationship between lower death risk and eating higher amounts of vegetables, proteins, fats, starch, folic acid, and monounsaturated fats from plant-based sources (mostly from olive oil). On the other hand, animal fats and sugar were linked with a greater risk of death over the study period.

Mediterranean Diet Linked with Healthier Gut Microbiome in Aging

Some of the worlds healthiest, longest lived people follow a Mediterranean diet, so researchers wonder about the mechanism behind its link with healthy aging. In this study, researchers analyzed the gut microbiome of 612 older European adults before starting a Mediterranean diet, and then after 1 year of following a Mediterranean diet. Those who followed the Mediterranean diet most closely had significant differences in their gut microbiome, including microbes associated with lower risk of frailty, better brain function, and lower inflammation.

Healthy Lifestyle (Including Mediterranean Diet) Linked with Lower Risk of Alzheimer's

Eating a nutritious diet is one of the many daily lifestyle choices that can have an impact on our health, especially as we age. Researchers followed 2,765 adults in the Chicago area for over 5 years to see if their lifestyle choices were related to their risk of Alzheimer’s dementia. They specifically looked for these 5 healthy lifestyle factors: 1) not smoking, 2) at least 150 minutes per week of exercise, 3) low to moderate alcohol consumption, 4) following a Mediterranean-inspired healthy diet, and 5) participating in late-life “cognitive activities” like reading, crafting, playing games, and socializing. Compared with adults following 0 or 1 healthy lifestyle factor, the risk of Alzheimer’s dementia was 37% lower in those following 2 or 3 healthy lifestyle factors, and 60% lower in those following 4 or 5 healthy lifestyle factors.
