One-cup of frozen red raspberries has only 80 calories, is an excellent source of vitamin C, and provides nine grams of fiber (more fiber than any other berry). Like most berries, raspberries are a low-glycemic index food. Raspberries contain phytochemicals, such as ellagic acid, quercetin, gallic acid, cyanidins, pelargonidins, catechins, kaempferol and salicylic acid.

Animal and cellular studies examining how phytochemicals may work at the molecular level suggest that certain phytochemicals may help slow age-related declines. Age is the number one risk factor for many chronic diseases. Likewise, obesity is a major risk factor for chronic disease.  These latest animal studies examine two important areas of health where raspberry products may play a role in weight management and also support motor function.

OBESITY
An animal study conducted by researchers at Oregon State University found that when added to a high-fat, high-sucrose diet, raspberry products and raspberry phytochemicals were found to significantly decrease weight gain associated with a high-fat, high calorie diet. Raspberry juice and raspberry puree concentrates were provided at 10% of total energy (the equivalent of 200 calories in a 2,000 calorie diet), and a combination of ellagic acid and raspberry ketone were provided at 0.2% weight/weight.

In the study, 76 male mice were divided into the following diets:  a low-fat control group (10% calories from fat), a high-fat control group (45% calories from fat) and seven “high-fat treatment” groups that included a high-fat diet plus either raspberry juice concentrate, raspberry puree concentrate, raspberry fruit powder, raspberry seed extract, raspberry ketone and a combination of equal parts of ellagic acid and raspberry ketone.

“The addition of raspberry juice concentrate, raspberry puree concentrate and the combination of ellagic acid plus raspberry ketones to the high fat diet significantly reduced weight gain observed in the high-fat fed mice,” said Dr. Neil Shay, principal investigator. “In the case of the high-fat and raspberry juice concentrate diet, weight gain was reduced to a level that was statistically equivalent to the weight gain of the low-fat fed mice, despite the fact that all high-fat fed groups consumed the same amount of calories and more energy than the low-fat control group throughout the study.”

The researchers concluded that the intake of a reasonable level of some raspberry food products may influence some of the metabolic consequences of consuming a high-fat, high-calorie diet in the development of obesity in male mice.

“We hope that the findings from this study can help guide the design of future clinical trials,” said Dr. Shay.

MOTOR FUNCTION
Researchers from the Human Nutrition Research Center on Aging at Tufts University evaluated the effectiveness of a red raspberry-supplemented diet on age-sensitive measures of learning, memory and motor performance in older rats.

In this 10-week study, red raspberry supplementation was found to significantly improve motor skills. Specifically, compared to rats fed a standard well-balanced diet, rats fed a diet supplemented with freeze-dried raspberry extract performed better on tests which measured psychomotor coordination and balance, as well as tests that measure muscle tone, strength, and stamina.

“These results may have important implications for healthy aging,” said lead researcher Barbara Shukitt-Hale, PhD. “While further research in humans is necessary, animal model studies are helpful in identifying deficits associated with normal aging.”

Get smart about your heart

From regular checkups and reducing stress to eating well – including heart-healthy snacks like grapes – and exercising regularly, these simple steps can help boost your heart health.

Published

on

A crucial component of overall well-being, heart health can be a barometer for living a long, healthy and happy life. Because heart disease is the leading cause of death in the US, according to the Centers for Disease Control and Prevention, taking steps to reduce your controllable risk factors – including poor diet, stress and inactivity – can set you on the right path.

From regular checkups and reducing stress to eating well – including heart-healthy snacks like grapes – and exercising regularly, these simple steps can help boost your heart health.

Know Your Numbers
Knowing key health metrics such as blood pressure, cholesterol levels, blood sugar levels and body mass index can help you and your health care provider identify potential risks early. Schedule annual checkups and discuss any concerns you may have about your heart health. Early detection and risk factor management can reduce the likelihood of developing heart disease.

Eat More Fruits and Vegetables
Incorporating a variety of colorful fruits and vegetables into your diet can ensure you get a broad range of vitamins, minerals, fiber and antioxidants, all of which contribute to a healthy cardiovascular system. For example, leafy greens like spinach and kale are high in potassium, which helps manage blood pressure. Fresh grapes contain 7% of the daily recommended intake of potassium, are a good source of vitamin K and are also a natural source of beneficial antioxidants and other polyphenols, including flavonoids, that can help relax blood vessels and promote healthy circulation. Some studies also suggest grapes have a beneficial impact on blood lipids and more.

In fact, one study found women who consumed 1 1/4 cups of grapes every day benefited from reduced blood triglyceride levels, LDL cholesterol levels, inflammatory proteins and other markers of heart disease.

Bright, juicy and bursting with flavor, Grapes from California can be enjoyed by the handful or blended with rich bananas, tangy Greek yogurt and a hint of almond in The Great Grape-Acai Smoothie Bowl for a delicious blend of fruity flavors at breakfast, lunch or snack time – it not only tastes great, but supports a healthy heart. 

Get Moving
Regular physical activity is one of the most effective ways to improve heart health. Exercise strengthens the heart muscle, improves blood circulation and helps maintain a healthy weight. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, as recommended by the American Heart Association, such as walking, jogging or swimming with strength training exercises like lifting weights or using resistance bands mixed in to help reduce the risk of heart disease and improve overall cardiovascular health.

Manage Stress
Consider your stress level: chronic stress can negatively impact heart health, increasing blood pressure and other risk factors for heart disease. Techniques such as deep breathing, meditation, yoga and regular physical activity can help manage stress levels and maintain a healthy heart. Additionally, taking time to engage in hobbies, spending time with loved ones and ensuring adequate sleep are stress-reducing activities that improve overall well-being and heart health.

Eat your greens and skip the sugar spikes 

Cruciferous vegetables like broccoli and kale could help with the management of blood sugar levels, particularly for people at risk of type 2 diabetes and cardiovascular disease (CVD).  

Published

on

New research by Edith Cowan University (ECU) has found evidence that cruciferous vegetables like broccoli and kale could help with the management of blood sugar levels, particularly for people at risk of type 2 diabetes and cardiovascular disease (CVD).  

PhD student Ms Emma Connolly investigated whether cruciferous vegetable intake improved glycaemic control (blood sugar control) compared to root and squash vegetables in non-diabetic adults with elevated blood pressure. 

In a randomised, controlled, crossover trial, participants consumed four serves per day of either cruciferous vegetables (broccoli, cabbage, cauliflower, kale) or root and squash vegetables (carrot, potato, pumpkin, sweet potato) with lunch and dinner meals for two weeks. 

“Our participants wore glucose monitors throughout the study, so that we were able to measure blood sugar levels continuously throughout each two-week period,” Ms Connolly said. 

“We found that, when participants consumed the cruciferous vegetables, they had less variable blood sugar levels compared to when they consumed the root and squash vegetables. We also noted that these participants had a smaller spike in sugar levels after the meals. A central goal of blood sugar control, particularly for people with diabetes, is to smooth out spikes and reduce variability in blood sugar levels throughout the day. Stable blood sugar, with minimal peaks and less fluctuations is associated with better overall health and wellbeing.” 

Ms Connolly said further research is essential to fully understand the underlying mechanisms driving these findings, as well as to explore the broader clinical implications.  

“Continued investigation will be crucial to determine how these vegetables can be effectively incorporated into dietary recommendations for improved blood sugar regulation and overall health management,” she said. 

Poor glycaemic control is estimated to occur in 541 million individuals worldwide. Ms Connolly noted that dysregulated glucose control increases the risk of type 2 diabetes and subsequent CVD and has a substantial societal impact.  

The total cost attributed to type 2 diabetes with CVD is projected to exceed AUD$18.7 billion in Australia alone by 2031.  

“Less than 1 in 15 Australian adults meet vegetable intake recommendations. Even more concerning is that cruciferous vegetables are among the least consumed vegetables. Adding vegetables like broccoli, kale, bok choy, gai lan, and cabbage to your meals most days could make a big difference to your health,” Dr Lauren Blekkenhorst said.
