Fruit Lowers Blood Pressure and also Risk for Diabetes
Eating fruits such as avocados, apples and also berries might sustain your metabolic wellness, reducing your threat of Type 2 diabetic issues and also sustaining healthy and balanced high blood pressure.
At the core of the problem, Type 2 diabetic issues is a feature of insulin resistance, which subsequently is a diet-induced problem. Obesity, hypertension and also high blood glucose are additionally indicators of metabolic disorder, a team of threat aspects that increase your threat of diabetic issues.1
Processed foods packed with added sugars, refined grains and also commercial refined omega-6 veggie oils are the key wrongdoers that set off insulin resistance, Type 2 diabetic issues and also excessive weight, and also while eliminating hazardous foods such as these is necessary, adding in healthy and balanced foods, like particular fruits, container be valuable.
Optimizing your nourishment can aid decrease your insulin degree, support your sugar degree and also enhance your total power. Fortunately, making tiny favorable nutritional modifications, consisting of consuming even more of particular healthy and balanced fruits, might help in reducing your threat of diabetic issues and also reduced your high blood pressure.
The Mighty Avocado Helps Lower Blood Sugar
Legend has it the very early name for avocados — “alligator pear” — originated from a very early English mispronunciation and also misconception.2 The name might have proceeded because the skin has a slightly reptilian look and also the fruit is formed like a pear. But regardless of the name or look, avocados are superfoods that might additionally aid decrease your blood glucose.
Paul Spagnuolo, Ph.D., and also a group at the University of Guelph in Ontario, Canada, disclosed that a substance called thing B, discovered just in avocados, can beneficially modify mobile procedures that boost the threat of diabetic issues.3,4 In Canada, 25% of people are overweight. This is a problem that boosts the threat of Type 2 diabetic issues. By contrast, the frequency of excessive weight in the U.S. was 42.4% in 2018.5
The group started the research study by feeding computer mice a high-fat diet regimen for 8 weeks, which caused excessive weight and also insulin resistance. Over the following 5 weeks, the computer mice were divided right into 2 teams. One team proceeded the high-fat diet regimen and also the various other team’s food was supplemented with avocatin B.6
At completion of the 5 weeks, the scientists discovered the computer mice that were treated with avocatin B had actually obtained considerably much less weight than the control team and also, much more significantly, had a greater insulin level of sensitivity.7
The group after that took place to check supplements in a human medical test in which they provided avocatin B as a nutritional supplement to individuals that were consuming a common Western diet regimen. They discovered weight decreases in the people and also no result on the kidney, liver or skeletal muscle mass from the supplement. While talking with Nutrition Insight, Spagnolo advised: 8
“We want to stress that the benefit of this molecule is in its ability to help regulate blood glucose. Reductions in weight are likely a secondary effect. We realize that this is a desirable feature for most, however, urge caution for weight loss as the sole indication.”
Spagnuolo additionally spoke to a press reporter from Yahoo! Life regarding the bioactive component, avocatin B. He thinks avocados are a healthy and balanced enhancement to the diet regimen for individuals with diabetic issues and also prediabetes, describing: 9
“When we discuss bioactives, consider it like the nutrients we receive from various other foods: we obtain Omega-3 fats from consuming fish and also Vitamin C from oranges. AvoB is a bioactive component in avocados, which can be a vital nutritional option for diabetics and also prediabetics.
When your metabolic process is functioning, whatever remains in equilibrium. You have perfect degrees of blood glucose, excellent cholesterol, blood pressure, etc. … Science tells us that blood sugar imbalances can have a profound and negative impact on our health.
They can impact our energy levels, concentration, mood, and much more. And for diabetics, unbalanced blood sugars could lead to even more serious health complications like heart attack and stroke.”
While the avocado is one of the healthiest foods, rich in monounsaturated fat, fiber, magnesium, potassium, vitamin K and carotenoids, there is also a dark side. Each avocado requires 70 liters (18.49 gallons) of water to produce, which means the fruit can be environmentally destructive.

High Flavanol Diet May Help Lower Blood Pressure
People with metabolic syndrome also have difficulty regulating their high blood pressure. In what researchers called the first-of-its-kind study in the U.K., scientists used objective measures for dietary intake across thousands of residents, using data for 25,618 people in Norfolk, U.K., and also compared the data against their blood pressure measurements.10
Most other studies look at links between nutrition and wellness but rely on the study participants’ self-reported data. In this analysis, the researchers measured the participants’ flavanol intake using nutritional biomarkers present in the blood. They then compared those against their blood pressure measurements.11
The data revealed blood pressure measurement differences between people with the highest 10% of flavanols as compared to the lowest 10% between 2 and 4 mmHg. The researchers wrote this was comparable to the difference measured when a person switched to a Mediterranean diet or the Dietary Approaches to Stop Hypertension (DASH) diet.
Nutritionist Gunter Kuhnle at the University of Reading led the study. He talked about the importance of how the data were collected and the implications for consistent dietary intake of foods with flavanols, saying: 12
“Previous studies of large populations have always relied on self-reported data to draw conclusions, but this is the first epidemiological study of this scale to objectively investigate the association between a specific bioactive compound and health. We are delighted to see that in our study, there was also a meaningful and significant association between flavanol consumption and lower blood pressure.
What this study gives us is an objective finding about the association between flavanols — found in tea and some fruits — and blood pressure. This research confirms the results from previous dietary intervention studies and shows that the same results can be achieved with a habitual diet rich in flavanols. In the British diet, the main sources are tea, cocoa, apples and berries.”
The subclass of flavanols measured in the study were flavan-3-ols,13 commonly found in tea, berries, apples and cocoa-based products.14 These same flavonoids have demonstrated benefits in other studies.15
Researchers have found those who drank tea consistently had a lower risk of all-cause mortality and were free of atherosclerotic cardiovascular disease for 1.41 years longer than those who did not drink tea.16 Of the tea tested, green tea was the most healthful. Green tea has also been linked with other health benefits that I discuss in “Tea Drinkers Shown To Be More Healthy.”
The High Cost of Diabetes
In 2011, the Centers for Disease Control and Prevention reported that diabetes affected 25.8 million people in the U.S.17 This was 18.8 million who were diagnosed and 7 million who were undiagnosed, representing 8.3% of the population. A short nine years later those numbers had jumped drastically higher.
The CDC currently reports 34.2 million people with diabetes, 26.9 million of which are diagnosed and 7.3 million are undiagnosed.18 The total represents 10.5% of the U.S. population. They also estimate the number of people with prediabetes who are over 18 years as 88 million people or 34.5% of the adult population.
In total, 45% of the U.S. population is affected by diabetes or prediabetes, which can lead to long-term complications including cardiovascular disease, nerve damage and Alzheimer’s disease.19
The combination of many individuals with diabetes and the number of complications associated with the condition contribute to the staggering financial costs of the disease. According to the American Diabetes Association, people with diabetes have 2.3 times more health care costs than those without diabetes.20
Annually, this totals $327 billion, which means 1 in every 7 health care dollars is spent on treating people for diabetes and its complications. The largest expenditures are on inpatient care, prescription medications, diabetes supplies and physician office visits. There are also indirect costs to the individuals and employers, including $26.9 billion lost in reduced productivity and $3.3 billion lost in absenteeism.
Address Mitochondrial Dysfunction and Insulin Sensitivity
At the center of the pathology behind diabetes is mitochondrial dysfunction. Eating a high-carbohydrate diet that bathes your mitochondria in glucose can suppress mitochondrial metabolism.21
As I’ve written before, your mitochondria are power producers inside most of your cells and are the primary sources of energy to keep your body functioning. Mitochondrial dysfunction is at the heart of several disease pathologies, including cardiovascular diseases22 and neurological dysfunction.23
While there is no easy answer, I believe the foundational first step to addressing metabolic defects responsible for mitochondrial dysfunction, Type 2 diabetes and obesity is to make food choices that boost mitochondrial health. I discussed this in detail in my book Fat for Fuel.
In my book I discussed the importance of metabolic flexibility and insulin sensitivity. Achieving this through nutritional ketosis helps to support your mitochondrial health. To reverse Type 2 diabetes, you need to recover insulin and leptin sensitivities.
The best way to address those metabolic conditions is through proper diet and exercise as I detail in my free nutritional plan. You’ll find further suggestions to optimize your health and improve your insulin sensitivity, including optimizing gut flora, monitoring fasting insulin degrees and also sleep requirements in “Diabetes Has Become One of the Most Expensive and Lethal Diseases in the World.”
As for fruit consumption, eating small amounts can be an excellent way to increase your intake of beneficial antioxidants, vitamins and also minerals. But moderation is key, especially if you have metabolic syndrome, high blood pressure and also/or Type 2 diabetes.
Because fruit contains fructose, it container increase your risk of insulin resistance if you eat large amounts. Examples of lower fructose fruits that are beneficial for most people include avocados, berries, kiwi and also citrus fruits.
