What You'll Learn
Diet drinks and weight gain
While diet drinks are marketed as a healthier alternative to sugary drinks, they may not be as harmless as they seem, especially if you're drinking several servings per day. Diet drinks are associated with an increased risk of type 2 diabetes, and people with type 2 diabetes who consume artificial sweeteners are more likely to develop insulin resistance.
Research has found that long-term consumption of diet drinks may affect overall heart health. A 2017 review in the Canadian Medical Association Journal found that participants who consumed artificial sweeteners had higher rates of obesity, high blood pressure, metabolic syndrome, type 2 diabetes, and heart problems. However, the exact role played by diet drinks is unclear, and more research is needed to confirm these findings.
The artificial sweeteners found in diet drinks may also negatively affect your gut microbiome, which plays a crucial role in immune function, nutrient absorption, and heart health. For example, aspartame, a common sweetener, has been found to decrease the production of short-chain fatty acids, which are important for preventing inflammatory diseases and regulating body weight.
It is worth noting that the relationship between diet drinks, artificial sweeteners, and blood pressure is complex. While some studies suggest a link between diet drinks and increased blood pressure, the evidence is mixed, and the underlying reasons are not fully understood.
To maintain a healthy weight and lower the risk of high blood pressure, it is recommended to adopt a balanced diet that includes plant-based foods, whole grains, and healthy fats, while reducing the consumption of processed foods, sugary snacks, and drinks high in salt and caffeine.

Artificial sweeteners and health
Artificial sweeteners are a common ingredient in many diet drinks, and their impact on health has been the subject of much research. While diet drinks are often marketed as healthier alternatives to sugary drinks, their effect on overall health is complex and not yet fully understood.
Some studies have suggested that long-term consumption of artificial sweeteners may negatively impact heart health. For example, a research review published in the Canadian Medical Association Journal in 2017 found that participants who consumed artificial sweeteners had higher rates of obesity, high blood pressure, metabolic syndrome, type 2 diabetes, and heart problems. Additionally, a 2016 study in the Journal of Hypertension found that fifth graders who drank diet soda had higher blood pressure levels than those who drank regular soft drinks or no soft drinks. However, it is important to note that these children may have had pre-existing medical conditions that predisposed them to high blood pressure, which may have influenced their beverage choice.
The potential link between artificial sweeteners and health issues is gaining attention, but the exact role played by diet drinks is unclear. While diet drinks are low in calories and sugar, they lack nutrients and contain artificial sweeteners that have been associated with negative health effects. For example, aspartame, a common nonnutritive sweetener, has been found to decrease the production of short-chain fatty acids, which play a role in preventing inflammatory diseases and regulating body weight. However, more studies are needed to confirm these findings and fully understand the impact of artificial sweeteners on gut health and overall wellness.
Maintaining a balanced diet and a healthy lifestyle are crucial for managing and preventing high blood pressure and other related health issues. While diet drinks may not be as harmless as previously thought, it is important to note that they are just one component of overall dietary and lifestyle patterns that influence health outcomes.

Caffeine and blood pressure
Caffeine is often blamed for raising blood pressure, and it is standard advice for people to avoid caffeine before having their blood pressure checked. However, the relationship between caffeine and blood pressure is complex and not yet fully understood. While some studies have found a link between caffeine consumption and increased blood pressure, others have not. For example, a 1987 Italian study suggested that coffee may even help to reduce blood pressure.
A study published in the Journal of Hypertension in February 2016 found that fifth graders who drank diet soda had higher blood pressure levels than those who drank regular soft drinks or no soft drinks. However, this may have been due to other medical conditions that predisposed them to high blood pressure, such as obesity. The Mayo Clinic also suggests that it is not the artificial sweeteners in diet soda that affect blood pressure but rather other ingredients.
A study by Harvard Health found that while a triple espresso did lead to increased blood caffeine levels in all subjects, not all experienced a rise in blood pressure. Interestingly, the espresso raised the systolic pressure of non-coffee drinkers by 13 mm Hg on average, but had no effect on habitual coffee drinkers. This suggests that habitual coffee drinkers may become acclimated to the ingredients in coffee, and their blood pressure does not rise as a result.
Another study published in the Journal of the American Heart Association found that participants with severe hypertension who drank two or more cups of coffee per day doubled their risk of dying from cardiovascular disease compared to non-coffee drinkers. However, drinking just one cup of coffee or any amount of green tea did not raise this risk. The study also suggested that polyphenols, micronutrients found in green tea with antioxidant and anti-inflammatory properties, may have offered some protection.
Overall, while caffeine may cause a temporary rise in blood pressure, particularly in those who are not habitual coffee drinkers, the relationship between caffeine and blood pressure is complex and not yet fully understood. Other ingredients in coffee may also play a role, and more research is needed to determine the exact nature of the relationship. In addition, lifestyle factors such as weight and exercise levels can also impact blood pressure, and it is important to consider these factors in conjunction with caffeine intake.

Salt and blood pressure
While there is no clear link between diet drinks and blood pressure, studies have found that long-term consumption of diet soda is associated with higher rates of obesity, high blood pressure, metabolic syndrome, type 2 diabetes, and heart problems.
Excess salt consumption is linked to high blood pressure. Salt contains sodium, which is closely linked to high blood pressure. While the recommended amount of salt intake is unknown, it is estimated that the average American consumes about 50% more than advised.
About a third of healthy people and 60% of people with high blood pressure are salt-sensitive, meaning their blood pressure rises by 5 points or more when they switch from a low-salt to a high-salt diet. However, it is important to note that an estimated one in 10 people have inverse salt sensitivity, where their blood pressure increases when they consume less salt.
Genetics plays a role in salt sensitivity, with 18 known genetic variants associated with salt sensitivity and blood pressure. For example, the striatin variant affects blood flow through the kidneys in men, while in women, it influences aldosterone, a hormone that regulates salt and water balance.
To reduce sodium intake, it is recommended to limit the consumption of processed foods, read labels, and opt for low-sodium or no-salt-added alternatives. Additionally, using salt substitutes, spices, and herbs can enhance food flavor without the negative health effects of salt.

Exercise and blood pressure
While there is some research to suggest that diet drinks may be linked to higher rates of high blood pressure, the evidence is not entirely clear. However, focusing on exercise, we can be more certain.
Exercise and physical activity are great ways to lower blood pressure and improve heart health. During exercise, blood pressure increases to supply additional blood flow to the muscles, but regular exercise has the overall effect of lowering resting blood pressure. This is because exercise keeps your heart and blood vessels in good condition. It also helps with weight loss, which can reduce blood pressure, as a healthy weight means the heart does not have to work as hard to pump blood around the body.
According to the NHS, adults should aim for at least 150 minutes (2 hours and 30 minutes) of moderate-intensity aerobic activity every week. This can include activities such as cycling or fast walking. There are also specific types of exercise that can help lower blood pressure, such as isometric exercises, which involve tightening specific muscle groups without moving the joints. Examples of isometric exercises include wall sits or extended planks.
High-intensity interval training is another form of exercise that has gained popularity due to its efficiency and potential for comparable benefits to more vigorous aerobic exercise. It is important to note that some types of exercise may not be suitable for everyone, especially those over 50 who have not exercised regularly. Consulting a doctor before beginning a new exercise regimen is always a good idea.
In addition to exercise, other lifestyle changes can also help lower blood pressure. These include losing weight if needed, eating a healthier diet, and reducing caffeine and alcohol intake, as excessive consumption of these beverages can contribute to increased blood pressure.
