## 6 Common Diet Mistakes That Are Raising Your Blood Pressure (and How to Fix Them)

High blood pressure, also known as hypertension, is a common yet dangerous condition that increases the risk of heart disease, stroke, and kidney damage. While medications can help manage blood pressure, dietary choices play a pivotal role too. Unfortunately, some common diet mistakes might be inadvertently pushing your blood pressure higher. Here, we look into six such mistakes and provide actionable ways to fix them.

Understanding Blood Pressure

Blood pressure measures the force exerted against the walls of your arteries as your heart pumps blood through your body. It is measured in millimeters of mercury (mmHg) and presented as two numbers: systolic (pressure during heartbeats) over diastolic (pressure when the heart rests between beats). Normal blood pressure is typically around 120/80 mmHg. Anything consistently above 130/80 mmHg is generally considered high.

Mistake 1: Consuming Too Much Salt

The Problem

One of the most well-established dietary factors that can raise blood pressure is a high intake of sodium. Sodium causes your body to retain water, which increases blood volume. This, in turn, puts extra pressure on your arteries.

Most sodium in our diet comes not from the salt shaker but from processed and restaurant foods. Common culprits include canned soups, pizzas, deli meats, and snack foods.

How to Fix It

The American Heart Association recommends no more than 2,300 milligrams (mg) of sodium per day, with an ideal limit of no more than 1,500 mg for most adults. Here’s how to cut down on sodium:

• Read food labels: Opt for "low-sodium" or "no-salt-added" versions of products.
• Cook fresh foods: Preparing meals from scratch gives you complete control over sodium content.
• Flavor with herbs and spices: Use herbs, spices, lemon juice, or citrus zest instead of salt for flavor.
• Gradually reduce salt usage: Your taste buds can adjust to less salty flavors over time.

Mistake 2: Not Eating Enough Potassium-Rich Foods

The Problem

Potassium helps balance the sodium levels in your cells. Without adequate potassium, sodium can build up in the blood, leading to higher blood pressure. The typical Western diet is rich in sodium and often low in potassium, which exacerbates this imbalance.

How to Fix It

To keep blood pressure in check, aim for a diet rich in potassium:

• Include fruits and vegetables: Bananas, oranges, cantaloupe, spinach, broccoli, and potatoes are excellent sources of potassium.
• Opt for legumes and dairy products: Beans, lentils, and yogurt also offer substantial amounts of potassium.
• The aim should be to get at least 3,500 to 4,700 mg of potassium per day through your diet.

Mistake 3: Overconsumption of Alcohol

The Problem

Regular heavy drinking can dramatically raise blood pressure. Alcohol can damage artery walls, making it harder for your blood vessels to expand and contract properly. Consuming more than moderate amounts of alcohol can directly raise blood pressure and also contribute to weight gain, which itself is a risk factor for hypertension.

How to Fix It

Moderation is key:

• Limit alcohol intake: For men, this means up to two drinks per day, while for women, it should be up to one drink per day (where one drink is defined as 5 ounces of wine, a 12-ounce beer, or 1.5 ounces of distilled spirits).
• Consider alcohol-free days: Designate several days per week where you completely refrain from drinking alcohol.
• Be aware of serving sizes: Many people underestimate how much they drink. Use a shot glass for spirits or a measuring cup for wine.

Mistake 4: Eating Too Much Processed and Packaged Foods

The Problem

Processed and packaged foods often contain high amounts of sodium, unhealthy fats, and added sugars which can contribute to high blood pressure. Some processed foods also contain trans fats which increase LDL cholesterol ("bad" cholesterol) and decrease HDL cholesterol ("good" cholesterol), contributing to arterial plaque buildup and hypertension.

How to Fix It

Shift toward a whole foods diet:

• Plan your meals: Base your diet around fruits, vegetables, whole grains, lean proteins, and healthy fats like avocado, nuts, and olive oil.
• Avoid foods labeled "partially hydrogenated oil": Even if it says "0 grams trans fat," such foods can still contain up to 0.5 grams of trans fat per serving.
• Cook more often: Homemade meals using fresh ingredients are typically lower in sodium and lacking unhealthy additives.

Mistake 5: Skipping Out on Foods Rich in Magnesium

The Problem

Magnesium is another mineral that supports healthy blood pressure by helping blood vessels relax. A deficiency in magnesium might make it tougher for your blood vessels to relax, thus increasing resistance and raising blood pressure.

How to Fix It

To make sure you’re getting enough magnesium:

• Eat magnesium-rich foods: Green leafy vegetables (like spinach and kale), nuts (such as almonds and peanuts), seeds (flax, pumpkin, chia), whole grains, and soy products are great sources.
• Check your magnesium intake: Women should aim for about 310-320 mg per day, while men need around 400-420 mg per day.
• Consider a supplement: If you find it challenging to consume enough magnesium through food alone, talk to a healthcare provider about taking a supplement.

Mistake 6: Consuming Foods High in Added Sugars

The Problem

Diets high in added sugars can contribute indirectly to high blood pressure by causing weight gain and increased insulin levels, which make you retain sodium and water, consequently raising blood pressure.

How to Fix It

Focus on reducing added sugars in your diet:

• Read ingredient labels: Watch out for sugar disguised as sucrose, high fructose corn syrup, maltose, dextrose, and others.
• Limit sugary beverages: Sodas, juices, and flavored coffee drinks can be high in added sugars. Opt for water, herbal teas, or black coffee instead.
• Choose natural sweeteners: If you need a sweet fix, use fruits such as berries or a small amount of honey or maple syrup.

The Bottom Line

Managing your blood pressure through diet is a powerful way to protect your cardiovascular health. By addressing these six common dietary mistakes—excessive salt intake, insufficient potassium, alcohol overconsumption, reliance on processed foods, magnesium deficiency, and high added sugar consumption—you can make meaningful changes that benefit your blood pressure and overall health.

Making gradual changes can lead to long-term healthy habits. Always remember to consult with a healthcare provider or a registered dietitian for personalized dietary advice tailored to your needs.

FAQs

Q: How much salt should I aim to consume daily if I have high blood pressure?

A: Ideally, individuals with high blood pressure should aim for no more than 1,500 mg of sodium per day.

Q: Are there any specific diets that help manage blood pressure?

A: The DASH (Dietary Approaches to Stop Hypertension) diet is specifically designed to help lower blood pressure. It emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy while minimizing salt, red meat, and added sugars.

Q: Can drinking tea help lower blood pressure?

A: Yes, some studies suggest that drinking green tea regularly might modestly lower blood pressure due to its polyphenol content. However, it should be part of a balanced diet and lifestyle.

Q: How quickly can dietary changes affect my blood pressure?

A: Some dietary changes, like reducing sodium intake, can yield results in a matter of weeks. Consistent healthy eating habits over a longer period can lead to sustained blood pressure improvements.

Q: Is it okay to use salt substitutes?

A: Salt substitutes, which often contain potassium chloride instead of sodium chloride, can be beneficial for some people. However, they may not be safe for those with kidney issues or who are on certain medications. Always check with a healthcare provider first.
