High blood pressure, or hypertension, is a common condition that increases the risk of heart disease and stroke. Diet plays a crucial role in managing blood pressure, and certain types of dietary fats can make hypertension worse.
Let’s explore which fats to avoid if you have high blood pressure, supported by research and explained in simple terms.
First, let’s talk about trans fats. Trans fats are artificially created fats found in many processed foods, such as baked goods, snacks, and margarine. They are used to extend shelf life and improve texture, but they are harmful to health.
Research has shown that trans fats increase levels of bad cholesterol (LDL) and decrease levels of good cholesterol (HDL). This combination can lead to clogged arteries and higher blood pressure.
A study published in the New England Journal of Medicine found that eliminating trans fats from the diet could significantly reduce the risk of heart disease and lower blood pressure. To avoid trans fats, read food labels and look for “partially hydrogenated oils” – these are trans fats in disguise.
Saturated fats are another type of fat to be cautious about. These fats are found in animal products like fatty cuts of meat, butter, cheese, and full-fat dairy, as well as some plant oils like coconut oil and palm oil.
High intake of saturated fats can raise LDL cholesterol levels, contributing to higher blood pressure and heart disease. The American Heart Association recommends that people with high blood pressure limit saturated fat intake to less than 6% of their total daily calories.
For someone eating 2,000 calories a day, this means no more than 13 grams of saturated fat. Research published in the Journal of the American College of Cardiology supports this guideline, showing that reducing saturated fat intake can help lower blood pressure.
Instead of saturated and trans fats, it’s beneficial to focus on healthier fats. Unsaturated fats, found in foods like olive oil, avocados, nuts, and fatty fish, can help lower bad cholesterol levels and improve heart health.
These fats are known to have a positive effect on blood pressure. A study in the American Journal of Clinical Nutrition found that replacing saturated fats with unsaturated fats in the diet led to significant reductions in blood pressure.
Another type of fat to be mindful of is omega-6 fatty acids. While these fats are essential for health, they can be problematic when consumed in excess, particularly when the balance between omega-6 and omega-3 fatty acids is off.
Omega-6 fats are found in many vegetable oils, such as corn, soybean, and sunflower oils, which are commonly used in processed and fried foods.
A high intake of omega-6 fats, without enough omega-3s (found in fish, flaxseeds, and walnuts), can promote inflammation and potentially raise blood pressure.
Research in the Journal of Hypertension suggests that maintaining a healthy balance between omega-6 and omega-3 fats can help manage blood pressure.
To improve heart health and manage high blood pressure, it’s also important to consider overall dietary patterns. The DASH (Dietary Approaches to Stop Hypertension) diet is specifically designed to help lower blood pressure.
This diet emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy while reducing intake of saturated fats, trans fats, and sodium. Studies have shown that the DASH diet can significantly lower blood pressure and improve heart health.
For example, a study in the New England Journal of Medicine found that people following the DASH diet experienced significant reductions in both systolic and diastolic blood pressure.
In summary, to manage high blood pressure, it’s important to avoid trans fats and limit saturated fats. Focus instead on consuming healthy unsaturated fats, such as those found in olive oil, avocados, nuts, and fatty fish.
Be mindful of your intake of omega-6 fatty acids and strive for a balance with omega-3s. Following a heart-healthy diet like the DASH diet can further help manage blood pressure and improve overall heart health.
By making these dietary changes, individuals with high blood pressure can take significant steps towards better health and a lower risk of heart disease.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more information about blood pressure, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
