Diets For High Blood Pressure And Thyroid.

Before discussing diets for high blood pressure and thyroid, it is important to know how the thyroid and high blood pressure are associated with each other. 

According to a recent study, hypothyroidism is also linked to a considerable increase in blood pressure. 

This is why the blood pressure of people with symptoms of hypothyroidism should be monitored carefully.

International studies have shown that people with hypothyroidism have significantly higher mean 24-hour systolic blood pressure and greater variability in 24-hour systolic blood pressure than healthy volunteers.

The results of this clinical trial were published in the Journal of Hypertension.

The study included 100 people who had just been diagnosed with hypothyroidism.

The mean systolic blood pressure in the hypothyroid patients was 139.0 ± 9.7 mm Hg. In the group of subjects without hypothyroidism, the mean systolic blood pressure was 112.3±8.8 mm Hg.

The patients had not previously taken blood pressure-lowering drugs or been treated for hypothyroidism.

The authors concluded that hypothyroidism may be an important predictor of high 24-hour mean systolic blood pressure.

Previously, only hyperthyroidism was thought to be the primary cause of elevated systolic (“high”) blood pressure, while hypothyroidism was responsible for elevated diastolic (“low”) blood pressure.

To treat high blood pressure, the diet should be as varied as possible to provide the body with all the nutrients it needs: fiber, Omega-3, quality protein, etc.

Dietary measures will have to be combined with regular physical activity to strengthen their action.

(a) Fibers:

Fiber is preferred as part of the dash diet, it reduces cholesterol levels and has a protective action on the cardiovascular system. At each meal, care should be taken to bring one of the following sources of fiber:

  • Fruit
  • Vegetables
  • Whole grains
  • Legumes

(b) Omega-3:

Omega-3s have positive effects on cardiovascular health.

They make it possible to thin the blood and regulate blood pressure and also have a most interesting anti-inflammatory effect.

At least once a day, one of the following sources of Omega-3 should be incorporated:

Walnut oil
Linseed oil
Rapeseed oil
Flax and chia seeds

(c) Lean and vegetable proteins:

Some sources of animal protein are also sources of saturated fat. It will therefore be necessary to choose foods that combine a good content of protein and fatty acids of good quality.

As part of the dash diet, the following foods should be integrated as often as possible for an optimal intake of good proteins:

  • Legumes
  • Pisces
  • Seafood
  • Poultry without skin
  • Lean pieces of meat
  • Tofu
  • Vegetable milk and soy yogurt
  • Skimmed milk and dairy products
  • Oleaginous

(d) Physical activity:

Physical activity helps fight against overweight while promoting the good health of the cardiovascular system.

It would have very positive effects on the regulation of blood pressure. It is recommended to practice 30 minutes of physical activity per day and to promote cardio activities of good intensity.

Example of activity recommended in case of high blood pressure:

  • Brisk walking
  • Running
  • Nordic Walking
  • Ramble
  • Bicycle
  • Dance

Other recommended foods:

  • Antioxidants
  • Foods with low energy density
  • Good hydration
  • Homemade

(e) Diet not recommended for high blood pressure:

It is recommended to adopt a more or less strict salt-free diet in case of hypertension.

This diet tends to put the cardiovascular system to rest and avoid all foods that could harm it such as alcohol, saturated fats, etc.

In addition, it will be necessary to avoid risky behaviors: smoking, a sedentary lifestyle, or an anarchic diet.


The dash diet is a low-salt diet. It is important, as a first step, to stop adding salt to dishes or when cooking.
Here is a list of high-salt foods to avoid as part of the high blood pressure diet:• Spice blends

  • Cube broths
  • Spice blends
  • Mustard
  • Cheese (limited to 1 serving per day)
  • Classic bread
  • Cold cuts
  • Smoked foods
  • Canned vegetables and fish
  • Industrial sauces
  • Industrial salt biscuits (e.g. chips)


Alcohol has a detrimental effect on arterial walls. It weakens the walls and, combined with the rise in blood pressure, increases the risk of cardiovascular accidents.

It is therefore recommended, as part of the diet for high blood pressure, to limit the consumption of alcohol to one serving per day in both men and women.

Red wine seems to be the least harmful alcohol for the heart.
One serving of alcohol is equivalent to:

  • 250ml of beer
  • 12,5cl of wine
  • 2.5cl of strong alcohol

Saturated and trans fats

Trans and saturated fats can prevent the beneficial action of Omega-3s. They would also be involved in the process of formation of atherosclerotic plaques.

Combined with high blood pressure, they, therefore, promote the risk of cardiovascular accidents. As part of the dash diet, we tend to limit the following foods:

  • Palm oil
  • Hydrogenated margarines
  • Industrial products
  • Ready meals
  • Butter, whole cream
  • Cheese
  • Cold cuts
  • Fatty meats
  • Fried and breaded products
  • Industrial sauces: mayonnaise, béchamel, etc.
  • Sweet or savory pastries and biscuits
  • Fast food, pizza, etc.


Like alcohol, tobacco weakens the arterial walls. Quitting smoking should therefore be one of the first reflexes to have in case of high blood pressure.

Putting together a diet and nutrition plan for your thyroid…
Below I cover 7 broader tips for a thyroid diet, consisting of foods that can stimulate your (slightly sluggish) thyroid…

(a) Iodine is essential in a thyroid diet!

Iodine is an essential component of thyroid hormones and therefore crucial for thyroid function. Both iodine deficiency and excessive iodine intake can interfere with thyroid function.

Make sure you get 150-300 micrograms of iodine daily. Iodine is found in saltwater fish, shellfish, seaweed, bread, brown rice, yogurt, cashew nuts, and iodized salt (JOZO®).

Note: if you suffer from clinical thyroid disease, it may be true that you should be sparing with your diet/nutritional iodine.

This is even more true if you are taking thyroid medication (levothyroxine and/or liothyronine) or if you need to undergo radioactive iodine blockade.

Note: without iodine from food, your thyroid cannot function! Unless you systematically take thyroid medication…

(b) Food for the thyroid: minerals!

Minerals are essential if you want to put together the right kind of food for your thyroid. In addition to iodine, there are several other minerals and trace elements that are essential for your (slow) thyroid.

The most important of these are:

  • Selenium (fish, seafood & cereals)
  • Zinc (seeds, kernels & oatmeal)
  • Iron (meat, legumes & almonds)
  • Copper (avocado, mushrooms & plums)
  • Magnesium (cocoa, bananas & wholemeal bread)

Selenium and zinc deficiencies are particularly common in the Netherlands. These substances should be included in the thyroid diet, as they are directly or indirectly involved in thyroid hormones.

(c) The thyroid gland needs nutrition with vitamins!

Your thyroid gland depends on a number of vitamins. In any case, make sure that your thyroid diet contains enough of the following vitamins:

  • Vitamin E (sunflower oil, cereals, halvarine & peanut butter)
  • Vitamin A & vitamin B12 (liver, meat, fish & eggs)
  • Vitamin D (cheese, meat, fish, butter & mushrooms)

The above vitamins are essential in a diet that should stimulate and maintain the thyroid…

(d) Dietary fiber = Food for the thyroid gland.

Hypothyroidism causes slowed metabolism and digestion. Dietary fibers, on the other hand, promote good digestion.

If you have a slow thyroid gland, it is therefore particularly important to eat enough fiber.

Dietary fiber is mainly found in vegetables, fruits, and cereals, and a thyroid diet should therefore consist largely of plant-based foods.

(e) Thyroid diet or gluten intolerance?

Thyroid problems are increasingly associated with gluten intolerance or celiac disease. Gluten is mainly found in cereals such as wheat, barley, rye, oats, spelt, and kamut (bread, pasta, cereals, biscuits, etc.).

Only 10% of all people with celiac disease know that they are gluten intolerant.

So if you suffer from an overactive or sluggish thyroid gland, it is not unwise to test yourself for celiac disease. This home test or self-test is also known as a gluten test or celiac test.

Perhaps a gluten-free diet is much more effective in your case than a thyroid diet…

(f) Thyroid diets contain as little sugar as possible

Sugars, thyroid hormone (thyroxine), and pancreatic hormone (insulin) interact. High blood sugar levels cause high insulin levels. High insulin levels can interfere with thyroid function.

If you want to follow a good thyroid-friendly diet, you should eat as little fast/simple sugar as possible, i.e. no candy, cake, ice cream, soda, etc. 

(g) No mineral supplements in a thyroid diet!

Minerals are an essential part of the diet to support a slow thyroid. The function of minerals and trace elements depends on an extremely delicate balance.

However, mineral supplements (pills and tablets) contain huge amounts of synthetic minerals.

Supplements will therefore never provide the same compounds and balance as natural nutrients. In many cases, they even upset the mineral balance. Minerals

Bottom Line:

Hypothyroidism is a disease affecting 1-2% of the world’s population. It can lead to fatigue, weight gain, and cold sensitivity.

Fortunately, the right foods with respect to diets for high blood pressure and thyroid and medicines can relieve symptoms and boost thyroid function.
Iodine, selenium, and zinc are all thyroid-friendly minerals.

A thyroid-friendly diet can help reduce symptoms and maintain a healthy weight. To achieve this, it is crucial to eat whole, unadulterated meals, and lean proteins.
