High BP Alert: What Not to Eat

One out of every four Indian adults has high blood pressure, and what makes the matter worse is that most of them are unaware of it, the research indicates.

It is for this reason that high blood pressure is also called the 'silent killer'. There are no warning symptoms such as headache or any unusual condition at the beginning of the problem which indicates that blood pressure is increasing and causing stress to your blood vessels, heart, and kidneys. 

But the heartening fact is that what you eat significantly and demonstrably impacts your blood pressure. No guesswork involved here. While some food products cause an increase in blood pressure, others will ensure that your levels remain where they should be.

Once your doctor has confirmed your high blood pressure status, it's now time to examine your food storage area.

Sodium Tops the List

Of course, salt will immediately come to mind, however, there is much more to the story than what is generally believed. Everybody knows that sodium leads to high blood pressure but most of us do not know the amount of salt that is secretly present in our food.  

Someone who is found suffering from high blood pressure needs to have an intake of not more than 1,500 milligrams of salt per day.

But even then, a bowl full of instant noodles would amount to at least 800 milligrams of salt while the same amount of soup would give you 900 milligrams.

What is worth noticing is the fact that packaged items like biscuits, namkeens and snack mixes often contribute hundreds of milligrams of sodium, thus, table salt is often not the leading contributor.  

Sodium causes water retention in the body, which directly results in increased blood volume which increases the pressure against the artery walls.

This is a well-established fact that has been repeatedly proven in nutritional studies and controlling sodium is one of the easiest ways to effectively lower blood pressure.

 Ultra-Processed Foods

Salt is not the only element present in processed and packaged foods that affect blood pressure. They also contain an abundance of trans fat, refined sugars, artificial flavors, and preservatives, which cause blood vessels to become diseased independently of sodium intake.  

A paper published in August 2024 by Johns Hopkins Bloomberg School of Public Health in the Journal of the American Heart Association observed adults aged middle-age for several years in the US. ¹

Eating highly processed foods was directly linked to a high risk of developing hypertension with consumption of sugar-sweetened beverages, processed meats, and margarines contributing to a high number of incidences.

On the contrary, people who ate the least amount of processed food had significantly lower incidences of hypertension. The research indicates a rather simple explanation for this, the more that food is modified industrially, the more problematic it will be for maintaining your blood pressure levels.  

In the context of India, this problem pertains to items like chips, packaged chutneys, ready-to-eat curries and processed food items like bakery products, which have become very popular in Indian households due to ease and convenience.

Pickles, Papads and the Problem of Hidden Salt

Even items like pickles and papads, though part of a traditional Indian diet, are extremely dangerous for people who are suffering from or prone to developing high blood pressure.

These food items are packed with a large amount of salt. In addition, soya sauce and highly salted chutneys used with most Indian meals are just as detrimental to your blood pressure control as any processed product.

These food items are not banned from consumption, the catch is in limiting their usage to special occasions rather than making them a regular part of your meal routine.

One or two papads at one instance, not everyday, and your cumulative sodium levels remain under control throughout the day.

Alcohol and Caffeine

Alcohol has both immediate and long-term negative effects on blood pressure readings. Continuous consumption of alcohol even if it is in moderate quantities has a proven link with high blood pressure. In cases of individuals with high blood pressure, the positive effect of alcohol is outmatched by the inherent risk.  

Caffeine, though does raise blood pressure reading, it does so only for a brief period and only for people sensitive to its effect or with high blood pressure that has gone out of control.

Three or four cups of tea or coffee daily should be reviewed with your physician if you fall in either of these categories.

Red Meat and Processed Meat

Red meat especially cuts with high amounts of fat and processed meat items such as salami, hot dogs, and sausages should only be consumed occasionally, as they can eventually contribute to artery damage due to high saturated fat and contain large quantities of sodium, particularly when it comes to processed meats.

Both the types of meat are not restricted and can be consumed ,however, in moderate amounts on a regular basis.

Where Does All This Lead Us

The solution is not only medication for hypertension. Numerous studies have proved that modifications in lifestyles, especially dietary modifications, play an important role in managing high blood pressure levels.

These foods are no strangers to us, because they are the highly-processed products, rich in salt content, and containing lots of alcohol. Recognizing such foods is the easy part; the difficult thing is to avoid consuming them.
