The alkaline diet has been around for years. Like many popular nutrition trends, it has attracted plenty of attention, enthusiastic supporters and some fairly ambitious health claims.
You may have heard that eating alkaline foods can change your body’s pH, reduce acidity or even protect you from certain diseases. Some of those claims are much stronger than the evidence supports.
That does not mean there is nothing useful about the alkaline diet.
In fact, when you look beyond the pH claims, much of the advice is surprisingly sensible. Eating more vegetables and fruit, choosing whole grains, cutting back on heavily processed foods, drinking enough water and reducing excessive sugar are all habits that can contribute to a healthier diet.
So what is the alkaline diet really about, and is there anything worth taking from it?
Let’s look at the idea without the hype.
What is the alkaline diet?
The basic idea behind an alkaline diet is that different foods produce different effects after they are digested and metabolised.
Foods commonly described as alkaline forming include most vegetables, fruit and legumes. Foods often described as acid forming include meat, dairy products, eggs and many highly processed foods.
The important point, however, is that eating an alkaline food does not simply make your blood alkaline.
Your blood is maintained within a very narrow pH range, and your lungs and kidneys work continuously to keep it there. Food does not meaningfully change your blood pH under normal circumstances.
That is why claims that an alkaline diet can dramatically alter your body’s overall pH should be treated with caution.
Where the diet becomes more interesting is in the type of foods it encourages.
A plate filled with vegetables, beans, whole grains and other minimally processed foods is generally going to provide more fibre, vitamins, minerals and plant compounds than a diet dominated by sugary snacks, processed meat, refined carbohydrates and convenience food.
That distinction is much more useful than worrying about whether an individual food is technically acidic or alkaline.
Does an alkaline diet actually improve your health?
There is no need to accept every claim made about alkaline diets to recognise that diet quality matters.
A diet based heavily on ultra processed foods, added sugar and refined carbohydrates is unlikely to provide the same nutritional value as one containing plenty of vegetables, fruit, whole grains, pulses, nuts and seeds.
The same applies to weight management. A meal based around vegetables, lean protein and whole grains is generally more filling and nutrient dense than a meal dominated by refined carbohydrates and highly processed ingredients.
This is where the alkaline approach can be useful as a simple framework.
Think less about changing your body’s pH and more about improving what goes on your plate.
1. Eat more vegetables and fruit
If there is one part of the alkaline diet worth taking seriously, it is the emphasis on plant foods.
Vegetables and fruit provide fibre, vitamins, minerals and a wide range of naturally occurring plant compounds. They also add colour, variety and volume to meals without relying heavily on processed ingredients.
Try making vegetables part of the main structure of your meal rather than something added at the end.
For example, instead of thinking of meat or pasta as the entire meal, build the plate around vegetables and then add your protein and carbohydrate sources around them.
Fresh fruit can also be an easy alternative to biscuits, sweets or other highly processed snacks.
You do not have to make dramatic changes overnight. Adding an extra portion of vegetables to lunch and replacing one processed snack with fruit is already a useful start.
2. Reduce added sugar
You do not have to eliminate sugar completely to eat well.
The problem is that added sugar can appear in far more foods than people realise. Sweets, cakes, biscuits and fizzy drinks are obvious examples, but sugar can also turn up in breakfast cereals, flavoured yoghurts, sauces, desserts and sweetened drinks.
Reading food labels is one of the easiest ways to become more aware of how much sugar you are actually consuming.
You may also find that your taste changes gradually. Once you get used to less sweetness, some products that previously tasted normal can suddenly seem excessively sweet.
Rather than trying to follow a completely sugar free diet, focus on reducing the foods that contribute the most added sugar to your everyday diet.
3. Cut back on heavily processed foods
Convenience foods are not automatically unhealthy, and there is no realistic need to prepare every meal completely from scratch.
The problem comes when highly processed foods make up most of your diet.
Ready meals, processed meats, packaged snacks, sugary drinks and commercial baked goods can be convenient, but many are also relatively high in salt, saturated fat, sugar or calories while providing less fibre and micronutrient variety than whole foods.
The solution is not perfection.
It is having better options available when you are busy.
A few simple meals that can be prepared quickly can make it much easier to avoid relying on takeaway food or snacks when you have had a long day.
For people looking for convenient nutrition options, the Herbalife Formula 1 shakes available from MakeMeHealthier are one option to consider. They provide a convenient meal replacement format with protein, fibre, vitamins and minerals and can be prepared quickly when a normal meal is difficult to manage.
They should be viewed as a convenient part of an overall eating plan, rather than as a replacement for a varied diet.
4. Be sensible about red meat
An alkaline diet does not require you to believe that red meat is inherently bad.
Red meat can provide useful nutrients, including protein, iron, zinc and vitamin B12. The issue is more about quantity and the type of meat you regularly eat.
Processed meats such as sausages, bacon and some deli meats are generally foods worth limiting. You can also improve variety by replacing some meat based meals with fish, eggs, beans, lentils, poultry or other protein sources.
For example, you might have a lentil based meal one day, oily fish another day and a chicken or lean meat meal later in the week.
A varied diet is usually easier to maintain than a list of foods you are told you must never eat.
5. Choose whole grains more often
White bread, white rice and regular pasta are not foods you need to fear.
However, wholegrain alternatives can provide more fibre and nutrients and may help you feel fuller.
Oats, wholemeal bread, brown rice, wholegrain pasta, barley and other whole grains can all fit into a balanced diet.
If you currently eat refined grains most of the time, start with simple swaps rather than changing everything at once.
Try porridge instead of a sugary breakfast cereal. Choose wholemeal bread for sandwiches. Use brown rice with one of your regular meals.
Small changes tend to be easier to maintain than a complete dietary overhaul.
6. Include healthy sources of fat
The word “fat” still makes some people nervous, particularly if they are trying to lose weight.
But dietary fat is not something that needs to be removed completely.
Foods such as nuts, seeds, avocado, olive oil and oily fish provide useful unsaturated fats and can form part of a balanced diet.
The important thing is portion size because fats are energy dense.
A handful of nuts can be a nutritious snack, but eating several handfuls without noticing can add considerably more calories than intended.
As with most foods, context and quantity matter.
7. Drink enough water
Hydration is another area where the alkaline diet can encourage a useful habit.
Water is the obvious choice, but tea and other suitable drinks can also contribute to your daily fluid intake.
Rather than waiting until you are extremely thirsty, keep water available throughout the day.
If you regularly mistake thirst for hunger, staying hydrated may also help you become more aware of whether you genuinely need food or simply need something to drink.
There is no need to spend money on expensive “alkaline water” simply because it is marketed as being healthier. Your body already has highly effective systems for regulating its internal pH.
8. Do not try to change everything at once
This is probably the most practical piece of advice for anyone considering an alkaline style of diet.
Changing everything overnight rarely works.
You might decide to remove sugar, stop eating meat, eliminate bread, switch to organic food, start juicing and completely change your breakfast all in the same week.
It sounds impressive.
It is also difficult to maintain.
A better approach is to make one or two changes at a time.
Start with breakfast. Then improve your lunch. Add more vegetables to dinner. Replace a few processed snacks. Drink more water.
Once those habits feel normal, move on to the next change.
That is how a temporary diet can gradually become a sustainable way of eating.
What about a convenient breakfast?
Breakfast is often where healthy intentions fall apart.
You may know that you should eat something nutritious, but mornings can be rushed. Work, school, commuting and family responsibilities can leave very little time for preparing food.
That is one reason meal replacement products can be useful for some people.
MakeMeHealthier’s Herbalife Formula 1 range is designed as a convenient meal replacement option and comes in a range of flavours. The product information states that Formula 1 provides protein, fibre, vitamins and minerals and can be prepared quickly.
If you are considering different Herbalife products rather than just Formula 1, the Herbalife UK product guide brings together the main product categories available through MakeMeHealthier, including nutritional shakes, protein products and wellness options.
The key is to use convenience intelligently. A shake can be useful on a rushed morning, but it should not become an excuse to avoid eating a varied diet altogether.
What can you realistically expect from an alkaline diet?
This is where it is important to separate the useful parts of the diet from the more dramatic claims.
There is not good evidence that eating alkaline foods will dramatically change your blood pH or cure diseases.
Your body regulates blood pH very tightly through the lungs and kidneys.
What can change is the quality of your diet.
If following an alkaline diet encourages you to eat more vegetables and fruit, consume more fibre, drink more water and reduce your intake of highly processed foods and excessive sugar, those are worthwhile changes.
You may also find that meals based around whole foods are more filling and easier to manage when you are trying to maintain a healthy weight.
In other words, you do not necessarily need to believe the pH theory to benefit from many of the eating habits associated with an alkaline diet.
The bottom line
The alkaline diet is often presented as though it holds the secret to changing the chemistry of your body.
It does not.
Your body already has sophisticated systems for keeping its internal environment within a very narrow range.
But that does not make the entire concept useless.
Strip away the exaggerated claims and you are left with some straightforward nutritional advice: eat more plants, choose whole foods more often, reduce excessive sugar and highly processed food, drink enough water and make your meals varied.
Those are habits worth building regardless of whether you call your diet alkaline, healthy, balanced or simply sensible.
