Can We Consume Milk and Tomatoes? [Plus Ketchup & Canned]

Can We Consume Milk and Tomatoes

Some foods can cause an upset stomach if consumed together.

This is generally because it causes a chemical reaction inside your stomach as it’s being digested.

Milk and tomatoes are both commonly consumed, so here’s whether it’s a good idea to consume them together.

Milk and tomatoes can be consumed together.

But, the acid in the tomatoes can slightly curdle the milk if a small amount of milk is added to a large number of tomatoes.

This can cause discomfort, vomiting, or diarrhea. But, the acid in tomatoes is quite weak so it’s unlikely to happen.

It’s much more likely to happen if you mix a portion of food or drink with much stronger acid such as orange juice, or vinegar.

When mixed with milk you will be able to see the milk curdle and turn the milk thicker, and into small blobs.

Below, I will explain whether there are any benefits to consuming milk with tomatoes.

As well as, if it can be mixed with other tomato products such as tomato paste, tinned tomatoes, and ketchup.

Benefits of Tin Tomatoes and Milk

Benefits of Tin Tomatoes and Milk

Tinned tomatoes are a convenient way to eat tomatoes because they’re precooked, and last for a very long time, much longer than fresh tomatoes.

Most people find milk creamy, and delicious to drink on its own.

Here’s a summary of if there are any benefits to consuming tinned tomatoes and milk.

There are no known benefits of combining tinned tomatoes and milk.

The benefits that you get from tinned tomatoes and milk separately are the same benefits you’ll get from eating them together.

Tomatoes are high in vitamin C, and milk is high in calcium and potassium.

As you may know, each different type of food contains a different amount of beneficial vitamins and minerals.

To get a better idea of the benefits of consuming milk with tinned tomatoes I’ve compiled a table showing the nutrients in both, and then the totals based on the recommended daily intake of each.

Tomatoes have certain nutrients that milk doesn’t have, these are:

  • Iron – tomatoes have 7% RDI, milk has 0% RDI
  • Manganese – tomatoes have 3% RDI, milk has 0% RDI
  • Vitamin C – tomatoes have 13% RDI, milk has 0% RDI
  • Vitamin E – tomatoes have 4% RDI, milk has 0% RDI
  • Vitamin K – tomatoes have 3% RDI, milk has 0% RDI

Milk only has two nutrients that tinned tomatoes don’t have, these are:

  • Vitamin B-12 – milk has 7% RDI, tomatoes have 0% RDI
  • Fat – milk has 5% RDI, tomatoes have 0% RDI

If you total all the nutrients in tomatoes and compare it to all the nutrients in the milk they have around about the same, as a percentage of RDI.

So, when you combine them you get double the amount of nutrients.

Therefore, the main benefit of consuming milk and canned tomatoes is that you will get double the nutrients.

Certain nutrients that tomatoes don’t have, milk has.

But, overall they are both about as nutrient-dense as each other.

And neither is dramatically healthier than the other.

As you may know canned foods last a very long time, and you may be curious how long canned tomatoes last.

I explained the answer to this question in this article about

how long canned tomatoes last

To show what happens when you mix acidic liquid with milk, here’s a video of a scientist who adds lemon juice to milk:

As you can see the milk becomes globby, and begins turning into something that resembles yogurt, though not as thick.

Interestingly this is how many types of cheese are made such as cream cheese.

Milk is heated and then lemon juice, lime juice, or vinegar are added. When this happens the milk separates into two parts.

What is called curds and whey.

The curds are the thick chunks of the milk that separate out.

These are pressed together in cheesecloth so that they combine with each other to make one solid mass.

There are two main acids that are present in tomatoes. Just by taste, you can tell they aren’t as acidic as lemons or limes.

I looked into a scientific study that determined what acids are in tomatoes, and how much of them there are in this article about the acids in tomatoes.

Tomato Paste and Milk for Weight Gain

Tomato Paste and Milk for Weight Gain

If you’re trying to put on weight because you’re a bit skinny, or are bulking up as part of going to the gym, generally you need to consume a good amount of calories.

On the flip side, if you’re trying to consume fewer calories to lose weight you need to evaluate all of the different foods you want to eat regularly so you can see what the best options are.

So, here’s whether tomato paste and milk are good or bad for weight gain.

Tomato paste is not good for weight gain but milk is.

A large serving (half a cup) of tomato paste contains 82 calories.

But, a large serving of milk (2 cups) contains 484 calories.

Tomato paste is reasonably good for weight loss, but it tastes very bad on its own.

The average amount of calories a person should eat to stay in average shape is about 2000 to 2500.

This means a large serving of tomato paste only contains 4.1% of the recommended daily intake of calories.

A large serving of milk contains 24.2% of your recommended daily intake of calories.

Therefore, milk is good on its own for weight gain.

Ketchup and Milk

Ketchup and Milk

Ketchup and milk are an unlikely pairing.

Ketchup is typically used on pastries, burgers, and hot chips.

Whereas, milk is typically not used as a condiment with other foods.

So, do ketchup and milk go together, and can you add ketchup to a glass of milk?

Some people think it tastes disgusting whereas others find it tastes quite delicious.

It depends on your unique palette and how much ketchup you add to the milk.

The idea of it repulses many people and is not something they would try. 

Certain food combinations depend on how you think about it before eating it.

For example, in Malaysia, a very popular dessert is a combination of licorice and corn.

If you were to ask me if I would like to eat that I would say no.

But, interestingly it tastes quite good. Also some people like eating honey and onion, and lettuce.

Which I personally am not a big fan of
