Do Unrefrigerated Smoothies Lose Nutrients Overnight

Do Smoothies Lose Nutrients Overnight? Here is the Detailed Answer

I am a busy mom of three, and I make smoothies every day. However, this morning, while my 7-year old was eating breakfast before school, she asked me, “do smoothies lose nutrients overnight?” This may sound like a silly question, but it deserved to dig deeper to find out the truth.

This is a question that many people have asked, and it seems to be an age-old debate. Some say no, while others affirm yes. The primary reason why this has been debated so much could be because the complex answer can’t be summarized in just Yes or No.

It’s difficult to find any research on this topic outside of some US government agencies saying “yes/no,” so we will have to do some digging.

Smoothies are an easy and delicious way to get healthy food into your diet. They are a great way to create a healthy breakfast, snack, lunch, or dinner. Smoothies are typically made up of some fruit, vegetables, and other ingredients that provide an excellent balance.

So, Do you have to drink a smoothie right away?

The short answer is No; you don’t have to drink a smoothie right away. You can keep your smoothie unrefrigerated for a few hours, you can store it in the fridge for up to 48 hours and enjoy it cold, or you can also store it in the freezer for up to 3 months.

Do Smoothies Lose Nutrients Overnight?

Smoothies are an excellent method to get the minerals, vitamins, fiber, protein, and iron your body needs.

Once smoothies are exposed to oxygen, they begin the oxidation process. Oxidation is a rapid process that will lead to the breakdown of a significant amount of nutrients in the smoothie.

Unfortunately, Smoothies lose some of their nutrients overnight. This is because the healthy smoothies are made out of the freshest contents. The fact is fruits and vegetables start losing their nutrients and vitamins as soon as they are harvested. So, Whether you use nuts to give your smoothie a rich texture, green vegetables to make it much healthier, or frozen fruits to make lovely flavors, all these are generally recommended to eat immediately. So, smoothies will spoil if left unconsumed for a long time.

It is essential to understand why smoothies lose nutrients so you can follow the logic behind adequately storing. Fundamentally, when the nuts, fruits, vegetables, or other food substances you use in preparing your smoothies are exposed to air, the oxidization happens.

When blending fresh vegetables and fruits, their cells are cut open. Therefore they are exposed to air. Oxygen is the main cause of the oxidation process. Being exposed to oxygen causes the cells of fruit or vegetable to break down, which leads to loss of nutrients and in foods. Therefore the smoothies lose their nutritional value as well.

While oxygen does affect the smoothie and will lose plenty of its nutritional values if kept overnight, the positive thing here is that not all minerals, vitamins, and nutrients will be lost overnight.

So, according to the different ingredients utilized to produce a smoothie, the oxidization process will span over different periods. As a result, some may be faster than others.

Any food that includes citric acid will reduce the pH of the smoothie. This slows down the enzymes that cause spoiling. Pineapple and Citrus fruits are good examples of this.

Adding some lime juice, lemon juice (or other citrus fruit juice) will help extend the shelf life of your smoothie. But, it is necessary that acidic foods could be harsh when consumed on an empty stomach.

However, it is better to drink a green smoothie right after making it to avoid separation. You will see that the green smoothie quickly begins to lose its taste, even if stored properly. In addition, green smoothies with kale can begin to become very gelatinous and dense after an hour or two.

Tips for Maintaining the Smoothies Healthy & Fresh with Optimum Nutrients

Below are some tips to keep the smoothies fresh with maximum nutrients. All the following tips are helpful to decrease the loss of vitamins and nutrients. They help to maintain the smoothie healthily & fresh.

Container Is the Key

The primary essential tip to not lose nutrients of smoothies overnight is all about the container where you keep your smoothie. You need to ensure you fill the container to the brim with a smoothie so there is no air entry in the. By doing this, you will slow the oxidation process. Consequently, there are fewer possibilities of an oxidization in the container. Hence, A glass container is the most effective type of container that includes an airtight cover. Also, make sure that the container you are using for storing your smoothie comes with BPA-free plastic lids. So, choosing the proper container is important store smoothies and maintain its optimum nutritional values.

The containers with quality airtight are the most appropriate for saving your smoothies overnight. The smoothie will remain with maximum nutrition.

The oxidization process becomes slower by putting the smoothie container in the fridge. Therefore, it will keep nutritional values remain in the smoothie. Also, the process of spoilage decelerates.

Put More Vitamin C

The last significant tip is adding lemon or lime to your drink. Citrus is the most significant ingredient to keep the smoothies healthy & fresh with maximum nutrients. When you put more amount of vitamin C, which is anti-oxidative, preserving the nutrients fresh for a long time, and will protect against the process of oxidization.

Thicker smoothies are harder to freeze because they will not freeze as easily and will take longer to thaw again.

My Smoothie is Separated. Is It a Sign of Nutrient Loss?

Luckily, this separation is not an indication of nutrient loss or spoilage. All you have to do is stir or shake your smoothie to mix it up again.

Green smoothies do not need to be frozen, but if you are looking for a refreshing drink to share with friends, freezing them will make them last longer.
