Intermittent Fasting – The advantages, disadvantages and explanations – Sapje

What is intermittent fasting?

Intermittent fasting, you hear everyone talking about it these days. But why should you do it? What are the possible effects? And what should you pay attention to? In other words, what are the advantages and what are the disadvantages of intermittent fasting? In this article we take a closer look at intermittent fasting, perhaps the most popular form of fasting right now.

Intermittent fasting meaning

Intermittent fasting is also known as periodic fasting. This is because this form of fasting refers to the times when you eat. And especially how long the periods are when you don’t eat. The best known variant of intermittent fasting is the 16-8 schedule. This involves fasting for 16 consecutive hours and then returning to a normal eating pattern for 8 hours. If you stop eating at 8 p.m. in the evening, you may start again at noon the next afternoon.

Benefits of intermittent fasting

Some of the benefits of intermittent fasting at a glance:

  • You are more conscious about food. During intermittent fasting, you are conscious about when you eat, which can also cause you to pay more attention to what you eat.
  • Because you have less time to eat, you also have fewer moments in a day to choose unhealthy snacks.
  • It saves you time because you eat at fewer times and thus have more room for other things.

Disadvantages of intermittent fasting

Every advantage has its disadvantage, a certain Johan Cruijff once said. The same goes for intermittent fasting. A few intermittent fasting disadvantages in a row.

  • You may feel sluggish at times during intermittent fasting. This is because your body is not used to this eating pattern. Often this is temporary and you will regain more energy after a while.
  • It takes time in preparation. You have to order your cleanse and schedule it well in jed jerk schedule.

Intermittent fasting drinking

It is not that you cannot drink during intermittent fasting periods. However, it is good to pay attention to exactly what you drink. Preferably drink low-calorie drinks. Like water, coffee and tea. And all without sugar. Especially water and white, green or herbal tea are responsible choices.

Intermittent fasting and nutrition

It is important to keep eating healthy and varied foods during the periods when you are allowed to eat. Our vegetable juices can help you do just that. If you want to be completely unburdened and receive the cleanse ready-made at home, you can also order it from us.

We focus on several categories, from fruits and vegetables to breads and beverages, all in line with the Five-Style.

Disc of five

Why Healthy Snacks Are Important

Healthy snacks not only help satisfy hunger between meals, but they also provide important nutrients that contribute to a balanced diet. They can prevent you from reaching for unhealthy snacks, which are often high in sugar, salt and saturated fat.

Vegetables and Legumes as Snacks

Nutritious Vegetable Snacks

Vegetables are an excellent choice for snacks because of their low calorie content and high nutritional value. Here are some suggestions:

  • Sweet bell pepper strips: Colorful and rich in vitamin C.

Fruits and Nuts: The Sweet and Crunchy Options

Fresh Fruit: The Natural Sweetness

Fruit is an excellent source of vitamins, minerals and fiber. Some healthy choices include:

  • Apples and Bananas: Easy to carry and rich in nutrients.
  • Berries: Blueberries, raspberries and strawberries are low in calories and high in antioxidants.

Nuts: Nutritious and Filling

Nuts are rich in healthy fats, protein and fiber. For example, try:

  • Unsalted Almonds: A handful is enough to keep your energy levels up.
  • Walnuts: Good for the brain due to their high content of omega-3 fatty acids.

Bread and Wraps: Filling and Varied Snacks

Healthy Bread Options

Bread can also be a healthy snack if properly chosen and prepared. Consider:

  • Whole Wheat Bread with Avocado: Rich in fiber and healthy fats.
  • Rye Bread with Hummus: A high-fiber alternative with a creamy topping.

Wraps: Versatile and Delicious

Wraps can be filled in a variety of ways. Some ideas include:

  • Whole Wheat Wrap with Chicken and Vegetables: Rich in protein and vitamins.
  • Wrap with Hummus and Vegetables: A vegetarian option full of flavor.

Healthy Drinks: Hydrating Without Sugars

Water: The Best Choice

Water remains the best beverage for hydration. Add a slice of lemon or mint for extra flavor.

Tea and Coffee

  • Tea: Herbal teas such as chamomile or green tea offer flavor without calories.
  • Black Coffee: Without sugar and milk a low-calorie pick-me-up.

Vegetable juices

Normally, we often choose the delicious fruit juices in the store. However, these contain a lot of natural sugars, which is best avoided. Therefore, it is better to choose vegetable juices, preferably those made with a slow juicer. This is because slow juicers retain more nutrients and enzymes because they press the vegetables at a low speed, which makes for a healthier and more nutritious juice.

Nightshade, what is it?

Potato, tomato and eggplant, what do they have in common? At first glance, not that much. Yet they are all part of the nightshade family. In this blog, we will discuss which vegetables are nightshades, why they belong to this family and what they are good for.

Background

The nightshade family (Solanaceae) is a family of more than 2,300 different plant species, most members of the family are shrubby plants. A smaller part of the family is herbs or small trees.

Name

The name “nightshade” seems to be possibly derived from the word “damage,” which has its origin in the word “shade.” The family gets its name from one plant, the black nightshade. It is conceivable that the first part of the name refers to the dark color of the berries, reminiscent of the darkness of the night.

Most well-known members of the nightshade family

Potato

Probably potato is the most important and well-known member of the nightshade family. Potato is a plant that grows tubers underground, which are edible, and it grows a small deciduous plant above ground. The potato stores a store of energy in its tubers in the form of starch. It is generally not recommended to eat potato raw because of the harmful substance solanine, which is broken down when you cook it.

Eaten in Holland for centuries, the boiled tuber was brought over from America in the 16th century. At the time of the industrial revolution, a large part of the average worker’s diet consisted of potatoes because they are cheap and nutritious. The potato contains fiber and many koohlydrates, but at the same time very little sugar. The potato contains almost no fats, and is rich in vitamins C, B6 and potassium, among others.

Remarkably, sweet potato is not a relative of the “regular” potato, the sweet potato belongs to the wine family (Convolvulaceae). Sweet potato contains inulin, unlike regular potato which contains starch. Inulin is more suitable for patients with diabetes because it digests more slowly than starch. Also try sweet potato soup.

Tomato

Tomato is also a well-known member. Tomato plants grow as a kind of bush above the ground, from which tomatoes grow like berries. It is impossible to imagine Italian cuisine without the tomato, yet this plant is not native to Europe either. This plant has its roots in South America, where it was grown particularly in the areas around the Andes Mountains.

Among other things, the tomato is known for the presence of the compound: lycopene, which is the natural dye to which the tomato owes its red color. This antioxidant has received much attention in science over the years, there is convincing evidence that it would support in the prevention of chronic diseases[1]. Read more about the benefits of tomatoes in the benefits of tomato soup.

Tobacco

Even tobacco is part of the nightshade family. The tobacco plant, native to the Americas, is a crop that has been grown and used for centuries by Native American peoples for ritual and medicinal purposes. The main ingredient in cigarettes and cigars is controversial due to the harmful effect on the body that smoking tobacco has. Tobacco leaves are used for this purpose because of the presence of nicotine, an addictive and stimulant substance, which is linked to several health problems, including cancer and heart disease.

Other members

Other well-known (edible) members of the family are:

  • Eggplant
  • Bell pepper
  • Cayenne pepper
  • Goji berries

Features

Now that you know some prominent members of the family, you have a certain picture, but how can you identify the next member of the family? There are a number of characteristics by which you can identify a member of the nightshade family. First of all the fruit type, in the nightshade family they are often berries, in the case of tomato very large berries, but also in the case of the potato plant you can see above the ground some kind of berries.

In addition, nightshade can be identified by its flower. Very often nightshade flowers have five petals that are all about the same, looking a bit like a star. The flowers can be white, yellow, purple or blue.

The image below shows both the berries and the typical flower shape of a nightshade.

Example of a typical nightshade

Phytoftora

Every potato farmer’s nightmare. Phytophthora is a plant disease best known for infecting potatoes; it is also called the “potato disease. Literally translated from Greek, phytophthora means “the plant destroyer. Phytophthora is a genus of fungal öomycetes, symptoms include leaf discoloration, wilting, root rot and eventually a dead plant. Bad news, then. Nightshade-like plants are known to be susceptible to phytophthora.

What is nightshade good for?

First of all, let’s mention that not all vegetables and plants belonging to this family are necessarily good. In fact, many of them are even harmful. All the vegetables that you can safely eat, either raw or after cooking, have their own health benefits. Vitamins and minerals you can find in some members are vitamin C, B6, potassium and so on. All of these vegetables (and spices) can contribute to a healthy diet in which you vary enough and get to your daily serving of fruits and vegetables each day.

What does nightshade do to your body?
Nightshade plants contain a substance called solanine (and related alkaloids), which can be mildly toxic in large quantities. In normal amounts, they are both safe and nutritious for most people. But in people with sensitive digestion or autoimmune disorders, they can sometimes trigger inflammatory reactions, joint pain or intestinal discomfort. This varies greatly from person to person.
What is covered by nightshade?
Nightshade is a plant family that includes several well-known vegetables. The best known edible nightshades are:

– Tomatoes
– Potatoes
– Peppers
– Chilies
– Eggplants

These vegetables contain natural substances that can cause symptoms in some people, especially if they are sensitive to them.
Which plants fall under nightshade?
In addition to the edible varieties, the nightshade family also includes non-edible or poisonous plants, such as:

– Bittersweet
– Thorn apple
– Black nightshade
– Tobacco
– Wolfberry (belladonna)

These species contain much higher concentrations of alkaloids and are not suitable for consumption.

Prolonged stress can be detrimental to both your physical and mental health. Develop healthy ways to manage stress, such as meditation, yoga or relaxation techniques. Finding an outlet for stress contributes to a more balanced and healthy life.

The impact of healthy eating on your body

That healthy eating is important is, of course, something you have long known. Yet for many people this is still very difficult. But what are the benefits of eating healthy? And what is the impact of healthy eating on your body? You will be surprised how many ways food can contribute to your health. In this blog we will tell you more about the positive effects of healthy food and how you can notice that you are eating healthy.

More energy

By eating healthy, you can support your energy levels. When you eat or drink something, your body goes to work to get usable energy from it. To feel energetic, not only do you need to get enough energy, but the quality of your food is also important. This is because you also need vitamins and minerals to release the energy from your food. These include the B vitamins and the minerals iron, calcium, copper and magnesium. These nutrients all contribute to the release of energy from your food.

For example, iron plays a role in the activity of certain enzymes involved in your energy metabolism (1). You can find a lot of iron in meat, fish, beans, nuts, spinach, turnip greens and kale. B vitamins are found in many different foods, such as (whole grain) cereals, meat, fish, dairy, vegetables and fruits (2).

By eating healthy, especially unprocessed and varied foods, you ensure that you get enough of all the important vitamins and minerals. In this way, you can support your energy levels.

Healthy skin

You probably don’t give it much thought, but your skin is a complex organ with many different functions. It acts as a barrier against outside influences, helps regulate your body temperature, functions as a shock absorber and so on (3). It is also important to eat well to keep your skin healthy. For example, vitamin C is important for the formation of collagen. This is a structural protein that helps strengthen the skin from the inside out. Vitamin C is especially abundant in fruits and vegetables, such as red peppers, red beets, Brussels sprouts red cabbage, broccoli, mango and lemon.

Other vitamins and minerals that help keep your skin healthy are vitamin A, vitamin B2, vitamin B3, copper, iodine and zinc.

Supporting your immune system

A good immune system helps protect your body from outside invaders. Healthy eating can also lend a hand here. There are an awful lot of vitamins and minerals that play a role in the functioning of your immune system. Vitamin C, zinc and vitamin D are perhaps the best known. But vitamin A, B6, B12, folate and the minerals iron, copper and selenium also have a positive influence on the functioning of your immune system.

Feel good

If you eat healthy, you will also find that you are more comfortable in your own skin. There are several reasons for this, including all the points we mentioned above. But healthy eating can even have a direct positive effect on how you feel. Here again, vitamins and minerals play a role. Biotin, folate, magnesium and vitamins B1, B3, B5, B6, B12 and vitamin C are all good for your mood, concentration and memory. Folate also contributes to your resistance to stress. To get all these nutrients, it is of course important to eat a healthy and varied diet. For example, folate is found in spinach, romaine lettuce and oranges, while magnesium is found in cocoa, samphire and almonds.

Are you curious what fruits and vegetables are the best snack for in between meals? Read that here in our blog on healthy snacks.

Enjoying sports

Good nutrition is also super important in combination with sports. If you don’t have enough energy available, you can’t put on your best performance. Moreover, eating well after exercise helps your body recover properly. For this purpose, among other things, it is important to eat enough protein. Proteins help recover and build your muscles after exercise. Proteins are found mainly in meat, fish, dairy, egg, legumes, tofu and nuts. We also have a high-protein protein smoothie in our assortment. This is ideal to take after exercise.

Learn more about what’s best for you to eat and drink before, during and after exercise. Healthy smoothies can also help you recover after a hard workout.

Also try our healthy juices

Vegetables are an incredibly important part of a healthy diet. They are bursting with vitamins and minerals that your body needs to stay healthy and fit. Yet few people eat enough vegetables daily. On average, the Dutch eat only 131 grams of vegetables per day (4). So there is a lot to be gained here!

To give you a hand, at Sapje we carry a variety of vegetable juices packed with vitamins and minerals. In addition to juices, we also have shots, detox cures, soups and smoothies. All full of fresh and organic vegetables! Perfect for increasing your daily vegetable intake in an easy way.

How can you use turmeric?

Turmeric has a long history and many different uses. Especially in Asia, the orange roots of turmeric have been used for centuries as part of a healthy lifestyle. Read on and find out what you can do with turmeric!

What is turmeric?

Turmeric is made from the roots of Curcuma longa, a plant in the Zingiberaceae family, which also includes ginger. Turmeric root is very similar to ginger root, familiar from our Ginger Shot, but is often slightly smaller than ginger and orange rather than yellow inside. Traditionally, turmeric root is first boiled or steamed before use. You also often encounter turmeric in powder form, in which case it is dried and ground. The taste of dried and ground turmeric is a bit bitter yet also sweet, with a warming effect. Thanks to the compound curcumin, turmeric powder is bright yellow; much more yellow than ground ginger.

Where does turmeric come from?

The natural origin of the Curcuma longa plant is in the tropical regions of South Asia. There are more than 130 known species of turmeric. In general, this plant needs warm temperatures, between 20 and 30 degrees Celsius, and good amounts of rain. Turmeric plants can grow about one meter tall. They have oblong leaves, but mainly the roots are used for consumption and other uses. Turmeric is associated above all with India, where people have used this spice for many centuries. Vedic texts nearly 4,000 years old already describe various uses of turmeric as an important spice in dishes. People also used turmeric as part of religious rituals and as part of an Ayurvedic lifestyle. Later, the use of turmeric spread throughout the rest of the world. Today, India is still the largest producer and consumer of turmeric. Almost all turmeric used worldwide comes from India.

What other names does turmeric have?

The name ‘turmeric’ comes from Sanskrit and is still used in many countries, including the Netherlands. However, we also use the name “turmeric,” and in supermarkets you will also come across turmeric in packages with the names “turmeric” and “turmeric,” which are derived from the Indonesian names. More information about turmeric in English can be found if you search for ‘turmeric’.

What is curcumin?

Turmeric contains several curcuminoids; dyes that make turmeric so yellow. Turmeric powder generally consists of just over 3% curcumin.

How are turmeric and curcumin used?

Curcumin as a dye

Curcumin is a very strong dye. It is widely used to color other foods, including butter and cheese, as well as desserts, cakes and sauces. You almost always find turmeric in curries, and in dishes with yellow rice. As a food additive, you can recognize curcumin under the E number E100. Soap and other cosmetics can also be colored with curcumin. You can recognize curcumin on a label under the INCI code CI75300. This dye is also used to dye fabrics. So watch your clothes when working with turmeric. The stains it makes in fabric you can hardly get out, if at all.

How to use turmeric in dishes

Turmeric is a very versatile ingredient for the tastiest dishes. For example, this warming spice shines in Asian dishes, such as this green curry masala with bottle pumpkin, or this sparkling chutney with apple and mango. Also try this delicious Moroccan harira! For lovers of nutritious and healthy soups, this spicy parsnip soup with turmeric is highly recommended. Golden milk or Turmeric Latte has been a popular drink among turmeric lovers in recent years. You make this comforting and healthy latte with warm, (vegetable) milk and turmeric, ginger and other warming spices. A great alternative to tea, coffee or hot chocolate!

How much turmeric can you eat per day?

No reference intake has been established for turmeric to date. If you use it as a kitchen herb, you will not easily eat too much turmeric, but do not overdo it. If you use turmeric as a supplement, stick to the prescribed dosage and if in doubt, consult your doctor; for example, if you are taking medication or suffering from health conditions. The use of turmeric is not recommended for children and women who are pregnant, as its safety for them has not been established with certainty. If you are considering taking supplements containing curcumin, keep in mind WHO (World Health Organization) guidelines. These recommend a daily intake of up to 3mg of curcuminoids per kilogram of body weight.

Try a turmeric juice

At Sapje, we also like to use turmeric. It is the main ingredient in our Kick juice, which also contains black pepper and lemon, among other ingredients.

7 tips to sleep better

Do you ever lie tossing and turning in your bed? Or wake up tired in the morning? Then you’re not the only one. Many people experience problems sleeping. But did you know that there are several things you can do to improve your sleep? In this blog we give you practical tips that you can apply to sleep better and wake up rested in the morning.

Why is sleep important?

You probably recognize it. After a night of poor sleep, you feel less energetic, are more irritable and concentrate a lot harder. Good sleep is crucial for your body to function optimally. Sleep not only helps you get through the day full of energy, but is also important for such things as your immune system, memory function, regulation of emotions and recovery of your tissues and muscles. An adult person needs about 7-9 hours of sleep per night(1). But not only is the amount of sleep important, so is the quality. The tips below can help you boost your sleep.

Tip 1: Provide a pleasant sleeping environment

A good night’s sleep starts with a nice sleeping environment. By making your bedroom as comfortable as possible, you ensure that external factors cannot affect your sleep. This starts with a good bed, with a comfortable mattress and nice pillow that suits your body and sleeping position. Also make sure your room is cool and dark enough, for example by using blackout curtains or a sleeping mask. Noise pollution can also hinder your sleep. If you sleep in a noisy environment, consider using earplugs. In summary, then, you can pay attention to the following points:

  • Comfortable bed
  • Pleasant temperature (between 16 and 20 degrees Celsius)
  • Dark Room
  • Avoid noise
  • Soothing decor

Tip 2: Create a sleep routine

Make sure you go to bed around the same time every night and get up around the same time in the morning, including weekends. This helps your body develop a regular sleep-wake rhythm. An irregular sleep pattern has been associated with reduced sleep quality in several studies(2,3).

Tip 3: Relax before sleeping

In the hour before you go to sleep, try to prepare for the night. For example, take a warm bath, read a book or do a meditation exercise(4,5,6). This way, your body and brain can settle down before you go to sleep. Especially during busy and stressful periods, this can potentially improve the quality of your sleep and ensure that you wake up more rested.

Tip 4: No screens before sleeping

When your eyes are exposed to a lot of light at night, it can negatively affect your sleep. This is because light can reset your internal biological (circadian) clock and inhibit the release of the sleep hormone melatonin(7, 8). This makes you less likely to fall asleep and the quality of your sleep is lower. In particular, blue light with a wavelength between 450 and 480 nm has this effect. The screens of our phones, laptops, tablets and TVs, for example, emit relatively large amounts of this blue light. Therefore, try to use as few screens as possible in the hours before you go to sleep.

There is evidence that using special blue-light-blocking glasses with orange lenses can reduce blue light exposure(9). Also, devices often have a night mode that you can turn on so that the screen emits less blue light. Still, the best advice remains not to use screens at all before sleeping. Other light intensities may have less impact than blue light, but they still affect your sleep. In addition, using screens often causes a lot of brain activity, which doesn’t help your sleep either.

Tip 5: Eat healthy and varied meals

What you eat also affects your sleep. In short, those who eat healthy sleep better. In addition, there are a number of specific things you can pay attention to in order to support your sleep:

Provide a good structure. An irregular eating pattern is linked to decreased sleep quality. Nutrition plays an important role in the regulation of your biological clock(10). A good structure helps your body determine when it is time to go to sleep.

Eat enough. Eating too much, as well as too little, can negatively affect your sleep quality. Make sure you listen to your body and eat when you are hungry.

Eat plenty of carbohydrates. A diet high in carbohydrates seems to help you fall asleep faster(11). However, it is important to make sure you choose enough carbohydrate sources throughout the day that are high in healthy nutrients, such as whole grain pasta, brown rice and potatoes.

Eat plenty of protein. A high protein intake can possibly also contribute to your sleep quality(12). Protein can be found, for example, in fish, meat, egg, legumes, tofu and nuts.

Eat plenty of fruits and vegetables. Fruits and vegetables are full of important vitamins and minerals that help your body stay healthy and fit. Vitamins C and B11 and the minerals iron and magnesium also help reduce fatigue.

Tip: Do you struggle to eat enough fruits and vegetables daily? Then our vegetable juices, including our red beet juice, are really for you. Also check out our ginger shots, such as our ginger shot, or our smoothies and soups. In fact, these are packed with fresh organic fruits and vegetables. After preparation, they are immediately frozen in the shock freezer to ensure optimal preservation of the healthy nutrients.

Tip 6: No caffeine before sleeping

Caffeine can make you less likely to fall asleep and lower the quality of your sleep(13). Coffee is the main source of caffeine, but other drinks such as cola and energy drinks also contain caffeine. And did you know that chocolate, for example, also contains some caffeine? On average, it takes about 5 hours for your body to process half the amount of caffeine. But this varies a lot from person to person. Do you notice that you feel a lot of effects from caffeine? Try not to take any more caffeine after 12:00 noon. This way you make sure your body has processed all the caffeine before you go to sleep.

Tip 7: Enjoy exercise and getting outside

Exercise and time spent outside daily also seem to influence our sleep. Several studies show a positive relationship between regular exercise and physical activity and the quality of your sleep(14). Being outside during the day may be beneficial to your biological clock(15). Exposure to daylight contributes to your sleep-wake rhythm. So go for a walk on your lunch break or meet up with a friend on the tennis court.
