Green Smoothies & Calories/Sugar/Fructose/Carbs
Calories: Many people ask me if a 350-calorie green smoothie has too many calories. The answer is no, not if you’re drinking your green smoothie as a meal (which is what I do and recommend). Green smoothie meals should have no fewer than 300 calories. If your daily calorie requirements are 1600 per day, and you eat three times per day, you’ll need 533 calories per meal.

What I Eat When I Am Not Drinking Green Smoothies
I am frequently asked about what other foods I eat, besides green smoothies. I do not follow or recommend a smoothie-only diet.
Detox & Cleansing
All fruits and vegetables facilitate detox. Be sure to use only organic ingredients in your smoothie recipes, avoid animal products, dried foods and additional sweeteners during your detox and find a workout routine that works for you. When it comes to making the “ultimate” detox green smoothies, I use dandelion greens and citrus such as orange, grapefruit, lemon and lime.
Here’s some tips on how make a deliciously potent detox smoothie.

Buying, Storing & Keeping Greens Fresh
How Long Will Green Smoothies Last In the Fridge: Green smoothies will stay fresh in the refrigerator for up to 24 hours, but you will lose some nutrients as it sits in the fridge. It will also not taste as fresh after the first day and water separation may occur. Some people make up a big batch of smoothie and drink it over 2 to 3 days. Personally, we don’t like the way smoothies taste after the first day. Fresh is best!
Organic vs. Non-Organic: Find out which fruits and vegetables you should always buy organic, and which ones you don’t have to.

Do I have to put greens in my smoothies?
You don’t have to, but we highly recommend that you do! Greens are rich in calcium, iron, magnesium, vitamin A (as beta-carotene), C, K and many B vitamins. They are also rich in chlorophyll and antioxidants. Most people do
not eat enough leafy greens each day so blending them with fruit in a smoothie is the best way we have found to sneak more greens into our diet.
If adding leafy greens to a fruit smoothie just seems too alien of a concept, or even disgusting to you, try it out by adding just one small handful of fresh baby spinach to a fruit smoothie. You won’t taste it! Once you’ve taken this
first step, add another small handful and work up to 2 handfuls of leafy greens per smoothie. Before long, you’ll be blending an entire bunch of kale or dandelion greens!

How many green smoothies should I drink in a day?
I try to have at least two 32 ounce (1 liter) of green smoothie every day using an entire bunch of leafy greens in each smoothie. Most often, I drink up to 70 ounces of green smoothie in a day – one at breakfast and one at lunchtime. They are about 400 to 500 calories each.
If you are starting out, this will probably be too much for you. Start with a 16-ounce smoothie and work your way up to a quart. Then go from there. We don’t necessarily advocate or recommend a liquid, smoothie-based diet.
For us, it’s purely for convenience. You can get the same or similar nutrition by drinking one 16-ounce green smoothie in the morning and having a large salad or vegetable meal at lunch.
How much is a “bunch” of greens?
When I say a “bunch” of leafy greens, I am referring to how you would typically purchase them in a supermarket – such as several stalks of kale, dandelion or Swiss chard bundled together. Typically, there are about 3-4 cups leafy greens in a bunch when chopped.
A bunch can also be an entire large head of green/red leaf lettuce or romaine. I would consider 2 heads of baby bok choy or 3 heads of baby romaine lettuce as one bunch of greens.
When it comes to bagged or packaged salad mix, such as spring mix or fresh baby spinach, I consider a “bunch” to be about 4 cups (or handfuls) of packed or chopped greens.
My general recommendation is to consume about one bunch or equivalent of a variety of leafy greens per day (up to 2 bunches per day if you are on a raw or mostly raw vegan diet in order to obtain sufficient minerals).
Why do your green smoothie recipes not have milk or yogurt?
None of my green smoothie recipes call for milk or yogurt because dairy is not necessary for making a rich, creamy smoothie. Dairy doesn’t facilitate detoxification, it contains hormones and promotes animal cruelty (as well as providing young calves for the inhumane veal industry). It is easy to make a thick, creamy smoothie using the right types of what I call “base” fruits like banana, mango and durian. Read Smoothie Making 101 to find out how to make a creamy smoothie using fruit as the base.
If you still want to use milk, try these nut milk recommendations or make your own. You can find brands at most supermarkets that are fortified with calcium and vitamin D as well. They are much healthier alternatives to cow’s milk.
Is it okay to use frozen fruit in a smoothie?
I regularly freeze strawberries and bananas when they are on sale and I frequently buy frozen wild blueberries.
Freezing does destroy some of the nutrients but not enough to really worry about as long as you eat plenty of fresh, ripe, non-frozen and raw foods. Try not to use too much frozen fruit, though. Drinking and eating ice cold (or steaming hot) foods can interfere with digestion or cause damage. It’s best to drink a green smoothie at room temperature, but if you do not like to, then add a few frozen berries to chill it slightly.
