I'm 70 years old in great health and I blend healthy fruits and vegetables (12 party cups in all) every couple of weeks.
My 6 cups of blended salad products consist of homegrown hot peppers (Habanero, cayenne, and Jalapenos), garlic, onions, Tumeric, oregano, rosemary, basil, arugula, spinach, tomatoes, feta cheese, salsa, carrots, various nuts, sea salt and pepper, oil and vinegar, black olives, chicken broth, etc… these amounts can be adjusted to taste and what food products that you want to freeze before they go bad.
First pre-blend (I use a small Magic Bullet blender to do this… first with the chopping blade and next with the flat blade) the peppers and garlic, after adding a little of the blending base liquid… for the salad blends, I use chicken broth and fruit blends I use Almond Milk. I do this pre-blending for both salads and fruit blends. Hot peppers and garlic are the most important foods to health and wellbeing, imv, and diluting them down with fruits and salad products (organic or home grown if possible) makes them tolerable to drink daily. Thru the year I freeze fresh produce and peppers, during the growing season, so I have plenty on hand for the year.
My 6 cups of blended fruits usually consist of blueberries, kiwi, strawberries, apple, flax seed and nuts, almond milk, bananas, grapefruit, cherries, yogurt, granola, pure raw honey, etc. Of course don't forget the most important hot pepper and garlic blend, as mentioned in the previous paragraph, to the high speed large blender.
Once blended up in the large blender just pour up in cups, cover cups with saran wrap, and freeze it. Just take out one cup every day or so, the evening before to allow to thaw out overnight. I always say go with the healthy foods first and then make them as good tasting as possible... enjoy!
