Mushroom is a Green food. Green foods are safe to eat as a regular part of a diet.
Guideline related quotes related to Non-Starchy and Green throughout Geoff Bond's publications.
Eat at least 2 3/4 lbs of mixed salad and vegetables per day, consisting of "Green-Green” and “Green” foods. Of these, at least 3/4 lb should be mixed salad. Also include at least 5 cups of “Green-Green” leafy vegetables or 2 1/2 cups of other vegetables per week. ~Paleo in a Nutshell p.102
Specific references to Mushroom throughout Geoff Bond's publications.
our ancestors knew they were living in a dangerous, treacherous, and unpredictable jungle. They had the skills to survive: They knew how to circumvent a hungry leopard and which mushrooms were poisonous. This book teaches you the skills to survive in today's "supermarket jungle." ~Paleo in a Nutshell p.3
It is quite easy really to achieve six servings by eating one big salad every day with all the usual ingredients we think of as salad vegetables: Tomatoes, lettuce, radish, cucumber, mushrooms, onions, and so forth. ~Paleo in a Nutshell p.48
Conforming non-starchy, colored plant foods are foods that are low-glycemic, rich in micronutrients and fiber, and harmless with regard to anti-nutrients and antigens. Broadly, they include most salad foods, such as lettuce, onions, cucumber, radish, and mushrooms, and they also include colored vegetables, such as broccoli, green beans, bell peppers (sweet peppers), and Brussels sprouts. These are considered "Green-Green," "Green," and "Green-Amber." Under "Green-Green," we have separated out the vegetables that have the high concentrations of background micronutrients that our ancient ancestors delighted in. You can have unlimited consumption of these foods, and the ideal is up to two pounds (900 g) per day. ~Paleo in a Nutshell p.62
Old-Fashioned Haddock Breakfast. This used to be a good standby in many parts of the English-speaking world. Many people are old enough to remember, perhaps, when their grandparents used to eat like this. They would lightly poach a piece of haddock (or kipper or any other appropriate fish) in simmering water for about five minutes. They would accompany it with lashings of sauteed onion, grilled tomatoes, and mushrooms. ~Paleo in a Nutshell p.88
Eating in fast-food restaurants is a little harder. Find a salad, if you can; discard the packet of salad dressing, unless it is simple oil and vinegar. Consider carrying a bottle of your own vinaigrette. Or eat the all-day breakfast: Eggs with tomatoes and mushrooms (without bread or roll) are acceptable, but avoid the bacon, sausage, hash browns, toast, waffles, syrup, and muffins. It is not ideal to eat the processed meat in fast-food restaurants, but if you must, order the burger (no cheese) or grilled chicken sandwich and throw away the bun. ~Paleo in a Nutshell p.90
The vegetables from above ground cover a huge range of plant parts: stems, such as asparagus from the Mediterranean and kohlrabi from Europe; buds, such as Brussels sprouts from Belgium; leafstalks, such as celery from the Mediterranean and rhubarb from Asia; leaves, such as Europe's cabbage, lettuce, and spinach; immature flowers, such as cauliflower from Europe, broccoli from Turkey, and artichoke from the western Mediterranean; immature fruits, such as eggplant from southern Asia and cucumber from northern India; mature "vegetable-fruits," such as tomato from Peru, avocado from Central America, and bell pepper from the Andes; edible bean pods, such as runner beans from tropical America; and edible fungi (mushrooms) from just about everywhere. Of course, today, these plants are grown all over the world, wherever farmers can produce them economically. ~Deadly Harvest p.56
This overview of the science gives us the main signposts, but when it comes to food choices, we need to have a knowledge of the details as well. Our ancient ancestors had the skills to survive in the jungle. They knew which mushrooms were poisonous and when a tree would be fruiting. We will need to learn the same level of skill when navigating our way through the supermarket jungle today. However, we can finally declare that we have enough evidence to describe the basic specification for the diet that is right for the human species. That is, we can now write the "Owner's Manual." ~Deadly Harvest p.134
Eggs Any Style. Omega-3-rich, free-range eggs any style are fine to start the day. Make a hearty vegetable-filled omelet or grill some tomatoes and mushrooms with eggs any style. Don't forget that plant food should form the major part of the meal, and no backsliding— definitely no bread. ~Deadly Harvest p.161
Eating in fast-food restaurants is just the same, only harder. Resign yourself to ordering the burger and throwing away the bun. Find a salad, if you can, but discard the packet of salad dressing (consider carrying a bottle of your own vinaigrette). Or eat the all-day breakfast: eggs with tomatoes and mushrooms are acceptable, but avoid the sausage, steak, hash-browns, toast, waffles, syrup, and muffins. ~Deadly Harvest p.164
