In East Asian countries, people often drink unsweetened tea. Tea is not insanely bitter like coffee, so I think tea would probably be more popular than coffee for that reason. If tea is not available, then you can substitute tea with warm water. It's just a warm beverage to go with the meal - a lot better than the sugary fruit juice or soda.
2. Rice as Staple Food
Do you hate to cook? Try the Indian and East Asian diet then! Cooking rice is completely brainless, if you have a rice cooker. Even if you don't have a rice cooker, you just need to know that cooking rice requires a 1:2 rice-to-water ratio. If you have rice in your pantry, then you'll know that you always have something to eat! That's why it's called staple food. The main purpose of the staple food is to form the basis of your diet, so that you don't starve yourself.
3. Fruits as Desserts
Why settle for ice cream sundae, which is loaded with sugar, or chocolate cake, still a lot of sugar, when you can have something sugary and nutritious at the same time? Have a piece of fruit for dessert!
4. No Dairy Products
While Indians do have their paneer cheese, East Asians traditionally don't have any dairy products in the diet. If you have a milk allergy or are lactose-tolerant, then adopting an East Asian diet is the way to go. If you don't have a milk allergy or lactose intolerance, then you may find cheese-making kind of tricky and slow; and you aren't willing to buy store-bought cheese because store-bought cheese is not cheap or loaded with salt; and store-bought yogurt and ice cream may be loaded with sugar. You might as well just drop dairy products altogether, unless you own a lactating cow or goat and don't have any other food to eat.
5. Versatile Use of Soybeans
I think most Americans know of soymilk and soy sauce. What's not sold in mainstream American supermarkets is the soy pulp (the solid residue from the soymilk production) and the soybean curd (the thin film that floats on top of the boiling soymilk). Both are edible and sold in hyphenated American supermarkets. It is also possible to make soymilk at home and consume every bit of the soy. Sadly, this English-speaking tutorial on how to make soymilk suggests that you should discard the pulp, if you have no use for it, and the tofu skin. Please do not discard them! Those are perfectly edible! If you eat them, then you'll realize that soybeans are much more versatile than, say, milk, where the whey liquid is discarded in the process of cheese-making.
6. Large Farmed Animals Are Not Efficient
Raising large farm animals for meat is not efficient at supplying food, if you consider the size of the human population. Animals at the top of the food chain should have fewer numbers than animals at the bottom; otherwise, the whole ecosystem will collapse because the numerous superpredators (humans) are gobbling up everybody else. Humans must lower themselves in the food chain and eat like chickens, having a diet rich in plants and bugs. Although bugs are seriously considered for future food security, for the sake of this myTake, I am going to remove bugs, because of the cultural taboo that readers may have of entomophagy and because of the tricky issue of classifying bugs as "meat" or not. Eating a vegetarian diet would spare the lives of these large animals - the chickens, ducks, turkeys, pigs, and cattle. Including fish and seafood in the definition of meat, a vegetarian diet would spare the lives of the creatures of the sea and recover populations.
7. Being Top Predator Is Not A Good Idea
Being a top predator is not a very good idea, when you consider the fact that mercury-contaminated water will just travel up the food chain and ultimately reach humans. Since humans eat fish because they think they will get omega-3 fatty acids, in reality only wild-caught fish have omega-3 fatty acids because they eat the algae that makes omega-3 fatty acids. Now, the world's oceans are already depleting, and wild-caught fish are always on the expensive end. So, a good source of omega-3 fatty acids is a head of romaine lettuce. Eat a lot of romaine lettuces. Eat them like a rabbit, and they will allow you to breed like one, because you have reduced your status in the food chain from a tertiary or secondary consumer to a primary consumer.
