1 . The African grey parrot’s ability to talk and mimic sounds makes it a charming companion. African grey owners often report that their greys oftentimes talk in context and can understand their people’s emotions (情感). The African grey parrot is not just a top talker - this bird is also known for its extreme intelligence, which gives them the name “The Einsteins of the Bird World”.
The bird is medium-sized, dusty-looking and almost pigeon-like. It has a bright red tail, intelligent orange eyes, and a stunning scalloped (扇形的) pattern to its feathers. Their diet in the wild consists mostly of nuts, seeds, fruits, and leafy matter.
At home, African greys need plenty of toys that challenge their intelligence, such as food searching and puzzle toys. Nutri-Berries by Lafeber Company are a perfect choice, which, with a balance of grains, seeds and other nutrients in the shape of a berry, encourages African greys to hold, bite off, and even play with, just as they do in the wild.
African greys seem especially affected by stress and disturbing noise in their environment and can be put more at ease by placing one corner of the cage against a wall as opposed to in the middle of a room.
African grey parrots are more likely to suffer from lack of Vitamin-A/beta-carotene, and therefore benefit from eating vegetables high in beta-carotene, such as cooked sweet potato and fresh kale. Lack of Vitamin-D is another concern, especially for greys on a poor diet. Offering a balanced, pill-shaped diet, such as Nutri-Berries, helps prevent vitamin and mineral shortage.

2 . When it comes to losing weight, many individuals know that the correct amount of exercise paired with healthy eating is the way to go. However, this doesn’t stop individuals from employing other small strategies into their routines to help the weight come off faster. The cold water technique uses the understanding that our metabolic (新陈代谢) rate will need to be increased in order to warm up the water we have consumed.
In 2003, a German research team chose to study fourteen participants and found that when they consumed ice water, they were able to increase their caloric consumption. According to the study, this consumption was increased by about 30% for over an hour, resulting in a 100 calorie burn per day with two liters of cold water. Now two liters of cold water a day is quite a lot to consume but for 100 calories burned a day, that’s a pretty major benefit considering how much exercise it takes just to burn 100-200 calories off. Unfortunately, later on, it was found that the way the study measured caloric consumption was flawed(有缺陷的) and that there wasn’t actually a 30% rise in metabolic rate but rather a very small statistical rise in calories spent.
Your body will work to bring any cold water that you consume up to the internal temperature through your metabolic system. It’s like when you place an ice cube into a warm drink, the drink will use up the energy to melt down the ice cube. Your body will use up the energy to heat that water up to match the environment within your body.
Drinking ice cold water should not replace healthy eating or exercise, but it can be used to help you burn away some extra calories.
