Saturated fats are typically found in animal products, like dairy and red meat, and tropical oils. Saturated fats are liquid when hot, but begin to solidify at room temperature – think bacon grease – so they
Monounsaturated fats, sometimes called MUFA, are omega-9 fats. They are known for their role in heart health and their presence in Mediterranean-style diets. These famous fats may lower blood pressure, triglycerides, total and “bad” LDL cholesterol, and diabetes risk. Sources include avocados,...
根据空后内容“When ketones are present, the body transitions into a metabolic (新陈代谢的) state called ketosis. People sometimes experience dry mouth or feeling overall unwell when they start the diet -- symptoms of ketosis called the “keto flu”. But once your body adapts, those symptoms ...
When working with polyunsaturated fatty acids, sometimes it is more convenient to count from the methyl end. The terms omega (o) and n are sometimes used for this purpose. The notation C18:2n-6 signi?es linolenic acid, an 18-carbon chain fatty acid with two unsaturated positions, the ?
LDL (and especially VLDL) has been called "bad cholesterol" because it can become so overloaded with fats that the fats are dropped on blood vessel walls rather than carried to the cells where they are needed. LDL could also be called "good", because LDL supplies cells with fats needed ...
Fats are organic molecules made up of carbon and hydrogen elements joined together in long chains called hydrocarbons. These molecules can be constructed in different ways, which creates different types of fat and their unique properties. The molecular configuration also determines whether fats will be...
Omega-3 fats are an important type of polyunsaturated fats that our body cannot make, so they must come from food. Omega-3 fats consist of three different fatty acids, one of which is called docosahexaenoic acid (DHA). This is one of the main building blocks of the brain. It is very ...
Other articles will deal in detail with most of these ANFs, which are sometimes called secondary metabolites. This chapter will consider the plant species involved and their interaction with animals and humans when they are eaten. The chapter will also consider briefly how the effects of ANFs ca...
Every carbon atom has the capacity to make four bonds with other atoms. Sometimes atoms will bond with other carbon atoms, and sometimes they bond with other substances, such as hydrogen or oxygen. Here we are largely concerned with the bonds between carbon atoms. ...
Fish is sometimes called “brain food” largely due to its high omega-3 content. But there are many concerns about high levels of mercury, PCBs, pesticides, and other contaminants found in fish. Fortunately, a handful of fish arehigh in omega-3sandlow in mercury— Alaskan salmon, herring,...
