Fat Doesn’t Make You Fat

Spread the love

Fat is absolutely vital to consume. Why was there ever a low-fat craze? We are clearly seeing now that low-fat or no-fat diets are not healthy at all. Fats are essential and we need them for many functions in the body, so there is no reason to be afraid of them. Of course, if you eat a whole jar of nut butter that may cause a few problems so just be reasonable. There are two main types of fatty acids that can change your health for better or worse. Knowing the difference is an important part of understanding why fat is healthy. 

Fat is Healthy

What does fat do? It has many important roles in the body.

  1. Vitamin Absorption
    • Vitamins A, D, E and K all need fat to be absorbed. These are very important and cannot get absorbed into the body without fat. These vitamins are also stored in fat cells.
  2. Satiety
    • Keeps us full because they are heavy and calorie dense. This helps prevent overeating
  3. Energy
    • If glucose is not available, the body will use fat.
  4. Brain Development and Nerve Function
    • Nerve cells are insulated with fats and that insulation is important for proper communication.
    • The vitamins listed above, especially vitamin D, are shown to be important for cognitive function and are only absorbed through fat.
  5. Hormones
    • Sex hormones need fat to be properly regulated. For example, underweight women get their menstrual cycle later or not often enough.
  6. Cell Membranes
    • Your body is quite literally ALL cells. Every cell membrane needs to be properly built so the appropriate particles can or can’t pass through. If this does not function properly, you can run into many problems like nutrients not being absorbed correctly.
  7. Curb cravings – this is my personal recommendation
    • A spoonful of almond butter or other fatty snacks will make your cravings go away but don’t overdo it.
  8. Pregnancy development
    • It is very important for pregnant women to eat healthy fats to help with fetal brain development

Essential Fatty Acids (Omega-3 and Omega-6)

Omega-3 and Omega-6 are essential fatty acids (body can not make on own, must get from diet) and both are important for our health. It’s all about the source.

Omega-6’s are technically bad, but that is due to American’s current diets: vegetable oils, soybeans oils, margarine and the fats in processed foods or fried foods are the primary source. Oils that come from sources that are not fats to begin with cause problems due to over processing. These inflammation causing foods can lead to high blood pressure, heart disease, arthritis, depression, osteoporosis, among other conditions. Omega-6’s cause inflammation is consumed from a poor source. Omega-3’s are anti-inflammatory. There should be a balance of both of these from good sources as they both help with the important roles in the body.

Here’s an example of a processed food. Mayo is mainly soybean oil which is an unhealthy fat. Fat is healthy if you can find a better version with no soy or canola oil.
