Fats and Omegas (Friday, 10st 8 1/4)

I finally started on The Greek Doctor’s Diet. I’ve had my mind blown by my sheer ignorance about fat.

A fatty acid is a long hydrocarbon chain capped by a carboxyl group (COOH). To make a fat molecule, you bind together three fatty acid chains with glycerol.

Saturated fat is solid at room temperature whereas saturated is normally liquid.

In saturated fats like the palmitic acid, the carbon atoms are equally filled with hydrogen, i.e. saturated with hydrogen. The oleic acid is not saturated – some of the hydrogens are missing.
The saturated fats are supposed to be bad, because they cause arteriosclerosis. It looks like this hasn’t actually been proven though, but it’s easy to believe as most saturated fats do look likely to clog arteries.

Chocolate, cheese and processed meats are saturated fats.

Unsaturated fats are salmon, almonds and avocados (all very tasty – have added them to my shopping list).

I’ve never wondered why there is Omega-3 and Omega-6. They are both fatty acids that have an unsaturated bond in their chain. In Omega-3 the bond is in the third position.

Omega-6, says Greek Doctor, is less good, but you do need the raw nuts and seeds it’s extracted from.

Omega-3 is brilliant. It’s in oily fish, walnuts and pumpkin seeds (also added to my list).

Breakfast: Porridge with crushed malted barley.

Lunch: Chicken leg and salad.

Drinks: Teas. Coffees.

Snack: Biltong from the South African shop in Thatcham. Slice of cheese.

Dinner: Chicken leg with salad.

Fruit: Pear.

Happy things:

  1. B chuffed with the Biltong.
  2. Enjoyed learning about fats.
  3. Really enjoyed the chicken and salad.

 

Evening snacking: some more Biltong. A few crisps and peanuts. Had Elderflower cordial with sparkling despite it being bad for me to compensate myself as B and D were having a drink.
