All fats raise cholesterol levels.

False. Predominantly trans- and saturated fats, while unsaturated fats can actually have cholesterol-lowering effect]]> 2021-06-23 02:45:52 UTC https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853241 A weighty issue jzha07991 https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853242 True or false? Give reasons.
Cutting out carbohydrates always leads to weight loss

False. Weight loss achieved through a calorie deficit, which carbs technically are not too concentrated in calories. Fats/alcohols have higher calorie amounts.

Is there any truth to this? Evaluate.
20 major amino acids. In plant based you don't get the entire complement. Be careful of iron levels and B12 levels.

You can get enough proteins generally from plants, but animal plants have all proteins made of all 20 amino acids. Thus achieving complete required protein intake is easier via animal intake, but it's not impossible to get required protein intake from a range of plant sources.]]> 2021-06-23 02:45:52 UTC https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853243 Energy for your brain! jzha07991 https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853244 Which nutrient is the brain almost entirely dependent on for energy? What would this mean for very low-carb diets?

Glucose.
Keto/super-low carb diets sometimes have brain fog. Thus the brain resorts to glycogen rather than readily available glucose.]]> 2021-06-23 02:45:52 UTC https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853244 High protein pee jzha07991 https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853246 We love to take protein to fuel our muscle growth. However our muscles can absorb only a certain amount of protein, the rest is used for other functions or pee'd out.
Have a look at the abstract of the study in this link and get an idea of how much protein you should be eating per meal for maximal muscle growth (assuming you consume 4 meals a day). Note it down here.

Ideally 20g per day per average adult. Higher amounts generally lead to oxidation of the amino acids when they can't be stored in the muscles already at their protein storage thresholds.]]> 2021-06-23 02:45:52 UTC https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853246 Fats make you fat jzha07991 https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853248 Do they though? Assess this statement.

Not this simple. Everything must be taken in moderation.
Fats alone are not the cause of being overweight.

All carbs, proteins and lipids can contribute to your total calorie intake, which is the leading indicator, when netted against calorie burning for body functions, determines weight.

This includes the breakdown of your food into molecules that can be absorbed into your blood.
Name an enzyme that takes part in your digestive process. Hint: enzymes almost universally end with the suffix "ase".

Lactase - breaks down lactose
Protease - break down proteins.

Why is fibre important for your digestive process if it can't be digested?

Provides food for microbiome situated in large intestine. Provides bulk for your stool once water is extracted.

Fructose and Galactose are the other two monosaccharides.

Zero trans fats ideally
Minimal amounts of saturated fats
Larger proportion of total fat intake to be mono/poly-unsaturated fats.]]> 2021-06-23 02:45:52 UTC https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853265 Necessary for the absorption and transportation of these important vitamins jzha07991 https://padlet.com/jzha07991/7sh6hytl1cz7k4tf/wish/1620853266 Name a function of each of these vitamins
Vitamin A:

gene expression
– binding specific nuclear receptors

– cell differentiation
– embryogenesis

growth & development
reproduction (deficiency  infertility)
immune function
vision

– allows sight in dim light
– role in production of tears

Vitamin D:
Structural

– Provides framework for vertebral body – skeleton and teeth

Metabolic activity

· Membrane permeability

· Nerve conduction

· Muscle contraction

· Blood clotting cascade, in eg. interactions with Vit K

· Enzyme regulation

Second messenger – intracellular signalling – Ca regulates enzyme action by phosphorylation / de- phosphorylation

Vitamin E:
Antioxidant

• prevents lipid peroxidation

• protects cell membranes and plasma lipoproteins
- maintenance of cell membrane structural integrity

• regulate intracellular signalling and cell proliferation through Protein Kinase C

• anti-inflammatory effect

• stimulates the immune response

Vitamin K:
- cofactor for g-glutamyl carboxylase

o post-translational carboxylation of glutamate to g-carboxyglutamate so it can bind calcium
