Are You Deficient in Copper?
Copper is an important trace dietary mineral which fulfils many important functions within the body.
Many of the proteins and enzymes that perform essential metabolic functions contain copper. It is important for the growth, development and maintenance of bone, ligaments and many organs. It also works as part of the immune system to fight infections and can neutralize free radicals – molecules with unpaired valence electrons that can cause damage to cells in the body.
Copper is a constituent of the blood pigment hemocyanin in mollusks and crustaceans, and is involved with the production of hemoglobin in vertebrates, including mammals and humans. It is also important for keeping bones, muscles, nerves and the immune system healthy.
What Does Copper Do?
Copper has several important uses within the body. One of the most important roles is in the production of bone and connective tissue. It also works with iron to help the body to produce red blood cells. People who have a deficiency can suffer from anaemia and osteoporosis.
The human body has a homeostatic mechanism that deals with copper. This attempts to give the body a continual supply of copper while eliminating excess amounts of copper. Consuming too much or too little copper can lead to health problems, so it is always best to eat the correct amount.
Food Sources of Copper
Like many essential minerals, copper is available through both plant and animal sources. Many of these are compatible with the paleo diet, including liver pâté, which is probably the best source with just a 12g portion of liver pâté providing 100% of your recommended daily intake. Liver pâté is an amazing super-food!
As well as being a supposed aphrodisiac, oysters are also a great source of copper. Lobster and calamari are other good seafood source of copper.
Other important sources of copper include:
· Nuts, particularly cashew nuts
· Sesame seeds and tahini
· Pumpkin and squash seeds
· Sunflower seeds
· Prunes
· Sun-dried tomatoes
Problems Associated with Copper Intake
Whilst copper is an essential mineral that your body needs, it is also toxic in large quantities. An inherited condition, called Wilson’s disease, can cause deposits of copper in the liver, brain and other organs. These copper deposits can lead to the development of hepatitis, kidney problems and brain disorders.
Copper deficiency can be a major problem for the human body. As it is an essential ingredient for many bodily functions, having low levels can seriously affect your health. Anemia is a common side effect, due to the reduced rate of producing red blood cells. Osteoporosis can also result from copper deficiency and problems with the immune system.
As an important dietary mineral, it is important to consume your recommended daily amount of copper.

Paleo for Better Skin
I've read about so many people going onto a paleo diet and noticing significant improvements in their skin. With a few tweaks, eating this way seems to have helped a lot of people suffering from acne, eczema, spots, redness, blemishes and breakouts.
What causes skin problems?
It seems that a lot of issues are down to inflammation. Of course, grains are inflammatory, so removing them from the diet – and being very strict and vigilant, especially where gluten is concerned, will make a big difference.
Gut health and permeability also appear to be significant factors in skin. Heal your gut – and heal your complexion.
Hormones are another big factor. Eating foods like soy can interfere with hormones – so obviously following a paleo protocol (and ditching those legumes) will mitigate this issue.
Natural skin care
The chemicals in many of the commercial products are frightening. Lots of people on the paleo community swear by coconut oil.
Eat more fat
Getting over fear of fat seems to have helped many people with their skin issues. Try to get more fat in your diet – from good Paleo sources, of course.
Gelatin
Another paleo skin cure seems to be bone broth. Regularly consuming a high quality home made bone broth could be what is standing between you and beautiful blemish free, glowing, skin!
Liz Wolfe has produced a natural, paleo skin care guide, called “The Skintervention Guide“, so if you're still have problems with your complexion – and want to find a natural solutions, you can check it out here.

Low Protein? High Protein?
In case you didn't already know, dietary protein is essential for human health. Protein is used in the body to build and maintain new tissue such as muscle, hair, nails, skin, bone and blood cells. It is also required to create the enzymes for the body to carry out certain processes, such as the digestion of food; and neurotransmitters, which control your ability to carry out basic tasks (like thought and movement). US dietary guidelines recommend a daily intake of 45g per day for females, and 55g per day for males. In reality, you need much more to maintain optimum health, especially if you’re active. But just how much should you be taking in? And is it possible to consume too much?
Put simply, the amount of protein you need is unique to each individual. For a sedentary person, Many sources recommend around 1g of protein per kilo of bodyweight as a realistic amount needed to maintain lean mass. If you’re more active, you’ll be looking at around 1.5g – and if you’re lifting (and looking to increase lean muscle mass), between 1.8g and 2.0g per kilo of bodyweight is optimal. For example, a 70kg man training three times per week and looking to increase his muscle mass should be targeting between 130g and 140g of protein per day. That’s the equivalent of around 3 eggs, one chicken breast, a handful of almonds and one sirloin steak – so is by no means reaching into the realms of ‘forced’ protein.
Indeed, if protein forms the majority of your caloric intake, then you’re probably consuming too much. Fat should be your main source of energy, with between 15 and 25% coming from protein. Too much protein can create excess toxins in the body, and put a significant strain on the liver and heart. Not ideal.
Chances are, your Paleo diet already features a respectable amount of protein and you’ll probably be achieving your protein ‘target’ without even knowing it. Meat, poultry, fish, eggs, nuts and seeds are all good sources of this macro-nutrient. Amino acids, the building blocks of protein, are found in plants as well – albeit in various quantities. If a food contains all of the ‘essential’ amino acids, then this food is considered a ‘complete’ protein. As plant protein sources are normally lacking in at least one of the essential amino acids, they are usually considered as ‘incomplete’ protein. This is one of the reasons it is hard for vegans to consume adequate protein, and leads to them having to selectively combine foods to achieve a complete amino acid profile.
To conclude, it is probably much better you focus on the quality of the protein you are taking in rather than the quantity. Don’t worry too much about hitting a ‘target amount’ – simply build each meal around a high quality protein source like red meat, poultry, fish or eggs. Consume extra if you’re active, especially on training days. But don’t stress yourself out about it; you’re much more likely to be getting a solid amount of protein each day simply by eating real foods.
