Saturated fat protects you from CVD. If you take the seven countries in the world that have the lowest saturated fat intake and the seven countries that have the highest saturated fat intake - Dr. Malcolm Kendrick has pointed out: “Every single one of the seven countries with the lowest saturated fat consumption has significantly higher rates of heart disease than every single one of the countries with the highest saturated fat consumption.” (From World Health Organisation (WHO) data.)
Cholesterol is your friend - not your enemy. Higher levels of cholesterol relate to lower levels of cardiovascular disease death - more so in woman than men. For overall deaths by any cause the relationship between higher levels of cholesterol and lower rates of death is even more significant. So for all the data available in the world - higher cholesterol equals lower mortality and lower cholesterol equals higher mortality. WHO data analysed by Zoë Harcombe Carbohydrates are your enemy - not your friend. Carbohydrates are useful for turning your body into hibernation mode. They help you store energy in the form of fat to tide you over the lean periods. Continued exposure to them, however, can cause you to become insulin resistant and you may find yourself developing metabolic syndrome, one symptom being increasing weight as you get older. In nature availability of carbohydrates is normally limited to certain times of the year. This is what our evolution has been used to. Modern civilization has upset the balance and now we can get fruit all year round. Moreover, we can now produce carbohydrates from plants that would normally only be digested by birds. Certain phytochemicals in these plants are playing havoc with our metabolic pathways. Some animals have evolved to be able to successfully handle these plants as food. Not so for humans who have been only exposed to them for 2,000 - 10,000 years. (Not much time in the evolutionary scheme of things.) There are no studies or experiments that show we need to have carbohydrates in our diet. On the other hand there are examples of civilizations that have been able to survive with little or zero carbohydrates from cradle to grave. See the Inuit and the Masai.
Modern dietary trends and modern lifestyles are causing the inflammation that leads to modern diseases of obesity, diabetes, cardiovascular disease, dementia and cancers. One mechanism that exists in our physiology to protect against these is the ability to produce cholesterol. Damage to our body is repaired by cholesterol. Our body will create cholesterol as it needs to and eating foods that are high in fat or cholesterol has no significant impact on this process. If our levels of cholesterol are high then the body has suffered, or is suffering, damage somewhere. Saturated fat in the diet does not cause fat build up in the arteries. Instead it gives us a fuel that we can burn quite efficiently and that naturally signals the body that we've got enough. Carbohydrates in the diet cause blood glucose to go up, this causes the pancreas to produce insulin to deal with it. Insulin puts cells into glucose burning mode and turns off ability to burn fat
It has been found that people with heart disease may have high levels of cholesterol. Is it logical to assume that cholesterol is causing heart disease or more logical that heart disease is causing cholesterol synthesis?
Statins interfere with the body's natural mechanisms for healing. Mortality from CVD has not been shown to be effected by use of statin drugs. All cause death is higher among those that more frequently use statin drugs. Statins simply reduce the amount of cholesterol produced by the body and therefore reduce our ability for self-healing. On top of that they are associated with side effects such as memory loss, sexual dysfunction, severe muscle aches, cataracts and diabetes"When the completed, 30-year data from the study was analyzed, in most age groups high cholesterol wasn't associated with more deaths." "Three-quarters of people having a first heart attack, for instance, have normal cholesterol levels. " "for older people, deaths were more common with low cholesterol." "Even for heart patients, a group in whom the benefits of statin drugs are broadly accepted, 80 people have to take the drug for one life to be saved. And just one in 40 will be spared from a heart attack. For these scraps of hopeful benefit, there is a price: the drug will give one in every 50 diabetes."
Do Humans Need to Eat Carbohydrate?
"The lower limit of dietary carbohydrate compatible with life apparently is zero, provided that adequate amounts of protein and fat are consumed."
"The minimal amount of exogenous and endogenous carb is dependent upon the brain (100-140 g glucose/d)."
"After ketoadaptation, about 80% of the CNS energy can be derived from ketones, leaving 20-28 g glucose /d."
"Endogenous glucose production rate: 2-2.5 mg/kg/min ~ 2.8-3.6 g/kg/day. In a 70 kg man, this represents 210-270 g/day."
