1) The 25 OHD tests exclusively Vitamin D levels in your blood. NG is nanograms and MG is milligrams. A nanogram is one thousand millionth of a gram. A milligram is one thousandth of a gram. Vitamin D is very powerful and like testosterone only needs to be in concentrations of nanograms in the body. Your results will be in nanograms and you want to be at 50ng or more. Toxicity does not occur until 100ng and higher.
2) Don't be angry with yourself. You know what you are taught. Western medicine first and foremost is a business. Business needs profits. Matching drugs to symptoms creates more business. While many people in medicine like yourself have good intentions, the industry you are in is not always operating that way. I believe antibiotics and anti-virals are cases where medicine is trying to do good for the sake of good, for example. As they say "The road to hell is paved with good intentions." This is why I believe more in Functional Medicine and how to use proper nutrition to address and prevent illness not drugs. All the studies and recommendations coming from the government and AMA are banking on the ignorance of the general public to trust all they say as gospel truth and that any alternative way of thinking is incorrect. As they say "Ignorance is bliss". If people took ownership of their health, did their own research, and came to their own conclusions, Big Pharma would be in trouble. They therefore have a vested interest to make sure the public stays in the dark as to the true causes of disease and they condition us to look only for symptom relief not cures. Just watch your average drug ad ---- it always ends with "ask your Doctor" and they always try to distract you with pretty music and pretty pictures while they disclose all the side-effects of the medicine which fortunately they are required to do by law. If they had their way, the side effects disclosures would be limited to the insert in the packaging.
3) High triglycerides (which come from fructose metabolism and alcohol metabolism) combined with high blood glucose (which comes from Type II diabetes) is what causes the damage to the Endothelium in the artery AND oxidizes your LDL cholesterol. The actual plaque is made up of cholesterol, immune cells, and clotting factors. This is why LDL and cholesterol get implicated as causing heart disease and artherosclerosis and sold to the public accordingly. By convincing you this is the case, it is easy to sell Statins and Metaformin and all the other drugs they have to address cholesterol and blood glucose issues and which must be taken for life.
High triglycerides lead to non-alcoholic fatty liver disease (NFLD) which is the most prevalent liver ailment in the U.S and occurs in people of all ages who eat the typical American diet loaded with high fructose corn syrup and other useless food additives. If your triglycerides are low and your HDL is high, this is indicative of non-oxidized LDL so no real need for an LDL particle test.
The arterial disease can be reversed or at least stopped by changing your diet, exercising, and losing weight. High HDL (above 50) also can help as this brings excess cholesterol or unused cholesterol back to the liver to be processed. The body has the amazing power to heal itself when given the proper nutrients. This is no different than smokers who smoke for decades, stop, and then their lungs return to almost 100% pre-smoking function and capacity. The same can be said for arterial plaque. This is the one case where you do need to limit dietary cholesterol until the situation has been rectified and the body returns to normal cholesterol function and metabolism. This could take up to a year. The bottom line is the body does not need cholesterol from food as the liver manufactures 75% of what is needed. The cholesterol in most foods is not in a form the body can absorb. Eating lots of fiber also aides in preventing over absorption and helps the body eliminate excess dietary cholesterol in the feces. It is not bad to have fiber limit cholesterol absorption. The human body is all about balance and every process has a feedback loop. The liver senses blood cholesterol levels and if they are too high due to dietary intake it cuts back its own production. Similar to how taking steroids shuts down the testes - the body senses high testosterone levels in the blood and tells the testes to stop making any. The rare exception where this cholesterol feedback mechanism doesn't work is with a genetic trait that runs in entire families called "hypercholesterolemia". In this rare case Statins can help because people with this condition continue to produce cholesterol regardless of blood levels.
4) A Vegan diet is healthy but has some limitations - it is very low in B12, low in complete proteins, and low in Omega 3 fats. However, having a diet that focuses more on fruits and vegetables (Mediterranean Diet, Vegetarian, etc) does improve cardio-vascular health for those with EXISTING conditions. A diet composed of non-processed, wholesome foods from all food groups - vegetables, fruit, meat, dairy, nuts, grains - also maintains health and prevents disease states like heart disease and cancer. The choice of what you want to eat is yours but all this fanatical press about one diet being better than another is rediculous. In my view, any diet that eliminates or restricts a wholesome nutrient or food type is not going to be as beneficial from a micro-nutrient perspective. This is why Vegans need B12 supplementation because it can only be had from animal sources and is critical to health. This is why I don't believe Veganism is sustainable. Regardless, it is a personal choice and I have no issue with how someone chooses to eat as long as they don't try to force it on me.
5) Carb-cycling can be done very easily. I do higher carbs/lower fat on workout days and higher fat/lower carbs on rest days. Protein remains constant. It is the easiest way to do it. There are several interations but I find it is just easier and more straightforward to do it as I have described. It does mean you need to not only track your macros but also weigh your food. I bought a food scale on Amazon and it works great.
