New Scientist – The biggest immune organ is our gut and what we eat can support a healthy immune response. From eating the rainbow, consuming more fermented foods or fasting longer overnight, King’s College epidemiologist Tim Spector has top tips to boost your immunity through what you eat.
Elimination diets … Fish oil and heart arrythmia
Q: What is an elimination diet? Can it be used for weight loss?
A: Alicia Romano, MS, RD, CSNC, a registered dietitian/nutritionist with the Frances Stern Nutrition Center who specializes in gastrointestinal diseases and food allergies, answers: “I’m glad you asked this question! Elimination diets are sometimes used as diagnostic or treatment tools. They are not for weight loss.
Using common items makes it easy to know how much food you’re really eating.
The American Heart Association (AHA) recently revised its checklist for achieving optimal heart health, introducing its new Life’s Essential 8. The list replaces the AHA’s decade-old Life’s Simple 7.
Sleep health is the new addition to the cardiovascular health scoring tool, which now advises that adults get seven to nine hours per night. The organization updated four of the categories:
- Diet: More emphasis was given to following heart-healthy diets like the DASH and Mediterranean.
- Nicotine exposure: Secondhand smoke and vaping were added as risk factors.
- Blood lipids: People now can get a non-fasting blood sample that measures total, HDL, and non-HDL cholesterol. Non-HDL cholesterol can provide similar risk information as LDL cholesterol.
- Blood sugar: Measurements now include hemoglobin A1c, a key component to assessing type 2 diabetes risk.
- Three categories were unchanged:
- Physical activity: The optimal weekly level is at least 150 minutes of moderate activity or 75 minutes of vigorous activity.
- Body mass index (BMI): A BMI of 18.5 to 24.9 is ideal for heart health.
- Blood pressure: Levels less than 120/80 millimeters of mercury (mm Hg) remain optimal. Stage 1 hypertension is 130 to 139 mm Hg for systolic pressure (the first number) or 80 to 89 mm Hg for diastolic pressure (the second number).
- You can calculate your heart health score at mlc.heart.org. The guidelines were published online June 29, 2022, by Circulation.
Consuming just a half-tablespoon or more of olive oil a day is linked to a lower risk of dying from heart disease and other chronic health conditions, new research suggests.
The study included more than 92,000 women and men from the Nurses’ Health Study and the Health Professionals Follow-up Study, who filled out diet questionnaires every four years for 28 years. Olive oil intake was calculated from how much they reported using in salad dressings, on bread and other food, and in baking or frying.
Compared with participants who rarely or never consumed olive oil, those who consumed the most (about a half-tablespoon or more daily) had a 19% lower risk of dying from heart disease during the study. Researchers also noted lower death rates over all among people who substituted olive oil for a similar amount of margarine, butter, mayonnaise, or dairy fat. The findings, published Jan.18, 2022, in the Journal of the American College of Cardiology, lend further support for choosing olive oil — a key component of the heart-friendly Mediterranean diet.
Recent medical advances in the treatment of cancer you have been amazing. Many of these advances have taken advantage of our own immune system‘s and fighting the cancer. If you or a loved one have had the recent diagnosis of cancer, there are several general things that you should know.
The amazing technological advances in medicine have a come with a price tag, more than just the astronomical cost.
Preventative medicine it is given little attention in the medical profession these days, it wasn’t that great in the past either. The reason? Doctors don’t get paid to prevent disease; they get paid for treating it, and doctors are merely human beings like the rest of us and have a fondness for making money. Besides, the individual patient never knows whether he would’ve gotten the disease, had he not tried to prevent it. It takes a large number of people in a planned study to discern that.
Sleep, diet and exercise have all been casualties.
If you have established cancer, your tendency will be to give up on any exercise that you have been doing. This is an error. Depression is very common in patients with cancer, and inactivity makes it worse. Exercise is the one of the best things you can do for depression, and it may well benefit cancer itself. To be sure to ask your doctor directly about this.
Diet is also extremely important. Many Cancers produce substances that kill the appetite. Weight loss in cancer is one of the hallmarks of the disease. It becomes very important to maintain a good diet.
Sleep is also very important. Just a day or two with poor sleep can harm the Immune cells, and with immune system damage, cancer can only worsen.
Drug studies improve medical care. They also deliver care free of charge, except for your time in taking part in the study. The usual Cancer study compares the new drug with established treatment. There is minimal worry that you are going to be getting a sham treatment.
Certain medical centers are known to specialize in certain areas of cancer treatment. For instance, in Southern California, the University of San Diego is known to be a Center that treats pancreatic cancer. The city of Hope in Los Angeles is known to be a center specializing in CAR-T cell treatment, A promising if expensive treatment for pancreatic cancer.
It is very definitely worth your while to check into the availability of specialized care centers and drug studies in your area.
One of my friends developed melanoma and was told by his doctor to get his affairs in order. This absurd statement was made by a cancer doctor in one of the best hospitals in our area. In checking with an oncologist of my acquaintance, I found that a mere 30 miles away was a center specialized in the treatment of Malignant Melanoma. He went to the center for treatment, and was given a drug called a checkpoint inhibitor. He was virtually asymptomatic in a year. Unfortunately, patients can rarely expect such dramatic results.
In the history of the world, it has never been easier to learn about your disease, in this case cancer, and participate in its treatment. Especially in medicine, the best is none too good; it pays to do your homework, or at least find a medical advocate who will pursue your cause.
ess than 7% of the U.S. adult population has good cardiometabolic health, a devastating health crisis requiring urgent action, according to research led by a team from the Friedman School of Nutrition Science and Policy at Tufts University in a pioneering perspective on cardiometabolic health trends and disparities published in the July 12 issue of the Journal of the American College of Cardiology. Their team also included researchers from Tufts Medical Center.
Researchers evaluated Americans across five components of health: levels of blood pressure, blood sugar, blood cholesterol, adiposity (overweight and obesity), and presence or absence of cardiovascular disease (heart attack, stroke, etc.). They found that only 6.8 percent of U.S. adults had optimal levels of all five components as of 2017-2018.

Fiber is known for keeping your digestive system healthy and lowering cholesterol levels. Now, study findings suggest it also may protect the brain from dementia.
The study involved approximately 3,700 healthy adults, ages 40 to 64, who completed routine dietary surveys for 16 years. Researchers then monitored the participants for two decades to see which ones developed dementia. The study revealed that people who consumed the most daily fiber had the lowest rates of dementia. The reverse also was true — those who ate the least fiber had the highest rates. Specifically, the low-risk group consumed an average of 20 grams daily, while those with the highest risk averaged only 8 grams. (The USDA recommends that men over age 50 eat 30 grams of fiber daily.)
