Fish delivery and more
I have Bluefin tuna from Japan. It is called Tenku-Maguro, 100% farm raised tuna. Kinki University made up this 100% farming system. It took 32 years to establish. This is totally different from other farm raised tuna. You have to try it.
Many fish are available this week. I had Fish Omakase yesterday. I’ve been doing this for 2 months. And this is the last supply. People get bored to eat this omakase fish.Uni is fine, there is no problem. The Masters is coming next week, I am ready for it.
We will be closed on April 8th Monday Dinner. I have to go to Augusta to see The Masters players, this is my Spring Break.
Low calcium hormone disease risk
Having too little calcium in the diet increases women's risk of a hormone condition that can cause bone fractures and kidney stones, scientists suggest.
Primary hyperparathyroidism (PHPT) affects around one in 800 people during their lifetime and is most common in post-menopausal women.
Writing in the British Medical Journal, the team suggest increasing calcium intake cuts the risk of the disease.
Adults need around 700mg of calcium a day.
Milk and other dairy foods, nuts and fish such as sardines and pilchards (where the bones are eaten) are some dietary sources of calcium.
Taking too much could cause stomach pains and diarrhoea.
PHPT is caused by overactive parathyroid glands secreting too much parathyroid hormone.
As well as bone and kidney problems, there have also been suggestions it is linked to an increased risk of high blood pressure, heart attack and stroke.
The US team from Brigham and Women's Hospital looked at 58,300 women who were taking part in a much broader ongoing piece of research called the Nurses' Health Study.All were aged between 39 and 66 in 1986, when the study began, and had no history of PHPT.
The women have completed food questionnaires to record how frequently they ate particular foods or supplements - including calcium - every four years, with the latest being completed in 2008.Over that 22 year period, 277 cases of PHPT were confirmed.
The researchers divided all the women into five groups , depending on the calcium intake.They accounted for factors such as age, body mass and ethnicity.
It was found those with the highest intake of dietary calcium had a 44% reduced risk of developing PHPT compared with the group with the lowest.Writing in the journal, the team led by Dr Julie Paik, said: "Increased calcium intake, including both dietary and supplemental calcium, is independently associated with a reduced risk of developing primary hyperparathyroidism in women."
James Norman, of the Norman Parathyroid Center in Florida, added that daily calcium supplements in "modest doses" were likely to provide "more benefits than risks".But experts in the UK say people should be able to get the calcium they need from their diets.
Calcium Supplements May Raise Heart RisksMany people who take corticosteroids for inflammatory forms of arthritis also take calcium supplements to prevent bone loss and fracture. But there is evidence the supplements can increase risk of heart attack and stroke.
“The study suggests that calcium supplements do more harm in the form of heart attacks and strokes than they do good in the form of fractures prevented,” says lead author Ian Reid, MD, professor of medicine and endocrinology at the University of Auckland in New Zealand."We should get calcium from food, as dietary calcium does not appear to increase the risk of heart disease," he adds.
The evidence raises questions for millions of older women who take calcium supplements to keep bones strong and help ward off osteoporosis. And it may be of particular concern for those on corticosteroids, which decrease absorption of calcium by the intestines while increasing excretion of calcium through the kidneys.Dr. Reid and other medical experts agree it’s important to talk to your doctor about your specific calcium needs, what supplements you take – for instance, if you take a multivitamin and a calcium supplement – and what your diet generally includes. These factors can impact your doctor’s recommendation.
In 2007, researchers from the Women's Health Initiative Calcium/Vitamin D Supplementation trial reported no increase in heart risks associated with calcium supplements among more than 36,000 women followed for seven years. But more than half of the women in the study were taking calcium supplements on their own before the trial began, which might have masked the findings.So Dr. Reid and colleagues looked only at the subset of 16,718 women who had not been taking supplements at the start of the trial. Results showed that among this group, those assigned to take calcium and vitamin D had a 13 to 22 percent higher risk of heart attack and stroke. Women taking placebo had no increase in risk.
Further analyses that incorporated data from 13 other trials involving a total of about 29,000 women showed consistent findings. Overall, women taking supplements were at about 25 to 30 percent increased risk for heart attack and 15 to 20 percent increased risk for stroke."In our analysis, treating 1,000 patients with calcium or calcium and vitamin D for five years would cause an additional six [heart attacks] or strokes and prevent only three fractures," Dr. Reid says.
The researchers hypothesize that the sudden spike in blood calcium levels when starting a supplement causes a lying down of calcium in the artery walls that leads to hardening of the arteries, a major cause of heart attack and stroke.We can take calcium from daily, Salmon, Tofu, Rhubarb, Sardines, Collard greens, Spinach, Turnip greens, Okra, White beans, Baked beans, Broccoli, Peas, Brussel sprouts, Sesame seeds, Bok choy, Almonds.
