This essay from the Yale-Griffin Prevention Research Center which puts focus on preventive medicine looks at the food we eat in a different way. In order to have a real conversation on food it says ignore the latest fads on nutrition on keto, paleo or other diets, and think about how our ancestors ate in a healthy way that both prevented disease and provided the right nutrition. It was mostly plants as meat was not freely and easily available. So much so that the consumption of meat and animal protein may have gone up by as much as 90% today. Processed foods did not exist, and unprocessed plant foods were there in abundance. They were not called low fat low carb or vegan then. It is during the beginning of the 19th and in the 20th century that the production and marketing of shelf stable, nutrient poor, high calorie, high sugar and salt processed foods replaced the normal way our ancestors had their food leading to the public health crisis of today, both in health quality, outcomes and cost.  It says replace meat and where appropriate dairy healthier plant based beans, lentils, whole grains, and vegetables, fruits so that animal protein gets back to the levels of the centuries before the 20th century shift to processed foods. It says use common sense beans including soyabeans and lentil beans replace meat wherever possible and oats with berries and nuts replace eggs. Vegetable and garbanzo beans salad replaces cheese and yogurt reducing the cheese or yogurt to very moderate levels. Focus on wholesome food and eat like our ancestors did and exercize then everything else will fall into place. ...

Zaraska says a vegetarian diet or one that includes vegetarian diet in meals is a good idea to reduce the risk of heart disease, obesity, diabetes and other medical problems. Be sure to add zinc, iron and calcium, Vitamin B12 to the diet if you are older she points out, to compensate for the change. About 2.5 million Americans over the age of 55 are vegetarian according to a 2012 Harris poll done for the Vegetarian Resource Group. There is a common perception of vegetarianism as purely vegetable type foods. However vegetarianism in India is practiced with the inclusion of all dairy products- milk, yogurt, and buttermilk. Not only are they included, they play a significant role in the diet. Also included and playing a large role in the diet are lentils and beans which provide a significant source of protein. When the idea of vegetarianism is broadened to a more normal vegetarianism as practiced in countries like India and includes dairy, lentils and beans, the diet is able to provide most of the nutrients needed. By including this kind of vegetarian food as an integral part of the diet and reducing meat is another way the health needs of Americans facing a high rate of obesity and other medical problems can be met. If insurance companies were to give incentives for increased consumption of these vegetarian foods and lowered consumption of meat, and the public was made aware of its benefits through advertising, the cost of health care in the U.S. could be brought down....

Obesity is a problem today of global dimensions. In the U.S. this problem has reached a new high and increased U.S. risks in the face of the coronavirus. This author and her nutrition organization say the U.S. dietary guidelines put out by a government agency have failed over decades to do what they were supposed to do - guide people in the right direction to make good food choices. People at this time of the coronavirus need to make their own choices, independent of these guidelines that have failed. Intuitive choices for healthy eating by increasing vegetables and fruits in the diet, increasing use of healthy herbs such as turmeric, basil and ginger, eating carbohydrates and fat in a sensible way, increasing ancient whole grains in the diet, reducing meat in the diet in favor of plant based foods such as lentils and a large variety of whole grains.

The state of India's fight against Tuberculosis is shown here by AID's Atul Gawande in NYT. He visits a homeless shelter in New Delhi and asks what can be done to prevent the number one infectious disease in India and globally. The disease affects 1 in 38000 in the US and 1 in 500 in India a huge contrast as poverty and poor health conditions increase spread of TB. It grows with depleted immune systems and poor food intake. This alone shows how important it was and continues to be that prime minister Modi put forward no cost (free) allocation of foodgrains, lentils and vegetables during the pandemic to hundreds of millions of needy households. This and Clean India campaign Swacch Bharat + Har Ghar Jal Clean Water Every Household  play a critical role in providing the basic environment for health in India at the ground level for nutrition+ clean water, and sanitation. India has allocated $1.7 billion for TB prevention and treatment. 4-5 TB vaccines are in test stages.  Nearly 90 percent of estimated TB cases are now being diagnosed with treatment success rates high, says Gawande. Prevention is also at a similar level.   ...

This excellent article by Peta Bee looks at how we can do anti-ageing efforts to keep our immune systems strong as we become older. She looks at work by an expert in immune cell biology, Janet Lord, who is head of the Institute for Inflammation and Ageing at Birmingham University. It is now proven that the link between ageing and immune systems can be guided in constructive ways. At sixty and seventy years age one can have the immune system of a 30 year old by doing a couple of simple things which are covered here from taking 10,000 steps a day, high intensity interval training on some days each month, occasional fasting on some days, high fibre diet and vitamin D. Walking, running or other forms of exercize affect a particular form of immune function called neutrophil movement in positive ways. Neutrophil movement because these cells are the main defense against the forms of bacteria that cause pneumonia. Neutrophils in older adults behaved in ways similar to that found in 30 year olds when doing 10,000 steps a day of exercize. Dr. Lord and other researchers have found. Dr. Jenna Macciochi, a lecturer in immunology at the University of Sussex, says about 70% of our immune system resides in our gut, making gut health very important for our immunity. Macciochi is the author of Immunity: The Science of Staying Well. Important for gut or gastrointestinal health is the eating of food that has prebiotic and probiotic effect. This helps reverse the decline of immunity coming with ageing.When we chew down on fibre in vegetables, fruit, beans or lentils we have beneficial byproducts called postbiotics that act as an interface between diet and immunity, that change the personalities of cells and circulate in our blood for regulation of immune system, says Dr. Macciochi. Postbiotics from eating dietary fibre tune up specific virus fighting cells that help us fight infections from flu and viruses, studies show says this report in The Times. Women in the UK get only 17g per day, men 20 mg per day of fibre. We need 30 mg per day of fibre and to do this we need to increase our intake of vegetables, fruits, whole grains, nuts, seeds and pulses. Also important is avoiding the inflammation that comes with ageing called inflammageing, says Dr. Macciochi. To do this do resistance training, weights, or using body weight such as lunges, push ups, squats. When our muscles move we produce hormones called myokines that help our immune cells function and keep inflammation down. She believes strength work is an absolute essential to rejuvenate our immune age. ...

Only 23% of meals in America include a vegetable. The number of dinners made at home with a salad dropped to 17% in 2010 compared to 22% in 1994. Salads ordered at restaurants dropped to 5% in 2010 from 10% in 1989, according to NPD research company in its 25th edition of "Eating Patterns in America." The U.S. is going backwards in good eating habits and no enough attention is being paid to this in the debate about cost of health care. Their is a clear connection between good eating habits and health, and while invention and use of the latest research and innovations in health care are lauded, the decline in patterns of healthy living and food habits are receiving less attention.

Judith Warner coins the phrase "dysregulation," for the cultural phenomena that may be behind the lack of restraint exercized in everthing that relates to personal lives like obesity, to the lack of regulation in the gulf and financial crisis. Citing Whybrow's book, "American Mania: When More Is Not Enough," she points to a disturbance in the national psyche, something that disturbs some inner clock or mechanism, that disturbs some inner balance that is built into us from the beginnings of man in the universe.
