The Healthiest Foods: Fruits, Vegetables, and Whole Grains

The best foods are plant foods because they have no cholesterol and they are low in saturated fats. On top of that, they have fiber, which has no calories and is beneficial.
My Mother died of an atherosclerotic stroke in the brain. Her cholesterol was too high.

Unfortunately coffee contains caffeine as well as phenolic acids. The caffeine raises the intraocular pressure, which is bad for glaucoma. It also irritates the stomach. The acids are bad for acid reflux.

Unfortunately delicious coffee can cause heartburn due to the phenolic acids it contains.

Statin Drugs
Statin drugs can reduce your cholesterol, but they also can have problems. There are interactions including with other drugs (1) and with grapefruit or grapefruit juice. The interaction with grapefruit makes the drug too strong.
Sodium
Unfortunately sodium intake is a risk factor for hypertension, which in turn is a risk factor for stroke, death, and other problems (including loss of eyesight).

Sodium is high in the following foods (2):
Anchovies, bacon, beef, bologna, bran, butter, Canadian bacon, clams, corned beef, dulse, green beans, green olives, ham, Irish moss, kelp, margarine, meat, milk, poultry, rose hips, salt, sardines, seafood, tomatoes. Supplements: Baking soda, monosodium glutamate, sodium ascorbate, sodium chloride.
Beware of certain over-the-counter medicines including stool softeners. These can contain sodium.

Potassium
Potassium is considered antihypertensive (2). This means that in most situations it is a good guy. The exception would be if your potassium level is too high. Potassium increases the metabolism and is thought to be helpful in stroke prevention (2).
Potassium is high in the following foods (2):
Almonds, apricots, avocados, bananas, beef, bran, Brazil nuts, brewer's yeast, broccoli, brown rice, cabbage herb, cashews, celery herb, chard, citrus fruit, dairy foods, dates, figs, fish, fruit, garlic, grapefruit juice, green leafy vegetables, guava, legumes, lentils, meat, milk, molasses, nectarine, nuts, oranges, parsley, parsnips, peanuts, peaches, pork, potatoes, poultry, raisins, rice bran, sardines, seaweed, seeds, soybeans, spinach (fresh), squash, sunflower seeds, tomato juice, veal, walnuts, wheat bran, whole grains, yams. Supplements: potassium ascorbate, potassium aspartate, potassium benzoate, potassium carbonate, potassium chloride, potassium gluconate, potassium hydroxide.
However, some of these foods are also high in sodium. Canned meats and canned fish are often packed with sodium as a preservative. They should be avoided. Seaweed has both sodium and potassium and therefore should be avoided.
Organic Foods
Organic foods are the best because they are not supposed to have preservatives. Sodium is often used as a preservative. Monosodium glutamate is used in some Chinese foods and some American foods. Avoid these foods.
Conclusions
There is an excellent website run by the Heart Failure Society of America. The URL is www.hfsa.org . This site provides more detailed information on the low-sodium, low-fat, high potassium diet to reduce hypertension. Shop in the produce section. Many canned goods have sodium added as a preservative. Avoid popcorn and potatoe chips and corn chips. These have a great deal of sodium in them as well as fat. In general it is good to avoid junk foods.
If people like this post, I could write another one providing more details of the diet. The diet is supposed to prevent heart failure and treat it. Heart failure does not mean that your heart stops beating. In medical terminology heart failure is a situation when your heart beats far too fast. It is an extreme case of tachycardia.
The general rule for potassium is that it tends to be high in fruits, vegetables, and whole grains. These are the best foods to eat. Read the labels on processed foods. Do this before you buy the food.
