It's notable that a year before his heart attack, he returned to carb consumption. Now the question is, what kind of carbs? The research shows grain consumption ups heart risks considerably.
A return to bread would be especially risky, as well as other grain consumption. This may or may not explain his particular case. If he completely neglected carb intake before, this could also potentially set him up through vascular atrophy (Though, I'm not really sure if vascular atrophy results from low energy intake or low vitamin/mineral intake. The research I've seen suggests vitamin/mineral intake is particularly important, but low energy intake would be sensible and intuitive.), and I get a strange feeling he returned to carb consumption after noticing the more unpleasant affects from prolonged neglect of carbs. On the physical exercise aspect, it's possible he exercised too much. The research shows regular excess physical activity considerably increases risks, especially if breaks and recovery isn't allowed/neglected.
I really haven't looked much into how vascular atrophy happens. I feel like I understand some of the primary causes behind vascular obstruction fairly well (Questions remain as to its relationship to physical movement, immune system and to the negative emotions.), but not entirely clear on what exactly causes atrophy. I know that anorexia can cause it as well as sedentary habits. I don't know if cortisol can cause it, which would be significant, it seems like it could but I don't know how.
Okay, let's rethink protein, fats and carbs.
Fat = C,H
Carbs = C, H and Os
Protein = C,H,N,Os
From the surface, it looks like you'd get enough theoretical carbon intake for tissue synthesis with fat and protein intake (Protein looks the most complete). I don't totally understand the need for carbs, I guess it probably is the least energy intensive form of energy intake, since it takes extra energy to convert fat to blood glucose, so it's probably the most effective form of getting energy. That might be why it's so important, it has a high energy ROI compared to fat intake.
Energy is important, because it powers tissue synthesis. You need carbon sources (And probably amino acids like that in protein) to synthesize tissue, but you also need adequate energy to power the tissue repair/synthesis. It's an open question if fat intake is sufficient for energy intake. I can think of some examples that suggest yes, but yet, almost every society depends on carbs (Healthier ones depend on vegetable starches, the less healthy ones depending on refined sources, and the least healthy depending on refined wheat.), so I don't really know if fat intake suffices. My intuition and personal experience is doubting it.
To put it simply...
Insufficient carb intake can lead to vascular atrophy. (Probably through insufficient energy for vascular repair/synthesis, possibly by other mechanisms.)
Excessive refined carb intake(Bread especially) can lead to vascular obstruction. Excessive fruit sugar intake might have a similar affect, just like excessive wine intake. (I still need to measure my blood pressure curve after eating 4 apples. This would be telling about the downfall of eating too many apples, yes.)
Those two factors can probably interact with each other in a multiplicative fashion.
Yep, this paper supports my suspicion. Low carb = bad for vascular health.

Suspect that sufficient carb + high protein would be no problem, since there's enough energy to power tissue repair/synthesis.
It seems that sufficient carb + some protein is all that's really needed, since not much protein is needed for maintenance (Government recommends 55g/day, about 200 calories a day, which is 10% of a 2000 calorie diet, which is exactly the protein intake of the kitivan.).

Okay, so I'm going to start consuming vitamin D3 food sources.
Looks like cod liver oil and mushrooms (Looks like portabello and Maitake are particularly high.) are viable sources. Cheese would be great, but I'd need to store it from the heat. Guess I'll go get a container for that purpose, and just bury it in the shade. Think maybe I'll cover the hole with plywood, to try to help insulate the "outside air" from the "soil air" (Which should be cooler).
And for vitamin B12, guess I'll have to choose wisely (Meats, seafood and dairy products). Cheese would be a great source, if only I could store it.

Good carbohydrates: whole wheat or multigrain breads, brown rice, fruits, vegetables, and oats. - See more at: http://www.rachaelrayshow.com/lifestyle/health/23732_bob_harper_macro_diet_plan/#sthash.BUy1oAWh.dpuf

The cardiovascular complications of obesity have prompted interest in dietary interventions to reduce weight, including low-carbohydrate diets that are generally high in protein and fat. However, little is known about the long-term effects of these diets on vascular health. We examined the cardiovascular effects of a low-carbohydrate, high-protein diet (LCHP) in the ApoE−/− mouse model of atherosclerosis and in a model of ischemia-induced neovascularization. Mice on a LCHP were compared with mice maintained on either the standard chow diet (SC) or the Western diet (WD) which contains comparable fat and cholesterol to the LCHP. LCHP-fed mice developed more aortic atherosclerosis and had an impaired ability to generate new vessels in response to tissue ischemia. These changes were not explained by alterations in serum cholesterol, inflammatory mediators or infiltrates, or oxidative stress. The LCHP diet substantially reduced the number of bone marrow and peripheral blood endothelial progenitor cells (EPCs), a marker of vascular regenerative capacity. EPCs from mice on a LCHP diet also manifest lower levels of activated (phosphorylated) Akt, a serine-threonine kinase important in EPC mobilization, proliferation, and survival. Taken together, these data demonstrate that in animal models LCHP diets have adverse vascular effects not reflected in serum markers and that nonlipid macronutrients can modulate vascular progenitor cells and pathophysiology.
